nelis@nelis-desktop:~$ pwmconfig
# pwmconfig revision 5630 (2009-01-29)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

Found the following devices:
   hwmon0 is acpitz
   hwmon1/device is k8temp
   hwmon2/device is f71862fg

Found the following PWM controls:
   hwmon2/device/pwm1
   hwmon2/device/pwm2
   hwmon2/device/pwm3
There are no usable PWM outputs.
