I've heard the same from someone who spent 5 years working high up in
the Apple stress testing lab.  Basically he said to monitor the temps
and note the _change_ in temp, not so much the actual reading.  Make a
note of the "normal" temp during idle at normal operating air temp.
Watch temp changes over stress loading to determine the "normal"
changes you get.  If the machine goes beyond that temp, whatever the
reading, it's on the way to overheating.
