Best cooling electric fan

Sure, the original “Mopar cooling stuff” works great for a lot of applications.

Of course they also make millions of cars every year with electric fans. And a lot those cars make more horsepower and go a hell of a lot more miles than the old Mopar stuff did. You just have to put together a system that meets the requirements of your application, and that can be harder than just spending a bunch of money.

People have a strange desire to try reinventing the wheel. I'm a 7X Long Hauler on the Power Tour...and have found that the fancier the cooling system looks, the hotter the car usually runs. Three electric fans and a $1200 custom radiator? He's the guy with the hood open 4" and the heater blasting in 90-degree temperatures to not boil over in traffic.

Car manufacturers will happily spend $10+ million on cooling system R&D to eliminate a clutch fan for an extra 0.1MPG (or to save $1 on each car built) in the EPA tests. Most people have neither the money nor the desire to put that level of effort into it.

I wish I remember who said it, but one thing that has served me well with cooling systems: the factory engineers knew what they were doing. Start there.
