best electric fan

Unsuccessful electric fan installations are pretty much always come down to

- undersized fans (regardless of how much money they cost!) or
- inadequate power supply

Just like the factory mechanical fans, you have to pick an electric fan that has the cooling capacity for your application. Lots of really expensive electric fans don't produce enough CFM to be stand alone fans on these cars. And then there's the cheap radiator and fan "kits" that don't even advertise how many CFM they're capable of.

And yeah, if your fan is big enough to move the CFM it's going to need to it will require more amps than the factory wiring system was designed for.
