[gentoo-user] Summer laptop overheat

[gentoo-user] Summer laptop overheat

[Marko Kocić]

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

Try cleaning out the laptop vents with a can of compressed air - if
you're beyond warranty (or it won't void your warranty), then open up
all the covers on your laptop that you can, and get all the
dirt/dust/lint blown out that you can.

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.
