A too common forgot is for cooling fins, in Air Cooled engines, or for the Radiator, in Liquid Cooled engines, Blown Air works much better than Aspirated Air, the usual approach with a belt driven fan.
Electric fans in front of Radiator, thermostat controlled, became standard in many cars.
But an electric engine costs money.
With a hole in center of Radiator, leaving room for a shaft moving the fan in front of Radiator, you could probably have improvements in engine cooling, and a lower power taken from engine by the fan.
A fan turning behind Radiator works on hot, less dense air, thus its efficiency is lower; a fan in front of Radiator has advantages, and is not necessarily more costly or failure prone.
Someone willing to test this?
