Comment 85 for bug 1602888

@d-bob-1 and @Peter

Well, you are right!

I omitted to say that I returned at the beginning of the year a Dell 7559 (with Win10) after only 24 hours of use!!!
The reason was that, after I made an video driver update for nvidia gc, video was suddenly freeze watching on youtube !!!, and fans went crazy. It was also posting a message like NVIDIA Windows Kernel Mode Driver stopped responding - bla bla
Ofcourse, Dell utilities were saying that everything is ok.
With Nvidia driver disabled, running only on Intel HD Graphics, everything was ok.
My assumption was that they put on the market an insufficiently tested model in terms of interaction between Intel HD graphics and Nvidia video platforms, but this is not all.

Regarding my Vostro 3568 (Ubuntu 16.04), with only Intel HDG 620, sensors command output:

with a lot of tasks running.

After couple of minutes, with same tasks running:

Adapter: Virtual device
temp1: +25.0°C (crit = +107.0°C)

coretemp-isa-0000

Core 1: +34.0°C (high = +100.0°C, crit = +100.0°C)

It looks like Dell and Intel joined hands for a processor warming prevention policy. Unfortunately dell use loud (cheap?:))fans.

I have the latest bios installed, also the Kabylake GT video driver and i'm Using Intel microcode firmware under Additional drivers.
