au contrare, mes amie!!! (forgive the spelling, but get the point)!
The whole issue of flow, heat transfer and mechanics is far too fluid
for me (forgive the pun)...but the list has already correctly pointed
out that there is a point beyond which increasing rate of flow has a
negative effect on heat transfer...and therefore cooling...making the
comments below (forgive the bluntness) wrong!

I shant flagilate you on this, as others already have. <g>
Think of this, in the stinking hot summer days, do you put cardboard in
front of the radiator to prevent the air from flowing through the
radiator too fast and causing overheating? No, of course not. You want
as much air through the radiator as possible, so that it can transfer as
much of the heat as possible.
Air is a fluid, water is a fluid. You want them both moving as quickly
as possible. In fact, if you can move them rapidly enough, you can
reduce the size of your radiator. Get it going fast enough, and you
theoretically could use a radiator the size of a postage stamp.
