I suspect that what sort of driving you do is going to influence any fuel savings.. At highway speeds the fan is basically doing nothing but absorbing energy since the radiator gets an adequate flow of cooling air simply from the motion of the vehicle, so your fuel savings might be significant with an electric fan to replace the mechanical one.
If you are doing mostly stop and go type driving then the electric fan is going to be running a lot and will offset some of the potential fuel savings by putting a heavier load on the alternator.
