Many slot coolers blow just as much air as a medium speed fan. "They barely move any air" is 100% BS. However, the two slot fans I purchased at newegg around a year ago were piles of junk as far as construction goes. The molex connectors on both of them have since been destroyed through repeated plugging/unplugging. If you do decide to get one, be very gentle when plugging them in and unplugging them, the wires have a tendency to pull out of the molex.
