We are evaluating various enclosures for our residential deployment and have been shown a few "sealed" enclosures (no venting).
The question has arisen about heat buildup inside the boxes. To test this variable we ran an AP-125 inside one of the sealed enclosures for t he weekend. The AP appeared "cool".
We'd like to know if there is a way to pull the actual temperature of a connected AP?
We have a few applications where there are splash conditions (the monkey house and bus garage to name a few) and a sealed enclosure would be helpful there. For the res halls we could drill vent holes but want to know if this is absolutely necessary before drilling literally thousands of holes..
Thanks for all your help!

We put the enclosure in a network closet, which is typically warmer than the adjacent rooms due to the switches (Cisco switches are, above all else, VERY good at heating a room!). We let it bake for about three days.
What we found was that the temp remained below 38 degrees Celsius, well within tolerances for the AP-125.
The AP was active but not in a production profile, so no clients, and it was only reportedly drawing 9.8 Watts on a POE+ midspan (expected it to draw more).
More tests would be need under heavy load but so far we are feeling good about using the sealed enclosures in the res halls.
