Summer laptop overheat

Hi,

during this summer when temperatures are high, I noticed
that my
laptop often (almost always)  overheat when I try to emerge
some
larger package (gcc, glibc, kernel, ...)

This started happening some time ago, but was bearable until
now. Now
I can't compile almost anything, my laptop just switch off.

I tried lowering CPU frequency to avoid overheat, but with
no effect.

Is there some "magic" option to enable in order to
reduce heat?
How should I check that my fans are running properly under
gentoo?

This doesn't happen in windoze, on the same machine
(although I don't
do so heavy compiles there)

Thanks,
Marko

Be careful when blowing on the fans though.  I have been
known to mess
up the bearings in fans when blowing compressed air on 
them.  The way I
usually take care of this is to put something like a
toothpick in the
fan to keep it from turning.   That said, I use a air
compressor instead
of a can of air but still be careful and make sure the fans
are running
OK after you are done. 

Also, they do make those little things you can put on the
bottom that
will blow air across the bottom of the laptop.  That helps
too.  They
are not to expensive and they seem to plug into the USB port
for power
nowadays.

9 out of 10 times compressed air fixes this. I just
impressed my cousin 
last month with this $2.99 fix when he was looking for a
much more 
expensive and involved fix.
