Computer Room Hot?
Anonymous Coward writes "Here is a cool PC ventilation product I ran across. Like many faithful on here, I have multiple computers in a small room which really heat up the place. My office is a good eight degrees warmer than the rest of the house This product called R.A.C.H.A.L (Reduce Annoying Computer Heat And Loudness) vents computer exhaust into the wall, not the room. Might cut down on the electricity bills during those hot months.." Another approach: An anonymous reader writes "If your 'puter is getting to loud, you might want to consider some silent cooling. And the gang at OverclockersClub has just that. A three page review of the Zalman VGA Heatpipe Cooler. This thing is pretty nice looking, and with no power, no noise, what else could a guy ask for? Check out the review here. How come more companies don't do the "silent" thing?" Borked link fixed.
So take off all your clothes!
Chicks love nekkid geeks in hot computer rooms.
How come more companies don't do the "silent" thing?
The problem is, silence is golden. So therefore, in this poor economy, companies can't pay for the gold required and consumers can't really afford it.
Just do the right thing to begin with. If you want silence and no heat use a Cyrix C3. I'm sure you'll say it's too slow for you. Hey, you know what the saying is:
Silent/Cold/Low-Power. Fast.

The cavity at any given point in your wall, if it's to code, is about two cubic feet, surrounded by wood and plaster. Unless you had a magically powerful fan in your PC you won't be getting any circulation at all, because you're pressurizing a fixed cavity. Furthermore, the tube isn't insulated. This is a really silly idea. However, if you vented it *outside*, then you're talking something useful.

then there's the 3rd option. the waste energy manifests itself as mana and enables me to cast lightning bolts to smite the puny dwaves AAAA HAHAHAHAHAHAHAHAHAHA
dammit. I really need to lay off the RPGs.

Hook the tube up to a water faucet, and connect it to your computer's intake fan (rather than exhaust), you can lower the temperature of your computer with an efficient, cooling mist!

As a carpenter/electrician/plumber in my spare time, I think sending computer exhaust to a residential wall is one of the dumbest ideas I've heard of. Venting to another room, crawl space, basement, outside, etc. is OK, but a proper wall cavity with normal studs only has a few square feet of volume. For an outside wall, breaking through a vapor barrier and sending the exhaust to fiberglass insulation is very, very bad.
The only valid application I can think of is for some commercial office space, where usually cheap extruded steel studs hold up sheetrock and the wall tops are open to the space above a drop ceiling. Also, the steel studs have holes in them to allow for cables and some horizontal air movement.
The website does not have any of this information concerning checking the validity of walls. Ugh.
I have 6 pc's running daily with half running 24 hours a day. My whole bill is $60-$70/month for everything (fridge, lights, 32" TV, DVD, etc.). This includes an Athlon and a P4. No SMP at the moment though. :-(
What are you running there to generate that much of an electric bill?
Since the ventilation system restricts airflow somewhat, we noticed some systems had increased chassis temperatures due to poor design.
In other words, your computer will run hotter. While they blame it on "poor design", anything that restricts air flow out of the box (and trying to blow the air thru 4 ' of pipe, then into a wall, will restrict your power supply's air flow) will shorten your box's life. It will also void any warranty (counts as abuse).
This idea is "so" lame that I can't help but think we've all been trolled.
If the excess heat is all from your monitors, then invest in a KVM switch, so you only have one Keyboard, Video (Monitor) and Mouse. While KVM's were once very expensive and seldom seen out side of computer rooms or NOC's, the prices have dropped. Also you can take the money saved on multiple monitors and invest in that nice flat screen you've been drooling over, but could not cost justify! Currently I have one very good 19" monitor, rather then 4 cheaper ones and much more "room" in the room!
So instead of "Here is a cool PC ventilation product I ran across", he should really be saying "Here is a cool PC ventilation product that my company makes."
Sure, it's kinda neat. But I hope

this is woefully unimpressive, and uninspired.
...if i ever find a fridge and hook this up, i'll be sure to post pictures :)
first off, with 16" on center stud walls, constructed of 2x4s, and an average studheight of 92 and 5/8ths inches, you can see that the volume inside a stud wall "cell" is pretty piss poor - roughly 5800 cubic inches.
There are a few issues that make this "solution" stupid.
1) the heat doesn't go anywhere. there should be a correspondingly large diameter cut out in the top plate of the wall, so that the air can escape in the attic (where it might do some good, as the attic is cold and properly ventilated, unlike the interior of a wall)
2) there may be cold water supply pipes in wall. do you want to heat your cold water ? especially if they're copper pipes with a very effective heat transfer characteristic
2a) there may be runs of NM-B (romex) electrical cable in that wall cell. The ampacity of electrical wire is a function of its rated capacity, and while most ampacity ratings are given up to 70C, if this thing were _seriously_ efficient at cooling a computer, then it would perhaps begin to cause problems with in-wall structures
3) how does the national fire code feel about stuffing heat into closed interior walls (made of flame-retardant drywall, typically)
4) if the excess heat it dispells isn't enough to cause any code violations, then it clearly isn't sucking enough heat to be worth installing
5) this does little to eliminate the overall heat+noise of _systems_
My idea for this was to find an abandoned refrigerator, or better yet, freezer, and just putting whole systems inside there, and then running flue-spec double-walled exhaust vent pipe elsewhere. Having all the PCs stuck inside a fridge/freezer (shut off, of course) that was properly vented should make things cool _AND_ quiet. Don't beleive me ? Try putting your battery powered alarm clock in your freezer, and see if you can still hear it once the door shuts. You want whole-system noise cancellation ? Then you need real insulation. Want to keep your office cool? then you'll need to do a lot more than putting a turbluent undersized vacuum hose on the back of your PC.
