| In my experience MD5 does seem to be a really good CPU heater.

Mine is:
	sh
	while :
	do
	done

and watch the temperature go up immediately.  In about 15 minutes or
less it will be at max.  I found this out by accident and wondered
one this one system kept crashing.  Some CPUs are more sensitive to
temperature then others.  Some heat sinks work better.
