Hi,
I've almost got a completely working lm-sensors 3.0.0 on my Asus
A7v8x. Everything is working apart from the Chassis Fan readout. For
some reason as the fans speed decreases, sensors reports the RPM as
increasing. The CPU and Power Fan readouts work correctly (as the fan
speed decreases the reported RPM decreases). I'm using the Ubuntu
2.6.24-16-server kernel. Can anyone suggest a way of fixing the
readout or help me figure out what is wrong?
Here is the output normally (with the Chassis Fan at full speed), the
RPM matches what the BIOS reports:
# sensors

CPU Temp (AMD): +41.0??C (high = +80.0??C, hyst = +75.0??C)
cpu0_vid: +1.800 V
As I decrease the fan speed, the Chassis Fan RPM increase:
