Sorry, but you did ask for it...
In general, it is desirable to maximize the rate of flow through the
cooling system if the goal is to keep the engine as cool as possible.
Since the cooling system is a closed system (at least as it was
designed -- many LBCs don't quite cut the mustard in this respect...),
the rate of flow through the radiator and the engine must be the same,
or water must be exiting the system somewhere, or looping back around
into the radiator without passing through the engine. A greater flow
of water will tend to stabilize the temperature throughout the system,
minimizing hot, or cool spots, and bringing the entire system as near
to equilibrium as possible.
