The alternator is going to produce a load on the engine as long is it is mechanically attached to the crank, only way to reduce that drag is to remove it (not advisable if you have a street driven car). The amount of resistance being produced by the alternator is also a constant, regardless of current is being drawn from the battery. So adding an electric fan will not produce more drag on the engine b/c the alternator is not a variable resistance unit, its either there or its not.
So yeah BS :P

Wow, you really have no idea about anything and you've proven it again.
Do you know how systems of energy work? You can't just take energy from the engine and not have it go anywhere.
Do me a favour and go get a hand driven generator. Hook up a lightbulb to the generator with a switch in line. Now turn the switch off. Crank the generator. While cranking the generator turn the switch on. Wow!! It just got harder to turn! Isn't that neat!?
Turns out energy can't be created or destroyed, so if your not producing as large of an electrical draw, it takes less force to turn your generator/alternator. This has to do with the 'magnetic feilds' but we'll save that one for a later lesson.
