Still, if I can't control the fan speeds but they are instead controlled by some onboard controller, then how could the installation on the fancontrol and lm-sensors mess up the control loop so bad? This still keeps me wondering. Maybe, the sensors somehow blocked the CPU temperature readout. This could have caused the superdoctor program to resort to some failsafe behavior (i.e. spinning the fans up to max RPM). Just wondering. > Since then I didn't manage to regain control of the fans.

Thank you, I already tried that -- without success.
