You can get them at the Pick and Pull cheap and they move incredible air. It is almost exactly the same size as the fan shroud on my 3.5. There is a proportional controller available that only runs the fan at the speed needed instead of on/off like most electric fans. You will need an upgraded alternator.

I hope to gain better cooling in traffic.
Eliminate fan noise when accelerating.
Control strategies would use existing temperature sensors and relays.
I would guess the change in energy consumption would be the added power for the alternator, but I do not know that for sure.

Tony H has covered an important point with respect to fan noise; a proportional, variable speed controller is required to minimize noise.
As to cooling, look first to the overall condition of the water system, and particularly to an area that is almost always overlooked: the water pump housing. The inside surface of the pump housing is shaped to match the shape of the blades of the pump impeller. Over time, the effects of corrosion/erosion will increase the clearance between the impeller and the housing, which increases the internal bypass/leakage. The leakage is a greater percentage of the nominal pump displacement at low pump speeds than at higher speeds. The usual case is that cooling system performance that is acceptable at highway speeds is rather poor at lower in-town speeds. Increased airflow may be of some help, but will not compensate for low water flow.
