I took the opposite tack: I put two computer case fans ziptied on the upper panel directing airflow outward, so that the convected air is blown out, and therefore cooler air can come in from below. Same end result, different technique. Yes, this means my upper panel is permanently wired in, but I left a lot of slack if I ever need to open it, so it's no big deal. Plus, I can always uncap the splice if necessary. It does work well, silent, and I can feel the warm air leaving the chamber when its on.

Thanks for the settings, I'm going to have to check mine. I think yours are a few degrees cooler than mine.
