Many AVS users like to use one of AC Infinity's Aircom fan models.It's not hot enough to burn, but, hotter than what I have felt with most all of my prior AV equipment. It definitely needs more ventilation as right now there is only about 2 inches of clearance on top. I was going to move it to a different area but I needed to buy some longer cables to connect to my amp. I guess I need to do that asap, at this point. For now, I'm going to make sure I use an external fan until I finalize a more permanent solution.
