So maximum cooling occurs at zero flow? g

No, maximum heat transfer occurs. You then have to get that hot water
out to cool it and recycle it back to the engine. Look at the top/
bottom of a radiator. Many small, restricted openings to the cooling
tubes.

Been too long since the college physics class.
