The problem is that I'm using a laptop but somehow (I don't know
exactly why) recently when I run some cpu-intensive and time consuming
programs it caused the cpu too hot and an automatic shutdown is
resulted.  I want to keep the CPU usage low for those programs to
avoid the forced shutdown.

In the mean while I'm also looking for an external CPU cooler. :)
