My PC overheats

Post by dunome »

Hello !

I'm using LM 18.3, dual-booted with Windows 10, and I noticed that my Linux is overheating, compared to Windows 10.
When I do nothing, the t° is about 45-50°C, but when I use my PC : Chrome and stuff, it rises to 55-65° or even 70° when I watch a video.

And yet I use TLP, cpufreq, I disabled bluetooth...

Can't help, but just to let you know, it's tricky. I've tried all sorts of things that I've come across and no luck. My laptop runs hot when using Chrome also.

Code: Select all

Processes: 200 Uptime: 12 min
...i'm somewhat wondering...what are / why are all those processes running merely 12 minutes after booting?
Would be interested to also know why you've decided to not disclose your desktop, distro & kernel version in your inxi output (...cough-cough...) :lol:

Anyway - Mint 18.3 Mate, with some basic disabling of start-up items & a few unneeded services:Processes: 158 Uptime: 10h 37m
So that's probably the first thing to dig & take care of...
Secondly, if able, apply thermal paste - you might need to take it to the closer Acer service / computer repair shop for that.
That will give it a tremendous change, it's by far that from which you'll see the biggest difference.
You could buy a laptop cooler instead, but unless it's expensive, it won't have that much of an effect, and it's also annoying to carry along.
Last but not least, you could further undervolt it (but NOT underclock it - never do that), and see quite a bit of difference.

First off, I wouldn't automatically trust any of this measurement software as far as I can physically throw it. Nearly all measurements of anything and everything differ between Windows and Linux for who knows what reason, probably because they are measuring different internal components and may or may not be accurate in the first place.

Second off, you don't mention any a actual performance issues, such as slowdown or shutdown potentially due to overheating under either OS. (Overheating shutdown is a protective reaction, built into firmware.) Several years ago my Dell laptop was experiencing periodic sudden shutdowns that were not flagged by any heat measurement software, but the damn thing would just shut down. As a last resort before taking it in to a repair shop, I attached a narrow "crevice" tool to a strong shop vac and vacuum hosed out every opening in the unit short of actually disassembling it. That solved it, then and to this very day. So knock yourself out googling or, if there is something really wrong, consider physical dust and debris as a likely culprit before concluding it's something high tech.

TRUST BUT VERIFY any advice from anybody, including me. Mint/Ubuntu user since 10.04 LTS. LM20 64 bit XFCE (Dell 1520). Dual booting LM20 XFCE / Win7 (Lenovo desktop and Acer netbook).

Just thought i'd give you that link as it has some details of my experience with overheating under Mint and might give some tips on what to do and look for. I have no total solution as of yet but my post in the link gives some possible ideas that might help. Just be real careful of your system as if you leave the overheating issue unsolved it can kill your machine.
Laptop overheating? Check link here:itsfoss guide . A move from Cinnamon to XFCE can give a -5 to -10 degrees C change on overheating hardware.
