ASUS Zenbook UM3402YA: fan doesn't work at all

Hi everybody! Thanks for your time.

I’m pretty new to Linux, bought new ASUS laptop - without any OS (of course, by “no OS” ASUS only means “you should install Windows yourself”). First I installed Ubuntu - and here is the thing: before the first installation the fan was working - I heard it pretty much clear and I saw RPM value in ASUS UEFI (BIOS), so I’m sure that the fan is physically ok. But since Ubuntu was installed (or while it was installing - I’m not sure) the fan is not working at all at any load (up to 95 C), and, which is more surprisingly, including ASUS UEFI - the RPM value always “0” now (ASUS UEFI don’t have any options to manipulate fan control).

After that I installed Manjaro (and I liked it) since it’s rolling release concept (and access to AUR), and tried different kernels - but that doesn’t fixed my fan issue.

I’ve tried everything I found on this topic (including “Fan speed control” on ArchWiki) :

  • lm_sensors: sensors-detect result - “Sorry, no sensors were detected.”
Full sensors-detect result
# sensors-detect version 3.6.0+git
# System: ASUSTeK COMPUTER INC. Zenbook UM3402YA_UM3402YA [1.0] (laptop)
# Board: ASUSTeK COMPUTER INC. UM3402YA
# Kernel: 6.3.0-1-MANJARO x86_64
# Processor: AMD Ryzen 5 5625U with Radeon Graphics (25/80/0)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): y

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): y

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.

Sorry, no sensors were detected.
This is relatively common on laptops, where thermal management is
handled by ACPI rather than the OS.
  • My /sys/devices/platform/asus-nb-wmi/hwmon/hwmon[[:print:]]* (hwmon5) directory don’t have pwm1 or pwm1_enable files. Also I can’t create them manually (even if I’m root after sudo -i) - getting “Permission denied” error.

  • Installed everything I could find to control fan, but nothing work (asus_fan, etc - I don’t even remember every single thing I found).

  • Also tried (desperately) to change GRUB_CMDLINE_LINUX_DEFAULT to ““quiet splash acpi_osi=LINUX”” in /etc/default/grub and update-grub, but that doesn’t work ether.

  • Even tried to add “acpi=off” to GRUB_CMDLINE_LINUX_DEFAULT, but that only teached me how to do update-grub from live-usb :upside_down_face:

  • Got my UEFI updated (not sure that it was an update at all - current UEFI version from ASUS official site dated august 2022, - but installation from UEFI was successful).

Appreciate any of your help - I’m out of ideas.

P.S. Yes, I also have common problem with no audio with this laptop model, but that doesn’t bother me much right now since I use bluetooth-headfones anyway, and no audio seems like something uncomfortable while no fan can permanently destroy my laptop.

Thanks for reply! As I’ve mentioned above, I already tried that, but may be I do something wrong?

The directory have no “pwm1” and/or “pwm1_enable” files:

~ ls -la /sys/devices/platform/asus-nb-wmi/hwmon/hwmon[[:print:]]*

If I’m trying to create them, I get an error:

or

or

/sys/devices/platform/asus-nb-wmi/hwmon/hwmon5 sudo -i

P.S. Apologies for my English.

Kernel: 6.3.0-1-MANJARO

This kernel is in my Manjaro Settings still marked as ‘experimental’ release candidate, I doubt it’s used in any Ubuntu yet, maybe install the 6.1LTS.

This may have something to do with the kernel, see here: Want to change ATI fanspeed permission denied / Kernel & Hardware / Arch Linux Forums .

Yes, I currently run 6.3.0rc3-1 kernel, but just because I’ve tried 6.1.21-1 (at first) and 6.2.8-1without any success. Actually, I don’t have any requirements to run one or another kernel - this laptop is new so I can easily wipe everything up and reinstall OS from scratch. I just want this fan to work) BTW, I don’t plan to go back on Ubuntu)

This may have something to do with the kernel, see here: Want to change ATI fanspeed permission denied / Kernel & Hardware / Arch Linux Forums .

So it seems like files aren’t there because the kernel doesn’t suppose them to be there. Therefore, even if I could create them, they probably wouldn’t get used by the kernel anyway? Seems like dead end, at least, for “asus-nb-wmi pwm files” approach.

Can I try something else? Without working fan this laptop will not last long, I guess.

The most interesting question for me is: why the fan worked when there was no OS at all, and stopped - even in UEFI, after? I thought that UEFI manage fan by itself, even if after OS boot the management goes to OS. So I expected that I’ll get working fan at least in UEFI, but it’s “0 RPM” there now :face_with_raised_eyebrow:.

But why was it working in ubuntu? As far as I know they’re using the older 5.15LTS in their ISOs, maybe that’s worth a try especially since 6.1LTS was only recently made an LTS.

But why was it working in ubuntu?

It wasn’t.
Right after I installed the OS first time, the fan stopped.
Yes, the first OS was Ubuntu, but I think, most importantly, that it was Linux - and since kernel that Ubuntu uses (~5.15LTS), till my current Manjaro 6.3.0rc3-1, there is no support for my “some-hardware” that responsible for this low-level fan management.

The fan worked only when there was no OS at all (there was UEFI only on my laptop right after I bought it).

BTW, I tried different kernels on Ubuntu too (from LTS to experimental) - no effect.

But thank you anyway)

I’ve also tried all available LTS kernels:

  • 6.1.21-1 - no fan
  • 5.15.104-2 - no fan, but also no wifi
  • 5.10.176-2 - can’t boot
  • 5.4.238-1 - can’t boot
  • 4.19.279-2 - can’t boot

And some others:

  • 6.3.0rc3-1 (experimental) - no fan
  • 6.2.8-1 - no fan
