I expect it to consume as close to zero power as possible. I agree 100%. If support comes back and tells me this is "normal", I'll probably sell the 976 (I'm just past the 30 day return) and go elsewhere. Have faith. IME Tech Support will want to check out your unit. I had several go-arounds (unknowingly) due to faulty house wiring. If yours has always idled hot... Tony

2" above my 976 is a shelf which contains a Mac mini and a network switch. I suppose I could re-locate those underneath the main cabinet and remove the shelf to see what temperature I would get on the 976 case. As a last resort, I could re-wire the fans so that one is on all the time, but that just seems wrong. In the other side of the cabinet, I have an Oppo DVD player and a Sony PS4 that generate zero heat when in standby.

Bryan, how are you measuring the temperature?
IMO, 2" is plenty of headspace. I have amps with less than that.

I've asked Bryan to let me know the temperature outside of his rack. If it is 115 degrees in standby, when not in an enclosure, something is definitely wrong and we will get him a new unit.

I taped the probe that came with my Fluke 87V to the top of the case.

As with most processor controlled powered on devices (those with standby power circuits) the 976 will supply about 5V to the microprocessor chip. The power transformer is only energized, when it's powered on by the processor.
Therefore, there should be no regulated voltage to result in heat radiation in standby. If you're experiencing this amount of heat in standby, definitely something wrong. My 976 measures about 95° when powered on, and cools off quite quickly within a couple of minutes.
I have it on a shelf with all open sides.

Ok, so I did some more investigating. I had never engaged the HDMI control settings before. So I turned them on.
With HDMI Pass Through turned on, the 976 generates as much heat as when in use, about 95° at the surface of the cover. This means the power transformer remains energized and the voltage regulators are active. This needs to be the case so the HDMI circuitry gets voltage so it can pass through the signal to the TV.
With only HDMI control turned on this isn't the case, as my 976 cools off relatively quickly.
Same for when neither settings are turned on.

Nice catch Helson! Ditto for me. With Pass through enabled, my 976 is 95 degrees in standby. After two hrs runtime, it did not get any hotter.

Yup. The temp is very steady in my set up too.

I pulled my 976 out of the cabinet this weekend and it measured 97 degrees in standby. I've replied to support in email and I will investigate turning off HDMI pass through.
