As a point of interest, "as fast as possible" isn't always correct, though
it may be WRT practical case-cooling considerations. One consideration in
designing race cars, especially those using stock engines, is to not
overdrive the water pump at high rpms. Not because of cavitation, because
you can flow water through the engine faster than is optimal for heat
dissipation. Non intuitive, but true - has to do with the heat transfer
across the water/metal surfaces and is otherwise over my head. ;)
