Laptop fans are contantly on, even when laptop is set to sleep

Hello everyone,

Fans on my new laptop are constantly on, even when laptop is set to sleep!
The fans are in a very slow speed, barely audible, but they are clearly on.
They also seems to be constantly on the same speed, whatever the load is.

My laptop Asus ProArt P16, model from 2024, AMD Ryzen AI 9 HX 370, with integrated Radeon 890M and with dedicated GPU Nvidia.

I can see this errors in dmesg in the general startup of the system:

espinosa@espinosa-asus:~> dmesg | grep error

I can see no errors related to the suspend in dmesg output. All looks very orderly.
I’m happy to upload my dmesg output in full; it’s not directly supported by this forum.

Any thoughts?

@espinosa_cz If you as root user run sensors-detect --auto then can you see any fan information in the output from sensors command?

In nvidia-smi output do you see any fan speed?

The temperatures are low, and yet all 3 fans are on.
Luckily, they are very quiet, barely audible, so they don’t bother me.

Sorry, no sensors were detected.
This is relatively common on laptops, where thermal management is
handled by ACPI rather than the OS.

Anyway, what bothers me the most is that the fans are on while the laptop is on suspend!

@espinosa_cz well you could use pwmconfig to tweak? Else perhaps power profiles, not sure of the status of TLP…

Or are there BIOS settings for fan control?

6

sensor gives for all PWM’s N/A and sensor-detect gives:

So it looks like fan control can only be controlled using ACPI.

Please install acpi and run acpi -V, on my desktop that gives:

Can you share the output for the labtop?

I can set hardly anything in UEFI/BIOS.
Drive booting priority and few things around Secure Boot in advanced mode, that’s about it.

That is I think a good sign without me having experience with it.

Maybe this is helpful:

https://docs.kernel.org/admin-guide/acpi/fan_performance_states.html

With ls -1 /sys/devices/ (please share the output) you can check for such a fan “_FPS object”

Edit timeout did hit so an new message instead of adding it to the previous.

Update about the fans during suspend to RAM. It’s not really issue with fans, it’s a general issue of my laptop not being able to suspend to RAM properly.

Good news is, it works in kernel 6.12.x!
And openSUSE still officially provides this kernel. Kudos to openSUSE!

There seems to be a bug, a regression in kernel 6.13.x in AMD GPU driver.
The failure to suspend to RAM is related to this error message in my logs:

amdgpu 0000:65:00.0: [drm] REG_WAIT timeout 1us * 10 tries - optc3_lock line:128

Under kernel 6.12.x I don’t see this error message and suspend to RAM works perfectly

I have reported the suspected kernel bug as:
https://bugzilla.opensuse.org/show_bug.cgi?id=1238204
