The driver turns off the fans for acoustic reasons if the OEM enabled support for the feature in the vbios. They will still go on when the temperature gets high enough.
Ok. I checked again and the fan does turn on when playing a game (gzdoom).
Too bad it's the quietest fan in my PC :)
I guess I panicked.
If this is the expected behaviour then this bug can be closed.
Thank you.
