Wait a minute there sparky, who said anything about the same fan? Now you're into a different discussion, one about blade design and how they're only efficient in one direction. I ASSumed a proper blade for either direction of flow, because (duh) anybody with a brain knows you can't reverse polarity on a puller and get reasonable results.So, assuming a proper fan in both configurations, you still say a pusher is less efficient than a puller (by a non trivial margin)?
