Pull fans under the IC, 110%. I've done all sorts of experimenting in this area.

The engine fan concept does a mediocre job AT BEST - the routes for air pulled into the fan are numerous - and cavernous (hey, it rhymed):

Sides & top of the engine lid: Huge areas for air to come on in, and it does
Sides of the engine: Despite the rubber side skirts, air flows on in, easily. And it isn't cool air.

Air leakage on a 930 engine compartment - fans take care of this.
