I recall something about liquid (something, could be nitrogen, or perhaps even mercury) that was chilled; PC Boards were then submersed in the liquid to keep cool.
Maybe on Crays?
Flourinert. very odd Lime green transparent liquid. in our cray, it was in a tank with a toilet float to keep the fluid topped up. the pipe bend radii for the cray fluid was *more* than the IBM waterpipes. our floor was raised to meet IBM. we had to sweat blood to get the cray in because of a 10-12mil difference. :-( the 400hz voltage genset was deeply scary. circuit breakers that smoke when they blow, fuzes like those in 'bil(l) the galactic hero' -George
