LCD TV stand in cabinet/airflow advice please

[ekinskofer]

Hi all,

First off, I'm a first time poster. Great forums..

I just purchased a new sony bravia 46"" Z series.. love it so far. I need to build a stand for it though and put some components under it. The tv "hole" on my display wall sits next to the fireplace (which we don't use much). The hole is 44" high x 29" deep x 45" wide. Long story short.. after the stand is built, there will be roughly 2" of breathing room on each side of the tv.

My bro and I have devised a simple stand with some fans built in the back attached to a thermostat and I wanted to put it out there to see if anyone had issues with the design.

In the for holes, I will be putting a HD PVR, 360, old xbox, bravia sync audio receiver.

I am slightly concerned about the 360 as it's prone to overheating in confined spaces.. however, with the 120mm fans in the rear drawing air from the front, this might not be a problem.. We plan to use convection push the air out the 2" space at the top and sides of the tv. Optionally if it gets too hot and convection is not enough, we'll attach a fan to the top (ceiling) of the display cabinet to move the air forward.

What I am wondering is:
a) Will this provide enough ventillation for all my components and TV?
b) Will convection work with the design? if not will the fan at the top?
c) Is this safe with my 360? (without nyko fans/etc) and is this safe with the rest of my components?
d) Are two 120mm fans enough? quiet enough? Planning on using these:

Here are the drawings (compliments of my bro):

ok that's it for now, thanks to you all in advance..

cheers

Is this a dumb question? Has this been accomplished before? I've strolled through the forums, however, to no avail.. any or would be helpful.. I want to build this, this weekend. cheers

Hi,

Did you have any luck with this? I'm looking at cooling a TV stand and need some options! I guess a standard silent PC fan will do the job, how would you power this? My PS3 will not go in the stand as after about 30 mins of play, its internal fan goes crazy, so it is now on the floor next to the stand, my HD box also gets rather warm.

Any advice greatfully received.
