It sounds like your laptop is working pretty much as it should. ACPI
controls both fan speed and CPU throttling based on several factors,
such as load and heat. How well ACPI works on your laptop depends very
much on how recent the software controlling it is. Generally, the more
recent the kernel, the better ACPI works - assuming your laptop is
supported (doing
cat /proc/acpi/info may give some clues).
Are you referring to the "obvious" options in the BIOS such as shut-down
temps? or are these functions that are just built into the ACPI that take
care of things without any obvious front-end?
ANYWAY... My laptop works just fine in Windows, but in Mepis it starts

But is the CPU running at full speed?
Dunno, but it sure seems doggedly slow. And some apps like kicker that take
up about 3% normally, seem to be taking up about 30% at that point...

Maybe the thermal trip points need to be tweaked. Maybe that's what
Athcool is doing; or is it just running the fan faster/more? At the risk
of being insulting, are you keeping all the fan ducts clear when you are
using the laptop?
From what I read on athcool, it's simply allowing the cpu to idle down or
some such thing during idle periods. Whereas without it, it's basically
running full-on all the time. (at least in linux)
Even with it on, I never hear the fan slow down like it does in Windows...
Is it possible I'm somehow more stressing the cpu and it's overheating and

Abnormal memory usage is another animal altogether.
