Correct!  The faster the oil flow in the tube cooler, the better the 
cooling.

But not so for the radiator.  The oil must slow down and be in the 
radiator for a finite time for the heat to be transferred from the oil 
to the air.

Sure.

Exactly!  Very much lower, and very very much quieter.  I want to sit 
next to my quiet amp - not my vacuum cleaner.
