# pwmconfig version 3.6.0
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 fam15h_power
   hwmon1 is k10temp
   hwmon2 is it8728

Found the following PWM controls:
   hwmon2/pwm1           current value: 75
   hwmon2/pwm2           current value: 70
hwmon2/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) 
   hwmon2/pwm3           current value: 96

Giving the fans some time to reach full speed...
Found the following fan sensors:
   hwmon2/fan1_input     current speed: 729 RPM
   hwmon2/fan2_input     current speed: 882 RPM
   hwmon2/fan3_input     current speed: 0 ... skipping!
   hwmon2/fan4_input     current speed: 0 ... skipping!
   hwmon2/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!!!
Hit return to continue: 

Testing pwm control hwmon2/pwm1 ...
  hwmon2/fan1_input ... speed was 729 now 0
    It appears that fan hwmon2/fan1_input
    is controlled by pwm hwmon2/pwm1
Would you like to generate a detailed correlation (y)? 
Note: If you had gnuplot installed, I could generate a graphical plot.

    no correlation

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)? 
What should be the path to your fancontrol config file (/etc/fancontrol)?
