Well, there really isn't such a thing as too much flow to allow for good heat transfer. I think you mean efficient heat transfer. Faster flow will always cool faster than slower flow if the input water temp is a constant. When using a pump like you intend, the faster the flow the better, although there are diminishing returns when the flow gets to a certain point. The more important thing is to get the wort moving around the coils by stirring the pot.
