I finally put the doors on my entertainment center a couple weeks ago, finishing a project that I've been working on for 3 years (rather sporadically!). Anyway, I also decided to stick a thermometer on top of the receiver to check temperatures now that the airflow has changed. Yesterday, while watching a movie at reasonable levels (and not a big bombastic movie, either-A Mighty Wind), the thermometer, which is sitting on top of the reciever, read 120 degrees F. Should I consider sticking a fan in the entertainment center? I've got cutouts on the back for cables and cooling, but I am a little concerned. The reciever didn't show any ill effects, and neither did the DVD player sitting on the shelf above it.
