So I noticed something this weekend while diagnosing RAM troubles: the SystemSaver IIGS is very *very* effective at cooling down the machine. I was leaving the GS to do endless RAM tests, first with the case closed. When I'd open it up, I'd be surprised the power supply was actually cool to the touch, as were the other cards. As the troubleshooting continued, I'd just leave the GS opened up and running its memory tests. Guess what? The power supply was very warm to the touch, and there were areas that were almost hot. The cards were all very warm too. I know in the past there had been debates over the effectiveness of the GS System Saver. Well there's no doubt in my mind about this any more.
On a completely different (but hot) piece of equipment, I have used a thin "laptop cooler" dual fan (about 5/16" thick!) on top of the equipment to exhaust hot air from the top of the case. Even though the fans are very slow (and quiet) and don't move much air volume, removing the hot air from the top of the case dropped the temperature of the electronics by 20 degrees F! Exhausting the hottest air from the top of a case is extremely effective in removing heat, even if the air flow is modest. I think of it as "assisted convection" cooling. ;-) -michael NadaPong: Network game demo for Apple II computers!
