Electric cooling fan?

[AggieDave]

A great mod to make to a water cooled vehicle is to ditch the fan and fan clutch and go with an electric fan mounted on the radiator. Many times its controled by a temp switch.

However, except for oil cooler setups, I've never really seen an electric fan setup to replace the doghouse fan setup. Has anyone tried this? I would think that it would take a significant load off a street engine and maybe be more efficient.
