OK...Here's the scoop.
My rig is in the basement....a bit chilly down there.
At start, the heat sink is 53, the top of the cabinet is 54, and so is the speaker grille.

After an hour of receiving, the cabinet top is 68, the speaker is 64 (both still feel cold) and the heat sink is 86. So, to the touch...the heat sink feels room temperature to slightly above.
I have one of those IR non contact jobs to measure the temp.
Hope that helps.
....Dave

Thank you Dave. I think it does get hot just on receive only. I will try it 
that way for a while this afternoon. If you could do the same and tell me what 
you find I would appreciate it.

What happens on receive only?
I can turn my OMNI VI Plus on, let it sit for a while and see how hot it gets 
if that will help.
