Fans detected by asuswmisensors-isa-0000 are uncontrolable

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 ?

Hi there,

At the moment the driver does not have the ability to set fan speeds, the only thing I can suggest is setting fan curves in the UEFI.

The WMI interface contains some clearly named methods for reading sensor statuses, and then a load of methods with generic names. There is nothing obvious to set fan speeds. (see below)

I think there is a possibility that these generic methods are used by the Windows AISuite software, however we would need to discover which method to use. My attempts at determining what AISuite does by attaching a debugger and watching what API calls it makes have so far been unsuccessful.

The other option would be attempting to fix up the out of tree it87 driver to work correctly on current kernels. I had hoped that someone might have managed to do this, but I don't believe anyone has done it yet.

If I can help you running any tests, feel free to contact me.
I have no experience developing this low level stuff, and have no knowledge of the Windows internals. So depending on what you want, you might need to guide me.

Hello, any update on this? I am on an Asus ROG Strix B450-F Gaming and I believe I am encountering this same issue. When I run sensors-detect I get a warning telling me that "ITE IT8665E Super IO Sensors" doesn't have a driver in the kernel, which I believe might be the device capable of addressing the pwm values in the motherboard. This led me to the it87 module which I tried to load after removing the asus_wmi_sensors one, but without success since it outputs an error saying that there is no device for that module
