Here is an idea for all you cooling freaks. Try using the fans from a car air conditioning system. I'd try it but a lack of junkyards around here provents me for getting a cheap one. They run off a 12 volt system (the amps or watts I don't know). What I do know is that some are too large for most systems (around 6" just for the squirel cage), but their should be some that will work (try a camery, I think they might work). Just think about how much air one unit will push. And don't forget that they are quiet (no 50db fans here). Anyway this is just an idea for those cooling freaks that don't want water. And with tons of cars in junkyards I bet you'd find one that fits your needs. Good hunting
