I've just installed the mint 19 cinnamon on my acer aspire 5830TG as a second OS alongside with win7 and immediately have a very high temp readings:

$ sensors
Adapter: ISA adapter
Package id 0:  +87.0°C  (high = +86.0°C, crit = +100.0°C)
Core 0:        +76.0°C  (high = +86.0°C, crit = +100.0°C)
Core 1:        +87.0°C  (high = +86.0°C, crit = +100.0°C)

with maxing out according to psensor CPU 93°C, GPU 72°C.

I only have a firefox running with 8 tabs opened. and a console. that's it.

I have already changed from xserver-xorg-video-nouveau to the recommended nvidia-driver-390 (the device is GeForce GT 540M)

It definitely doesn't look like that under the other OS, win7. I have to keep my palms in the air in order to write this and not to burn myself.

    When was the last time you cleaned the dust out of your laptop? – JShorthouse Apr 12 at 10:34
  • Not that long time ago.. about a year or so when I was changing the keyboard and upgrading RAM. Plus, as I mentioned win7 doesn't behave this way, otherwise both OSs would be affected, wouldn't they? – mooor Apr 12 at 10:42

    What processes do you have running? Can you check htop and ensure there isn't a process using a high amount of CPU? – JShorthouse Apr 12 at 10:46
  • @GAD3R I've tried that already tuxtweaks.com/2008/08/how-to-control-fan-speeds-in-ubuntu but got stacked at this point: moor@blackstar:~$ sudo pwmconfig # pwmconfig revision 6243 (2014-03-20) ... /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed – mooor Apr 12 at 11:07
  • @JShorthouse I don't see anything wild going on there, just a couple of standard processes.. psensors shows max CPU load measured at 45% – mooor Apr 12 at 11:13

Check your CPU heatsink ! ! Mine has disengaged from the mounting brackets, same symptoms ! Replace by a good model, select from the cpu type.

  • in fact I haven't checked the condition of the cooling paste since I bought it new. It will be worth trying but why everything works fine on win7 having intellij, vmbox, db servers, app server, firefox with 1000 tabs and what not fired up still being able to rest my palms... – mooor Apr 12 at 11:22
  • you were right! the paste on the gpu was dried out, the cpu though was still fine, just replaced the paste everywhere and guess what: Package id 0: +41.0°C (high = +86.0°C, crit = +100.0°C) Core 0: +41.0°C (high = +86.0°C, crit = +100.0°C) Core 1: +40.0°C (high = +86.0°C, crit = +100.0°C) was hoping to go down to something like 23-25 °C but I can live with 40 ;) wondering why it was much colder on windows? Anyway thanks! – mooor Apr 12 at 13:51
  • Happy to know ! I do not think that Mint is more cpu hungry than other OS, so it can be the usage. My system is working at 75deg, but always doing tasks for BOINC (shared computational power), limiting to 80% cpu usage max. – Luc Apr 13 at 13:22
