My D2 has a good 7" above it, and is well ventilated. It's open in the back and perforated steel to the left, right, and front. My D2 feels barely warm to the touch.
For testing, I currently have the D2 sitting in the middle of the room, no cabinet, no other heat generating equipment. Open in every direction but sitting on a hard surface. The ambient temperature is 73 F. I do not have air conditioning in that room - not really needed as it very, very rarely approaches an ambient 80. (I am in Northern California, well insulated new house, no major sunlight incursion into the room.)
Even out in the open, the D2 still gets hot and eventually the setup video degrades. If I take an external household fan and direct it on the D2, it cools down to "cool to the touch" in a couple of minutes. Then the setup video returns. Unfortunately, it is not just the setup screen. Last night after watching an SD movie from SAT for 2+ hours the video processing on 480i started producing a jittery image. HD was OK. Again directing a fan on the unit, cured the problem.
This D2 seems more sensitive to heat than its 4 predecessors (when they worked). So I definitely do not think that Anthem has made any changes/inroads on the cooling issues.
I haven't checked it scientifically but suspect that when not doing video processing that the overheating problem is not as severe.
You say your D2 is "well ventilated". Do you have forced air or just relying on convection and ample space around it? Do you have space below the unit as well, I couldn't tell from your post. Mine is just sitting on its feet on a surface.
After 5 units, there is not much to say about the "quality" and design of this unit. It is clearly thermally challenged. Your experience may vary ... but the design is just not robust.
I will get a fan and hope that the unit stays operating. Probably one of the stackable kind, as recommended.
Holding the modern day record for returned D2's at 4, I will not be going for 5.
Clearly, I remain disappointed with this whole D2 saga. Anthem has listened to me all the way through and been responsive. They have even (apparently) changed the HDMI jacks based upon my recommendations and perhaps others. BTW, I have not had any problems with the new HDMI jacks - so that is a step in the right direction.
