You will be amazed at how much heat is generated by those pumps! They almost last forever if you keepthem cool, but will cook themselves in a matter of days in close, unventilated quarters!

I used 4"x14" heating vents from Home Depot with a strip of screening material to keep bugs out. I also made some deflector sheilds on the inside of my cabinet to direct the flow into the fans and out of the body to increase motor cooling.
