If the fans were running while you are on the highway they can actually block the air flow.

I ran that experiment several years ago. While cruising the highways around Dallas on a hot summer day I would cycle the fans on and off. The temp went up with the fans on at 65 mph.

We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
