Fans not working

I have this model: OMEN by HP Gaming Laptop 16-wd0xxx
I'm trying to get my fans to work (won't turn on at all) so I tried following the Lm_sensors guide , then went to the Fan speed control to use fancontrol. When running

sensors

I get this output:

Other sensors

I also tried running

acpi -t

which returned this:

Thermal 0: ok, 10.0 degrees C
Thermal 1: ok, 27.8 degrees C

nvidia-smi

returns this:

Back to fans

After running

pwmconfig

I'm going to assume that I don't have PWM. Output:

# pwmconfig version 3.6.0+git
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.

/usr/bin/pwmconfig: There are no pwm-capable sensor modules installed

Conclusion

I don't know what I'm doing. Any help or guidance would be appreciated. I'm considering using Wine to run Omen Gaming Utility.

Re: Fans not working

I feel like Wine+Omen Gaming Utility might not work because wine isn't the same as running directly on windows and we're dealing with hardware. (it's still worth a shot though if you don't have anything else).

In that case, I'd recommend booting a different OS from a stick just to see if it's an archlinux issue or something else.

When is the last time/setup you saw the fans working?

Re: Fans not working

Also note that generally speaking direct fan control from the OS is in the vast majority of laptop implementations not intended and it will be configured in a UEFI/BIOS level - if you can adjust anything at all. Is this an actual issue, have you tried running something demanding, are you running into heating/throttling issues in that case? According to that sensors output your temps are currently fine and many modern systems will simply not run the fans if there's no need.

True. I have a dual-boot with Windows 11 / Arch, so I see them running whenever I'm on Windows.

I'll check my BIOS to see if there's anything there.
I have a dual boot with Windows 11 / Arch, on which I use Windows 11 for gaming or other moderate tasks. The fans will be running anywhere from 3000-6500 RPM but when I switch to Arch there's no fans. Personally, the temperature levels seem a little low for CPU/GPU use, especially after switching.

Update

I checked my BIOS. It has a "Fan Always On" option. I'll probably just do that.
