I've installed the last version of Ubuntu (20.04) and I have an issue with my fan : even if my CPU temp is low my fan is working at max speed :(
I use sensors
to check temp and fan speed :
# sensors

Adapter: ISA adapter

I've tryed to reduce speed manualy using i8k
:
# i8kfan 1 1
2 2
I can hear the fan slowing down and then speeding up again (1 or 2 seconds after).
Can any one help me ?
