Radiators also need the air to move at the right speed through them, too slow and the air isn't drawing the heat out enough, too fast and the air doesnt have a chance to absorb the heat to remove it.
Same with the coolant, fit a slow pump and the engine cooks before the coolant can cool it, too fast and it cooks because the coolant isn't having the heat drawn out of it in the radiator.
Unfortunately, this is a myth.
Faster for both is better for cooling. The reason is that heat transfers faster with a greater difference in temperature, and the best way to guarantee this is to flow the fluids through as fast as possible, keeping the mediums as far apart in temperature as possible. 'staying in the radiator longer' is an age old myth that just wont go away, and physics hasnt supported for centuries.
