Hello David,
however it seems the fan control does not work for me. The fan spins but at a low speed, and does not increase even if I run a stresstest like 'stress --cpu 4'.
Maybe you try to install tlp in dom0:

I am installing powertop and tlp on all my Linux Laptops.
In dom0:
sudo qubes-dom0-update tlp powertop
