CPU temperature and new kernel
 

I find that with 3.0.0-12-generic my cpu temperatures are noticeably higher
(5-10 degrees) than with 2.6.38-10.

Anyone else notice this?

- Richard.

Temps with that kernel are pretty much the same, ~ 39 - 40 C. AMD
Phenom X6 1075 cpu. AMD cool & quiet is turned on in BIOS, so it scales
back nicely when not being flogged.

I think I do notice more cpu activity, but can't quantify.

Phoronix has been going on for a while about power regressions in the
3.0 series kernels: e.g.
http://www.phoronix.com/scan.php?page=article&item=linux_31_power_regress& num=1

We don't have any Intel machines running the newer kernels yet.

CPU temperature and new kernel
 

I have an Intel i3 390M machine and the new gnome -- Ubuntu 11.10. I
think the temperature is with 6 degrees higher than the normal value:

It's clearly not a manufacturer's issue then. My cpu is AMD Phenom2 x4 3.0

Don't have grafics and date to compare with the old one. Didn't
anticipated this problem.
if some one uses still old gnome please put us a link with a screenshot
of psensors.
My screenshot it is at 50% load of processor becouse I'm running BOINC 6
of 7 days.
On Intel product page it is written that my CPU resist at 95 degrees
max. I puted the allarm at 72 degrees. BUT I think with the new software
and the new processors this will be a major problem in the next perioud
of time. SOLUTION: water cooling -- aprox. 200 euro. I'm wondering did
they do that at command -- to match in every laptop.

What solution do you have ?
