Bottom should be intake, top should be exhaust (hot air rises, cold are sinks)
Also, you should just west-east, that way you do not pull hot air from the graphics cards.
Try to balance the air flow too. If you have 4 fans, try to have 2 intake and 2 exhaust if possible, but if it is not, lean towards exhaust, because exhaust fans can always force are into the case.
