   One of the hardware guys at work brought in a pentium hypercooler.
A fan on top of what looks like mini-refrigeration equipment. We
turned it upside down, and put a few drops of water on the solid
surface of it. It was ice in a minute or so. :)    [However, with
a normal fan, my P90 runs merely warm to the touch, so I don't have
one of those.]

   Try that in a GS. Be sure you have a buggie power supply; I bet
that thing eats some good chunks of power. :)

   Try the touch test-- the hotest chip is most likely the problem.
