Best Linux Mint application for stressing system to detect overheating of CPU

Post by wpshooter » Fri Feb 09, 2018 8:49 am

Which Linux Mint application would be the best to use to stress a Linux Mint OS
computer to see if the CPU on the computer is subject to overheating or is there
an application which just strictly measures the CPU temperature ?

Thanks.

Best application? Update manager :mrgreen: Try to install few kernels one by one in sequence. Very few things can make CPU more hot than this.
Windows assumes I'm stupid but Linux demands proof of it

I am thinking that you are exactly correct because when I updated a large number of updates that the
owner of this computer had not done for a long time and then afterwards when I booted the computer
shortly thereafter with a USB key which had an image of the 18.3 version of Linux Mint on it, there
where messages displayed during the booting to the USB that indicated that there was a problem
with the CPU temperature.

What about this CPUBURN application that I found, any harm in trying it to test if the CPU has a problem ?

Thanks.

Is that a Linux Mint application ? I did not see it in Synaptic. Thanks.

Probably converting videos, or a simple program that does lots of math.
or is there an application which just strictly measures the CPU temperature ?
Probably a lot of them - my conky line for CPU temp is

Code: Select all

${exec sensors -f | grep 'Core 0' | cut -c15-21 } ${exec sensors -f | grep 'Core 1' | cut -c15-21 }F
so

Code: Select all

sensors -f 
in a terminal, or

Code: Select all

watch sensors -f

What comes quickly into my mint: Converting a video (e. g. with VLC) from one format into another. The effect may differ, if the GPU can get used for that. If not this conversion will most likely take tremendous time (of course depending from the file size) and will bring the CPU to get hot. The target format might influence, how much the CPU has to do. Just found in the preview, that Flemur had the same idea.)

Running two instances of this little program pegged both my cores @100% cpu use:

Code: Select all

#include <stdio.h>
#include <math.h>
int main (ac,av)
int ac;
char **av;
{
   double x,y,z, rand();

   while (1)
   {
      x = rand();
      y = x*x;
   }
}
One instance used mostly one core....converting a video (and audio) with ffmpeg used about 90% CPU each core.

Prime95
+1 for Prime95
I think the only thing to make it more stressful on a system would be to run it in an OS/2 virtual machine ... if an OS/2 version of Prime95 was available and you found a way to install OS/2 in the first place.

You can also use 'stress', see here for example: https://www.hecticgeek.com/2012/11/stre ... th-stress/
kittykernel - a cat-friendly, custom kernel manager for Linux Mint and other Debian derivates. Take a look or two here: Releases Github

That's what I was thinking ... maybe convert one and watch an HEVC one at the same time.
