Check this out!!!Hopefully this system will work for all of us

I think all fans should be very well balanced. This one is no different from another. As far as the tubes they could just diverge...very very small head loss in even a 90 degree bend on such a small area of tubes given the total dimension..and one would need to consider the efficiency of the entire radiator which will likely exceed what one would need anyway provided they have a properly tuned engine. The slots on the inside that increase flow I'm not too sure about. It depends on how that air flow is diverted. It might not be good for warm air being pulled from the engine compartment and into the front of the fan. However they might channel that flow somehow that I didn't see in the pics. Without knowing much more detail looks like a good problem solver. I don't have a dog in the fight though..no electric fan if I can help it.
