So, I just replaced my TV cabinet with a new wooden one, and the ventilation is terrible, apparently. The situation is, I have a PS4 on the bottom, about 4 inches of clearance, then an A/V receiver on the top with another 4" of clearance above that. The back is solid wood, except for small cable holes. I'm considering these: http://www.newegg.com/Product/Produ...&cm_re=cabinet_fan-_-9SIA8J231W6983-_-Product As I can just pop them in the back and blow some air out. Think this would do the trick or should I commit to cutting holes in the back and installing 120 mm case fans?
