Look at the hardware sdk. It has alot of the technical specs which will be useful later on when designing circuits. One thing I saw is that the NXT has PWM (Pulse Width Modulation) so we can actually control the speed our fan runs at. So when looking for propulsion fan you might want to look at fans with the ability to control the speed with PWM (4pin PC fans will have this feature). Since we want our fans to go slow before the switch this is a simple way to control the speed of the propulsion fan with out having to go buy a speed controller.
