[Bug 596923] [NEW] Asus F8Sg high CPU temperature

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Device is Asus F8Sg with new clear installation from UbuntuMinimalCD
(mini.iso). There is only base system installed (Ubuntu 10.04 Lucid Lynx-amd64), nothing else, except
some slim utilities like: mc, powertop, lm-sensors. So there is no xserver, kdm or something - just BASE.

To be short, showing next:

$ uname -a
Linux asusbook 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 19:31:57 UTC
2010 x86_64 GNU/Linux

$ cat /proc/cpuinfo | grep -i  intel
vendor_id       : GenuineIntel
model name      : Intel(R) Core(TM)2 Duo CPU     T8100  @ 2.10GHz
vendor_id       : GenuineIntel
model name      : Intel(R) Core(TM)2 Duo CPU     T8100  @ 2.10GHz

$ cat /proc/cpuinfo | grep -i Mhz
cpu MHz         : 800.000
cpu MHz         : 800.000

$ cat /home/vlad/top

Cpu(s):  0.1%us,  0.4%sy,  0.0%ni, 99.0%id,  0.6%wa,  0.0%hi,  0.0%si,  0.0%st

Swap:  2080408k total,        0k used,  2080408k free,    34552k cached

And the CPU Temperature is high opposite temperature on the notebook
with running XP or Debian Lenny. And as a result battery life depends
on this issue.
So lm-sensors when Ubuntu's running returns next:

$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:       +61.0  °C  (crit = +105.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +61.0 °C  (high = +105.0°C, crit = +105.0°C)

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +49.0 °C  (high = +105.0°C, crit = +105.0°C)

(And when Debian's running the temperature is 36-42 approx.)

$ sudo powertop

Tell me, please, where the trouble is?
