I wrote a script like this that works on my laptop. Maybe someone will need...

It seems newer CPUs and related hardware are not supported...

Not so terrible then, since I can directly set fan RPM with
sudo echo 0 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon4/pwm1_enable.
But there is a problem that, hwmon changes, after every reboot of the laptop and I don't know how to fix it. Do you have any ideas?
Thank you very much in advance

I receive the same AE_NOT_FOUND error on my desktop ASUS PA90.

Running ubuntu linux 23.04 (GNU/Linux 5.19.0-23-generic x86_64)

My fan runs loud/high since upgrade to 23.04.

sensors-detect returns these:
Driver `coretemp':

• Chip Intel digital thermal sensor' (confidence: 9) Driver nct6775':
• ISA bus, address 0x290
  Chip `Nuvoton NCT6796D Super IO Sensors' (confidence: 9)

And sensors give this:

And fancontrol says this:

Some mandatory settings missing, please check your config file!

Maybe you can use a similar approach to AFC's. Have a look at the installation script https://github.com/dominiksalvet/asus-fan-control/blob/master/.install/install-global-Linux and focus on afc.service file. That could be helpful.
