Yeah, yeah, I know that there is not supposed to be any such thing as a "dumb question". But this one did give me pause; Do serpentine setups requiring a reverse flow water pump also use a fan with the blades angled the opposite direction? 
Makes sense but I do not have any laying around to compare to at the moment. Just wondering if anyone out there has ran into this before?
