Overheat problems with Lombard Powerbook

[p***@gmail.com]

I'm having crash problems when my Lombard powerbook (333 MHz) is going
hot.

Testing the problem, the dangerous temperature is aroun 75+ Celsius.
I'm obtainig the temperature data from /proc/cpuinfo file, and watching
it every few seconds. External fan don't help too much to solve this
problem, only delay them. Internal fan never goes on. When I use a
powerful external fan with keyboard removed for better performance, the
machine never crash in a procesor intensive test.

Is there a way with software to switch on the internal fan? I saw 1
PCMCIA circunvent, but I dont have tecnician skills nor tools.

Kernel 2.4.22-2g, YDL distribution.

I don't think this has to do much with YDL. It sounds like the cooling
assembly needs to be repaired or looked into as it ought to work
automagically. I have used YDL 4.0 on a G3 Pismo without issue. I am
currently using Ubuntu 4.10 and now 5.04 - without issue.

There are a number of places that know how to repair that stuff - a good
google search under "Powerbook repair" and "Powerbook first aid" should show
that - at least within North America.
