My pci slot fans are rated to blow almost 3 times the air of those component coolers and they suck air in the side and blow it out the end like them too.
I supose that I could stick one on the back of the stereo though a standard 80mm fan might work as well.
Something along the lines of the cabnet cooler in your link is what I was thinking about with the fans (in the back at least). That kind of give me the idea of perhaps putting some in the side if nesasary though.
In all honesty, I really wonder if much of the stuff needs a lot of cooling. The stereo only gets used for the radio or if the kids want to play with the microphone (music/cd's/movies get played through the htpc and a set of logitech speakers). The dvd player only gets ocational use (disks that are too scratched to want to play on the htpc). Most of my disks (movies or music or whatever) are already riped to the htpc (with the new drive I just got the htpc has 2.4TB and the bedroom computer (networked and sharing storage both ways) has about 800GB.
It's never really been an issue till I got the lcd tv which seems to radiate a crap load of heat. Perhaps I could seal the back of the tv space off, and install 2-3 120mm fans. I was thinking that this would be pretty cool to use
but then again, the 120mm fans would actually push more air together (rated at 39/56/79 CFM at their 3 avalable speeds).
So the question would be, blow air foward over the tv, or draw air in and out the back? The bigest problem are huge gaps around the tv. Air would be drawn past the tv but I'm not sure how well it would blow over it or through its vents. Thats why I was thinking of having a fan (and perhaps a duct) blowing air into the vents and or under the plexi and across the screen. I'm pretty sure I will set up at least a pci slot fan or two blowing under the plexiglas.
Perhaps mounting the fans behind the tv (close to it so they blow on it) might work beter than vent fans all the way at the back of the cabnet (a good foot and a half away from the back of the tv), or maybe both (seal the back of the cabnet, fans blowing in, and a fan or two blowing right on the back of the up closer).
I have a hard drive mount (this one)
that has two remote tempature sensors, so I could probably get some ideas of tempatures (maybe even stick one of the sensors into a vent an inch or so). Fyi I'm not talking about the one installed in the htpc (not sure if you can see that in the picture or not, but I have two, one just sitting on the shelf).
Truth be told, thinking about it, the back light has got to be throwing a crapload of heat at the screen. If I have air blowing across the screen (under the plexiglas), wouldn't that make it run cooler than if it were just sitting in open air like a tv stand? With the tv sitting in front of the cabnet like it is, air blown under the plexiglas would not get blown into the cabnet (unless fans in the back were drawing the air back, so maybe they need to be blowing air in and foward). Blowing air directly on the back of the tv or in the slots might not even be nesasary?
Fyi I found a picture of the entertainment center that shows how it stick out a little better (not the greatest picture as clicking it goes to a dead link but that center section sticks out 5 inches so the front of the tv is 4-5 inches foward of the rest of the entertainment center).
