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.
