[Bug 57556] CPU and graphics card too much hot

[Daniel Sarac]

Public bug reported:

Binary package hint: linux-686-smp

My Hardware:
notebook, acer wlmi 5652 with Intel Centrion Duo  T2300  @ 1.66GHz Processor, a GeForce Go 7600 and so (loo a the acer website for more info)

The problem:
the CPU and the graphics are too hot ! ! !

When I am using kernel '2.6.15-26-386' all ist fine: CPU at a
temperature of 34 Celsius (cat /proc/acpi/thermal_zone/TZ00/temperature)
and graphics card also at normal level of temperature. Also my HDD is
ok: at 48 Celsius.

When I am using kernel '2.6.15-26-686' with support for SMP, the hardware is much more hot:
- the Processor from 34 up to 41-45 Celsius, after 1-2 hours at 50-52 Celsius !!!
-graohics card is 12-15 degrees hotter than without SMP support, that's too much !!!
- also the HDD is too hot: from 48 Celius a jump to 52-56 Celsius !!!


I have a dual-boot system with windowsXP, there the CPU has a temperature  about 32-34 and the HDD a temperature about 44-46 Celius.

This mean: the 2.6.15-26-386 seems to be ok, just 1-3 degree hotter than
under windowsXP. But the 2.6.15-26-686 kernel isn't ok. The Hardware os
too hot, what can make damage to the components.


I am a new ubuntu-user and I don't know what the problem could be ? Maybe the kernel 2.6.15-26-686 has a bad cooling- or fan-management. Maybe only new boundaries are need to be set, but I really don't know.

If much more information is needed, just ask (and explain how to get
this information) :)
