I remembered this link from the beta test program.

Here's Boom in environmental testing:

As Caleb pointed out at the time, they had access to and could have used a Logitech environmental test chamber, but this was quicker, cheaper and just as effective.

Suffice it to say you won't have heat problems with this thing - Boom can survive in an environment you can't (80 C = 176 F). So the plastic gets a little soft ;-) but it still keeps playing.

Oh and looking back at Caleb's comments, the plastic got to 90 C and the PCB well over 100 C.

Just a little amusing tidbit.

I took Boom out to the Delta a few weeks ago and ran it for 12+ hours in the hot baking sun. It was sitting on a lawn running at full volume about 100ft away from the WiFi signal. Though from another 40ft away, the remote didnt really work, everything else ran fine. It was easily over 100 degrees for a good portion of the day.

The Boom does have a built in sensor to shut it off eventually if its overheating, and I think we tripped that once. Putting a chair over it solved that ... but honestly, it was REALLY REALLY HOT that day. I was stunned at how well it worked...

Logitech does have a standard battery of environmental (temperature and humidity) tests (both for shipping/storage and operating) that we ran it through in addition to Caleb's run-it-til-it-melts test.

But we were all very concerned about heat in particular since this was the first product we had built with a built-in power amp!

By the way, the photo of 80C was before it really got hot. It was over 90
when I started peeling the thing apart. The board was well over 100C.

This was a brutality test to ensure that there was nothing about to fail at
our upper temperature limit of 40C.

We only spec (and reliability test to) +40C. I don't recommend putting it
in 90C environment.
