Here's my .02 cents:

PRO's
1. Better cooling in traffic. Electric fans spin at a constant speed regardless of engine speed. Itís able to pull more air in at idle when in traffic.
2. More power to the rear wheels and better engine efficiency (Fuel Economy). Because the engine is not turning the fan and clutch assembly your engine will put more power to the wheels especially at higher rpm and not needlessly turn the fan at cruising speeds.
CON's
1. Overloading the alternator/electrical system. Relays burn out and some systems have no warning that the fans not turning.
2. Overheating - Improper cooling due to the lack of proper size and fitting of fan. Have to create or adapt a shroud, trial and error as we don't have aftermarket supporters.
