However, i think it is still warm in there even when the receiver is not on. I thought about getting a very small fan to add more flow, perhaps connect it to the receiver so when it is on, the fan is running, etc. Maybe i'm worrying about something that doesn't matter but looking for suggestions on fans and things some of you have done to combat heat buildup. thx
I don't think I would hook up the fan to the receiver. Might develop noise that you don't want. Heat is electronics worst enemy. I have some of my gear behind double glass doors, but the equipment that runs hot to begin with, I have on a shelf out in the open, not behind glass doors. My processor is on an open shelf. My Directv set top box is also open. My five channel amp is on the bottom shelf of a tall wood entertainment center behind double wood doors. I always open both wood doors while the system is on, to dissipate the heat from the amp. Not too much room on the sides, but about one foot of overhead clearance is there. If you have everything inside the enclosed with no ventilation, you are asking for trouble. Some people configure two fans- one blowing fresh air in on the bottom of the rack, and one blowing the heat out the top. Of course you are now going to have to deal with "minor" fan noise. Depends one where the rack is located.
I drilled four inch holes along the rear of the shelves...maybe four each wood shelf. I can pass cables through the holes inside the cabinet, and the holes create natural convection to help out a little. If your glass doors are double doors- side by side, you can close one of them and open one of them just a little bit. But If your not going to use the fans, I would remove the hot equipment from the cabinet over to an open location.
