Hello again,
I tried Fedora release 25 and still the fan is on full blast. I messed with the BIOS and it didn’t help. I also booted up Archlinux that I have an SSD from the previous Librem 15 I had that I had to send back because the right hinge broke.
The good neews: The tweaks made (no more off switches under the screen) and the overall build quality has improved. So that is good. PureOS 2.1 is also more polished. Finally getting the hang of the package management of Debian.
The fan is quite annoying.
