You can see my Chugger Pump Enclosure 1.0 HERE.
There were various problems with it.
1. The pump got pretty hot relatively quickly. A warning PeteNMA gave me. I don't mind eating crow. He was right.

Well...all that just wouldn't do. So I bought two things to fix my problem. First, a bigger box for greater stability and better air flow. Second, an AC fan. This should solve the heat problems.
So here you go. My Chugger Pump Enclosure 2.0. It is extremely stable. And the fan keeps it nice and cool. I wired it up so one switch controls the fan and another the pump. I have it wired so that the fan can run by itself, but the pump can't. For the pump to run, the fan must be on. This way I can turn the pump off, but keep the fan running to continue to cool the pump down.
