overheating only in Linux, kernels from 2.6.32 to 3.6

[acanfora]

Hello, I am experiencing huge overheating on a TP R60e 657WG with Linux Mint 13.
I tried the following kernels: 3.2, 3.4, 3.6, and then back to pre-2.6.38 kernel, I choose to try the 2.6.32.
I tried also to pass directives to kernel, like aspm=force and so on but... nothing, the CPU temperature still soars to 80° Celsius and beyond. Booting the same machine with Windows XP brings the CPU temperature back to 50° Celsius.
Do you have any experience/fix on this topic? From Phoronix is seems that is a peculiar problem of intel CPUs, see the graphs on these pages:

Since I absolutely need to have a laptop with Linux loaded, I am thinking to buy the TP Edge 535, since seems that AMD processors do not suffer from this problem, do you have any experience with Linux on that model?

Thank you in advance for the help you may give!

Is there anybody out there?

Hello and welcome to the forum.

I can't speak specifically to the Thinkpad Edge E535 nor to Linux Mint 13. However, I can speak specifically to the Thinkpad T410 and T420 which I've used extensively over the last few years with various versions of Ubuntu (very close to Mint), lately with version 12.04. I've never experienced any issues with overheating. Note that in both of those machines I had Intel integrated video only and no discrete graphics chip.

My current 12.04 Ubuntu implementation reports the use of kernel:

Code: Select all

uname -a
Linux steve-ThinkPad-T420 3.2.0-32-generic #51-Ubuntu SMP Wed Sep 26 21:33:09 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Not sure that answers your question specifically, but I am a linux user and with the above configurations, encountering no issues...

Thank you for sharing your experience. This problem is very weird, is puzzling me. I have a Core Duo cpu. Mint 13 has the same kernel as Ubuntu 12.04. I also tried other Ubuntu mainline kernels shipped after 12.04 without success. Since my processor does not support the x64 instruction set and I have only 1536 MB RAM, I chosen x86 kernels without PAE. Perhaps I might try a PAE kernel to see if there is any difference.
