All this Aircom talk reminded me I wanted something to keep things cool.
My old TV furniture was open with plenty of airflow. Now the AVR is in and area that is closed on all sides except the front, and maybe the large hole in the back for the cables.
Read some reviews about Aircom and how some airflow products actually made the heat worse, as they didnt circulate properly.
Anyway, plan is to maybe install fans on the back side, that way any heat is pulled out.
Currently running the AVR at my typical volume so I can measure heat inside that area.
Ambient is 66F, current temp at 10 minutes is 70F. It it keeps like this, I may not need much cooling after all.
