apt install pwmconfig fancontrol

root@pve:~# pwmconfig 
# 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 acpitz
   hwmon1 is nvme
   hwmon2 is coretemp
   hwmon3 is nct6798

Found the following PWM controls:
   hwmon3/pwm1           current value: 255
   hwmon3/pwm2           current value: 255
   hwmon3/pwm3           current value: 255
   hwmon3/pwm4           current value: 153
   hwmon3/pwm5           current value: 153
   hwmon3/pwm6           current value: 255
   hwmon3/pwm7           current value: 255

Giving the fans some time to reach full speed...
Found the following fan sensors:
   hwmon3/fan1_input     current speed: 0 ... skipping!
   hwmon3/fan2_input     current speed: 2732 RPM
   hwmon3/fan3_input     current speed: 0 ... skipping!
   hwmon3/fan4_input     current speed: 0 ... skipping!
   hwmon3/fan5_input     current speed: 0 ... skipping!
   hwmon3/fan6_input     current speed: 2119 RPM
   hwmon3/fan7_input     current speed: 2596 RPM

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 hwmon3/pwm1 ...
  hwmon3/fan2_input ... speed was 2732 now 2732
    no correlation
  hwmon3/fan6_input ... speed was 2119 now 2188
    no correlation
  hwmon3/fan7_input ... speed was 2596 now 2428
    no correlation

No correlations were detected.
There is either no fan connected to the output of hwmon3/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,
check out the hardware database on http://www.almico.com/forumindex.php)

Did you see/hear a fan stopping during the above test (n)? n
