well, I just tested it: Running two cpuburn instances in parallel, the
temperature reaches 100=C2=B0C pretty fast. The system runs at ~102=C2=B0C =
for
maybe 10 or 20 seconds, before it shuts down. Just when it reaches 100=C2=
=B0
C, the fan speeds up to ~3600RPM, but it seems it cannot push down the
temperature fast enough again.

Is this fan speed behaviour normal or might there be something
misconfigured? As far as I know I left everything to BIOS controlled
(and the ibm_acpi module agrees:=20
cat /proc/acpi/ibm/fan
status:		enabled
speed:		2959
level:		auto
) so is there any other kind of setting that could affect it?

(I=E2=80=99m only using the internal graphics card, fixed in the BIOS, if t=
hat
makes a difference.)

Thanks,
Joachim
