The pusher fans on top will supply the majority of the air flow to the rear mount radiator and the hot air will exit through the diffuser.
Pardon my ignorance... I thought the whole idea of a rear diffuser was to create a low pressure area for better aerodynamics. Wouldn't it be better to take air from the diffuser area and push it up through the top?
