Video - Horsepower Loss To Fans.....

I thought this was an interesting episode too. Then I thought, what happens when a vehicle is moving at a certain speed, 30-40 mph and above, then the air is being forced through the radiator and the fan doesn't have to 'work' to pull air through the radiator? Once there is neutral, and then positive pressure on the front side of the fan, I bet the power loss is MUCH less.
