 |
|
I seem to have my hardware sensors up and working with kernel 2.6.12.2
I can get my CPU and MB temperatures, as well as fan speeds for my CPU and my case fan.
The PSU fan does not report a value, however, and `sensors` reports it running at 0.
The sensor works in windows, and I know it to be running at about 780RPMs.

( I know some voltages are off, but I don't care about those at the moment  )
EDIT - upon switching my CPU and PSU fan connectors around, it seems that it just won't read the PSU fan, and that the port itself is A-OK |

Slow fans won't register with a small fan divisor, due to the way the sensor chip measures the rpms. You need to increase it. 2 is ok for 2500+ rpm, 4 for 1300+ rpm, 8 for 650+ rpm. So you want 8. For more info on divisors, look here.
Edit /etc/sensors.conf, and find the section for your sensor chip. In it add that line:
Then run (as root):
