This program will search your sensors for pulse width modulation (pwm)
4
controls, and test each one to see if it controls a fan on
5
your motherboard. Note that many motherboards do not have pwm
6
circuitry installed, even if your sensor chip supports pwm.
7
We will attempt to briefly stop each fan using the pwm controls.
8
The program will attempt to restore each fan to full speed
9
after testing. However, it is ** very important ** that you
10
physically verify that the fans have been to full speed
11
after the program has completed.

Found the following devices:
13
   hwmon0 is acpitz
14
   hwmon1 is nvme
15
   hwmon1 is coretemp
16
   hwmon1 is nct6798
17
Found the following PWM controls:
18
   hwmon1/pwm1           current value: 255
19
   hwmon1/pwm2           current value: 255

24

Giving the fans some time to reach full speed...
26
Found the following fan sensors:
27
   hwmon1/fan1_input     current speed: 2521 RPM
28
   hwmon1/fan2_input     current speed: 0 ... skipping!
29
   hwmon1/fan3_input     current speed: 0 ... skipping!
30
   hwmon1/fan4_input     current speed: 0 ... skipping!
31
   hwmon1/fan5_input     current speed: 0 ... skipping!
32
   hwmon1/fan6_input     current speed: 0 ... skipping!
33
   hwmon1/fan7_input     current speed: 0 ... skipping!
34
Warning!!! This program will stop your fans, one at a time,
35
for approximately 5 seconds each!!!
36
This may cause your processor temperature to rise!!!
37
If you do not want to do this hit control-C now!!!
