My fan is not working after installation

neyzaak · February 16, 2026, 11:11am

I just installed Endeavor OS and it turns out my laptop fan isn’t working, and after I fiddled with it… the fan is working but isn’t detected, but the main problem is that the fan isn’t working optimally.
My laptop is OMEN 16 wd0xxx

First, welcome to the forum!

Second, you’ve posted no info on your system. See here how to properly include system info and logs.

neyzaak · February 16, 2026, 11:34am

i’ve posted it

UncleSpellbinder · February 16, 2026, 11:35am

You deleted it.

neyzaak · February 16, 2026, 11:36am

i make edit on my post

MichelN · February 16, 2026, 11:58am

What happens if you game ? Will the fans rises?

When i do light tasks the fans are running at lowest (igpu) and the nvidia card (dgpu) is turned off. When i game the fans are running perfectly fine.

Welcome to the community @neyzaak

That would seem to confirm the fan isn’t running. 50.0 C for your CPU is well within the ideal range, but, is it being throttled to achieve that?

Averaging, and currently running at 400MHz would seem to indicate it is being throttled

Have you had a look within your BIOS to see if you have some control there @neyzaak ?

neyzaak · February 17, 2026, 11:10am

no…i tried it but its not working like on th windows

neyzaak · February 17, 2026, 11:18am

i go to bios and the fan work in bios, but after i get in the OS the fan not work like in bios…like the power is very low

You may want to check these packages : hp-omen-wmi-dkms or hp-omen-gaming-wmi-dkms. Check their github pages if your actual model is supported, especially the second one may only work with the HP OMEN 16 (Board ID 8E35) which isn’t identical to your 8BA9 motherboard revision.

neyzaak · February 17, 2026, 12:18pm

and after that?

ricklinux · February 17, 2026, 12:56pm

Have you checked out the Arch Wiki? Not sure if anything is helpful.

neyzaak · February 17, 2026, 1:30pm

not a solution

ricklinux · February 17, 2026, 5:12pm

If your laptop fan wasn’t working I would think it would overheat!

MichelN · February 17, 2026, 6:51pm

Windows i resource hungry, linux is not. That’s the first thing i noticed under linux, how silence the fans where.

You can easely find if the fans are working or not under the information application and hit sensors

Bink · February 17, 2026, 9:37pm

Fan being low is ok, provided the workload is also low. Under normal circumstances, we would expect the fan to throttle up as the workload throttles up.

Let’s run a stress test to see if we can turn up the heat, and confirm whether those fans are working.

This will generate and encode 4K video content (colour test pattern) for 5 minutes:

ffmpeg -f lavfi -i testsrc=size=3840x2160:rate=30 -c:v libx265 -crf 23 -x265-params "num-pools=0:thread-input=1" -preset slow -t 300 ~/Desktop/cpu-stress-test.mkv

While its doing that, you can monitor CPU frequencies and temperatures. You can use inxi -Cs to do that repeatedly, but that’s a bit clunky. A better way would be to use a more visual tool, such as Sensors that @MichelN noted, or System Monitor, which can be configured to present graphs for CPU temperature, fan and frequency, giving you a visual sense of change over time.

Heads up too, that stress test will create the file cpu-stress-test.mkv in your Desktop directory. Feel free to delete that when done.

neyzaak · February 18, 2026, 5:15am

yes..of course

neyzaak · February 18, 2026, 5:17am

on me…the fan is not detected…its running but in the sensors, the RPM is zero

neyzaak · February 18, 2026, 5:20am

the stress test is can’t run on me, “the directory can’t opened”

Bink · February 18, 2026, 1:21pm

Try:

ffmpeg -f lavfi -i testsrc=size=3840x2160:rate=30 -c:v libx265 -crf 23 -x265-params "num-pools=0:thread-input=1" -preset slow -t 300 cpu-stress-test.mkv

That simply writes the file to whatever the current directory is.

For troubleshooting purposes, it would help us if you copy/paste the command you used and it’s full output, too, when it hasn’t worked.
