Stranger things with Corsair Commander Core #623
Description
Describe the bug
All sorts of misbehaviour including:
- Failure to increase rmp to target fan speed percentage
- Failure to decrease rmp to target fan speed percentage
- Weird error messages on some set fan speed commands but not on others
- Total failure to respond to any command whatsoever (that can only be helped by booting windows and forcing a firmware update to corsair commander core)
Commands executed
We see that (1) the fans do not reach full speed when after set fans speed 100 (because fan groups 2 and 6, that have max rpm of 3000 are at 2771 and 2661 respectively). We see (2) errors on setting lower fan speeds. We see (3) fan rpms getting "stuck" at high load even when there is no error. Finally (4) we see that if we repeat the command the fan speeds do come down.
