Fan Control not working

[nitro122]

I’m not sure if this issue was mentioned before, but I couldn’t find a clear report matching this behavior.

Environment

• OS: Debian
• Kernel: Linux 6.12.90+deb13.1-amd64
• Laptop Model: Stealth 16Studio A13VG
• MControlCenter Version: 0.5.1

Issue

** Note other MControlCenter features appear to work correctly, including cooler boot and the application is installed and running normally.

Fan control is not working on my system. Changing fan settings in MControlCenter does not affect the actual fan speed.

Expected Behavior

When I set a manual fan speed or custom fan curve, the fans should respond and adjust accordingly.

Actual Behavior

• Fan control settings can be changed in the UI.
• No errors are shown.
• Fan speed does not change after applying settings.
• The system appears to remain on automatic fan control.

Steps To Reproduce

1. Open MControlCenter.
2. Navigate to the Fan Control section.
3. Set a manual fan speed or custom fan curve.
4. Apply the changes.
5. Observe that the fan speed remains unchanged.

Additional Information

I have also tried it on KDE the issue still remains
I can provide logs or any additional diagnostic information if needed.

@nitro122 okay, select High performance mode, and change the fan curve for the fan that you want then hit apply, wait a 5-7 seconds, and it should react accordingly

@mutchiko Hey thx again for replying so fast. I tried exactly what you told me. It's still not working for me. I waited for a 30sec. Here are some screenshot if it helps :) :

[nitro122]

these are the options I have on the terminal if it helps:

cat /sys/devices/platform/msi-ec/available_fan_modes

auto
silent
advanced 

I set it "advanced" still no change

echo advanced | sudo tee /sys/devices/platform/msi-ec/fan_mode

[mutchiko]

i see that it's the same ol' problem with debian and their weird way of handling ec_sys, notice how the fan speed is reported as zero, even though its probably spinning.

I have pinned an issue on the top: Debian 12/13 not supported

uninstall the current version and try the package in my comment , it should work. please report the result there
