I had to boot legacy mode, system will not work in UEFI.
Fan issue specific to the model: heat sensor triggers the fan even on light load and reboots the PC occasionally. Simple apps like webcam or browser can lead to this. Doesn't happen in Chromium OS or Win 10.
- I've changed the settings in BIOS, fan operation to silent, CPU TurboBoost (or whatever they called it, I'm not sure) off.

It still happens but on rare occasions and the fan noise is much less in general.

Have you tried running:
Code: [Select]
sudo sensors-detect
and answering Y to all questions .. then rebooting

Not sure it'll help, but can't hurt.

I have not, thanks for the advice.
I'm just testing it. Not sure how it affects the sensors as I see the fan fluctuating in speed, I'll try to get it to heat up and see if it reboots.

Didn't work, though it held up longer than previously.
Any idea how could I disable these faulty heat sensors?

Are you sure they're faulty, and it's not just the fans/heatsink fins are clogged ?
(or that you're not blocking the fan intake/exhaust ?)

I checked the fan and the passive cooler. I couldn't determine where the heat sensor is on the MB (it's not discrete like on the bigger models) but it all seems fine.
PC does get hot under load and the fan goes to highest RPM, gets pretty loud, but I find it hard to believe that simple webcam feed in gucview is so demanding that it causes the overheating after a cpulpe of minutes.
If it does, it must be something with the drivers?
