# pwmconfig revision 5770 (2009-09-16)
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/device is coretemp
   hwmon1/device is coretemp
   hwmon2/device is w83627dhg
Found the following PWM controls:
   hwmon2/device/pwm1
   hwmon2/device/pwm2
hwmon2/device/pwm2 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n) n
   hwmon2/device/pwm3
   hwmon2/device/pwm4
Giving the fans some time to reach full speed...
Found the following fan sensors:
   hwmon2/device/fan1_input     current speed: 0 ... skipping!
   hwmon2/device/fan2_input     current speed: 2311 RPM
   hwmon2/device/fan3_input     current speed: 0 ... skipping!
   hwmon2/device/fan4_input     current speed: 0 ... skipping!
   hwmon2/device/fan5_input     current speed: 0 ... skipping!
Warning!!! This program will stop your fans, one at a time,
for approximately 5 seconds each!!!
This may cause your processor temperature to rise!!!
If you do not want to do this hit control-C now!!!

There is either no fan connected to the output of hwmon2/device/pwm1,
or the connected fan has no rpm-signal connected to one of
the tested fan sensors. (Note: not all motherboards have
the pwm outputs connected to the fan connectors,

Testing is complete.
Please verify that all fans have returned to their normal speed.
The fancontrol script can automatically respond to temperature changes
of your system by changing fanspeeds.
Do you want to set up its configuration file now (y)? n
