A moot point once you drive with the AC on. I have often though of using a
sail switch to keep the fan off as the vehicle is traveling at speed. The
radiator fan is a huge electrical load and at 60 mph probably provides no
benefit whatsoever except to burn more fuel and heat up the alternator and
wiring.

How about that from Van Caf�? Something that automatically kicks the
radiator fan onto low speed when you're doing slow speeds.
