Distributor ID: Ubuntu
Description:  Ubuntu 16.04.3 LTS
Release:  16.04
Codename: xenial

Linux test 4.13.0-32-generic #35~16.04.1-Ubuntu SMP Thu Jan 25 10:13:43 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Two weeks ago or so, temp started going abnormally high even when doing the simplest thing (web browsing). I've got myself diagnosed that the video chipset was working bad and it needed "reflow". I had the chance to try a new motherboard but even after trying it out, the behavior is the same.

I've collected some stats and the weird thing is that temp does never go below 60°C (can't show the graph now 'cuz I need more reputation). You can see it here.

I can see the same from the sensors output.

acpitz-virtual-0
Adapter: Virtual device
temp1:        +70.0°C  

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +68.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +68.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +65.0°C  (high = +100.0°C, crit = +100.0°C)

What worries me now is that even with a new motherboard I'm "getting" this high temp and the fans go crazy ...

I'm no expert but could this be due to a driver problem may be? My next guess is reinstalling ubuntu, but I want to get some info before going that way.

I've left the PC running on the BIOS and, from time to time, the fans do work, but I really do not know if that's a reasonable test.

Any hint is highly appreciated ...

thanks

Overheating is a big and well-known problem of HP notebooks. And the overheating is observed irrespective of the installed operating system. You can advise only to thoroughly purge the grille of the cooling system and change the thermal paste, preferably on liquid pro or Arctic Silver 5 or Arctic Cooling MX-4 (which is slightly worse). Read more about thermal paste:

Buy a stand for cooling + always look behind the left side of the laptop, so that nothing is nearby and does not block outflow of air
