A very simple question. I have alot of separate components in a small wooden cabinet (glass doors in front, fiberboard back with a small hole for cable connections) upon which sits my TV (Polk MSDS1 home theater, Sony Digital Cable box, Sony DVD, Sony VCR, NAD CD player and Tape player) When I open the doors, its a bit warmer in there. Is that an issue?

    Odds are yes, it can be a big problem.

    If i were you I would remove the glass door(s) and maybe even remove some of the backing.

    Heat build up can reduce the life of your components quite a bit as well as reduce the overall performance.

    I agree with phuz, heat is a problem. Try leaving the glass doors open when using your gear and remove all of the backing. Just remember to dust from time to time as that can be a problem too.

    I have a similar setup. I have kids, so I cannot leave the doors in the front open, but I did remove most of the backing. I made sure that the opening in the backing was at least 2 inches higher then the equipment on top. I also installed a fan controlled by a thermostat. When the temperature inside the cabinet reaches about 87 degrees the fan will turn on. I have a vent from the fan that leads down to the floor so cooler air from the floor reaches the equipment area. I was concerned about dust from the floor being picked up and blown into the equipment area, so I put a filter on the vent. The fan has only come on a few times and that was during the hot days of summer.

    I like the idea of the fan, could you tell me were you bought it and what type of fan it is. How does it work AC or DC, and how is it hooked up?

    Thanks

    ftelang, i have pretty much the same set-up you have with the entertainment center, it houses most of my components, some are just too big. when i put it together i did not even bother to put the flimsy backing on. it helps with air flow and it much easier to get at the back of stuff. i like to putter around a lot so that helps. took off the glass door too. i try and dust a couple of times a week. hope this helps

    regards,

    I drilled about a dozen 1" holes at the bottom and top in back of my entertainment center to create air flow, warm air rises bringing in cool air at the bottom. Has worked well so far.

    I bought a pc power supply and two case fans. I notice I have to dust off the receiver more often but I think its worth it. My Onkyo-800 tends to get pretty warm when driving my LSis.

    I am using a 4-inch fan. I purchased it at a local electronics store, do not get the one from radio shack it is too noisy. The thermostat I got from my dad who worked in the commercial refrigeration business, but you can get one at any HVAC supply store. I plugged it into a separate circuit then the rest of my gear so I would not get any humming. If you have any further questions please ask.

    if you are talking about slightly warmer - man forget about it, a few extra holes? maybe, but a fan, I would not.

    I mean hell your TV get warm right, well so will the receiver when it is working, and it being in the cabinet will "warm" the air inside of it.

    Now if you mean when I touch the rec. it is VERY warm or hot, then you have a problem.

    I do not recommend plugging into the receiver. The fan can create different frequencies and these noises can be passed on to the speakers.

    LOL! My receiver is in a cabnet. I use two high powered fans on top of it when I have to shut the door. The only problem is they are highly noisy.
    Damn you all, damn you all to hell.......
    I promised myself
    No more speakers. None. Nada. And then you posted this!!!!
