An engine driven fan, especially one with a thermostatic clutch that only pulls a high volume of air when it's needed, is far superior to any kind of electric cooling fan. The only reason I can think of for an electric fan is in a front wheel drive vehicle with a crosswise-mounted engine where the crankshaft and the radiator are not in the same plane.
