Actually, a friend of mine did a thesis on this kind of problem, related to babies dieing in hot cars (that, and normal people not likind hot cars). He found that an intake fan alone made very little difference to the temperature of the car, and that an exhaust fan alone was little better. But he managed to get the temperatures way, way down (to the same as the outdoor air temperature) with one of each.
