            Bug ID: 221569
           Summary: Laptop fan too loud (spinning nearly always) hp-wmi
                    7.1-rc4 kerenel
           Product: Drivers
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Platform_x86
          Assignee: drivers_platform_x86@kernel-bugs.osdl.org
          Reporter: moravec@ukf.sk
        Regression: No

Hello, I'm testing 7.1 kernel tree end seeing much louder fan on my laptop even
when system is idling. CPU fan is spinning nearly all the time even CPU
reported temperatures are low. Currently:

migo@migo-HP:~$ uname -a
Linux migo-HP 7.1.0-rc4-00685-g4cbfe4502e3d #45 SMP PREEMPT_DYNAMIC Sun May 24
12:47:18 CEST 2026 x86_64 GNU/Linux


In 7.0 kernel tree is my laptop much quieter, fan spins only sometimes and with
lower RPM.

Machine is: HP OmniBook X Flip Laptop 16-ar0xx, with Arch Linux installed.

Is there any way I can make more exact/useful report or debug this issue?

Thank you!

I've no idea, but you could bisect:

https://docs.kernel.org/admin-guide/bug-bisect.html

to speed up the process of identifying the bad commit and fixing the
regression.

OK, thank you, I'll wait for final 7.1 and then when not fixed I'll do
bisection. Is it OK?

Well, then a lot more people might run into this (depending on how many
machines this affects), unless somebody else runs into the problem and fixes
it. But I haven't seen any similar reports. So waiting might just delay things
and broaden the impact.

Can you maybe share the full dmesg from 7.0 and one from 7.1-rc, too?

Thx. Can I CC you when forwarding this by mail? This would expose your email
address.

Yes, you can. I've tried do switch Power mode to Powersave (via Gnome menu) to
lower/disable FAN RPMs and got this error in dmsg:

jún 01 09:34:30 migo-HP kernel: platform_profile: Failed to get profile for
handler hp-wmi

but this is error is present in 7.0 too, so this is not new in 7.1 tree.

load is low:

All temperatures are low BUT wifi module reports: temp1: +82.0°C, I don't know

that's odd; is the wifi temp high with a working kernel, too? And could you try
to block the wifi driver from loading to see if it makes a difference?

I'll try with 7.0 tree after the work. I'm using wifi as only net connection,
so blacklisting is not a good idea here.

Just now is reported wifi temp. OK:

mt7925_phy0-pci-6200
Adapter: PCI adapter
temp1:        +47.0°C 

But FAN is still 2100RPM :( 

load is low:

migo@migo-HP:~$ w

Please also check if the CPU is using the sleep modes (powertop might be one
tool for that) and running in the low frequencies when idle, just to be sure;
afterwards I'll forward this to the hp-wmi maintainer

it seems that enabling Power save mode triggers that high temp. on wifi module:

mt7925_phy0-pci-6200
Adapter: PCI adapter
temp1:        +70.0°C 

mt7925_phy0-pci-6200
Adapter: PCI adapter
temp1:        +79.0°C

mt7925_phy0-pci-6200
Adapter: PCI adapter
temp1:        +82.0°C

Please really try once with blacklisting the wifi module. It seems this is
reproducible easily for you, so maybe a few minutes without wifi should suffice
to detect if that makes a difference.

I'll roll back to 7.0.10 first to see if it is different. Will do that now...

Unfortunately wifi module temp is not reported in 7.0 tree, other temps. seems
to be in line with 7.1 measurements. But FAN is not starting so often like is
doing in 7.1 tree. Will try to blacklist wifi driver after the work, but it
will not be real test, because my work (load) is based on online work an I'll
be offline than.

OK, temperature reading from wifi module is implemented, but bugy, it is
reporting actual temp only after some/random  reloading  not after every
reading. 

mt7925_phy0-pci-6200
Adapter: PCI adapter
temp1:        +43.0°C 

mt7925_phy0-pci-6200
Adapter: PCI adapter
temp1:        +45.0°C  

When value it is displayed, it shows much lower temp. than on 7.1 tree, IDK if
it is reliable reading now with this erratical behavior.

I've tried with mt76 module blacklisted. Hard to compare, but FAN started to
spin with cpu temp 41 deg.C and no load, only system booted and terminal
opened.
