Just purchased an AMD R9700, and it is unbearably loud at idle. I cannot adjust the fan speed or curves to get below 50%. In my configuration.nix, I have boot.kernelParams = [ "amdgpu.ppfeaturemask=0xffffffff" ];. I'm on kernel 7.0.5, on the latest unstable release, with gfx 1201.

Using LACT, I have adjusted the fan curve to stay at 20% under most temperatures, but amdgpu_top shows what LACT thinks is 20% is the mind-numbingly loud 50%.

LACT fan curve (not what I would ideally have, but I can't adjust the fan curve below 20%, which is actually 50%)

With my fan curve set to the above image, amdgpu_top shows this:

amdgpu_top fan curve

Modifying LACT's configuration.yaml file manually to below a 20% fan curve also does not work. Failed to set curve fan control: Invalid fan curve: Speed 10% is outside of the allowed range 20% to 100%

Any help is appreciated, thanks.
