Beautiful design, great colors, works great but I could not install this on my motherboard. I did read that the lower profile might conflict with tall memory on certain motherboards, and they were right. Could not use this on my newer motherboard with the Corsair RGB ram. Just wouldn’t fit but I replaced my older intel CPU cooler on my work machine and it looks great! Quite, colorful and cools nicely.
Make sure the memory clearances and placement do not conflict with the cooler. Pay attention to the dimensions. Still gave it a 5.

Great product! Works great for me! However...
It's a great product. Keeps my CPU at around 40 Degrees Celsius, and Only had problems in the beginning with the lighting because my stupid butt plugged it in wrong. Anyways, There is a flaw... If you have more than 2 sticks of ram on a dual channel mobo, it won't work if your ram is bulky, like most RGB ram sticks. Only 2 sticks will fit on the OUTER dimm channels as the CPU itself will expand outwards and cover the ram slots. If you can see in my pic, the two red Corsair RAM sticks, you only see two. That's not because my mobo only fits two, no. It's because the other two slots are covered up by the CPU. Now this isn't a problem for me, as I only ever had two sticks myself. #brokecollegekids, But for anyone who wants to fit ram sticks under there, one, it's gonna be a pain in the arse to get it there with the cooler already on, and two, you can't have a thick, fancy, RGB stick there as it will protrude outwards too much and ultimately not fit. Just a warning if you have more than 2 sticks. or if your dimm slots are limited to two and are less than a centimeter away from the CPU slot...

So far this thing works and looks great! The lights work well, and the fan makes no noise. It’s on an i3-10100 so the cpu doesn’t generate much heat anyways, but it has yet to exceed 55C with this cooler on it. Been gaming at 1080p with most games hitting 70-100fps. This cooler is working quite nicely. I would be curious to see how it does on a more powerful cpu though. It was pretty easy to install, it comes with a special tool to tighten it down which is cool cause the shape makes it hard to get to the screws otherwise.

Optik ist der Hammer, allerdings recht laut, kein luftgeräusch sondern eher eine Art gelegentliches Schleifen, allerdings nur bei bestimmten Drehzahlen. Kühlung ist ok aber könnte für den Preis besser sein!AndreasLaut

Looks great, great at cooling.
Style: Top DownColor: RGBVerified Purchase
First of all, this fan looks stunning. Even if you don't have an RGB controller, if has a little remote to cycle through modes and colours. Not all colours are available to you with the remote, unless you do the full rainbow cycle. As for noise it isn't bad!LiamLooks great, great at cooling.
Reviewed in Canada on December 18, 2018
Under max load of an i5 8600k (Not overclocked), temperatures get no hotter than 64C.
Keep in mind if you're using aura sync, this needs a 12V, 4-pin RGB header, not the 3 pin addressable one.
