ventilation for these components

Violent31601 · 10-27-2009, 12:16 PM

I just bought a new stand that my PS3/Wii/DVR/Reciever go in, the problem is the back is enclosed (which I wanted to hide the wire), however i'm worried that the only ventilation in the back are little circle cutouts that the only purpose is to run wire through.

Should I cut out bigger holes, or would it probably be fine.

just a side not, the front is all exposed (they are not behind glass or anything.

Can you post a picture and give details about what will be in the rack?

i guess I could, didn't think pics were really needed, I was just asking if ventilation in the back was really needed if the front is all open and not behind glass or anything

I think it may matter how much room on top of the unit it is, and also some avr's and amps are known to run hot. They make items that help cool off an item if it's one of those. Also, some amps have fans built in, some don't...I think knowing specificially what's going in and how much room would help. I think having the front open will help though.

every system I listed above has a build in fan except the dvr

My Comcast Motorola 6412 DVR runs hot and it is "on" all the time even when in the "off" mode. With the back and sides closed on your "rack", and shelves extending from the front to the back, I think those small flat "pancake" fans would work well to assist the internal fans to move some air.

I asked a similar question in another forum, and someone made a good point. Heat is NEVER good for electronics. These machines will get warm, but the heat needs somewhere to go. In my case, the entire rack is open - front, sides, back, but the AVR I have is quite tight between the two shelves, so the top of the unit gets hot, and there is nowhere for it to go (Only about 1 inch of space on top of the unit). I am thinking of putting it on the top shelf to avoid this problem. That's why I was asking for a picture - ventilation doesn't just happen at the sides or back, but specifically with most AVR's, you also need a place at the top to relieve the heat.

Of all A/V equipment the receiver will always get the hottest because it does the most stuff. This is why it has vents everywhere on the top and sides. The receiver should really have nothing stacked on top of it so the heat can escape through the vents.

What I ended up doing was I cut out (with a knife) rectangle holes the size of the component in the back, therefor giving me easy access for hooking things up as well, simple solution to a simple problem in my mind.

So there I answered my own question
