I agree with the room heating comment. I use the 4 - 6 PCs running in my room as supplemental heat. I'm in there most of the time (9 x 10 computer room), so as long as I keep the door shut, it stays comfortably warm in there. If I could do this, without the fan noise, it would be a lot nicer though :)

That reminds me of when I first got into web design. It was during the winter months in a large family room in the basement at my parents' house. My computer desk was about the only thing in the room. The computer I had at the time didn't put out much heat, and anyway it was no match for the drafty window right above the desk. I guess I could have warmed up my fingers by putting them on the CPU or something, but it was easier to just blow on them. I just about froze my fingers off that winter.

I rate ambient noise as being important to me when buying a machine, and I usually pay extra for after-market fans to keep the noise down.

I would love manufacturers to start taking this issue more seriously. Choice of fans is important, but also the hard drives as well. Apple fans can look smug here I think - Apple do take this stuff seriously. The PC world? Not so much, and it's a real shame.

90% of my excessive volume and heat generation comes from various rack-mount appliances (like Cisco switches), not pee-cees. It doesn't look like these things are very friendly towards that type of environment.

The basic concept might still be sound, though. Turn your rack into an enclosure, add some intake fans, and vent the entire rack's exhaust somewhere else. (I wonder what the exhaust temperature for an entire rack would reach?)

Re:Living in the Pacific Northwest (0)

Anonymous Coward | about 12 years ago | (#5027502)

It depends on where you are exhausting the heat to. Remember, in most systems, all of the heat is still exhausted to the surrounding air. It may be 70F inside the case, but the system is creating the same amount of heat, just more is being moved to the outside of the case. That said, if you exhausted heat more efficiently from your systems, but still only exhausted to the surrounding air, you would technically be heating your space more.

I don't get it (2, Interesting)

Anonymous Coward | about 12 years ago | (#5027467)

Where does the heat go once it is in the wall? Won't it eventually radiate back out into the surrounding environment? That might be ok if your goal is only to reduce the temperature gradiant between the computer room and the rest of the building but overall I don't see how this is going to reduce the amount of heat inputted into the building.

Unless we are talking about an exterior wall, in which case it SHOULD be well insulated but you never know.

Hmmm... wonder how those roaches and other critters living in the wall are going to enjoy a blast of heat from my power supply fan? KFC (Kentucky Fried Cockroach) anyone?

Re:I don't get it (1)

AuraSeer (409950) | about 12 years ago | (#5027539)

If your system's exhaust air is hot enough to fry anything, you've got a whole other set of problems. Even my hottest-running case blows air that's cool enough to breathe.

All your roaches will get is a nice warm place to lay their eggs. (And a direct path to the innards of your PC, of course.)

the tradeoff (2, Troll)

tps12 (105590) | about 12 years ago | (#5027473)

Like anything else, the quest for silence and coolness involves a tradeoff, or Devil's Deal.

The obvious way to keep your PC quiet is to strap pillows to the case, but this increases heat retention. Likewise, the obvious way to keep your PC cool, adding case fans, makes your PC louder.

It turns out that you can't have it both ways...a PC generates excess energy, and it is going to manifest itself either as heat or as sound. It's basic conservation of energy. So choose your poison now, and learn to live with the side effects.

Re:the tradeoff (0)

Anonymous Coward | about 12 years ago | (#5027532)

not really -- you can get passive heat sinks instead of the miniturbo fans on P3 processors,
you can use heat pipe passive cooler for a high end video card that would otherwise have fans.

then you can replace the fast loud case fan with a higher performance larger, slower fan which will
do the same work but be very very quiet.

you can also replace your drives with much more quiet ones

sometimes, these quiet options are more expensive,but not always.

Re:the tradeoff (1)

Modern Hamlet (311094) | about 12 years ago | (#5027577)

This isn't entirely true. Any addition to the system that disperses the sound or heat further than the immediate vicinity of the computer (i.e. the room) will create a localized net reduction in heat and/or sound, without the expect addition of the other. Yes, SOMEWHERE ELSE will have to compensate due to the those peskty laws of physics. But that's why we have funaces in the basement of most homes. picking nits, tom

Re:the tradeoff (2, Informative)

BrianH (13460) | about 12 years ago | (#5027649)

I disagree completely. While PC's generate a lot of heat, the trick to keeping them alive is moving that heat to another location...not turning the heat into sound. With my own daily driver, a P4 overclocked by more than 600Mhz, the loudest noise I hear is my hard drive head seeking...and even that is barely audible. Why? Planning! Rather than plunking down some cash for a small diameter, extreme RPM, LOUD series of fans like so many overclockers do, I mounted three low noise, high pitch 120MM fans with some very carefully planned (and custom fabricated) internal ductwork. The end result is the same airflow as the smaller, high RPM fans, but at a noise level that won't wake the baby.

Choosing your poison just gets you killed...I'd rather engineer a solution that'll get me what I want at no cost.

Re:the tradeoff (2)

geekoid (135745) | about 12 years ago | (#5027660)

more options:
water cooling,
quiter fans.
You could also bring in cooler air from another area(properly filtered, of course).
you could put the computer itself into a closet, and put the things you need to use to access it on your desk(couldn't use IDE).
Or would could make the HD external, that would reduce you heat as well.

so you see, there are far more Avenus then pillow or fans.

PhantomHarlock (189617) | about 12 years ago | (#5027500)

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.


Re:That's not gonna work. (5, Informative)

tomhudson (43916) | about 12 years ago | (#5027664)

Of course this isn't going to work. And in colder climes, if the air did circulate, you're going to get warm, moist room air being pushed past the vapor barrier and ruining the insulation. At this point, you don't have to worry about excess heat anymore - since your insulation's R value just dropped to zero.

You WILL have to worry about mold and mildew, as well as condensation ruining the wall panels, or running along the framing before pooling somewhere and causing more damage.

...except that often, the pressure inside the wall is greater than in the room, hence the market in little foam inserts so cold air doesn't gush in between the spaces of your electric outlets, switches, etc.

PC fans are incapable of moving air against even the slightest resistance- if you're not careful, you could end up frying stuff when the fan stops moving air. Especially in the summertime, when attics can be VERY hot, you could end up force-feeding your PC 100 degree air when the wind blows a certain way.

Also- what about the second exhaust?

JUSTONEMORELATTE (584508) | about 12 years ago | (#5027512)

Heat (and nosie for that matter) are only a big problem if your top priority is speed.
My latest system has a top priority of silence, with raw horsepower a second thought. The purpose is to record audio in a live setting (burn off CDs of a church service immediately following the service.) so I don't need a 2GHz P4. Once you back away from the bleeding edge, heat becomes much less of a problem.
The solution in my case is a VIA C3 650, decent copper heat sink and no CPU fan. The video needs are minimal, so no GPU fan. The thing draws less power than most, so the temp-controlled fans never turn on.
I'm still trying to decide if the liquid-bearing hard drive is worth the extra $100 though.

Moisture problems? (4, Insightful)

gorillasoft (463718) | about 12 years ago | (#5027525)

It seems to me that venting the heat into your walls could cause condensation or other moisture problems inside of your walls. It also seems like you could get some very strange noises resulting from the forced air going into an enclosed space. The backpressure from exhausting into the wall could also shorten your fan life or possibly worse. If you have fire blocking in your walls, you could be blowing hot air into a space as little as 16" x 24" or so, and once that heats up you'll be getting the heat back into your room as it radiates through the drywall.

You also couldn't effectively use this on an exterior wall because insulation should be taking up all of the available air space inside the wall cavity anyway. Also, not all of the heat your computer generates is going to be exhausted by the fan, so this may not result in a huge reduction anyway, and it becomes even more problematic if you have more than one exhaust fan. Just a few thoughts I had.

Have these people ever seen a wall being put together?

You generally have a 2*4 box sealed on either side with drywall. So, you essentially would just be pressurizing this box, and eventually overwhelming the ability of your machines fans to pump air. Sounds like a great idea!

That would be true, if drywall and lumber construction was anywhere near air tight...

It may not be airtight, but the point is perfectly valid.

A cardboard box isn't airtight either. But stick your computer into one, fold the top shut, and see how long it takes to overheat.

Here is the correct link: R.A.C.H.A.L. [computerexhaust.com] .

Neat picture, though, I don't know whether it will really cool down the room. Won't the heat just build in the wall, and not dissipate as quick because of the lack of air. Then, the walls will be warm and again warm the room. Hmmmmm.

Ummm.... it's Winter right now. My room (at college) would be positively chilly without my two computers running. It does raise the overall temp by 8-10 degrees (f), but that is welcome at this time of year. It also means I don't have to turn the heat on very high.

In summer, I'll go home and the parents have central air on all the time, and cold for summer (my mom doesn't like the heat much). My computers then keep my (slightly larger) room tolerably warm for summer. Like 70-5 instead of around 65.

What I'm saying is: GO HEAT!

Wouldn't R.A.C.H.A.L (Reduce Annoying Computer Heat And Loudness) really be RACHL, such as the United States of America isn't USOA? Aren't Ands, ors, thes, all not supposed to be used in an acronym?

Is it just me, or does any computer really make that much noise?

nice advertorial!! wow, a piece of plastic pipe and i'm supposed to pay for this? What if I don't want air blown into my walls? What if there is stuff in there like insulation, dead rats and umbrellas? What a dumb idea... what you need is like a bathroom fan that actually has an outlet somewhere, otherwise you are just blowing warm moist air into your walls. Hello mold and rot.

Exhause into the wall cavity? Seems restrictive (1)

EddyGeez (31487) | about 12 years ago | (#5027562)

After checking out the site, it seems that all you do is drill a 1.5" hole in your wall, screw on a bracket over the hole so the hose can connect easily, and then connect it to the output of your PS fan.

Somehow, I think reducing the output from 80mm down to a 1.5" tube is going to cause air flow restrictions. But then, on top of that, you direct the exhaust into a wall cavity, which is designed not to allow air to pass thru? What if the wall is full of fiberglass insulation, or even worse, blown-in cellulose or that expanding foam stuff?

I would think that a better solution would be something along the lines of a "clothes dryer vent", with a direct connection to the outside (you know, they have the little louvred doors that "blow" open from the exhaust air). Plus, dryer vent pipe is around 4" if I remember correctly, which would have significantly less airflow restriction than a 1.5" tube.

Flex-hose in a variety of sizes is commonly used in work shops all over the place. See for example:

http://www.oneida-air.com/ductwork/flexhose.htm [oneida-air.com]

I would think using parts available from sites like the above would allow a significantly better "exhaust" system to be home-grown...

If you hook it up to your sink (5, Funny)

Anonymous Custard (587661) | about 12 years ago | (#5027564)

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!

Anonymous Coward | about 12 years ago | (#5027581)

I telecommute full-time and have lots of machines in my home office. I suffer from the same warm room problem, but I find that most of the heat comes not from the CPU's but from all the CRT's.

Give me something to help divert that heat and I'll be happier.

Still, this is a neat approach towards trying to solve the problem. Kudos to them for the effort.

From the FAQ (2)

jhines0042 (184217) | about 12 years ago | (#5027592)

What if I have two exhaust fans?

If you have two exhaust fans, the ideal solution would be to install two ventilation systems. If you only want to install one, install it on the power supply fan, this generates the most heat.

You mean, they don't have an option to hook two hoses up to one hole in the wall? Seems like they just want to prey on their customers and stupid people. But I repeat myself.

It works well.

Unbelievably bad idea (5, Insightful)

msclark (413170) | about 12 years ago | (#5027608)

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.

Karamchand (607798) | about 12 years ago | (#5027626)

..because those vents aren't made for blowing throw a pipe which is some feet long. They just can't. So you'll have to get stronger (and louder!) vents.

Moreover I have to wonder where the air is going to go. Not that walls are completely airtight but they aren't exactly open either..

hmmm (2, Insightful)

lophophore (4087) | about 12 years ago | (#5027632)

Let's take an 80 mm fan (diameter about 3 inches) and pipe it through a 1.5 inch hose into a closed space. Do the geometry and calculate the area. Not too efficient.

Why not just jam the fan to stop the noise and keep the heat in the case?

But that's the way I like it. It's cold here half the year, and my computers provide supplemental heat. Plus, the noise (I call it "Machine Music") is callming and soothing, and I feel like I'm actually working. Well, sometimes.

Just the other day I was helping a friend install RedHat 8 on brand spanking new machine (bought just for Linux BTW :) and he had purchased a top of the line P4 2.4GHZ from DELL Desktop fully loaded. I was absolutely astonished at how quiet it was. He lives in a dead silent neighborhood so you can hear everything. Even the 48X CD-ROM was quiet and this is with a Geforce 4 Ti 4200 in it as well. In fact my Laptop was noiser than the Desktop. I guess my point is that some companies are starting to take noise seriosly and paying a bit more for a brand name does have it's perks.

j_kenpo (571930) | about 12 years ago | (#5027658)

This is the exact same thing as a dryer vent, except it blows into the ever clean area between the walls. Id have to modify this thing with a fan to suck the air out of the case and blow it into the wall, and a small filter to prevent any sort of blow back into the case. Even then, at $19 a pop, i could just excess flex hose from my dryer and modify a 3 switch wall cover, and Id pay about 2 bucks... That or if the temperature in my room was really that big of an issue, id get a fan for the room...

OverclockersClub Graphs (4, Insightful)

stever00t (618001) | about 12 years ago | (#5027666)

Does anyone else find it horribly bad journalism/science to report with a graph where one bar is a third as long as another bar, yet the large value is less than 1% larger than the other because they start the graph at a random number instead of zero, and then just using a graph break in the scale?

If you make a bar graph and the values are 1% different, the sizes of the bars should be 1% different. Why do they not understand this?
