But, and a big one at that is this, an electric fan setup will very, very, seldom come on. Only time mine ever comes on is when I sit at a stop light for a few minutes, or maybe in a drive thru window. Normal driving, it never runs. Unless you've ever had electric fans, you'd be amazed at how little we actually need a fan. So, as long as we are moving, this is no drag on the alternator, at all. So how can this rob power? Answer, it can't.

It's a no brainer to me.
