Review on Advanced Programmable Cooling Kits For Cabinets, AV Components, And More (Dual 80Mm, Plastic) by Troy Caldwell

Purchased this for my entertainment center to keep an Onkyo TX-NR3009 cool. Fairly easy to install, once you get the holes cut. Programmable LED thermal controller can be set to come on and turn off at nearly any temp. Displays in Celsius and Fahrenheit. The dual 120mm fans are barely audible with the room completely silent. There is a small thermal probe that you can affix anywhere (I put mine right inside the grill on the receiver on top). Keeps my notoriously hot Onkyo receiver very cool. Temps are constant at 109 F (temp taken right inside receiver case) on full load. Very nice product and great quality.
