Stock fan clutch Vs Fidanza electric fans

[bryanf89]

about 5 months ago i bought a fidanza radiator and fan kit, the fans haven't given me any problems, until now. the fans go on and off at random times. i replaced the fuses twice, each time they were melted not blown. i replaced that with a high voltage screw in type fuse and its been good. now my relay is acting up, i replaced it with another one and its still a no go.

im contemplating about switching over to the stock fan clutch, my question is what difference will it make on the engine's HP and gas mileage? Would it be wise to put the clutch fan and leave one electric fan?

i thought to myself, the electric fans put load on the alternator to draw enough voltage to power them, but the clutch fan uses the engines mechanical energy to spin it, but the clutch fan is more reliable at this point.
