You can set up fancontrol or put 0 into pwm1 manually
to stop the fan. But putting 0 into pwm1_min is IMHO
quite useless, it can as well just not exist at all.
But if it will contain the minimum _safe_ value, then
that can well be used.
Currently fancontrol have to "evaluate" the minimal
safe value by hands. It lowers the pwm1 value and looks
when the fan have stopped by checking the value of
fan1_input if that exists. And it doesn't exist for
amdgpu, so you need to do such a probe by hands.
