I have an Onkyo 5007 and the space it fits into has only 5/8" above it. What I did was buy a laptop pad cooler with 3 fans, removed the fans from the housing and they push air in. I bought another one with 2 fans and a front exhaust that pulls air out and exhausts it to the front of the Onkyo. I bought a 4 port usb hub and plugged it into the back of my att cable box. Works good and cannot hear it even with everything off. I found everything on ebay and spent maybe $30.
