Hi all,

The system does not show fans working for AMD GPU. I have tried many things and stuck now. I have read this topic as well Sensors-detect no fans

  1. sensors shows:

I have installed LACT and it shows 0 RPM

I tried to install GitHub - johnfanv2/LenovoLegionLinux: Driver and tools for controlling Lenovo Legion laptops in Linux including fan control and power mode., the build fails, so I tried installing packages:

I am not sure if I installed too much of this or what to do next. But if I try to run games or do video editing the temperatures goes high

But legion_hwmon-isa-0000 sensors started showing after I installed LenovoLegionLinux packages.

Before I got:

And you can hear the fan spinning? It’s just that rpm shows 0?

I’d report a bug upstream, probably here: https://gitlab.freedesktop.org/drm/amd
