CPU temperature too high


Hello,

i installed gentoo and everything was ok within some days, temperature was about 44-45C.

i don't know if it does matter, but. then i downloaded drivers for intel graphics card and tried to installed, but it failed in DRM compilation. so i gave up.

since this time cpu temperature is too high, something about 55C. Does anyone know, what reason makes cpu overheating?

thank you
Mr_Zet

this is strange but i don't think 55 C is too high, especially for AMD

I have Celeron 2Ghz, and before it had 45C.

Now i found interesting thing, that the temperature is the same all time time. 56-57C when i do nothing, and the same temperature when i am compiling something.

That doesn't make sense, to me at least

Maybe lm_sensors do not read your temperature from BIOS well.

no. they are right, because air from fan is very hot.

i activated 'cpu frequency scaling' and now it works, back to 46C temperature.

i don't understand. it works, but in /proc/acpi/processor/throttling is set T0, it is maximum performance.

but the fact is that CPU was between 0-1%

as i was writing about 'cpu scaling', it doesn't work either...

but believe or not, when i activated SMP (multiprocessor support (i have only one)), and now it seems, that works.

here's a question for you... when you installed linux.. did you merely press 'enter' and the boot screen?

on laptops i use BOOT: linux26 acpi=on

and that will cause the cpu fan to turn on when your computer is on...

i was solving this situation almost a week, and i know, the problem isn't ACPI, it is problem of CPU.
because, CPU was heating and ACPI works fine, because regulates fan right.

So i recompiled kernel with SMP and now it works.
