Which would be the better way to mount a cooling fan for my receiver? It is enclosed in a ET center. Would it be better to have it blowing across the top of the receiver or blowing out the back of the cabinet to get the hot air out? I thought it would be better to have it blowing on the receiver not directly into it or out the back becuse it don't get that hot in the cabinet just the receiver get hot. Another question how do you hook on of the little fans up. I want one of the Radio Shack or Parts Express fans but not sure how to plug them in to work. Thanks in advance.
