Cooling has always been a serious problem for high-end CPUs. Cray was a better cooling system than CPU designer. When his cooling systems failed, the solder in the box melted. I'm pretty sure he was also the first person to build a liquid-cooled CPU - and he did it in commercial quantities. Watching the coolant drain from a 2 is a rather cool experience. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
