compile into ram and have more compilation threads to compile simultaneously.
there are how-tos on how to set up inram compilation (faster than disk one) on
the gentoo wiki and in the forum. usually you just need to have
/var/tmp/portage
(assuming /var/tmp/portage is where portage compiles the packages) to
a tmpfs.
i've added some lines in /etc/conf.d/local.start to create a directory in /tmp
then give the own to portage and then to mount this directory over
/var/tmp/portage and the unmount of this directory in local.stop when
closing the pc.
you'll have to set to the proper dimension to the tmpf inside
/etc/fstab. i have it set to
6.8 gb with 3.2gb of physical ram and 4 gb of swap space. remember
that the total ammount
of space for the particular tmpfs should not be over the space of
total physicalram plus
swap dimension or you'll have some problems with it.

you'll just have to try it out and monitor the thermal sensors after
you've added it. if
they have almost the same values that they had when using the original
cooler then
you should be able to safely substitute the base cooler. if you still
want a good cooler
i'd suggest cooler master or thermaltake coolers and dissipators that
are really great.
