That would probably give you a casing temperature of around 36 degrees C.

Do we know where the TMP102 is situated? Presumably close to the amplifier chips. I normally find the CPU temp is lower than the TMP102 temp on the Amp.

I don’t know where it’s located, but both temperature readings are usually fairly similar when the device has been on for a few hours.

I think the only time I have seen the TMP102 temp lower than the CPU temp is when the Amp is first powered on or in standby. I assumed the amplifier chips produced most of the temperature rise and the CPU temp rose with the internal temperature.

Seems about right. At idle since last night at about 21 C mine says "temperature_cpu": "44", "temperature_tmp102": "36".

Of course now that I've been monitoring, I haven't seen it too unreasonably warm after a couple hours of usage: "temperature_power_control": "1000", "temperature_cpu": "49", "temperature_tmp102": "52". Ambient temperature at 25C. I'll continue to monitor.

On a side note, what does temperature_power_control reference? I noticed it's always at 1000 but I'm not even sure of what it is measuring/configuring or the units.
