ShadetreeMech, regarding the MPG penalty for running the fan I will be doing a test on current draw vs MPG for my car when i finally find a good enough test site.

but from previous tests (that weren't ideal) i think there was only a few percent penalty for running with full head lights compared to parkers. I have the standard fillament lights not LED so the current draw of my head lights is probably comparable to the fan current draw.

So i wouldn't expect to see more than 2 or 3 percent for running a fan also the fan wont always be on.
