Hi,
I cannot help you with this, but I would recommend that you should
monitor closely and exactly, what is going on in regard to fan speed and
temperature.

Lm-sensors is handy for this. There is a nice frontend for KDE
(ksensors, I believe) and xsensors also works for non KDE desktops

regards and good luck
Eberhard
