No different than with a transmission cooler, especially a fan cooled
external one.

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.
On another note, you will need as much air movement to cool the radiator
as
you would need to cool the tube directly. With oil cooling you are only
moving the heat from the tube to the radiator. You still have the same
amount of heat to transfer to the air.
Sure.
Although with the radiator the surface area to cool will be much larger
than
it is with air cooling the tube so the air velocity can be lower.
Exactly! Very much lower, and very very much quieter. I want to sit next
to my quiet amp - not my vacuum cleaner.
