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 -- http://thisurlenablesemailtogetthroughoverzealousspamfilters.org
