They started using the electric fan with the front wheel drive cars. I have personally owned a 4th gen F-body and the logical reason they have an electrical fan is because the engine sits way back from the radiator.
The fan that was on the car in my previous example was one of the best at Summit. It had a shroud. Probably at least as good as the questioner is dealing with. I stick with my advice to eBay the POS electric fan and put the cooling system back as original.
