My Home Theater Gear Setup (as follows) works great for me, but the equpment is in a fairly enclosed space and I don't want the equip to get too warm. So, I'd like to install one or more fans in the back wall of each rack that are SILENT to cool it down. I could have them pulling air out or pushing it in, but I think pulling it out would probably be best. I guess I could hook it up to X-10 control, but maybe I could do something with a thermostat (a later thought). Obviously this is in the living room and we're talking sound system, so fan noise is a major concern. I could go with large or small fan(s), but of course a narrow depth (less than 2-3") would be ideal as I plan to surface mount it/them on the outside of back wall(s). Does anyone have any thoughts? Thanks!
