Pardon my ignorance, but from my limited knowledge of thermodynamics, 
moving air provides cooling, static air does not.  So just because there 
is pressure and "some" moving air, that doesn't seem to necessarily cool 
it.  Direct air flow over a tube is a far better cooling solution than 
just air flow in an entire cabinet.

I would definitely add additional cooling fans to this unit if it was in 
my shack.
