I don't currently have a heat gun(thinking of getting a cheap one)
I realize current receivers have DSP and other chips that makes them possibly run warmer.
I’m wondering if there are processors that run cooler than the Denon I have. Anyone find a solution to this problem.
There are quite a few solutions. The easiest is to get air flow through your cabinet. You need a fan system that will pull in cool air from the outside and remove the hot air. Also your 2" clearance is probably not enough to allow the heat to flow out. The AVR is probably recirculating hot air.
You have to ensure that the fan is not just pulling in cool air from a side vent and not removing the heat. typically you want one open area from somewhere in the front of the cabinet to allow cool air to flow over the AVR through the rear cabinet fan so that the hot air is removed. Air will take the path of least resistance so you may need to actually plug some of the side vents if you go to an active cooling solution. Place the fan at the back of the cabinet as high on the back panel as possible. This can also be accomplished on the side of the cabinet but it might be more difficult.
My Datasat LS10 is the coolest running processor I have ever owned. As previously mentioned it is pricey.
I just purchased a Marantz 8805 processor and it is pretty cool as well.
Usually heat comes from the amplifiers and from the HDMI board on AVR. The newer HDMI boards seem to run a lot cooler than those of 5-7 years ago.
Your AVR will likely still produce quite a bit of heat from the amplifier units and potentially from the HDMI board. I would look at active cooling solutions from AC infinity and also add fans to remove air from your cabinet
. There are also very quiet fans designed for PC cabinets such as Noctua.
I built a fan system with an auto turn on sensor using Noctua fans and it was very quiet depending on the rpm I set. The fans will produce some noise so you will need to test this to see if it bothers you.
