Hi,
While we're at it, the fan speed sensor reports an absurd speed when the fan
is driven with very low but non-zero pwm values. For example, driving it
with pwm=2 I get speeds over 50K rpms, while of course the fan is stopped
(almost?). This could be just an hardware sensitivity problem in the sensor
chip, or a false measure triggered by fan vibration, but maybe you know
better.
/Simone
