The primary reason the auto industry went to electric fans is because most newer cars have the engine mounted sideways. They also use e-fans in vehicles with the engines mounted front to back because it would be more expensive to manufacture multiple different cooling systems.

That said; there are applications where e-fans are superior performers, particularly when a vehicle spends a lot of time at idle as they are not dependent on engine speed or vehicle velocity.

What they will not do is give you an HP advantage. Converting torque to electricity and back to torque is inherently less efficient than transferring torque.

Most people make the conversion for style though anyway.
