I mounted the Triple 120mm Fan Cooling Kit with Thermal Controller vertically on rear of cabinet. Originally I had all fans blowing out, and because the front has a glass door the air draw from the front across the hot receiver was not enough to quickly cool down. I switched lowest fan to blow inward across the receiver from the rear, and the top two fans blowing out to create better circulation in the case. This did the trick. Now the fans turn on automatically and keep the receiver temp to just warm to the touch. Before it was hot to the touch. Within a few minutes after the receiver is powered off, the thermal sensor mounted over the top of the unit signals the fans to turn off. Perfect !
