Connect gets pretty warm on top

I am a little surprised to hear that it works as well as you describe. I would have thought that the Connect plastic to the metal heat sink contact would not conduct much heat to the sink and would actually reduct the Connect surface available for heat radiation for an overall adverse impact.

But your measurements are proof to the contrary.

I have some really old ZP-80s, they have what looks like a metal Sonos badge inlay on the top but it might well be silver plastic.

I took my IR thermometer out when I saw this post, just as I removed the heat sink the ZP-80 was 87 degrees at the center of the badge area. After a half hour I checked it again and it was 93 so there is some difference from the heat sink, 6 degrees isn't much.

This is in an 80 degree room, old ZP, not playing music and the WiFi radio disabled. If it is playing, has the radio on or the room is warmer the heat sink may make a bigger difference.

Either way the ZP is not in danger of overheating.

As long as it is wired, I suggest you try disabling the wi-fi on your Connect, details in this link:

You will find that the heat output from the Connect reduces dramatically, and it will also use half the power that it otherwise would. It worked for me.

For anybody confused, there isn't a problem in this thread. There is no issue with the Connect running hot.
