how to limit a CPU temperature?

[songbird <songbird@anthive.com>]

  i have a program that has changed it's behavior to suddenly
become a CPU hog (while doing something simple like uploading
files for my website).  probably a bug, but it got me to 
wondering how i could limit the CPU temperature to a range 
well below the maximum that kicks in by the CPU itself.

  i have an intel processor and it has the MAX which does
prevent it from going higher (100C), but i'd like to keep it
at 70C or lower.

  i've been trying to find anything that will let me set this
but no luck yet in my searches.

  thanks!  :)
