While you can choose between an air and AIO CPU cooler, opting for an air cooler isn’t recommended for a flagship processor, as an AIO cooler would be a much better fit due to its superior cooling performance. While the 170W TDP isn’t near the competition’s alternatives, when we tested the Ryzen 9 9950X with PBO enabled, we experienced thermal throttling, and our 240mm AIO CPU cooler faced difficulty keeping it cool. We've selected some models below that should enable you to overclock this processor for extreme output and provide a better overhead than an air cooler.

Best CPU cooler for Ryzen 9 9950X3D: at a glance

How we picked

Our selections aren’t based on on-box specifications; instead, we take a hands-on approach and test the limits of each CPU cooler by running it against various benchmarking software like Aida64 and CPU-Z. You can learn more about how we test CPU coolers in-depth and how we review and select products. 

In addition, we look at the CPU cooler’s brand, price, dimensions, and installation process. As this component will remain the same for the next few years, it needs to be invested in wisely.

Best CPU Cooler for Ryzen 9 9950X3D: Our top picks

Offering excellent performance and value, we recommend the Cooler Master MasterLiquid 360 Atmos to use with the Ryzen 9 9950X3D to keep it tame. This AIO cooler is a good option because it delivers the same or better performance than its alternatives but at a lower price point. 

In our MasterLiquid 360 Atmos review, we stress-tested the Intel Core i5-14600K, which has a maximum TDP of 181W, which is 11W more than the 9950X3D. Before starting the test, we checked the idle CPU temperature and the air behind the fans, which came around 37°C and 24.6°C, respectively. When we fired up Aida, a stress testing software, the CPU’s temperature ramped to 77°C, and the fans' air expelled only increased to 27.8°C.

This shows how good this cooler is at transferring the heat, and 77°C isn’t out of the ordinary for a CPU, especially when you’re running Aida, as it takes the processor to its utmost limit. 

As for the specifications and build quality of this cooler, it has three 120mm fans that come pre-installed to the radiator and have a maximum RPM of 2,500. Despite that, it has a noise output of 27.2 dB(A), meaning that it is quieter than a whisper, and you won’t be bothered by it while gaming, working, or streaming. 

This is a very affordable cooler that really brings in bang for the buck performance. It has a nice sleek aesthetic and it comes in two colours to choose from.

The tubes that carry the liquid from the cooling block to the radiator are made of sleeved rubber, meaning they should be robust and avoid cracks or leaks, which is essential for an AIO cooler because if the tubes leak, the cooler, for the most part, becomes useless. 

Unlike other CPU coolers, there is no LCD on the cooling block, but it offers a clear panel through which you can see the heatsink inside it and watch the inner workings of it. There is some RGB on the edges of the block, which can be turned off if you’re aiming for a non-RGB gaming setup. 

Overall, the MasterLiquid 360 Atmos managed to keep the 14600K at a very comfortable temperature, and it was also very easy to set up. So, it should also deliver excellent cooling performance while paired with the 9950X3D. To ensure that you’ve covered every avenue, we recommend using the best thermal paste to ensure efficient transfer from the CPU to the block. 

What users say

According to Amazon reviews, this cooler has excellent cooling performance, build quality, value for money, and aesthetics. One reviewer said: “I installed this on an i9-14900k with a Thermal Grizzly contact plate and Arctic mx-6 thermal compound, and even in Cinebench it doesn't go above 78°c. In the heaviest of gaming it has been at 55°. Absolutely fantastic temps with this. Very quiet, and also beautiful. 5 stars.”

If you’re looking for a CPU cooler for the Ryzen 9 9950X3D with a shorter radiator for a smaller PC case that doesn’t compromise the cooling performance, we recommend you check out the ASUS ROG Ryuo III 240. 

This CPU cooler has two 120mm fans with a maximum speed of 2,200 RPM and a 36.54 dB(A) noise output. The reason for a higher noise level is that 120mm fans have to spin faster to expel the hot air and keep the CPU cool, while 140mm fans can deliver the same results at a lower RPM due to their size. Also, being limited to only two fans gives this cooler a higher noise output than our top pick. 

That being said, in our ASUS ROG Ryuo III 240 review, we used the same test bench with the 14600K and ran the same testing software. The idle CPU temperature was 31°C while the air temperature behind the fan was 25.9°C. 

We ran the Aida stress test, and the temperature ramped up to 77°C, which is where the MasterLiquid 360 Atmos kept it at as well, and the air behind the fans was 30.6°C, a bit higher than what we got with the 360 Atmos. 

What this means is that despite being limited to only two fans, the Ryuo III was able to go toe-to-toe with a cooler and a triple-fan radiator. 

The ASUS Ryuo is a fantastic cooler for the money and is capable of cooling far beyond the CPU we tested it on.

Besides that, it has fancy features like the CPU block featuring an Anime Matrix LED on the CPU block, which can be customized using the ASUS software. In addition, the tubes are also of good quality and feel strong but aren’t stiff, meaning you can bend them to install the radiator in the orientation you want. 

So, despite being a smaller AIO cooler, it was able to deliver good cooling output, and it also makes for a good option if you’ve got a mid-tower PC case that doesn’t support a 360mm radiator. It should work great to keep the 9950X3D and keep it from thermal throttling. However, if you’re looking to get extreme performance from this processor, the next option should be a good fit for you.

What users say

According to Amazon reviews, this ASUS ROG Ryuo III 240 has excellent build quality, value for money, and cooling performance. One user stated: “This is a great AIO cooler. I have this on an unlocked 12th gen i9 processor running at a solid 5.2 GHz no issues. Swapped thermal paste for Noctua non-conductive. Fans are really quiet, pump is basically inaudible compared to the fans even running consistently at 100%.”

For those who plan on overclocking the 9950X3D to the max and want to experience the full potential of this chip, we recommend using the ASUS ProArt LC 420. This CPU cooler has a 420mm radiator on which you install three 140mm fans with a maximum speed of 2,000 RPM. 

In short, this CPU cooler was built to keep flagship processors like the Ryzen 9 9950X3D in line, even if you’ve overclocked them. However, one thing to keep in mind is that this is a large cooler, so ensure that your PC case is compatible with it. 

In our ASUS ProArt LC 420 review, it showcased excellent performance, keeping the 14600K cool even during stress testing. The maximum temperature that the 14600K touched during Aida was 72°C, while the air behind the fan was 30.8°C. 

This difference of 5°C might not seem a lot, but it is significant, especially when you consider that this difference was during stress testing. Regarding its aesthetics, there isn’t much going on as it features an all-black design with no RGB, a perfect option for those putting together a stealth build.  

The accompanying fans are Noctua NF-A14 Industrial PPC-2000 fans, a company that is renowned for its CPU coolers and other cooling solutions. So, the entire package has a very premium look and feel to it. 

That being said, to get the full potential out of the 9950X3D, you need to ensure it doesn’t throttle, and for that, you need the best of the best, and this CPU cooler should get the job done. The only downside is that it costs more than other options but also makes up for its performance.

What users say

According to Amazon reviews, this CPU cooler has exceptional cooling performance and can keep even the toughest CPUs cool. One reviewer said: “All in all, it’s a no-nonsense cooler that handles the heat of a 14900K really well. If you’re after reliable cooling without all the RGB craziness, I’d say give it a shot. It just works, and that’s exactly what I need it to do.”

How to choose the best CPU cooler for 9950X3D? 

Like the first 9000X3D processor in the Ryzen 9000 lineup, the 9950X3D can also be overclocked, meaning its power draw and thermal output can drastically increase, requiring robust cooling solutions to keep it from thermal throttling, especially if you’re located in a hot region.

There are some factors you must consider before purchasing so you don’t overspend or underspend, which could affect the CPU’s performance. We’ve listed some of these factors below:

Compatibility 

While most CPU coolers come with installation brackets that are compatible with both Intel and AMD processors, it is still better to double-check whether they are included in the package before purchasing. 

Since the Ryzen 9 9950X3D is based on the AM5 platform, head to the tech specs page for any CPU cooler you’re considering and look for the “Compatibility” section. For example, the ROG RYUO III 240, a CPU cooler that we’ve included in this guide, is compatible with the AM5 and AM4 sockets for AMD processors and LGA 1851, 1700, 1200, and 115x sockets for Intel CPUs. 

Ambient temperature 

A crucial aspect to consider is the ambient temperature. This can impact your choice of a CPU cooler. For example, if you’re located in a region where it snows a lot and generally the temperature is cold, it means that the base temperature for various components will also be low, and keeping them should be easier. 

However, if you’re located in a hot region, it means the base temperature of your processor will be high. When you put more stress on it, it might reach its operational temperature limit sooner than it would in a cold climate. In this case, an AIO cooler or even a water block would be ideal; however, you might get away with an air cooler in a cold region.

That said, TDP isn’t the only factor we need to consider. The ambient temperature can also impact how hot or cool a CPU runs, and it's best to invest in a good CPU cooler rather than experience thermal throttling and then have to replace the cooler. There are two main types of CPU coolers: air and AIO coolers. Air coolers utilize aluminum heatsinks to transfer the heat and then dissipate it via fans; they are cheaper than AIO options but don't deliver the level of cooling you get with a liquid cooler.

On the other hand, AIO or liquid CPU coolers are more expensive but have a better cooling output as they utilize a coolant to transfer the heat from the CPU to the radiator (fans). There are different radiator sizes, such as 240mm, 360mm, or 420mm, which essentially means you'll get two 120mm fans, three 120mm fans, or three 140mm fans, respectively. The higher up you go, the more they'll cost, and you'll also have to factor in whether your PC case can accommodate a large radiator, but the cooling is unrivaled.

So, based on the performance we've seen from this CPU in our 9800X3D review, we think a decent air CPU cooler or a 240mm AIO cooler would work best with this, as it doesn't run very hot, but factoring in overclocking and ambient temperature, it is better to be safe than sorry.

Our top picks

If you want the best cooling performance without spending a lot on a CPU cooler, we recommend the Cooler Master MasterLiquid 360 Atmos. We tested and reviewed this cooler for our MasterLiquid 360 Atmos review, and it had excellent cooling performance across several tests. 

For starters, this is an AIO CPU cooler with a 360mm radiator, meaning it can fit three 120mm fans with a maximum RPM of 2,500. However, you won’t have to struggle to fit the fans on the radiator as they come preinstalled. In addition, they have a noise level of 27.2 dB(A), which, for reference, is lower than a whisper, which is generally said to have a noise level of 30 dB. 

The pump block is bulky, but that speaks to its build quality. While it doesn’t have a display that can be used to add a layer of your personality to your build, it does have some RGB, which can be turned off. 

Regarding performance, our CPU cooler test bench consists of the Intel Core i5-14600K, which has a base and turbo power of 125W and 181W, respectively, which are higher than the 9800X3D’s 120W TDP. 

This is a very affordable cooler that really brings in bang for the buck performance. It has a nice sleek aesthetic and it comes in two colours to choose from. This Cooler Master Atmos cooler is doping the company proud in both performance and build quality.

Before beginning the test, the CPU was 37°C, while the air temperature behind the fans was 24.6°C, meaning the heat transfer was very efficient with this cooler. We fired up Aida to stress test the CPU and take it to its utmost limit, which also generates a good amount of heat. 

During the stress testing, the maximum temperature was 77°C while the air behind the fans was recorded at 27.8°C, which is incredible. An increase of 3.2°C from idle shows how effective this CPU cooler was, and there was 0% thermal throttling. 

So, even if you overclock the Ryzen 7 9800X3D, this CPU cooler should ensure it runs cool and doesn’t thermal throttle. We also recommend using the best thermal paste so that you can set aside the possibility of the 9800X3D overheating. 

The ASUS ROG Ryujin III is one of the best CPU coolers to use with the Ryzen 7 9800X3D. The only downside is that it costs more than our top pick, but its cooling performance is top-notch. In our ASUS ROG Ryujin III review, it showcased excellent cooling performance, which earned it a 4.5/5 rating.

For starters, this CPU cooler has a 240mm radiator, meaning it has two 120mm fans with a maximum RPM of 2,000. While this might seem fast, 120mm fans have to spin faster to dissipate the heat efficiently, while 140mm fans can get the same cooling effect at a relatively slower RPM, like 1800 or 1600.

That being said, its fan produces a noise output of 36.54dB(A), which might put off some people, but the general consensus is that 30 decibels is equivalent to someone whispering near you. So, 36 decibels is slightly above that, and with any level of ambient noise in your room or office, you won't even hear the radiator fans spinning.

The ASUS ROG Ryujin is a fantastic cooler that looks the part as well as plays it. It manages to keep our 14600K cool in every scenario, which is the most important factor when it comes to CPU coolers.

The water block has a robust and industrial look with a 3.5" LCD, which you can customize to showcase memes, gifs, or pictures, giving a touch of your personality to your rig. Besides that, it has an 8th-generation Asetek pump, which has an operation limit of 3,600 RPM, meaning fast movement of the liquid carrying the heat to the radiator.

To test its performance, we paired it with the Intel Core i5-14600K. This CPU has a max TDP of 181W, while the 9800X3D tops out at 120W. However, depending on the workload, it can exceed, as we've seen happen during plenty of our CPU and GPU stress testing.

Before starting the stress test, the idle temperature of the 14600K was 31°C, and during the test, it ramped up to 77°C, which is perfectly fine for a CPU as they have an operational limit of 95°C or 100°C. Besides that, during Blender, it remained even cooler with a maximum temperature of 72°C.

So, the ASUS ROG Ryujin III did an excellent job of keeping the 14600K cool even under immense load, and we expect it to deliver the same level of performance as the 9800X3D. That being said, the Ryzen 9000 processors are energy efficient and don't generate a lot of heat, but investing in a robust CPU cooler keeps your options open for the future as well.

For those operating on a budget, we recommend the Noctua NH-D15. It is an air cooler with good performance that doesn’t burn a hole in your pocket. During our Noctua NH-D15 review, it managed to keep the 14600K well below its maximum temperature limit, which speaks to its effectiveness. 

This CPU cooler has a copper cold plate and features two 140mm fans with a maximum RPM of 1,500. These fans have a noise level of 24.6 dB(A), meaning even if they are running at full speed, you shouldn’t be bothered, as they are quieter than a whisper. 

It also has dual aluminum heatsinks, each containing six vapor chamber heat pipes, for a total of 12 heat pipes. The CPU contact plate also comes pre-applied with high-quality thermal paste, which is great as you can simply take it out of the box and mount it on top of your CPU. 

The NH-D15 from Noctua is a fantastic cooler with a brilliant value for money, it is capable of cooling many CPUs in the higher end thanks to it’s double stack heatsink and dual 140mm fans.

The only aspect you need to be careful of is the aluminum heatsinks, as they can be sharp. Many Amazon users have also highlighted this in their reviews. Regarding its cooling performance, the 14600K has an idle temperature of 34°C while the temperature behind the fans was 27.5°C. 

During the Aida stress testing, the maximum temperature of the 14600K reached 86°C while the temperature behind the fan was 28.8°C. This means the fans, heatsinks, and heat pipes efficiently disperse the heat. There was also no thermal throttling, meaning the CPU performance didn’t suffer from performance degradation. 

The ASUS ProArt LC 420 CPU cooler is the best of the best when it comes to coolers. It can keep the Ryzen 7 9800X3D or any other processor running cool without any issues. That said, this is an expensive cooler, but its performance makes it a worthwhile investment. 

We tested and reviewed the ProArt LC 420, which kept the 14600K as cool as a cucumber. This is courtesy of its three 140mm fans running at 2,000 RPM. These have a noise level of 31.5 dB(A), which is pretty quiet and shouldn’t bother you during working, gaming, or streaming. 

The tubes are made of sleeved rubber, which should ensure that they don’t break during or after installation and that you can install the radiator in the orientation you prefer. Besides that, it is pretty easy to install: You simply have to connect the fans to the radiator, attach it to the casing, mount the pump block on top of the CPU, and connect the necessary wires. 

The ProArt is a fantastic cooler designed to be utilized by creatives, or people who regularly put a lot of strain onto their CPU. This cooler is designed to be the best, and integrate seamlessly into any PC case that can accommodate is huge 420mm radiator.

Regarding its cooling performance, the same test bench was used. The 14600K had an idle temperature of 33°C, with the air temperature behind the fans coming around 27.8°C. When we started the stress test, the maximum CPU temperature was recorded at 72°C while the average CPU core temperature was 57°C. Besides that, the air temperature behind the fan was 27.8°C with 0% thermal throttling. 

So, this cooler is most likely overkill for the 14600K, but it makes for a good investment for more powerful processors like the 14900K, 9950X, and even the 9800X3D, as it can keep even the hot-headed processor cool. One aspect to keep in mind is that this cooler has a 420mm radiator, meaning it'll require a big PC case to accommodate it. So, before purchasing, confirm whether your PC case has enough space to house this cooler, and if it doesn't, you'll have to buy a new PC case.

If you're looking for a CPU cooler on a budget or just want a placeholder till the one you want comes back in stock, we recommend the APNX AP1-V. This CPU cooler costs less than $50, and we've reviewed it in-house, and it has decent cooling performance for the price point.

This CPU cooler features a 120mm fan with a maximum speed of 1800 RPM. This is normal, as smaller fans need to run faster to provide better cooling. 140mm fans generally have a slower RPM as they don't need to run as fast, but can provide good cooling. It also has a noise level of 16.1 to 32.8 dB(A), which shouldn't be too much, as a whisper is believed to be around 30 dB. So, you probably won't hear it running while you're working or gaming.

This is a fantastic bang for the buck cooler that is easy to install and does a decent job at keeping the 14600K cool. There’s not a lot of thermal headroom available to upgrade CPUs, however, so that is something to consider. Overall, for the price, this cooler does well.

The cooler is a complete package, meaning you can take it out of the box, mount it, and start working. You don't need to attach any fans to the heatsink, which has the risk of cutting you, but the downside to this integrated fan is that if it malfunctions, there is no way to get it fixed.

As for its cooling performance, we paired it with the 14600K, which has a base TDP of 125W and a maximum power draw of 181W, whereas the 9800X3D sits at 120W. That being said, the idle temperature of the 14600K was 40°C with 0% throttle. We ran an AIDA stress test to take this CPU to its utmost limit, and during that, the maximum temperature was 86°C with 0% throttle.

So, for an extremely pocket-friendly CPU cooler, it has amazing cooling performance and should do a good job with the Ryzen 7 9800X3D. That being said, you might experience higher temperatures if you overclock the 9800X3D, but generally, the Ryzen 9000 lineup has good efficiency.

How to choose the best CPU cooler for 9800X3D

The Ryzen 7 9800XD is the first X3D processor in the Ryzen 9000 series, and it can be overclocked. Depending on that and the ambient temperature and workload, it might need robust cooling solutions, but spending top dollar on a fancy cooler isn’t a solution for everyone. 

There are some factors you must consider before purchasing so you don’t overspend or underspend, which could affect the CPU’s performance. We’ve listed some of these factors below:

Budget 

First and foremost, you need to consider your budget and filter the available options based on that. There are plenty of CPU coolers that offer RGB fans, a screen on the pump block, and other bells and whistles, but all of these come at a cost. 

So, if you’re operating on a budget, filter the options and select the one that offers the best value and keeps your CPU cool. If your budget does not limit you, then you can get the best AIO CPU cooler and call it a day, as these coolers can handle powerful CPUs and keep their temperature under control. So, it also serves as an investment because if you upgrade, as long as the mount is compatible, you can keep using the same cooler. 

There is a huge difference in cost when it comes to CPU coolers, as an air cooler can cost you under $50, like the Thermalright Peerless Assassin, which is available on Amazon for $38.90. On the other hand, according to Camelcamelcamel, the best price for an AIO CPU cooler like the CORSAIR Nautilus 360 is $122.90.

So, it ultimately depends on your budget, but if you've got a high-end PC and you plan to overclock your CPU, then a liquid cooler is a safer option, meaning you'll have to spend more. You can wait for sales for the prices to drop for a better deal.

Compatibility 

The Ryzen 7 9800X3D is based on the AM5 platform, which means that whichever CPU cooler you have your eye on needs to be compatible with it. Thankfully, companies manufacture coolers with mounts for Intel and AMD processors, meaning one cooler can work with multiple generations of CPUs. However, check if the cooler is compatible and comes with an AM5 mount before purchasing. 

Ambient temperature 

Your ambient temperature can impact how hot or cool your CPU runs. For example, if you operate in a hot region, the baseline for your components will automatically be high, meaning they’ll reach the peak much quicker than if they were in a cold region.

So, you’ll need to install multiple case fans and invest in a good air cooler or opt for a high-end AIO cooler. However, if you were located in a cold region, an air cooler would be fine. The outside air is cool, so the influx of cold air would keep the CPU and other components running cool.

Does the 9800X3D need a liquid cooler?

An AIO CPU cooler isn't necessary for the Ryzen 7 9800X3D, as these processors were built with efficiency in mind and run much cooler than the previous generation. So, a solid air cooler like the Noctua NH-D15 should also do a good job of keeping it tame.

However, there are other benefits of using an AIO cooler, as it reduces the clutter and gives the PC a much cleaner look, but they cost more. So, if you're willing to spend more for a clean look and better aesthetics, you can opt for an AIO cooler, but if functionality is all that you're after, an air CPU cooler should work just fine.

Does the 9800X3D come with a cooler?

No, it does not. The 9800X3D only comes with the processor in the box. It does, in fact, have a high TDP that's too much for a standard stock cooler. Those are more likely to be included in the lower-end processors, like a Ryzen 3, or cards with not as high a TDP, and that threaten thermal throttling. So you should provide a good enough cooling capacity for the 9800X3D.

Does the Ryzen 7 9800X3D run hot?

In our review of the 9800X3D, we did record the temperatures it ran at. In Cyberpunk, it achieved 61°C, and in Blender, it jumped up to 71°C, which is fairly good for running the CPU under load. However, that is with a 360mm AIO attached to the CPU, and so it manages to keep it from throttling, so it can run hot under PBO and overclocking, and can make use of bigger and better CPU coolers.

That said, while energy efficiency might have affected its gaming performance, it still has better multi-core performance than its predecessors. Also, we can’t deny that this is a powerful CPU, and if you overclock it, you’ll need to pair it with a good CPU cooler to keep the temperature under control.

We’ve selected a handful of coolers based on their price, design, compatibility, and the performance they showcased during our testing. So, without further ado, let’s get right to it. 

How we picked 

Our selections aren’t based on on-box specifications; instead, we take a hands-on approach and test the limits of each CPU cooler by running it against various benchmarking software like Aida64 and CPU-Z. You can learn more about how we test CPU coolers in-depth and how we review and select products. 

In addition, we look at the CPU cooler’s brand, price, dimensions, and installation process. As this component will remain the same for the next few years, it needs to be invested in wisely.

Our top picks

To keep the Core Ultra 9 285K operating at an optimal temperature, we recommend the ASUS ROG Ryujin III. This is an AIO CPU cooler with a 240mm radiator, meaning you can fit two 120mm fans. Also, during our in-house testing for our Ryujin III review, it kept our test bench CPU well under its maximum operating temperature. 

To begin with, this cooler has a maximum fan speed of 2,000 RPM, and its noise level during our testing was 36.54 dB(A). To give that context, a whisper is generally believed to have a noise level of 30 decibels. So, even under load, you shouldn’t get distracted by this cooler’s noise. 

This cooler's pump block has a copper CPU cold plate and an 8th-generation Asetek pump operating at 3,6000 RPM. The pump keeps the liquid flowing, and transfers heat to the radiator, so it wasn’t surprising that it kept our processor cool and comfortable. 

It also features a 3.5” LCD that is fully customizable, meaning you can display your picture, memes, gifs, or other custom animations to add a bit of your personality to your rig. A big aspect of AIO coolers is the tubes; if they are made from a weak material that can damage or crack over time, you’ll have to replace the entire cooler.

The ASUS ROG Ryujin is a fantastic cooler that looks the part as well as plays it. It manages to keep our 14600K cool in every scenario, which is the most important factor when it comes to CPU coolers.

However, the Ryujin III has sleeved rubber 40cm tubes, which are durable and long enough to allow you to install it in the orientation you want. 

Regarding its performance, we used the Intel Core i5-14600K, which has a base and maximum TDP of 125W and 181W, respectively. The Core Ultra 9 285K has a higher maximum TPD of 250W, but this should clearly show how effective this AIO cooler is. 

Before starting our test, we checked the idle CPU and air behind the fan temperature, which came to around 31°C and 28.2°C, respectively. After this, we stress-tested the 14600K using Aida, pushing the CPU to its limit. 

During the stress testing, the 14600K had a maximum temperature of 77°C, the air behind the fans was 32.1°C, and there was 0% throttling. This cooling performance is nothing short of impressive as the temperature went from 77°C to 32.1°C while traveling from the pump block to the radiator, and 77°C is a normal operating temperature for a processor and even a GPU. 

Overall, this is one of the best AIO coolers. It should prevent the Core Ultra 9 285K from overheating and ensure a smooth gaming, working, and streaming experience.

What users say

 According to Amazon reviews, this CPU cooler has excellent performance, value, and build quality. One reviewer said: “I've been looking for something to tame the beast of the i9 14900k so I decided on this. I got the noctua two fan and it's definitely keeping my temps down. At high load and gaming I get about 50-65c.”

Not everyone has the budget for an AIO cooler, as they can get expensive. However, air coolers still deliver great cooling performance and are lighter on the pocket. We recommend opting for the Noctua NH-D15, as we’ve tested and reviewed this cooler in-house, and it has great value for performance.  

For starters, this CPU cooler sports dual 140mm fans with a maximum of 1,500 RPM. This means they need to spin relatively slower than 120mm, bringing their noise level to 24.6 dB(A), significantly lower than the Ryujin III. 

It has dual aluminum heatsinks, which have six vapor chamber heat pipes going through them to transfer the heat to the heatsinks, which are then cooled by the fans. A high-quality thermal paste is also part of the package; however, you can also remove that and apply your own. If you’re interested in checking out some options, we’ve got you covered with our best thermal paste guide. 

The NH-D15 from Noctua is a fantastic cooler with a brilliant value for money, it is capable of cooling many CPUs in the higher end thanks to it’s double stack heatsink and dual 140mm fans.

The Noctua NH-D15 is also easy to install, but be careful when attaching the fans to the heatsink, as the heatsink is sharp and could potentially cut you. As for its performance, we used the same test bench as before with the 14600K. 

The idle temperature with this processor was 34°C, and the air temperature behind the fans was 27.5°C. During stress testing, the maximum temperature we recorded was 86°C, and the air temperature behind the fans was recorded at 30.2°C.

The 14600K has a maximum operating temperature of 100°C, and 84°C is well below that. The Core Ultra 9 245K’s upper limit is 105°C. So, this air cooler should be able to keep it from thermal throttling and keep it running cool. You should also experience better results since our test bench is open, meaning the airflow isn’t flowing as it would inside a case. 

Overall, this Noctua NH-D15 gets the job done without burning a hole in your pocket and is compatible with the LGa 1851 socket. 

What users say

According to Amazon reviews, this cooler has great performance, design, and value for money. One reviewer said: “This beast is a CPU-cooling masterpiece. It's incredibly quiet and will air-cool anything on the planet that isn't a Threadripper or modern Xeon, both of which are too big for the baseplate to adequately cover.”

If you want the best and are ready to invest in that, we recommend the ASUS ProArt LC 420. This is a massive AIO cooler, and it was able to keep the 14600K’s temperature well under control when we tested it for our ProArt LC 420 review. 

This AIO cooler features three 140mm fans on its radiator, and they have a maximum RPM of 2,000. On top of that, these are Noctua NF-A14 Industrial PPC-2000 fans and only have a noise level of 31.5 dB(A). 

Its all-black design shouldn’t stand out, but for RGB enthusiasts, it might be a letdown. It is also fairly easy to install: Attach the fans to the radiator, mount the pump block on the CPU, secure it in place, and you’re done. 

The ProArt is a fantastic cooler designed to be utilized by creatives, or people who regularly put a lot of strain onto their CPU. This cooler is designed to be the best, and integrate seamlessly into any PC case that can accommodate is huge 420mm radiator.

As for its cooling performance, the idle maximum temperature of the 14600K was recorded at 33°C, and the air temperature behind the fans was 27.8°C. When we started the Aida stress test, we saw the temperature rise but remained at normal levels. 

The maximum temperature was 72°C while the air temperature behind the fans was 30.8°C, and there was no thermal throttling. We also ran Blender and Handbrake ToS, and during those tests, the maximum temperature was even lower at 70°C for both. 

Overall, this CPU cooler comes with a heavy price tag, but its performance makes it a worthwhile investment. Even if you’ve overclocked the Core Ultra 9 285K, you should be able to keep it running cool. 

What users say

According to Amazon reviews, this cooler is able to keep even the hottest processors cool. One reviewer said: “So, I've been using the ASUS ProArt LC 420 AIO cooler with my i9 14900K, and it’s been rock solid. Even when I'm pushing the system hard with video rendering and gaming, the temps stay well under control—rarely going over 85°C.”

How to select the best CPU cooler for 285K 

The Core Ultra 9 286K is a powerful but efficient processor. However, that doesn’t mean it can’t overheat if not taken care of, and depending on the ambient temperature and workload, it might need robust cooling solutions, but spending top dollar on a fancy cooler isn’t a solution for everyone. There are some factors you must consider before purchasing so you don’t overspend or underspend, which could affect the CPU’s performance. We’ve listed some of these factors below:

Compatibility

The Arrow Lake processors use the LGA 1851 socket which has a completely different design from the previous socket. However, the CPU coolers compatible with the LGA 1700 socket can also be used for the Core Ultra 200S processors, meaning you won’t have to invest in a new CPU cooler or an installation bracket.  

Overclocking 

The Core Ultra 9 285K can be overclocked, meaning its clock speeds can be increased at the cost of a higher power draw and thermal output. If you plan on squeezing every bit of performance out of this processor by overclocking, you’ll also need to invest in a powerful CPU cooler to ensure that it doesn’t thermal throttle. Thermal throttling will result in a degraded performance, which beats the purpose of overclocking the CPU. 

Noise level 

Some people are okay with their rigs making some noise; after all, there are running components inside, while others want it to be whisper quiet. So, if the noise level doesn’t matter to you, you can opt for any AIO or air cooler and call it a day.

However, if you want a silent operating PC, always check the noise level of the CPU cooler before making a purchase. Coolers with bigger fans, such as 140mm instead of 120mm, have a slower RPM because they don’t need to spin as far as 120mm fans to get the same cooling result, producing less noise.

The processor has a default TDP of 105W, so it will run pretty hot, especially under load. Without proper cooling, you will run into overheating issues, which can damage the CPU in the long run.

We've reviewed a good number of CPU coolers and have put each one through intense testing to learn about their performance. Based on that, we've selected the ones that we think are the right match for the processor. So, without wasting another second, let's jump in!

How we picked

We never solely rely on online ratings and reviews, so we take a hands-on approach instead. This allows us to get an idea about the cooler's real-life performance. You can read more about how we test components to learn about our methods and process. Also, during the selection process, we keep factors such as performance, compatibility, features, and design in mind. This way, we make sure you don't end up wasting your money on the wrong cooler.

Our top picks

Air coolers are great for those who don’t want to overspend on an AIO cooler but still want something that can help keep the processor cool. And for the Ryzen 7 5800XT, you’d want to get the Noctua NH-D15. This is a premium air cooler that can keep even the hottest CPUs cool. In our in-depth Noctua NH-D15 review, the cooler delivered great performance in different stress tests.

To begin with, the NH-D15 isn’t an ordinary air cooler, as this one comes with a dual-fan design. Because of them, there are also two heatsink stacks. These two come with six copper and aluminum vapor chambers which make sure your processor stays cool in long gaming sessions. 

The fans run at a max speed of 1,500 RPM, which is pretty impressive for an air cooler. However, it’s important to note that the dual-fan design also makes the NH-D15 bigger in size. 

The Noctua cooler is certainly capable of keeping thermal throttling at bay, but the temperatures aren’t exactly AIO level, of course, that makes sense, given the fact this CPU cooler isn’t an AIO.

For our test, we used the NH-D15 on the Core i5-14600K. In the Aida stress test, which puts the CPU under a lot of pressure, the average temp was 70°C, which went up to 86°C. Considering Intel CPUs run pretty hot, the NH-D15 did an amazing job. The cooler is also pretty quiet, as it has a noise level of around 24.6 dB. 

Overall, the Noctua NH-D15 is a great choice for the Ryzen 7 5800XT. It may be expensive for an air cooler, but you won’t run into any overheating issues thanks to it.

What users say 

Amazon reviewers only have great things to say about the NH-D15. Most of the reviewers are satisfied with its cooling performance and build quality. One of them said: “The quality of packaging, cooler and everything included is excellent. It is very well made and finish is flawless.”

AIO coolers are designed for those who don’t want to compromise on the temperatures of their CPU. They also help with improving the overall look and feel of the build. For the Ryzen 7 5800XT, we’d recommend the ASUS ROG Ryujin III 240. This AIO cooler delivers exceptional performance and keeps the temps low at all items. In our ASUS ROG Ryujin III 240 review, the cooler didn’t disappoint us in terms of performance.

Like some of the best AIO coolers, the Ryujin III's 240mm radiator features two 120mm fans that can run at a max speed of 2,000 RPM. This should help your CPU stay cool even when under load. The water block also features a copper CPU cold plate and an 8th-generation Asetek pump, which will further help with keeping the temps low.

The Ryujin III also features a CPU block with a 3.5-inch screen. You can either run cool animations on the display or use it to view real-time stats of your CPU. However, the CPU block is also pretty big due to the display, so the design may not be for those who prefer minimal designs. 

This cooler is designed to look good and perform well in any system, but it’s not just a pretty face. 

To check its performance, we placed the Ryujin III 240 inside our rig, which was being powered by the Intel Core i5-14600K. The idle temperature was 28°C, while the max it went up to was 31°C. However, this was recorded when the CPU wasn’t doing anything, so we decided to launch the Aida stress test. During it, the average temp was 61°C, and the max temp was 77°C. This is incredibly impressive, considering Aida is one of the most intense tests out there. 

Overall, the ASUS ROG Ryujin III 240 is perfect for those who are willing to spend a good amount of money on an AIO cooler. Even if you decide to upgrade to a high-end processor in the future, you won’t have to worry about replacing the cooler.

What users say

On Amazon, reviewers are praising the cooler for having the ability to keep even the hottest CPUs cool. One of them said: “I've been looking for something to tame the beast of the i9-14900k so I decided on this. I got the Noctua two fan and it's definitely keeping my temps down.” 

If you’re tight on a budget and want something that won’t put a dent in your bank account but will still keep the Ryzen 7 5800XT cool under pressure, you’d want to check out the Noctua NH-L12S. This is yet another Noctua cooler on our list, and for the price it comes at, it delivers great performance. As you can see in our Noctua NH-L12S review, the cooler performs great in multiple stress tests. 

Unlike the first option on our list, the NH-L12S comes with a single 120mm fan, which can run at a max speed of up to 1,850 RPM. Thanks to the single-fan design, the cooler is pretty small and can help keep your rig's overall look clean and minimal.

To learn how it performs, we tested the Noctua NH-L12S in the same rig used for the first two coolers on our list. The idle temp was 34°C, and the max we saw was 39°C. This isn’t the best, but it’s not bad for an air cooler that falls in the budget category. 

Noctua has outdone themselves on design once again, and the fact it’s even able to remotely keep up with a CPU it was never supposed to cool is very impressive.

We then decided to increase the heat by launching the Aida64 stress test. The average temperature we recorded was 76°C, and the max it reached was 97°C. Keep in mind that Aida pushes the CPU to its limit, which you won’t be doing in your daily usage. So, you can expect to see better temps in the standard CPU-intensive applications. 

Overall, the Noctua NH-L12S is a great option for those who are looking for a budget cooler for the 7 5800XT. Make sure you're using one of the best thermal pastes with it. Also, for better cooling, we'd recommend getting one of the best airflow cases and best 140mm case fans.

What users say 

According to the reviews on Amazon, the cooler has the perfect size and great cooling performance. One of the reviewers mentioned: “I had problems with my computer overheating. I used this as an upgrade and it works great.”

How to pick the right cooler for this CPU

The cooling system in your rig helps keep the processor cool, which not only ensures smooth performance but also improves its lifespan. However, selecting the right CPU cooler isn't as easy as it sounds. Before making the final purchase, consider the following factors.

Budget

Your budget will play the most important role during the selection process. If you don't mind spending a good amount of money, then we'd recommend opting for an AIO cooler. These come with radiators and offer exceptional performance. They also help improve the overall look and feel of your rig, and some even have a small display on the CPU block. There are also some Air coolers that come with a premium price tag and offer a dual-fan design.

But if you're short on cash or are not willing to overspend on the cooler, your options might be limited to air coolers with a single fan. While their performance may not be as good as that of AIO coolers, they can still help keep the temperatures low.

Compatibility

Some CPU coolers work with either Intel or AMD processors, while others are compatible with both. You should opt for one that falls in the latter category. This is because if you decide to switch to Intel in the future, you won't have to worry about replacing your cooler. So, make sure to learn about the cooler's compatibility before hitting the buy button.

We researched multiple CPU coolers from the market, put them through our rigorous in-house testing, and put together this in-depth guide that features the coolers that made the cut. 

You’ll find their reviews, details, pros and cons–everything you need to make an informed decision. We also have you covered with our Where to Buy 5900XT page, which has multiple retailers listed in one place to save you time and effort.

How we picked

Our selections aren’t based on on-box specifications; instead, we take a hands-on approach and test the limits of each CPU cooler by running it against various benchmarking software like Aida64 and CPU-Z. You can learn more about how we test CPU coolers in-depth to get a better understanding of our selection and testing process. 

In addition, we look at the CPU cooler’s brand, price, dimensions, and installation process. As this component will remain the same for the next few years, it needs to be invested in wisely.

Our top picks

The Ryzen 9 5900XT is a buffed-up version of the 5900X and comes with a TDP of 105W, which is higher than most Ryzen 9000 series processors. However, to cool this old but new fighter, we recommend the Noctua NH-D15, as it performed excellently during our testing for its review. 

This CPU cooler is massive, with dual heatsinks and powerful 140mm fans with a maximum fan speed of 1500 RPM. It also has six aluminum and copper vapor chambers running through the heatsinks to ensure maximum heat transfer and dissipation. 

If you think 1500 RPM isn’t enough, remember that 140mm fans don’t need to spin as fast as 120mm fans to achieve the same cooling results. That said, despite having dual 140mm fans, it had a noise level of 24.6 dBA during our testing, which is very quiet. 

For the 14600K, this cooler is okay, it’ll easily cool any other CPU below 150W no matter the workload. If you can find this COU cooler for less than $90 and you aren’t trying to cool a 14900K or anything to that end, then this CPU cooler would be perfect for you.

To see how well this cooler performs, we brought in the Intel Core i5-14600K, which has a base and maximum TDP of 125W and 181W, respectively, compared to 5900XT’s 105W TDP. 

At idle, the 14600 K's maximum temperature was 34°C, and the air temperature behind the fan was 27.5°C. During the Aida stress test, which takes the CPU to its utmost operational limit, the maximum temperature was 86°C while the average CPU core temperature was 70°C. 

The air temperature behind the fans was 30.2°C, which showcases how effective this cooler is in transferring and dissipating heat. This CPU cooler also comes with pre-applied thermal paste. However, many prefer to use their tried-and-tested brands. If you’re interested in exploring options to further increase its performance, check out our best thermal paste guide for the top picks. 

Overall, the NH-D15 has excellent performance and value and should be more than enough for the Ryzen 9 5900XT if you’re looking for an air cooling option.

What users say

According to Amazon reviews, it is being praised for its build quality, cooling performance, and quiet operation. One reviewer stated: “I was able to get full overclocks on anywhere from a 8700k to a 13900k with this thing. It performs better than most AIOs I am aware of.”

For those who prefer an AIO cooler for the best cooling performance, we recommend the ASUS ROG Ryujin III. We don’t just recommend options based on the brand name, and as you’ll see in the Ryujin III 240 review, its cooling performance is second to none, which is why it's on this list. 

For starters, this cooler has dual 120mm fans that fit on the aluminum radiator and have a maximum speed of 2,000 RPM. On top of that, the pump block has an 8th-generation Asetek pump with a maximum RPM of 3600. This combination should ensure cool operation for even the toughest CPUs. 

The CPU block has a 3.5” LCD, which can display pictures, gifs, or memes. While this doesn’t impact the cooler's performance, it is certainly nice to have as it allows you to customize your build further. 

An important component of any AIO cooler is its tubes, and this one has 40cm sleeved rubber tubes. This means you should be able to install the Ryujin III in different orientations according to your PC case. 

The ASUS ROG Ryujin is a fantastic cooler that looks the part as well as plays it. It manages to keep our 14600K cool in every scenario, which is the most important factor when it comes to CPU coolers.

Regarding its performance, we used the same test bench with the 14600K, and it had an idle maximum temperature of 31°C and an average CPU core temperature of 28°C. 

After we started the Aida stress test, these figures rose to 77°C and 61°C while the air temperature behind the fan increased to 32.1°C from 28.2°C. These temperatures for a stress test are phenomenal, making the Ryujin III one of the best CPU coolers you can get your hands on. 

Many processors reach these temperatures during normal gaming, so it's safe to say that it should be able to keep the 5900XT nice and breezy even if you’ve overclocked it. However, we don’t recommend running a CPU in an overclocked state for a long as it could damage it. 

Overall, we’re very impressed with the ASUS ROG Ryujin III's cooling performance. While it may come at a premium, it is certainly worth the investment, as you should be able to upgrade to even more powerful CPUs without worrying about overheating issues. 

What users say

According to Amazon reviews, it is capable of taming even the hottest processors, and one reviewer said: “I've been looking for something to tame the beast of the i9 14900k so I decided on this. I got the noctua two fan and it's definitely keeping my temps down. At high load and gaming I get about 50-65c.”

Not everyone has hundreds of dollars to spend on a CPU cooler, and for those operating on a budget, we recommend the Noctua NH-L12S. This is the second Noctua cooler on this list, and this variant is like the toned-down version of our top pick. 

During the Noctua NH-L12S review, it showcased decent performance, and we think it should be a good fit for cooling the Ryzen 9 5900XT. 

This CPU cooler has a single 120mm fan, which has a maximum fan speed of 1800 RPM, and a single aluminum heatsink. That said, this cooler is designed to fit horizontally on the CPU instead of vertically, which we’re used to seeing. 

It also has a low-profile design, making it an excellent installation option in the best micro ATX cases. It also has four heat pipes, so given its small size and humble design, we don’t expect it to cool processors like the 13900K, which we’ve reviewed, but it should be enough for the Ryzen 9 5900XT. 

This is a cooler designed for the smallest of form factor PCs, you might struggle trying to cool higher power CPUs, but for the mid range compact solutions, look no further than the L12S.

That said, we checked how it fared against the 14600K. The idle maximum temperature was 39°C, with the average CPU core temperature around 34°C. During the Aida stress test, we saw a significant increase as the max temperature reached 98°C, with the average core temperature hovering at 78°C. 

We experienced a 5% throttle, which wasn’t surprising since this cooler wasn’t designed to handle so much heat. That said, the 5900XT has a much lower TDP than the 14600K, and if you keep it from overclocking, its temperature should be kept under control. 

Overall, this CPU cooler should be a good addition to your budget build as it doesn’t cost much and has decent hardware to tackle low TDP CPUs. 

What users say

According to Amazon reviews, users are pleased with its performance and build quality. One reviewer said: “This coolers size is perfect for itx builds or small form factors its not too noisy and has great cooling preformance can go long gaming sessions with no issues, mounting is some what difficult but easy to set up uses the stock am4 and or am5 back plate”

How to pick the best cooler for this CPU 

The processor is an integral part of any system, but its performance degrades if it gets too hot. That said, it needs to be cooled down, but spending top dollar on a fancy cooler isn’t a solution for everyone. There are some factors you must consider before purchasing so you don’t overspend or underspend, which could affect the CPU’s performance. We’ve listed some of these factors below:

Budget

The budget is the most crucial aspect when it comes to purchasing any component. So, it goes without saying that for a CPU cooler, you must also look at options your budget allows. While having a fancy AIO cooler has its appeal and excellent performance to boot, it comes with heavy price tags. 

On the other hand, air coolers are comparatively cheaper, and you’ll find options that are capable of cooling even the hottest processors. So, filter the available options based on your budget and select the one that offers the best balance between performance and value. 

Compatibility 

A big factor you should not miss is the compatibility between the CPU cooler and the casing. We recommend that you always measure the cooler's dimensions against the space available in your PC case, as if it is bigger, you won’t be able to close the side panel if it's an air cooler. If it’s an AIO cooler, the radiator might be too big to fit inside, and you’ll have to replace it.

Besides that, the 5900XT is based on the AM4 platform, so ensure the cooler is compatible with it and comes with the relevant brackets for installation.

It is an entry-level processor with a default TDP of 65W, so you don't have to worry about it generating too much heat like some of the high-end CPUs in the AMD 9000 series lineup. However, this does not mean you shouldn't opt for the best cooling solution, as keeping the temperatures low will help keep the CPU running smoothly and improve its lifespan.

We've reviewed several CPU coolers and have conducted in-house testing to get an idea about their real-life performance. Based on that, we've selected a few coolers that we think are the right fit for the processor. Also, you may want to check out the best GPUs for Ryzen 5 9600X if you're looking for a solid graphics card to pair with it.

So, without wasting another second, let's dive in! We've also listed all popular retailers offering this CPU in our Where to Buy 9600X page, so you can check them out if you want to get this processor for your rig.

How we picked

For this list, we went through several options from different brands and selected the ones that offer the best value for money. During the selection process, we considered factors such as price, performance, features, and build quality. On top of that, we never solely rely on online ratings and reviews for our lists. Instead, we conduct in-house testing of each cooler before recommending it to our readers. You can check out how we test components to learn more about our process.

Our top picks

If you’re looking for something that ticks all the boxes of a great cooler for the Ryzen 5 9600X, then we’d recommend the Noctua NH-D15. This is an Air cooler that offers a dual-fan design. In our in-depth Noctua NH-D15 review, the cooler managed to keep the temps low and performed well during the stress tests. 

Air coolers are considered affordable compared to AIO coolers, but some of the premium ones can still be a bit expensive. As for the Noctua NH-D15, it falls in the premium category, but that’s because it's different and better than most of the other Air coolers that you’ll find in the market. 

Unlike regular Air coolers that come with a single fan, the NH-D15 offers two 140mm fans paired with a dual heatsink setup. These heatsinks come with six copper and aluminum vapor chambers, which provide better heat dissipation. On top of that, its noise levels are also pretty low, 24.6 dB, which is similar to a whisper.

The NH-D15 from Noctua is a fantastic cooler with a brilliant value for money.

For our review, we tested the NH-D15 against the Intel Core i5-14600K. Intel CPUs tend to generate more heat compared to AMD CPUs, so testing the cooler with them is the best way to learn about their actual potential.

The cooler managed to keep the idle temperature at around 34°C. When we launched the Aida stress test, the temperatures stayed around 70°C for the most part, but the max we recorded was 86°C. While the results were decent, the temperatures would have been higher if we had used a top-tier processor. However, with the Ryzen 5 9600X, you can expect similar or better results.

Overall, the Noctua NH-D15 will easily help keep the Ryzen 5 9600X cool, even during intense gaming sessions. But make sure you’re using one of the best thermal pastes with it for better cooling.

What users say

According to Amazon reviews, the NH-D15 does an excellent job of keeping the CPU temperatures low. Most of them praised its build quality. One of the reviewers mentioned: "The quality of packaging, cooler and everything included is excellent. It is very well made and finish is flawless."

If budget is not an issue and you don't want to compromise on cooling, then we’d recommend the Corsair H150i ELITE LCT XT. This is an AIO cooler that can even keep the hottest CPUs cool during intense sessions. In our Corsair H150i ELITE review, we found it to be a solid cooler for both cooling and improving the overall aesthetics of your build.

To begin with, the H150i Elite boasts a 360mm aluminum painted radiator, which stores three Crosair ML120 RBG fans. These fans offer a speed of up to 2,000 RPM, something that will help keep the temps within safe levels. However, keep in mind that a 360mm radiator is large in size, and not every case can accommodate it. So, make sure your case supports it before making the purchase.

The H150i Elite also comes with a 2.1-inch LCD that further compliments the looks of the cooler. You can either view the real-time stats of your CPU or just run some cool animations on it. There’s also an RGB ring around the CPU block, which, when paired with the RGB in the fans, can help change the feel and look of your rig. These lights can be controlled using the Corsair iCUE software, which also lets you create custom lighting profiles.

The performance of this CPU cooler is very good considering we gave it the herculean task of cooling the Intel i7-14700K.

As far as the performance is concerned, we used it in our rig that was being powered by the Intel i7-14700K, which is a pretty solid processor. For the most part, the idle temp was around 27°C, and the max was 29°C. During the Aida stress test, which pushes the CPU to its limits, the average temp was 79°C, while the max it hit was 100°C. The max temp may seem alarming, but it isn’t. This is because Aida puts the processor under a lot of stress and it is the extreme end of CPU testing.

We also tested the performance of the H150i Elite in gaming. For this, we launched Days Gone and played it for around 10 minutes. The average temp was 55°C, while the max temp was 71°C.

Overall, for those who are willing to spend a little more than $200 on a CPU cooler, there is no better option than the H150i Elite for the Ryzen 5 9600X. After all, it is one of the best AIO coolers out there.

What users say

On Amazon, most reviewers are happy with their purchase. One of them said: "Works well in keeping my PC nice and cool. Normally temps hover at 31C and when gaming, it can go up to 60C."

If you’re not able to invest a significant amount of money on a CPU cooler right now and are looking for something that is budget-friendly, then you’d want to check out the APNX AP1-V. The is the first APNX cooler that we’ve reviewed, and it has definitely exceeded our expectations. In our APNX AP1-V review, we found it to be an excellent cooler that can be paired with a great number of processors, including the Ryzen 5 9600X. 

Unlike the DH-15 on our list, the AP1-V comes with a single 120mm fan. However, it has a max speed of up to 1,800 RPM, which is pretty decent and should help keep the processor cool at all times. It is compatible with both AM4 and AM5 sockets, and you can even use it with multiple Intel CPUs.

The overall design of the APNX AP1-V is also pretty clean and minimalistic, and the fan is also ARGB. To test its performance, we placed it on the i5-14600K. The idle temp remained at 30°C for the most part, and it never went above 40°C. During the Aida stress test, the average temp was around 75°C, and it didn’t cross 94°C.

This is a fantastic bang for the buck cooler that is easy to install and does a decent job at keeping the 14600K cool. 

The only downside about the AP1-V is that its fan is integrated. This means that if something happens to the fan and it stops working, you will have to get a new cooler. Other than that, we couldn’t find anything wrong with it.

Overall, the APNX AP1-V is a great choice for the Ryzen 5 9600X if you’re tight on a budget. It will help keep the temps low if you’re using the right thermal paste with it. We also recommend getting one of the best Airflow cases and the best 140mm case fans, as these will also help with keeping the temps low.

What users say

According to Amazon reviews, the cooler looks stunning, and its performance is also pretty great. One of the reviewers said: "Keeps temps really low at idle at 28°C and low while gaming. For 49 dollars it is a great option, also very quiet."

How to pick the best cooler for this CPU

Choosing the right cooler isn't just about picking the one that comes with a premium price tag or has a large radiator. Instead, there are some factors that should be influencing your decision, and a few of them are mentioned below.

Compatibility

Make sure the cooler you are getting is compatible with your CPU. This is because some CPU coolers only work with either Intel or AMD. We recommend opting for one that works with both, as this way, you won't have to worry about replacing the cooler if you switch to Intel in the future.

Budget

Your budget will decide the cooler you can get. If you're not short on cash, then we'd definitely recommend opting for a high-end Air Cooler, like the Noctua NH-D15. Or, you can even push it even further and go with an AIO Cooler instead, as this is the best cooling solution. However, make sure the AIO Cooler you are getting can fit inside your PC, as not every case can accomodate a 360mm radiator.

But if you're tight on a budget, then you can find several Air Coolers for under $50, including the one from APNX that we mentioned in our list. These may not come with extra features, but their performance is still strong.

That said, great performance comes at the price of a high thermal output, and since the Ryzen 9000 series processors come unlocked for overclocking, this means a higher TDP and thermal output. This can lead to thermal throttling, which drops the CPU’s performance.  

So, having a robust cooling solution is crucial to optimal performance. However, we understand that selecting one option is difficult due to the sheer amount of options available. So, we took the liberty of researching for you to come up with a list of options. We then thoroughly tested those options in-house and put forth those with excellent performance. 

This should help you kick off your buying journey in the best possible manner and make an informed decision. If you’re interested in checking out other options, our cooling hub has plenty of CPU coolers that we’ve reviewed. If you’re looking for a complete overhaul, we’ve also got you covered with our selection of the best GPUs for Ryzen 7 9700X. On top of that, you can order a 9700X for your build right now and beat the scalpers.

How we picked

Our selections aren’t based on on-box specifications; instead, we take a hands-on approach and test the limits of each CPU cooler by running it against various benchmarking software like Aida64 and CPU-Z. You can learn more about how we test CPU coolers in-depth to get a better understanding of our selection and testing process. 

In addition, we look at the CPU cooler’s brand, price, dimensions, and installation process. As this component will remain the same for the next few years, it needs to be invested in wisely.

Our top picks

The Ryzen 9 9700X's next-gen performance deserves a CPU cooler that can handle that heat, and for that, we recommend the Noctua NH-D15. Noctua has been a big player in the cooling solution industry for a long time, and its iconic brown color can’t be mistaken, whether you love it or hate it. 

During our testing for the Noctua NH-D15’s review, we were surprised yet pleased to see that it has excellent cooling performance for an air cooler. This is courtesy of its twin-fan design, which makes it bulky but gets the job done. 

It has dual 140mm fans with a max fan speed of 1500 RPM. While that RPM might seem slow compared to other options, these fans don’t need to spin as fast as 120mm to get the same cooling effect. 

Moreover, it has dual aluminum heatsinks to accompany the fans and six vapor chambers connected directly to the CPU contact plate. This ensures that all the heat generated from the processors is efficiently transferred to the heatsinks and expelled using the powerful 140mm fans.

The NH-D15 from Noctua is a fantastic cooler with a brilliant value for money, it is capable of cooling many CPUs in the higher end thanks to it’s double stack heatsink and dual 140mm fans.

Our testing rig has an Intel Core i5-14600K installed with an RTX 4070 Ti Super. For reference, this processor has a base and maximum power of 125W and 181W, respectively, while the 9700X has a humble TDP of 65W. This brings the difference to around 60W and 116W, which is massive. 

So, before we started the Aida stress test, which takes your CPU to its utmost limit, we checked for its idle temperature, which came around 33°C - 34°C. During the stress testing, the CPU core and max temp we recorded were 70°C and 86°C, respectively, which is a considerable jump from the idle temp, but still had plenty of room to go before reaching the upper limit of 100°C. 

The CPU has 0% thermal throttling. To show you how effective this CPU cooler was, we recorded the air temperature behind the fans before and during the stress test. The idle air temperature was 27.5°C, while during the stress test, it was 30.2°C. 

Overall, the Noctua NH-D15 is an excellent CPU cooler for the Ryzen 7 9700X, given its cooling performance, simplicity, and price point. It also comes with pre-applied high-quality thermal paste, but if you want to ensure the best performance, we recommend using the best thermal paste.

What user say

According to Amazon reviews, this air cooler has excellent performance and quiet operation, which is very liked by users. One reviewer said: “I've always heard great things about Noctua NH-D15s, and now that I can finally experience one, those claims are all accurate. The Noctua NH-D15 is great for users who want a quiet and cool air cooler.”

A CPU cooler doesn’t have to be bland while doing its job, and this is where the ASUS ROG Ryuo III 240 comes in. Not only did it have top-notch performance in its review, but it also has good features that bring any build to life. 

To begin with, this AIO cooler has dual 120mm fans with a whopping max fan speed of 2,200 RPM. This fan speed is one of the fastest we’ve seen, and looking back, it isn’t surprising that it performed so well during our hands-on testing. 

It is very similar to Ryujin, with some distinct changes like the CPU block being rounded instead of having corners, which gives it a different look. That said, it also has the Anime Matrix LED on the CPU block, which should allow you to run different gifs or custom animations to add a bit of your personality to your build. 

An important aspect of any AIO cooler is the tubes because if they are too stiff or aren’t properly covered, they can get damaged and start to leak, which spells the end. That said, the tubes for this cooler were braided and had the perfect balance between robust and flexible, meaning you should be able to install this CPU cooler in different orientations with ease, especially due to its swiveling 90° bend on the pump block. 

The ASUS Ryuo is a fantastic cooler for the money and is capable of cooling far beyond the CPU we tested it on.

As for its performance, we used the 14600K as our test subject again and checked for the idle temperature before ramping things up to the extreme. The idle CPU core temperature came to around 29°C, with the max temp coming to around 31°C. The air temperature behind the fan was 25.9°C.

During the Aida stress testing, the CPU core and maximum temperature came around 61°C and 77°C, respectively, with the air temperature being 30.6°C. There was 0% throttling, and these temperature levels are more than normal for any CPU, especially the modern ones with a higher performance threshold. 

So this should also give you enough overhead to overclock your CPU without running into overheating issues. That said, if your processor is already hot and you’re wondering how to lower the CPU temperature, we’ve got you covered. 

Overall, the ASUS ROG Ryuo III is a solid AIO cooler with excellent cooling performance and features. ASUS is a brand synonymous with incredible hardware, and this cooler continues that legacy. 

What users say

According to Amazon reviews, this is an incredible AIO cooler with great cooling performance, aesthetics, and customizability due to the Anime Matrix LED. One reviewer said: “This is a great AIO cooler. I have this on an unlocked 12th gen i9 processor running at a solid 5.2 GHz no issues. Swapped thermal paste for Noctua non-conductive. Fans are really quiet, pump is basically inaudible compared to the fans even running consistently at 100%.”

If you're operating on a budget but want a CPU cooler that can handle the Ryzen 7 9700X, check out the APNX AP1-V. This pocket-friendly cooler had decent performance when we tested it for our APNX AP1-V review.

For starters, this CPU cooler is compatible with the AM5 socket, meaning you can easily mount it on top of the Ryzen 7 9700X. It also has a 120mm fan, which has a maximum speed of 1,800 RPM and a noise level of 16.1 - 32.8 dBA. This is pretty quiet, as a whisper is generally said to have a noise level of 30 dB(A). So, you shouldn't be bothered by the noise output during working or gaming.

The AP1 has a clean and sleek design with an RGB fan, but it is integrated inside the cooler as opposed to being mounted outside on the heatsink, as we saw in our Noctua NH-D15 review. This means that if this CPU cooler is to ever malfunction, you'll have to get a new one as the fan can't be replaced. However, seeing its cost, it might not be a big issue.

This is a fantastic bang for the buck cooler that is easy to install and does a decent job at keeping the 14600K cool. There’s not a lot of thermal headroom available to upgrade CPUs, however, so that is something to consider. Overall, for the price, this cooler does well.

To check its performance, we mounted it on top of the 14600K with a base and maximum power of 125W and 181W, respectively. Before stress testing this CPU, we checked the idle CPU temperature, which was 40°C. However, when we stand the Aida stress test, the temperature peaked at 94°C and even then there was 0% throttling.

So, while 94°C might not be acceptable for a lot of people, it kept it below its maximum operating temperature and didn't let it thermal throttle. However, our test bench is open so the results might be better with a proper airflow. That being said, the 9700X has a maximum TDP of 105W, which is lower than the base TDP of the 14600K.

So, we can expect this CPU cooler to perform better with that, as the Ryzen 9000 CPUs are energy efficient. To get the best performance, we also recommend using the best thermal paste to ensure efficient heat transfer from the CPU to the CPU cooler.

What users say

According to Amazon reviews, this cooler has good performance, but some have complained about its noise. One reviewer said: "Great Air Cooler, love the matte white color that goes perfect with my Asus TUF Build, with an intel I5 14600KF and Gigabyte AUROS z790 Ice X white motherboard. Keeps temps really low at idle at 28 c and low while gaming. For 49 dollars it is a great option, also very quiet."

If you want the best of the best and aren’t concerned about how much it costs, we recommend giving the Corsair H150i Elite LCD XT a shot. In the Corsair H140i Elite review, it performed stellarly, and we went easy on it as we used the 14700K to test this cooler instead of the 14600K. 

This CPU cooler has three ML120 fans with a max speed of 2000 RPM. On top of that, it is compatible with a handful of sockets ranging from LGA 2066 and sTR4 to AM3, AM4, and AM5. So, if you were using it in your previous Intel build, you can rest easy knowing that it’ll be just as easy to install in your 9700X build with the AM5 socket. 

A neat and fancy feature of this cooler is its 2.1-inch LCD on the pump block, which allows you to display vital CPU information such as temperature, RPM, and more. However, if you care about that and want the latest meme you found funny displayed, that too is possible. 

Besides the customizability, the design is also innovative, as the display and pump block are two separate entities. What this means is that you can easily install the pump block and then attach the LCD on top of it; this should help you work faster as you won’t have to worry about damaging the screen. 

On top of that, the ML120 fans use magnetic levitation technology, meaning their operation should be very quiet and have a long lifespan due to the lack of wear and tear that other fans experience. If that wasn’t enough, the CPU block has a swivel that allows the sleeved rubber tubes to be attached to it in different orientations, giving you the freedom to play around with your build. Just by looking at these features, we aren’t surprised that this is considered one of the best CPU coolers out there.

Regarding its performance, as mentioned at the start, we swapped out the 14600K with the 14700K, which has a maximum turbo power of 253W, while the 9700X has a 65W TDP, a difference of 188W.

The Corsair H150i ELITE LCD XT is one of the best CPU coolers on the market right now, despite being a little older. It provides ample cooling performance and pairs that with age related savings.

We ran tests for its full fan and balanced mode. The maximum CPU temperature with full fans and balanced settings was 29°C and 30°C, respectively, while the air temperature behind the fans was 25.4°C(1647 RPM) and 24.6°C(734 RPM). 

When we started the 5-minute Aida stress test, the average core temperature for both settings came around 79°C and 84°C, while the maximum temperature for both was 100°C. There was 12% and 17% throttle for full fan and balanced mode, but that isn’t surprising since it was operating at its maximum thermal limit. 

This result definitely looks alarming, but we need to understand the nature of this test. The Aida stress test pushes the CPU to its extreme limits, something everyday usage can’t do. You can run three instances of Crysis 3, and it won’t hit this temperature. 

That said, we also tested its performance during gaming and chose Days Gone as the final hurdle. During the 10-minute gameplay, it had a maximum CPU temperature of 71°C, which is very normal for gaming, and some may even consider it on the lower end. 

Overall, the Corsair H150i Elite LCD XT is a solid option if you’re looking for a triple-fan AIO cooler, and its performance speaks for itself. 

What users say

According to Amazon reviews, this CPU cooler has great performance, the customizability is simple and easy, and its huge so be sure to check whether your casing can accommodate it or not. One reviewer said: “Results may vary (everyone's case cooling is different), but with an overclocked Intel I7, 13700k I am running near ambient room temperature at idle (27-30C) and under Prime 95 (pretty much the hardest stress test you can give a CPU around 86C after 15-20 minutes. Those temperatures, to keep it simple, are VERY good temperatures to see on a chip that is know to run on the hotter side of things even without an overclock.”

How to select the best CPU cooler for 9700X

The processor is an integral part of any system, but its performance degrades if it gets too hot. That said, it needs to be cooled down, but spending top dollar on a fancy cooler isn’t a solution for everyone. There are some factors you must consider before purchasing so you don’t overspend or underspend, which could affect the CPU’s performance. We’ve listed some of these factors below:

Compatibility

The first thing you need to check is socket and casing compatibility. As AMD confirmed, CPU coolers that work with AM4 generally also work with AM5, but it's always better to be safe than sorry and verify whether a specific cooler will work with your selected option. 

Case compatibility could make or break your setup. If you get a big cooler that can’t fit inside your casing, you’ll have to return it and get a smaller one. For example, if you have an ITX casing that can only fit a 240mm AIO radiator, getting a 360mm would make no sense. The same is true for air coolers, as they can also be huge, which can stop the side panel from closing.

So, measure the dimensions of your casing and see whether the CPU cooler you want to purchase will fit easily inside.  

Noise levels

The next factor you need to consider is the CPU's noise level. You can do this by checking out our reviews or reading up on customer feedback on Amazon or Reddit. The level of noise the cooler creates depends on its type. Coolers with smaller fans and a lower RPM tend to make more noise as they have to spin faster, while bigger fans and AIO coolers are generally much quieter.

In the end, it all comes down to personal preference and how much noise you’re comfortable with. One more thing: the noise level also fluctuates depending on the workload, so if you’re crunching heavy numbers, the CPU will work hard, creating more heat, and the CPU cooler will spin faster to dissipate that heat, creating more noise. 

Budget

Your budget is the most crucial factor when considering which CPU cooler to purchase. There are plenty of options available in the market with fancy features like an LCD on the pump block or ARGB lighting, but they cost more, and honestly, these features don’t affect the cooler's performance. 

So, we recommend operating within your budget, filtering your options based on that, and selecting a cooler, whether an AIO or an air cooler, that offers the best balance between performance and value.

As you know, higher performing CPUs can create a lot of heat, especially when under constant heavy load. And to make sure the processor stays cool, you’ll need to pair it with the right cooler.

The 9900X has a default TDP of 120W, and without proper heat dissipation, you could run into thermal throttling issues. On top of that, too much heat can also damage the CPU in the long run.

We've reviewed loads of CPU coolers here at PC Guide, and we put them through rigorous testing in the process. We've gone ahead and selected which CPU coolers we think are the best for the upcoming processor, to give you a hand with your search. And if you're looking for more hardware options, be sure to check out our best GPU picks for the 9 9900X if you're planning on a more major upgrade.

How we picked

We never solely rely on online ratings and reviews while selecting the products for our guides. Instead, we take a hands-on approach and test the coolers ourselves to understand their real-life performance. Feel free to take a closer look at our hand-on testing processes to see for yourself.

When selecting a CPU cooler, we consider factors such as price, compatibility, performance, and installation. After all, we don’t want you to waste your money on the wrong cooler, one that can’t even keep the idle temperature low.

Our top picks

As the Ryzen 9 9900X is one of the most powerful CPUs in the AMD 9000 series, you’d want nothing but the best for it. And for this, we recommend the ASUS ROG Ryuo III 240 ARGB. While this may be an expensive option, it is perfect for those who are looking for the ultimate performance. In our ASUS ROG Ryuo III 240 review, we found it to be an excellent cooler that didn’t let the temperatures go above safe levels. 

To begin with, the ASUS ROG Ryuo III 240 has a max fan speed of 2,220 RPM, which should help keep the processor cool under load. The fans are also lightweight and very quiet, so you won’t run into any noise-related issues. On top of that, the CPU block comes equipped with an 8th Gen Asetek pump, and there’s also a fully copper heat exchange plate below it, which helps efficiently transfer the heat from the processor to the CPU cooler. 

The ASUS Ryuo is a fantastic cooler for the money and is capable of cooling far beyond the CPU we tested it on.

Installing the cooler is also a pretty simple task, and ASUS includes an installation guide in the box to help you out with that. However, while it comes with pre-installed thermal paste, we’d highly recommend choosing one of the best thermal pastes for better cooling. Otherwise, you may run into overheating issues. If you do, you can check out our guide on how to stop your CPU from overheating.

As far as the performance is concerned, we tested the Ryuo III 240 with the Core i5-14600K. When the CPU was not doing anything intense, the temperature stayed around 29°C, and the max we noted was 31°C. When we decided to put the CPU under stress, the average temperature was around 64°C, and it never went above 77°C. The highest we saw was in the Aida stress test, which is one of the most intensive CPU applications out there.

Overall, the ASUS ROG Ryuo III 240 is a cooler worth pairing with a high-end processor like this one. It managed to keep the temperatures within safe limits during every test, so you should face no problems during intense gaming sessions. There’s also a mini LED on the cooler that can display the core system stats and customize animations. 

What users say

According to the reviews on Amazon, the ASUS ROG Ryuo III 240 is an excellent choice for high-end processors. One of the reviewers praised its performance and said: "This AIO is superb. A little pricy but still a good chunk cheaper than the Strix cooler with the HD screen. Holds steady temps. Keeps my CPU right around 42C-45C when playing RDR2 at ultra settings. Highly recommend."

If you want a cooler for the Ryzen 9 9900X that will not only help keep the temperatures low but also improve the overall aesthetics of your build with custom RGB lighting, then you’d want to check out the Corsair H150i ELITE LCD XT. This is one of the largest AIO coolers available in the market, and in our Corsair H150i ELITE LCD XT review, we found it to be a perfect choice for high-end processors.

To begin with, its design is similar to most of the AIO coolers out there, so there’s nothing special about it. However, its build quality is pretty strong, as it's made from high-quality materials. On the CPU block, there is a 2.1-inch IPS screen, which is perfect for those who want to see real-time stats about the current state of their CPU. But if that’s not a concern for you, then you can ditch that and run some cool custom animations on it instead.

The cooler comes equipped with three ML120 ELITE fans, which offer speeds of up to 2,000 RPM. On top of that, they offer mangentic levitation bearings and air glide technology, and both will help with keeping the fans quiet and smooth. 

The fans also offer 24 individually addressable RGB LEDs, and you can also find an RBG ring around the CPU block. These can be controlled using the Corsair iCUE software, which allows you to create custom lighting profiles and synchronize your lighting with other Corsair devices.

The Corsair H150i ELITE LCD XT is one of the best CPU coolers on the market right now, despite being a little older.

To learn about its performance, we decided to test the Corsair H150i ELITE LCD XT against the Intel i7-14700K. We checked the idle temperature in both ‘Full Fan’ and ‘Balanced’ profiles, and it didn’t go above 30°C. We then decided to push the CPU to its limit by testing it in Aida64.

During a 5-minute test, the average temp was around 79°C in Full Fan mode, and it went up to 84°C in the balanced mode. The max temp that we recorded was 100°C. However, while this may sound alarming, it is important to note that Aida is the extreme end of CPU testing, and you will rarely push your CPU to the limits it will. When we tested the cooler in gaming, the average temp was around 55°C, and the max it hit was 71°C in Days Gone. So, there’s nothing to worry about.

Overall, the Corsair H150i ELITE LCD XT is a stunning cooler that will help keep your CPU cool without breaking a sweat. After all, it is one of the best AIO coolers available in the market.

What users say

On Amazon, most reviewers only have good things to say about the H150i Elite. One of them mentioned: "Highly customizable, aesthetically it looks great. It's a decent cooling solution for my 14900K. Idles at around 33C and 60-68C while gaming."

If you’re not a fan of AIO Coolers or are looking for an affordable option, then we’d recommend the Noctua NH-D15. This cooler features two 140mm fans, and in our Noctua NH-D15 review, we found it to be one of the best Air Coolers on the market. 

To begin with, the NH-D15 offers a dual fan setup with two heatsink stacks, which come with six copper and aluminum vapor chambers. While this does make it bigger in size, it also makes it perform better than other Air Coolers out there. On top of that, both fans have a max speed of up to 1,500 rpm. While this may not be as fast as the AIO Coolers on our list, it is still enough to keep processors cool under load. 

You also don’t have to worry about running into any noise-related issues, as the Noctua NH-D15 has a noise level of 24.6 dBA. For reference, a whisper is generally between 20–30 decibels.

The NH-D15 from Noctua is a fantastic cooler with a brilliant value for money, it is capable of cooling many CPUs in the higher end thanks to it’s double stack heatsink and dual 140mm fans. 

To check its performance, we placed it on the Core i5-14600K and started the Aida stress test. The average temp was 70°C, while the max recorded temp was 86°C. Again, while this isn’t as good as an AIO cooler, it is still pretty impressive for an Air Cooler. In Blender, which isn’t as intense as Aida, the max temp stayed around 72°C.

Overall, the Noctua NH-D15 is definitely a great Air Cooler for the this new Ryzen processor. It can help keep the CPU cool, even during long gaming sessions. We also recommend using one of the best airflow cases and the best 140mm case fans for better cooling. However, keep in mind that the cooler only comes in two colors: creamy brown and black. 

What users say

According to the reviews on Amazon, the NH-D15 is capable of keeping the temps low, even when paired with high-end processors. One of the reviewers said: "I've always heard great things about Noctua NH-D15s, and now that I can finally experience one, those claims are all accurate. The Noctua NH-D15 is great for users who want a quiet and cool air cooler."

If you don't have a big budget for a high-end CPU cooler and want something that is affordable yet can help keep the processor cool, then you may want to check out the APNX AP1-V. This cooler provides great value for money and can help keep the temps low. In our APNX AP1-V review, it delivered a great performance in several tests.

To begin with, the design of the AP1-V is different from the DH15 as it features a single fan. However, this 120mm fan can operate at a speed of 1,800 RPM. The single-fan design also helps with keeping the overall look of the cooler clean and minimalistic.

The best part is that the AP1-V is compatible with both AM4 and AM5 sockets. On top of that, it works with Intel processors as well. So, if you decided to make a switch to Team Blue in the future, you won't have to worry about replacing the cooler.

The APNX AP1-V is a great option for those who want something that offers a great blend of performance and affordability.

Now, let's get down to the most important part: the performance. We placed the AP1-V on the Intel i5-14600K. The ideal CPU temperatures were around 30°C, and we never saw them go above 40°C. This is pretty impressive for a cooler that falls in the budget category.

Next, we decided to test the cooler in one of the most intense stress tests, Aida64. We were expecting the temperatures to be around 99-100°C. However, to our surprise, the average temperature was around 75°C, while the max it reached was 94°C. Even in Blender, the average temperature was the same, while the max recorded temperature was 86°C. Considering these stress tests push the CPU to the extreme limit, you can expect the temperatures to be lower in gaming and other productivity tasks.

Overall, the APNX AP1-V is a great budget option for the Ryzen 9 9900X. Its performance may not be as good as the other options on our list, but it also does not come with a premium price tag.

What users say

Users on Amazon are satisfied with the performance of the APNX AP1-V. One of them said: “Keeps temps really low at idle at 28°C and low while gaming. For 49 dollars it is a great option, also very quiet.”

How to select the best cooler for this processor

Selecting the best cooler isn't just about picking up the most expensive option available. Instead, there are some factors that you should consider before making a final purchase, which are mentioned below.

Budget

Your budget will play the biggest role in the selection process. Since you’re using a Ryzen 9 9900X, chances are that budget isn’t an issue for you. If that’s the case, then you should definitely opt for a high-end AIO Cooler, as this will be the perfect choice for a processor like the 9900X. 

But if you’re not willing to overspend on the cooler or are short on cash, then there’s no harm in choosing an Air Cooler. Just make sure that the one you’re going with has a decent fan speed and can keep the temps within the safe levels. 

Compatibility 

Make sure the cooler you’re getting is compatible with your CPU and casing. Some coolers only work with a specific brand, so you want to choose the one that either supports the 9 9900X or works fine with both Intel and AMD CPUs.

If you’re opting for an AIO Cooler, make sure your case is big enough to accommodate it. This is because a 360mm AIO cooler is pretty large in size, and it won’t fit inside every case. So, make sure to check this before getting the cooler, as you don’t want to end up getting a 360mm AIO cooler while your casing only supports a 240mm radiator.

The more powerful processors get, the more energy they require to run, meaning their thermal output is also great. This is fine, as they are designed to run that way, but too much heat could damage the CPU or result in thermal throttling. The Ryzen 9000 series flagship CPU, 9950X, has amazing specifications and a TDP of 170W to match. 

So, it wouldn’t be surprising if it got a bit hot during operation, and robust cooling solutions must be used to prevent overheating. That said, selecting one CPU cooler is easier said than done, as hundreds of options are available with varying styles and features. 

To help you cut through the clutter, we researched the market and put together this in-depth guide that lists multiple cooler options, their reviews, details, and pros and cons. So, let’s get right to it, shall we? If you want to order a Ryzen 9 9950X before the scalpers clear out the shelves, we've got you back.

How we picked

Our selections aren’t based on on-box specifications; instead, we take a hands-on approach and test the limits of each CPU cooler by running it against various benchmarking software like Aida64 and CPU-Z. You can learn more about how we test CPU coolers in-depth and visit our cooling hub for more cooler buying guides. 

In addition, we look at the CPU cooler’s brand, price, dimensions, and installation process. As this component will remain the same for the next few years, it needs to be invested in wisely.

Our top picks

The Ryzen 9 9950X is the most powerful CPU in the 9000 series lineup, and to keep this monster cool, we recommend the ASUS ROG Ryujin III 240. We tested this CPU cooler for its review, and even though it has 120mm fans, its performance didn’t disappoint.  

For starters, this cooler has a max fan speed of 2,000 RPM and comes with pre-applied high-grade thermal paste. It also features a copper CPU plate for effective heat transfer and a 3600 RPM Asetek pump that should keep the liquid pumping at a good rate to ensure low temperatures. However, if your CPU is overheating and you're wondering how to stop it from overheating, we've got you covered there as well.

It has an all-black finish, including the aluminum radiator, making it an excellent choice for various builds, whether there is a lot of RGB or a completely silent build. The one thing that stands out is the 3.5” LCD on the pump block, which allows you to display different memes, gifs, or animations. While this doesn’t affect how the cooler performs, it does help add a bit of your personality to your build, which is a nice addition. 

There is no point in purchasing an AIO cooler with poorly constructed pipes as they carry the heat to the radiator, and the fans expel the hot air. So, if the tubes leak or are prone to damage, you’re throwing your money away. That said, the Ryujin III’s tubes are made from sleeved rubber and have a 40cm length. 

It manages to keep our 14600K cool in every scenario, which is the most important factor when it comes to CPU coolers. 

This should allow you to install this CPU cooler in a number of orientations according to how you’ve positioned other components. This CPU cooler is also easy to install and is compatible with both Intel and AMD, meaning you just have to use their respective backplates. In this case, you’ll use the AMD plate, which will fit comfortably on top of your 9950X. 

We checked its performance against the i5-14600K, which, according to Intel, has a max turbo power of 181W, 11W higher than the 9950X. We conducted several tests, but we’ll look at the results of Aida, which pushes the CPU under inhumane stress to a point where everyday workload can’t possibly take it. 

The ASUS ROG Ryujin III kept the 14600K in a pretty comfortable range with an average core temperature of 61°C and a max temperature of 77°C. 

So, this cooler should be able to handle the thermal output of the 9950X and keep it performing optimally. However, we recommend using the best thermal paste to ensure effective heat transfer from the CPU to the cooler contact patch. 

What users say

According to Amazon reviews, the Ryujin III 240 has great value, performance, and build quality. One reviewer said: “I've been looking for something to tame the beast of the i9 14900k, so I decided on this. I got the noctua two fan, and it's definitely keeping my temps down. At high load and gaming, I get about 50-65c.” We believe this review sums up perfectly what this CPU cooler is capable of. 

AIO coolers can be expensive due to the design, technology, and performance they offer. That said, many still use air coolers, which are a viable option, especially Noctua, a name synonymous with excellent cooling performance. 

We recommend using the Noctua NH-D15 CPU cooler for the 9950X as it costs less than AIO options. During its review, it had excellent performance keeping our test bench’s CPU cool.  

To begin with, this cooler has a max fan speed of 1,500 RPM, and while that may seem slow, it has two 140mm fans, which don’t need to spin as fast as 120mm fans but achieve the same cooling results with a lower RPM. 

It also had a noise level of 24.6 dBA, which, to put it into perspective, is like whispering. This CPU cooler is also compatible with the AM5 and AM4 platforms, so you don’t need to worry about compatibility issues. 

The NH-D15 from Noctua is a fantastic cooler with a brilliant value for money, it is capable of cooling many CPUs in the higher end thanks to it’s double stack heatsink and dual 140mm fans.

To accommodate the dual fans, it also has dual aluminum heatsinks, which have six copper and aluminum vapor chambers going through them for effective heat transfer. There is a bit of a design flaw, as you have to be careful while installing the fans on the heatsink because they are sharp, and you could accidentally get cut.

Regarding its performance, we installed it on top of the 14600K and started the Aida stress test. The 14600K under extreme load had an average core and max temperatures of 70°C and 86°C, respectively, with 0% throttling. The air expelled from the fans had a temperature of 30.2°C, showcasing how effective this CPU cooler is. 

Overall, the Noctua NH-D15 is a solid air cooler with excellent performance and should be able to keep even the most demanding processors cool. 

What users say

According to Amazon reviews, this cooler has excellent performance and quiet operation, making it well-liked among the users. One reviewer stated: “Performance is exceptional. My thermals have never been this low or consistent. For reference, I have been using an AIO with a single fan radiator, so I was due for an upgrade. I run a Ryzen 5800x3D, and I haven't seen my temps go higher than 80 degrees, even during my full load stress test.”

If you're not limited by your budget, we've brought in another ASUS AIO cooler for you, the ProArt LC 420. This is one of the largest CPU coolers we’ve seen, and during its review, it performed stellarly, which didn’t come as a surprise. 

This CPU has a max fan speed of 2,000 RPM and features three Noctua NF-A14 Industrial PPC-2000 140mm fans, which help it tame even the wildest processors. Its tubes are made of sleeved rubber like we saw in our top pick, which gives it a layer of durability and ensures smooth operation for a long time. To keep the rest of your components as cool as your CPU, we recommend using powerful 140mm case fans to ensure adequate cross ventilation.

This CPU cooler doesn’t have fancy features like an LCD on the pump block or ARGB fans; instead, it focuses purely on performance and delivers in that domain. We have the same test bench to check all our CPU coolers, which gives us a clear picture of how they compete against each other. 

This cooler is designed to be the best, and integrate seamlessly into any PC case that can accommodate is huge 420mm radiator. 

The idle temperature of the 14600K went to a maximum of 33°C, and the air temperature behind the fans was 27.8°C. During the Aida stress test, the maximum temperature was 72°C, and the average core temperature hovered at 57°C. The air temperature behind the fans at this point was 30.8°C, a difference of only 3°C, which is massively impressive. Even the max temperature isn’t that high, as processors can easily cross 80°C during heavy loads, though the ambient temperature plays a big role. 

For example, if you’re located in a hot region, the CPU's idle temperature will automatically be higher than if you were in a cold region. So, the maximum and average temperatures will also be relatively high. If you're in this situation, the best airflow PC case could also help keep the temperature low due to better ventilation.

Overall, this beast of a CPU cooler is everything you’d need to keep powerhouses like the 9950X cool and provides a good overhead for overclocking. For an unrivaled gaming experience, we recommend using the best GPU for Ryzen 9 9950X.

The Ryzen 9 9950X comes with a price tag of $649, which is comparatively cheaper than the previous generation processor but still is a big amount. So, if you're operating on limited finances after purchasing the 9950X, the APNX AP1-V CPU cooler might be what you're looking for. During our testing for this cooler's review, it had great performance, especially when you consider how less it costs.

For starters, this air cooler has a 120mm fan with a maximum RPM of 1,800. This is normal for 120mm fans as they need to spin faster to expel the heat carried to the heatsink from the CPU. A great aspect of this cooler is that it comes with AM4, AM5, and LGA1700 mounting brackets, so regardless of whether you're with Team Blue or Red, this cooler will accommodate your CPU.

The AP1 has a very sleek, minimalistic design that doesn't stand out but should complement the overall aesthetic of your PC. For all those who have suffered from cuts during fan installation from sharp heatsinks, this next part is going to be a breath of fresh air. The fan comes integrated, meaning you don't have to secure it to the heatsink. So, you can simply take it out of the box, apply the best thermal paste on your CPU, and screw the CPU cooler in place.

This is a fantastic bang for the buck cooler that is easy to install and does a decent job at keeping the 14600K cool.

Inside the heatsinks, there are eight 6x5mm heat pipes that do a good job of carrying the heat away from the CPU, and this cooler is rated at 245W TDP despite its humble design and price tag.

Regarding its performance, we again took to the 14600K as it has a base and maximum TDP of 125 and 181W, respectively, which is 11W more than 9950X's 170W TDP. Before we started the stress test, the maximum CPU temperature was 40°C. After we started the stress test, which pushed the limit of the CPU, something that normal usage can't accomplish, the maximum temperature was recorded at 94°C, and the average core temperature came around 75°C with 0% throttling.

The Intel 13th and 14th-generation processors are famous for running very hot, and even then, this CPU kept the 14600K from throttling, and while 94°C is pretty high, it didn't reach its maximum operational temperature, which is great.

What users say

According to Amazon reviews, this CPU cooler is great for its price point and keeps the processors cool without making much noise. One reviewer said: "Great Air Cooler, love the matte white color that goes perfect with my Asus TUF Build, with an intel I5 14600KF and Gigabyte AUROS z790 Ice X white motherboard. Keeps temps really low at idle at 28 c and low while gaming. For 49 dollars it is a great option, also very quiet."

How to select the best CPU cooler for 9950X

The 9950X is a powerful processor, which means that its thermal output is great. So, it needs a robust cooling solution, but spending top dollar on a fancy cooler isn’t a solution for everyone. There are some factors you must consider before purchasing so you don’t overspend or underspend, which could affect the CPU’s performance. We’ve listed some of these factors below:

Compatibility

First, you need to check whether the CPU cooler you’re opting for is compatible with the CPU and casing. If you opt for an AIO cooler, ensure its radiator can fit inside your casing, or you won’t be able to install it. For example, you get a 360mm AIO cooler but your casing can only house a 240mm radiator at max. So, you’ll have to purchase a bigger casing or return the cooler for a smaller version, if available. 

Besides that, consider your CPU's socket type before purchasing a cooler. For the most part, all coolers come with different backplates for Intel and AMD, but it's better to be safe than sorry because you don’t want to find out that you spent a good amount of money on an LGA 1700 compatible cooler while you’ve got the 9950X on your hands, an AM5 processor. That said, CPU coolers compatible with AM4 motherboards also work with AM5 motherboards.

Noise levels

Some people are okay with the CPU cooler making a noise, while others don’t want it to make a peep. So, read the reviews and customer feedback of any cooler you’re looking at, as they’ll give you an idea about the acoustics. 

Budget

The budget is the most important factor when purchasing any component. It is always recommended to operate within your budget because if you spend more than your budget allows, you’ll have to compensate for that by lowering your daily expense amount or compromising the quality of other components. 

That said, for a processor like the 9950X, a high-end CPU cooler is the best option. It will set you back a couple of hundred dollars, but this isn’t something you change after a couple of months. So, think of it as an investment that can be transferred from build to build, serving you for years.

The Ryzen 7 X3D, with its advanced 3D V-Cache technology, is a powerhouse that demands efficient heat dissipation to prevent thermal throttling and maintain peak efficiency. Because of this, it's the best choice for games on the AM4 platform who want to save money.

If you're looking to secure this CPU for yourself, then you're going to want a CPU cooler to fully support it. There is a mix of both budget and not-so-budget-friendly performance options that would be a perfect pair with this particular CPU. Let's jump right in.

How we picked the best CPU cooler for 5800X3D

Our selection process for the best CPU cooler for the 5800X3D involves a meticulous review, where we evaluate the effectiveness cooler in a multitude of different scenarios. In essence, we test the CPU coolers to see how cool they keep the CPU. We try to include all kinds of workloads to encompass the wider use of the chips.

Build quality and design are also critical in our evaluation. We consider the materials' durability, the cooling mechanism's reliability, and the manufacturer's reputation for quality. User experience factors such as installation process, noise levels, and additional features like RGB lighting or software integration are also taken into account.

If you need more information on how we test and choose our CPU coolers, we have an article available to you for your viewing pleasure.

The ASUS Ryujin III 240 is one of the best 240mm coolers on the market today, being the third iteration of the Ryujin, all of the kinks and hiccups have been ironed out, shaping a truly capable cooler. This cooler is especially effective at cooling the 5800X3D and then some, we know this because we reviewed this cooler using the 14600K as the benchmark CPU, and it cooled that CPU with no problem.

It's worth mentioning, that the 14600K has a much higher TDP than the 5800X3D, (125W vs 105W). This doesn't seem like a lot, but it can really make a difference, regardless, the Ryujin III didn't struggle with the 14600K and it certainly won't struggle now. This cooler is made with only the most high quality of components, and thermally efficient materials. Including the new 8th-generation Asetek pump.

It’s hard to find a 240mm AIO that keeps the 14600K as cool as this cooler does, the performance is so good in fact that you would be forgiven for thinking that this was a 360mm

If you want a CPU cooler with an LCD screen that can display system health information, then the Ryujin just might be the CPU cooler for you. With that being said, you aren't limited to just system information on this full-color LCD. You can display a funny image, GIF, or something to spice up your PC build further.

The industrial aesthetic that the Ryujin brings makes it fit into almost any build without looking out of place, especially if you have some of the more bulky high-end components inside your system.

What users say

The Ryujin III has a rating on Amazon of 4.6 out of 106 reviews, with one verified purchaser stating "Keeps 14900k pretty cool" This speaks for itself really, doesn't it?

The Noctua NH-D15, which we recently reviewed, is one of the best air-based coolers on the market. Whilst air coolers are generally less efficient at cooling than their AIO counterparts, they offer an affordable option and option that will pair nicely with the 5800X3D. The D15 features a dual fan setup with two main heatsink stacks, offering double the surface area and cooling potential of most air coolers on the market.

The Noctua cooler we’re testing today is certainly capable of keeping thermal throttling at bay, but the temperatures aren’t exactly AIO level, of course, that makes sense, given the fact this CPU cooler isn’t an AIO

With this Noctua cooler, you get the basic foundation of a CPU cooler, there's no fancy screens to be had here, it's a bare-bones cooler but cooling is something It does very well. Driving almost all of the cooling process are the Noctua NF-A15 140mm fans, which can move air in volumes at a lightning-fast pace.

What users say

The Noctua NH-D15 has a 4.7 rating out of 5 on Amazon, based on 11,807 reviews of the product, which if the sales alone are any testament to this cooler quality, says that this is a very widely revered product. One user went as far as to say "I replaced a 3-year-old AIO liquid loop with this and I just wish I’d done it sooner. It’s MUCH quieter and both my idle and stress temperatures have decreased by a good amount. It is definitely a chunky boy but it’s actually really straightforward to install".

The Corsair H150i LCD may seem like overkill for the 5800X3D specifically, but the cooler you keep your CPU, the longer it should last. So really, this is just an investment into the longevity of your hardware, and with this cooler rated to last around 6 years (as the warranty states) it's likely this AIO will see a couple of your CPU choices.

If you need a CPU cooler to titillate the need to plaster memes all over the inside of your PC, or you’re more sensible and want to display system information to keep better track of your PC, then this cooler might be the one for you

Maybe you want to go ahead and shoot for the 7000 series, or the upcoming 9000 series on your next CPU, this cooler will take you there. Corsair is well known for its quality and performance in the cooling space with years in the business of keeping PC components cool. This is reflected heavily in our Corsair H150i LCD review.

Not to mention, you have a 480 x 480 LCD screen to display real-time system information, fed to you by iCUE, Corsair's proprietary monitoring and control software. iCUE is relatively easy to use and handles all of the updates your cooler will need throughout its life. Yes updated, coolers need updates in 2025.

What users say

The Corsair h150i LCD has a 4.3 rating out of 1,033 reviews, another astonishing sales record. One user, in particular, had this to say about this Corsair CPU cooler: "This bad boy is like the superhero of CPU coolers - keeping your processor chill while looking cool with its LCD display".

Features and considerations

Here we outline some considerations that you should take when selecting a CPU cooler, it doesn't matter if the cooler is for the 5800X3D or any other CPU, these considerations remain mostly the same. Apart from the cooling demands of the CPU, that's about the only variable.

Efficiency and performance

When selecting a CPU cooler for a Ryzen 7 5800X3D, cooling efficiency is the top priority. The cooler must be capable of handling the processor's heat output, particularly under sustained loads like gaming or video editing. Look for coolers with a high TDP rating, which indicates their cooling capacity.

System compatibility

Another vital aspect is the cooler's compatibility with your system. Ensure that the cooler fits within your case and doesn’t obstruct other components, especially RAM slots. Noise level is also a consideration; a quieter cooler is preferable for a distraction-free environment.

To screen, or not to screen?

Do you want your CPU cooler to have a screen? You have that option now, we're living in the future and it's starting to show. Having an LCD screen on your PC is entirely your choice and doesn't really do anything to affect performance. Saying that there is some argument to be made that seeing your CPU temperatures constantly will help you take better care of it.

But, to be honest, most of us just end up putting cat pictures on the screen anyway.

Is the 5800X3D hard to cool?

Compared to more modern CPUs, not really. Even compared to the same generation of CPU, then why do we need a good cooler for it? Well, good question. Keeping the Ryzen 7 cool increases its longevity, as it does with any CPU. Not to mention the fact that the 3D V-cache inside the X3D is very sensitive to high temperatures. So it's in your and the CPUs best interest to keep that CPU on ice.

Is a 240mm radiator enough for 5800X3D?

A 240mm radiator is more than enough to cool the 5800X3D, but the same job can also be handled by a good air cooler, such as the Noctua NH-D15 that we recommend in this article. The fact of the matter is that the X3D does not generate that much heat with its 105W TDP, but it's better the cooler it is, thanks to the 3D Cache.

Believe it or not, the 7800X3D isn't that hard to cool, but it is very sensitive to high temperatures, thanks to the 3D cache contained within. This means we'll have to ensure the X3D stays as cool as possible through those demanding workloads.

How we picked the best cooler for Ryzen 7 7800X3D

Our team of experts benchmarks and tests these coolers in a multitude of workloads in the pursuit of finding the best CPU cooler. You can review our testing methodologies on our PC Guide labs page if you're at all interested in how we test our coolers.

We also consider coolers that offer a balance between effective heat dissipation, noise levels, and longevity. Preference is given to coolers with proven track records of handling CPUs with similar or higher TDPs, ensuring they can comfortably manage the thermal demands of the Ryzen 7 7800X3D.

As per our review, the Corsair H150i offers fantastic performance to those who are willing to foot the bill, but don't let the price of this cooler put you off too much. This is one of the best-performing coolers that Corsair has on offer right now and is more than capable of handling a 120W TDP CPU such as the 7800X3D. It'll even handle more if you wish to upgrade in the future.

If you need a CPU cooler to titillate the need to plaster memes all over the inside of your PC, or you’re more sensible and want to display system information to keep better track of your PC, then this cooler might be the one for you.

If you want a cooler that can display real-time information about the state of the CPU on its 480 x 480 LCD screen, then this cooler might be the right one for you. But the functionality of the screen doesn't end there, you can put any image or GIF on the screen that you desire, making it a truly customizable piece of hardware.

The Corsair AF120 RGB ELITE PWM fans also deliver massive low-noise airflow with AirGuide technology along a high-surface area 360mm radiator for extreme CPU cooling performance. The fans alone cost roughly half of the value of the entire setup so that alone should be an indication of how valued they are.

What users say

The Corsair H150i LCD has a 4.3 rating out of 1,033 reviews. One user, said "This thing keeps my CPU cooler than a polar bear's toenails. Seriously, I could probably fry an egg on my processor without this bad boy. So if you want a CPU cooler that's as efficient as it is stylish, look no further than the Corsair iCUE H100i ELITE LCD XT"

This double-stack monster of an air cooler comes to us from the boffins at Noctua. This is the air cooler that means business and actually performs more like a 120mm AIO cooler. The reason behind this is the dual tower heatsink design and the multiple 140mm fans that push air through it.

This cooler is very popular in the air cooler market for many reasons, mainly its cooling performance. But Noctua has an industry-recognized aesthetic that works seamlessly in almost any build.

As per our review of the Noctua NH-D15, we showed extensively that this cooler is indeed incredibly capable, especially when facing the likes of the 14600k (the CPU we used to do our testing). That CPU has a TDP of 125w (max 181), so we know for sure that this cooler can handle the 120W TDP of the 7800X3D.

Most of this cooling prowess is generated by the 2 highly optimized NF-A15 140mm fans, with PWM and low-noise adapters for full, but silent autonomy. These fans are capable of moving air at an alarming rate and should be accompanying all CPU coolers in our humble opinion.

What users say

The Noctua NH-D15 has a 4.7 rating out of 5 on Amazon, based on 11,807 reviews. One user said: "I did not expect this beast to be the size it was, but after following the instructions and mounting it...what's that...silence. Not only silence but also temperatures that rival my old AIO liquid cooler."

This is the Ryujin III 240, and as per our review, it's almost a masterpiece. This CPU is capable of tackling flagship CPUs let alone the 7800X3D. If you need a CPU cooler that is capable of handling pretty much anything, comes in a smaller form factor, and has an LCD screen, then you're definitely in the right place.

Half of the reason this cooler can cool so well is ASUS’ ongoing partnership with Noctua to provide the Ryujin with Noctua iPPC-2000 PWM fans to help keep things cool.

The LCD screen offers basically the same functionality as the Corsair one does, only this time you have to go through ASUS Armory Crate as opposed to iCUE, which is a bit of a bummer as Armorey Crate is notorious for, well, not working.

ASUS prides itself on quality products for the most part and has been in the cooling game for a long time. This is the third iteration of the Ryujin cooler, featuring an 8th-generation Asetek pump. So you can be sure you're getting performance and quality to match.

What users say

The Ryujin III has a rating on Amazon of 4.6 out of 106 reviews, with one verified purchaser stating "You won’t be disappointed", which kind of speaks for itself, don't you think?

Features and Considerations

When selecting a cooler for the Ryzen 7 7800X3D, it's crucial to consider both its TDP rating and heat dissipation efficiency. With a 120W TDP, the Ryzen 7 7800X3D demands a cooling solution that can effectively manage its heat output, especially during intensive gaming or heavy computational tasks.

A good cooler not only maintains optimal temperatures but also extends the CPU's lifespan by preventing overheating. Air coolers and liquid coolers are both viable options, with air coolers typically being more budget-friendly and easier to install, while liquid coolers offer superior cooling efficiency and aesthetic appeal.

Your cooler needs to be compatible with the size and layout of your case and motherboard. Some coolers are lower profile than others, potentially leading to RAM clearance issues. And if you opt for an AIO cooler with a longer radiator, you'd better check that the radiator fits somewhere within your case.

Is the Ryzen 7 7800X3D easy to cool?

The Ryzen 7800X3D is relatively easy to cool. Despite being a high-performance CPU, it has a manageable TDP of around 120 watts, which doesn't typically exceed 90 watts. This means that it doesn't generate excessive heat under normal operating conditions, making it compatible with a wide range of cooling solutions, from high-end liquid coolers to more budget-friendly air coolers.

Here at PCGuide, we've reviewed loads of coolers and have put each one through intense testing to get an idea about how good they are at keeping the temps low. Based on the results, we've selected a few options that we think are right for the 14700K. So, without wasting another second, let's dive in!

How we picked

At heart, our selection process is rooted in quality research and analysis of some of the market's best offerings. We scour multiple platforms, examining user reviews and public benchmarks to understand each cooler's performance, reliability, and value. However, instead of relying solely on online ratings and reviews, we also test the CPU coolers ourselves before recommending them to our readers. After all, we don't want you to end up wasting your money on the wrong cooler. You can learn more about our testing methods through our how we test guide.

Our top picks

The ASUS ROG Ryujin III is a top-tier cooling solution and the best overall CPU cooler. Tailor-made for gamers and enthusiasts seeking the pinnacle of performance for their Intel Core i7-14700K. We gave it 4.5 out of 5 in our ASUS ROG Ryujin III review, because the cooler managed to deliver exceptional results in all our tests.

To begin with, the Ryujin III comes with a radiator that hosts three 120 mm fans. These can spin at a speed of 2,000 RPM, so it can easily keep even the hottest of CPUs cool. On top of that, there is a Copper CPU cold plate and an 8th-generation Asetek pump in the water block, which further helps with keeping the temps low. There’s also a 3.5-inch LCD screen on the water block, which you can use to display a picture or GIF. 

While the process of installing an AIO cooler is a bit more complicated than air coolers, you should have no problems with the Ryujin III. However, do keep in mind that not every case can support a radiator with three fans, so make sure to check this before getting the cooler.

It manages to keep our 14600K cool in every scenario, which is the most important factor when it comes to CPU coolers. 

As far as the performance is concerned, we tested the cooler on the Core i5-14600K, which is the little brother of the 14700K. The idle temps were 28°C, and they never went above 31°C. 

We then decided to launch the Aida64 stress test. For those who don’t know, this is the most extreme test, as it pushes the CPU to its limits. To our surprise, the average recorded temp was 61°C, and the max we saw was 77°C. Even in Blender, the max temp was 72°C.

Overall, the ASUS ROG Ryujin III is a solid cooler, and it will help keep the Core i7-14700K cool even during intense gaming and productivity sessions.

The 14700K can run quite hot, and a robust CPU cooler is required to keep it from throttling. So, if you're looking for an AIO cooler with a large heatsink and excellent cooling performance that doesn't break the bank, we recommend the Cooler Master MasterLiquid 360 Atmos.

This is a top-notch CPU cooler that managed to keep the 14600K well under wraps during stress testing, but first, we'll go over what it brings to the table. It features three 120mm fans, meaning it has a 360mm radiator, and the maximum RPM of these fans is 2,500, which gives it a noise level of 27.2dB(A).

To put it into perspective, this is quieter than a whisper, so even if they are working on full load, you shouldn't be able to hear them or get distracted while you're gaming or working. This CPU cooler also has a very straight-to-the-point design and cuts out on fancy features like an LCD on the pump block. It also features a clear and tough plastic, which provides a view into the inner workings of the cooler.

The Cooler Master Atmos cooler is one of the best coolers we have tested from Cooler Master, it preforms very well and sticks to a reasonable budget, the same can’t be said for some 360mm AIO cooler out there.

Besides that, there is some minimal RGB present, but you can turn that off if you're going for a non-RGB build. A nice accessibility feature is that the 120mm fans come preinstalled on the radiator, meaning that you just have to take it out, apply the thermal paste, mount the cooling block, install the radiator, and you're done.

There is also an RGB hub that you'll need to connect to the mainboard via USB and give it power through SATA, and the cooling block also needs to be connected to the board via USB. Regarding its performance, we used the 14600K and the RTX 4070 Ti Super.

Before starting the stress test, the idle CPU temperature was 37°C, and the air behind the radiator fans was 24.6°C. When we started the stress test, the temperature ramped up to 77°C, which is a 70% increase but is still acceptable for a processor as they tend to run hot and have an operational limit of 95° or 100°C. The air behind the fans was 27.8°C, an increment of 12%, which is amazing, meaning the tubes, CPU block, and radiator were doing an excellent job of transporting the heat and expelling it.

Overall, this is one of the best AIO coolers we've tested, and it comes at a relatively very affordable price point compared to other AIO options on the market, giving it excellent value as well. It managed to keep the 14600K cool, and we expect it to deliver the same performance with more powerful processors like the 14700K. However, to ensure efficient heat transfer from the CPU to the cooling block, we recommend using the best thermal paste.

If you don’t have the budget to get an AIO cooler or are just a fan of air coolers, then we’d recommend the Noctua NH-D15. This is a premium air cooler that can help keep your processor cool during those long gaming sessions. In our Noctua NH-D15 review, it managed to do a great job in different stress tests. 

To begin with, what makes the Noctua NH-D15 different from other air coolers in the market is its dual-fan design. Both fans can run at a speed of 1,500 RPM, which is pretty impressive. On top of that, to make sure the temps stay within safe limits, there are two heatsink stacks with six copper and aluminum vapor chambers. 

The D15 is also great when it comes to noise levels, as it generates a sound of around 24.6 dB. A whisper is between 20 to 30 decibels, so this should give you an idea of how quiet the cooler is.

The NH-D15 from Noctua is a fantastic cooler with a brilliant value for money, it is capable of cooling many CPUs in the higher end thanks to it’s double stack heatsink and dual 140mm fans.

For our review, we tested the NH-D15 on the same processor used with the ASUS ROG Ryujin III. At idle, when the PC was not doing anything, the temps stayed between 33 and 34°C. We then launched the Aida stress test, where the average recorded temp was 70°C, and the cooler didn’t let it go beyond 86°C.

In other tools like Blender and Handbrake, the average temp was 67°C and 71°C, while the maximum temperature it reached was 72°C and 82°C. So, the cooler did a remarkable job of keeping temperatures low during the intense tests. Overall, if you’re after an air cooler, then the NH-D15 is a great choice for the Core i7-14700K.

If budget is not an issue and you want an absolute beast for your rig, then you’d want to check out the ASUS ProArt LC 420. This is a premium AIO cooler from ASUS that is designed to improve the temps and longevity of high-end processors. In our ASUS ProArt LC 420, the cooler passed every test with flying colors. 

To begin with, just like the first option on our list, the LC 420 also has a 3-fan radiator. However, the fans on this one are bigger in size, as it boasts 140mm fans instead of 120mm. All three run at a max speed of 2,000 RPM, and they won’t let the CPU overheat during intense sessions.

Surprisingly, given the price it comes at, there is no screen on the water block. However, this does make the water block less bulky. The tubes are also made of sleeved rubber, so while they are extremely durable, they are flexible as well. 

This cooler is designed to be the best, and integrate seamlessly into any PC case that can accommodate is huge 420mm radiator. 

Once again, we decided to use the Core i5-14600K for our test. At idle, the temps were between 27 and 33°C. However, we then decided to test its actual performance in Aida64, where the average temp was 57°C, and the max we saw was 72°C. In Blender and Handbrake, the average recorded temp was 57°C and 60°C, while the maximum temp for both was 70°C.

Overall, the ASUS ProArt LC 420 is a great high-end cooler. Even if you decide to upgrade to a better processor in the future, you won’t have to worry about replacing the cooler.

How to choose the best CPU cooler for 14700K

When selecting a cooler for the Intel Core i7 14700K, it's vital to consider certain features tailored to its specific needs. Given its higher heat output and impressive P-core turbo of up to 5.6 GHz and base P-core frequency of 3.5 GHz, a cooler's thermal capacity plays a pivotal role. However, we listed some factors to consider so that you can make an informed decision.

TDP capacity

Coolers with higher TDP ratings are better for heat dissipation, ensuring the processor remains at an optimum temperature even under heavy workloads. For example, the Cooler Master MasterLiquid Atmos 360 has a TDP of 290W, meaning it should be able to keep the 14700K tame as it has a maximum power draw of 253W.

Ambient Temperature

A crucial factor to consider is the ambient temperature. The 14700K will be easier to cool and will get less hot if the climate is cold; however, if it is hot, its base temperature will rise, meaning the chances of its heating to its maximum temperature go drastically up. So, for this case, we recommend using a robust AIO cooler and even undervolting the CPU, as that has been shown to increase performance while taking the thermal output down a notch.

Cooler size

Another key consideration is the physical size and compatibility of the cooler. Some high-performance coolers, particularly larger air coolers, can be quite bulky and may pose compatibility issues with certain RAM modules or cases. Furthermore, noise levels can also play a role for users who prefer a quieter workspace or gaming environment.

Will a stock cooler be enough for an i7-14700K?

Realistically speaking, a stock cooler should be able to keep the 14700K from thermal throttling, but it'll be a very fine balance and will depend on the workload. The 14700K runs hot and, given the chance, will exceed the cooling capabilities of a stock cooler. So, for the best output, we recommend investing in a robust AIO or air cooler with 140mm fans and a dual heat sink to ensure efficient heat dissipation.

Does an i7-14700K need liquid cooling?

With a rather high potential boost reaching 250W, its CPU does have a lot of thermal loads to move away and prevent throttling. That could require a liquid cooler to ensure it doesn't happen, or certainly one of the bigger air coolers like the Noctua one mentioned in our list. Certainly, if you plan on overclocking, the higher ability of the AIOs might be beneficial.

Does the i7-14700K come with a cooler?

No, Intel does not include a CPU cooler with the i7-14700K. Its TDP is too high for the stock cooler to be able to do enough on it, and ensures it stays cool enough. You are more likely to find those coolers included with the lower tiers of Intel CPUs, like the i3s.

We'll find the best CPU coolers for the Intel Core i9 14900K and 14900KS. As enthusiasts and professional builders know, pairing a high-performance chip with the right cooler is crucial to ensuring longevity and optimal operation. Considering the high power of the processors it takes some cooling, and might not be ideal to go for these days considering the 285K is now out for a new platform.

That being said, we've selected a handful of CPU coolers based on their price, design, and performance after testing and reviewing them in-house. All of these had excellent performance, so you can pick one that fits your budget. Without further ado, let's get right to it.

Products at a glance

How we selected the products

Our process for selecting the best CPU cooler for the Core i9 14900K and KS is both careful and comprehensive. Ultimately, we’ve drawn on our own review of the i9 14900K, the capabilities of the faster 14900KS, and other publicly available benchmarks to ensure we have a clear understanding of how different coolers perform alongside this processor. 

While choosing our top picks for the best cooler for an i9 14900K or KS, we focused on a few key aspects and their ability to get the most out of Intel’s high-end CPU. In particular, budget, cooling capability – especially when tapping into the i9-14900K’s 6GHz overclocking potential (6.2GHz for the KS), noise levels, and build quality all played a part. To a lesser extent, desirable but non-essential features, such as RGB lighting, were taken into account.

Further, we tested these CPU coolers in-house to give you better insights into the real-world performance of these products. You can check out a detailed review of each of the coolers. 

If you want the best AIO cooler for your i9 14900K rig, then we believe that the Corsair H150i LCD XT is one of the best AIO options on the market right now.

To start with, this is probably one of the largest coolers you can get from the brand. It has three fans placed on a 360mm radiator, which should give you an idea of the powerful performance it can deliver. 

In our review, we tested the CPU to see the performance for ourselves. We tested for everyday performance as well as pushed it probably far beyond anyone would under standard use. And the CPU did very well. 

We tested for everyday performance as well as pushed it probably far beyond anyone would under standard use. And the CPU did very well. 

To be more specific, while idle, the average temperatures were 27 and 29 degrees under full fan and balanced modes, respectively. These numbers are not too far away from the ambient liquid temperature of 28.13 degrees. 

Further, during the 5-minute Aida stress test, the temperatures under full-fan and balanced modes were 79 and 84 degrees, respectively. While these numbers may seem high, note that these are extreme scenarios that are unlikely to occur during everyday use. 

As far as design is concerned, there are two parts in the block - one contains a water pump and the other has a 2.1-inch LCD screen on the top. This separation makes installation easier and minimizes the chances of damaging the screen. Plus, the screen can display system info or you can choose to display memes. 

If you have a creative workstation with a powerful CPU like the 14900K, then we think that the ASUS ProArt LC 420 is the best choice.

Much like the name suggests, the ProArt is a cooler designed for creatives or people who regularly put a lot of strain onto their CPU. As mentioned, this cooler comes with a big 420mm radiator - so you’ll need to ensure that your rig can accommodate it. 

Much like some other Asus coolers, this one also features fans from Noctua. To be specific, this cooler has Noctua NF-A14 Industrial PPC-2000 140mm fans that are capable of delivering 2000 RPM, which explains how efficient this cooler can be.

We have reviewed this cooler in-house, and right off the bat, we’d say that we liked it. The cooler is big and it is expensive, but it’s worth the price if you have a powerful rig. However, if you don’t strain your system a lot, then you can consider going for a 360mm cooler. 

We have reviewed this cooler in-house, and right off the bat, we’d say that we liked it.

During our review, we stress-tested the cooler in idle condition as well as the Aida test - and it performed very well. To give you a better idea, the temperatures did not exceed 33 degrees and 72 degrees at idle load and extreme load, respectively. These are pretty impressive numbers. We also tested the temps for Blender, for which we’d encourage you to read our detailed review.

Overall, this is a robust cooler that can handle high-performing CPUs like the i9-14900K. Plus, there is considerable headroom here if you decide to upgrade your CPU in the future.

If you want a more reasonably priced cooler for your i9-14900K rig, then the Cooler Master MasterLiquid 360 Atmos might be a good fit.

As mentioned, this is one of the most affordable picks on this list, and yet the performance is on par with some of the costlier coolers that we have tested. However, it lacks fancy features like an LCD display, which might actually appeal to users who like to keep it basic. Overall, it’s a no-nonsense pick in terms of design and performance. 

Another thing that we’d like to note is that the Sickleflow edge fans come pre-installed, so you can skip a step during installation. Plus, these fans can spin up to 2500 RPM and deliver 70.7 CFM of air, with a 27.6 dB(A) max noise level. 

This is one of the most affordable picks on this list, and yet the performance is on par with some of the costlier coolers that we have tested.

We tested the Cooler Master MasterLiquid 360 Atmos, and we were pretty impressed with the results. In the idle state, the cooler managed to keep the average temperature at 28 degrees. Meanwhile, during the Aida stress test, the average temperature was 59 degrees and it did not exceed 77 degrees. All of these are impressive numbers for a cooler at this price.

As far as design is concerned, it doesn’t have too many bells and whistles. It looks sleek and attractive, and you can choose between black and white options. Instead of a screen, you get a window through which you can see the heat sink and other parts. Plus, you also get RGB lights that you can turn off. 

This selection might be surprising, as an air cooler is generally not enough to tame Intel's flagship processors. However, we've reviewed the Noctua NH-D15, and it managed to keep the 14600K at an acceptable temperature, so it should be able to handle the 14900K as long as it isn't overclocked.

This CPU cooler has a copper contact plate mounted on top of the CPU and comes with high-quality thermal paste pre-applied. However, it is generally believed that you should change your thermal paste at least once a year, so we recommend using the best thermal paste available to ensure that the heat is efficiently transferred from the CPU to the cooler.

That being said, it features dual aluminum heatsinks, which have six vapor chamber heat pipes going through them each, making them 12 in total. There are also two 140mm fans that can be attached to the dual heatsinks, but be careful while doing so, as there is the risk of cutting yourself on the heatsink.

The NH-D15 from Noctua is a fantastic cooler with a brilliant value for money, it is capable of cooling many CPUs in the higher end thanks to it’s double stack heatsink and dual 140mm fans.

The noise level of the Noctua NH-D15 comes to around 24.6 dB(A) while it is pretty quiet, and you shouldn't heat it running. There is also the option of enabling quiet mode, but the performance takes a hit with that turned on, so we don't recommend doing that, especially with the 14900K.

To check its cooling performance, we paired it with the 14600K, which has a maximum TDP of 181W, while the 14900K sits at 253W. So, there is a clear difference, but while running the Aida stress test, this cooler kept the 14600K at 86°C with zero thermal throttling. That being said, for causal usage, it should be able to keep the 14900K cool and prevent overheating. We also recommend using powerful 140mm case fans to promote good airflow.

Features and considerations

Here are a few things to consider before getting a cooler for your rig -

Compatibility

Furthermore, compatibility is of paramount importance. It’s essential to ensure that the cooler fits comfortably within your case without obstructing RAM or other essential components. After all, a cooler that’s too bulky might impede airflow or even prevent the case from closing properly. You’ll need to consider where the radiator will sit, whether on top, on the side, or on the bottom, and how this will impact intake and outtake airflow.

Type of cooler

You will come across two types of coolers - AIO (liquid) and Air. Generally, liquid coolers offer superior heat dissipation for overclocking or high-performance tasks. However, you'd need to check case compatibility for radiator size and tubing management. Meanwhile, air coolers are quieter and easier to install but may not be as effective for very demanding use cases.

Noise levels

Coolers can get noisy and cause distractions, so you should look for a cooler that's not too noisy. Look for coolers with PWM (Pulse Width Modulation) fans for quieter operation at lower CPU loads. Aim for a cooler in the 30-40 dB range at idle and ideally below 50 dB under load for a quiet PC experience.

Aesthetics

Coolers come in all kinds of shapes, sizes, and colors, so you can be a bit picky with style. A lot of coolers feature RGB lights that you can customize as per your preferences. Some high-end options come with an LCD screen that can display system information or even memes. If you don't want any bells and whistles, then you can choose a no-nonsense design.

Is air cooling enough for 14900K?

While we would generally recommend investing in an AIO water cooler instead, air cooling can be a valid and cost-effective option for those after a cheaper way to keep their chip chilled. The one we’ve included in our roundup has enough grunt to work well, but you won’t be able to overclock or push your games as hard. You have to get a big enough one to cover the 253W max turbo power, but beware it can go even higher so might be best to aim for even more.

Will a 240mm AIO cool a 14900K?

Yes, a 240mm radiator and pump combo should be enough to adequately cool an i9 14900K. We would recommend going for a 360mm if you have a large enough PC case for overclocking overhead, but you shouldn’t experience any issues with a slightly smaller radiator mounted.

What is the best CPU cooler for 14900K?

From our testing and selection, there are a few options to go for. In our top spot is the Corsair H150i ELITE LCD XT, that provides plenty of cooling capacity to keep the CPU under wraps, with the AIO offering a large radiator and plenty of fans. There is also the ASUS ProArt LC 420 as a premium option with an even bigger radiator to give the 14900K an even bigger fighting chance. But if air cooling is more for you, the Noctua NH-D15 is our recommendation.
