I looked for solutions everywhere, but couldn't find it.

My Motherboard is the Asus X470-F, running third gen Ryzen, with bios version 5406
Linux 5.4.6-2-MANJARO

Here is the output for sensors -u and pwmconfig

[auyer@darkforce ~]$ sudo 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 asuswmisensors
   hwmon1 is asus
   hwmon2 is k10temp
   hwmon3 is amdgpu
   hwmon4 is hidpp_battery_0

Found the following PWM controls:
   hwmon3/pwm1           current value: 35
hwmon3/pwm1 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) 


Any ideas ?
