Sometimes, the machine runs hot because the hardware just _is_ that way.
Let's be optimistic, and assume not.

Hmm, the problem is, I keep forgetting where all this stuff is.  One 
place I look to refresh my memory is ThinkWiki, e.g., on 
Stuff linked from there:

...explains how to vary the CPU frequency on the fly.  (Running the CPU
at a lower clock rate makes it cooler.)

talks about HD power management, including the spindown feature made
briefly infamous by the aforementioned Ubuntu hoo-hah.

covers varying graphics chip frequency on the fly, with effects like
those of doing the same thing for your CPU(s).

has a bunch of miscellaneous tips to reduce power draw.

Also, the Gentoo guys (as usual) have some really good documentation on
the subject:  http://www.gentoo.org/doc/en/power-management-guide.xml
