I'm just finishing up on my very first Home Theater setup I've ever had and looking for possible semi cheap ideason cooling. Or even if its really needed. After finally winning the wife over to the fact one of these systems is ideal I've done the following. Syntax Kolin 37 inch LCD. Fed from a Scientific Atlanta HD3250. Also a Samsung HD-841 Onkyo TR-SX303 pumping its juice to 4 Polk Audio R-15's, one Polk Audio CS-200 center and a Accurian 125 watt sub. I'M LOVING IT. But the receiver does run fairly hot while the wife and kids are home and all most untouchable when they are not. Looking for some idea to help run this cooler. Samsung, HD box, receiver and the center all one over the other. Its 3 shelfs and the receiver is on the bottom with a 4 inch gap to the next shelf. The samsung is over it with the HD box on it also with a 4 inch shelf gap.Finally the center is on the upper shelf. All the shelfs are pulled forward leaving a 1+ inch gap on the rear to help allow air flow since the back is covered. I'm thing along the lines of a dual 3 inch fan about total length up to 17 inches mounted ontop of the receiver to pull air around. Idea sound?? Needed or not to worry?? Also havent had any luck finding a semi cheap 120 volt unit like such!!!! Ideas welcome!!!
