Ok, so I found a good deal on an Onkyo 875 and took the plunge. I have it out in the open -- I'm using a Sanus stand for my tv and components. However, the heat still concerns me. From previous discussions there seem to be a lot of fan options. Was wondering if anyone could point me toward the better choices? Also, is it possible (for a newbie) to rig the fan so that it only comes on when the power is on? Any advice would be appreciated!
