Fan control is not working on Dell Latitude 5580

I’m just trying Bazzite on a Dell Latitude 5580. But somehow the Fan control is broken after installing Bazzite. It sticks on the speed Bazzite boots on. So one time its on 2400rpm, next boot on 2800rpm.

I run ZorinOS before installing Bazzite and on Zorin it worked.

I installed fan-control, that can read the fan speed, but cannot control it. What could i do.

Somehow it’s working now… Strange…

And now its not working any more again. CPU Temp is 38° and fan runs at 2900 RPM
