There is not much high pressure on the tail grill area.

I've pretty much settled on a pull type fan (installed under the IC) to augment the current 'one-way air direction' setup I currently have.

The engine fan draws air in from many locations. Engine side skirts, back skirt, lid join area, etc. 'Leaks' if you will. Theoretically the engine fan - if (somehow) sealed so the draw is through the IC only - would be the best solution by far. Yet the above variables don't allow it.

My solution is different. A pull fan, drawing air down, mounted beneath the IC. Enhance what is already happening - AND can be quantified, back-to-back via on/off switch.
