--- Comment #4 from Jimi <JimiJames.Bove at gmail.com> ---
Is this bug still happening? With my R9 Fury on amdgpu, cat
/sys/class/hwmon/hwmon0/pwm1 (well, in my case, it's hwmon2 because I have
another card), returns 35 on idle, not 0, but the fans are not running. Even
when I'm running a AAA game, my card doesn't even reach 40°C, so my cooling
system is too good for me to be able to actually see if the fans turn on when
they should. When I first started my computer up, pwm1 was giving me 56, but it
went down to 35 before I could finish opening my case and has stayed there no
matter what I do. When the card is bound to vfio-pci instead of amdgpu (for a
virtual machine), the fan is on all the time, even though the card's low idle
temperatures must be similar.
