There is a full shroud that is sealed to the radiator, but I never thought about the fan being off set as a problem. It had to go there to clear the pump. I should try some tests to see if I'm getting full flow through the radiator, but the fan moves a ton of air. Even so, the issue happens when the car is driving and the fan should have less affect on the cooling system. I think I'm just going to go back to the mechanical pump for piece of mind, if nothing else. Thanks for the input.
