--- Comment #2 from Fabian plusfabi@gmail.com --- Is there some kind of live-image? I just can not switch to another distro, since I need to work with this computer.
Are you sure it is the gpu fan?
Yep. I can just write "0" to /sys/class/hwmon/hwmon2/pwm1 and its quiet.
This btw wasnt the case since the beginning.There was a Kernel and/or linux-firmware release that brought this bug in. I just cant figure out wich Version it was.
