Jon,
If it *were* in your shack, you would know how cool it actually runs and
would not have to hypothesize in the area of thermodynamics. I have
access to a "Vaneometer" made by Dwyer Instruments, which measures air
velocity in Ft./Min. When placed above each tube, outside the cabinet,
the relative air flow is nearly equal, irrespective of the internal fan
placement.
We now leave the pragmatic world and return the reflector to normal use.
