I once worked at a place where a power supply for a video camera on a
microscope was designed inefficienctly enough that it needed air pumped in
like this: Sticking fans on it degraded the images severely due to vibrations
coupled to all the optics and their housing.
I eventually found the time to design my own switching power supply and get
rid of the air pump. This was for a $600,000 piece of capital equipment for
the semiconductor industry, and I was amazed that no one has previously called
us on such a poor design. ("You guys can't even design a 35W power supply
properly, why should we believe that your optics or image processing or motion
control actually works?")

Yeah. I was in the position of managing various multi-million dollar
supercomputers, and made very rude remarks about the quality of their
real-time clocks. They were anything from 5 to 50 times worse than
my 10 dollar wristwatch.

Quick, patent the idea of opening a window to cool off a computer.

I agree about condensation... this idea seems quite impractical as
better solutions exist. Though thinking about obscure ways to cool
chips does remind me of this paper... which I actually thought was
interesting.

There's a 1992 patent on bringing cold outside air into a walk-in
cooler: http://www.freepatentsonline.com/5144816.html
It has links to related 1970's and 80's patents. Personally,
I doubt that this has ever actually been a new and patentable
idea.
Here's a couple of FreeAire links:

I open the window so room temperature drops.
The room temperature was 24.5 degrees at which point my pc starts making a
little bit more noise.
I open door for a few minutes and room temperature drops back to 23.5 to 23
degrees or so and then pc a bit more quiet...
This is what gave me the idea: why not guide cold air from outside to
peecee...
Then I don't have to sit in the cold wind going through my appartment ;)
Because I set both sides of appertment open to get quick air displacements
;)
Somebody mentions condensation which might be a fair problem... but then
again...
Maybe condensation would be at the hose... maybe it can be catched before it
enters pc ;)
Bye,

Yes, condensation would be a big problem *UNLESS* it is catered for.
Sykfuck's tube should be routed through a condensor stage which collects
the water into a container with a small faucet. The computer user when
thirsty no longer has to walk to the kitchen get some water, he only has
to turn the faucet on his condensation tank.
Consumer resistence to this system could easily be overcome by judicious
use of blinking blue LEDs and a built in ringtone dispenser.

Good point.
Condensation would need to be catched... before the cool air can proceed
further :)

RFI-EMI-GUY
Once I had to perform a radio system coverage drive test which employed
4 laptop computers, GPS, A/D converters and receivers in a station
wagon. It became apparent in the first 1/2 hour that one of the
computers could not take the Florida heat. So off to Ace hardware I went
to get some flexible dryer vent pipe and duct tape. I used one of the
A/C vents to force air into the keyboard of the faulty laptop and got my
3 days worth of drive data.

Drift. The major form of error with quartz clocks. 1 ppm versus 5 to
50 ppm. Actually, one particular supercomputer was over 100 ppm.

heat up a room, and then have to buy more electricity to cool the room.
In winter it's not a total waste but in summer you wind up paying
twice to run the computers. Seems someone ought to invent something
like a house vacuum system so hoses could be connected to the wall and
heat generating devices. Cable boxes, TV's, monitors, refrigerators
etc. Plug in the AC cords, and the cooling hoses.
Cost effective, maybe.
Convenient? No
Feasible? Maybe

Do you really think that you can keep pulling air out, without
sucking hot outdoor air into the house? The negative pressure will pull
air in form anywhere it can, including a crawl space, and areas that
have been sprayed with pesticides. The outdoor air is humid, and could
lead to black mold problems, which can make you sick, or even kill you.
What about the electricity to run the fans? If you want the heat
outside, use the computer outside. An A/C is more efficient than the
fan(s).

Certainly not, but the air outside is usually cooler than the air in a room
with three computers (let's say 1kW). Actually pulling in air from outside
can solve heat problems. This is all under the condition that there's no
aircon in the building.

Don't spray pesticides near your house if you don't want it inside, too. At
least not when your house has a "crawl space", i.e. is one of those cheap
(but overpriced) US buildings, which have no proper isolation, and are very
far from being airtight.
> The outdoor air is humid, and could

Black mold is mostly a problem when the dew point of the air *inside* is
above the wall temperature - i.e. in winter, with unaired rooms (high
humidity) and unisolated walls (cold). With the computers heating up air
inside (but not adding more humidity to it, like sweating humans would),
it's a non-issue. You can have summer black mold in tropical countries
where the bottom 2m in summer usually are so damp that it's fog everywhere.
Solution: Build house on stilts (then you don't have to crawl in your crawl
space), make sure you use tropical wood which resists the mushrooms.
Actually, controlled air-flow similar in spirit to this idea in server rooms
solves quite some problems, and reduce energy consumption (and is actually
state of the art). You cool down outside air with an aircon (say from 30°
to 20°, and reduce humidity), feed it through the fresh air channels
(that's also where the crew works), heat it up inside the servers to 50°C,
and then take it out through the backside channels. That way the aircon
removes only 1/3 of the thermal waste of the servers, whereas a closed
circuit airflow would require to cool the 50°C down to 20°C, and the normal
way things operate (with unordered racks and no air flow control), you even
need strong airflow at lower temperatures to achieve an intake temperature
of 20°C, since the thermal output dilutes the air in the whole server room.
In most circumstances, you can use ground water for the cooling, since most
non-tropical regions have average temperatures below 20°C, so all you need
are some water pumps. In winter, you can heat up entire office buildings
with your servers.
Scaling down that idea to three random computers in a room (e.g. one tower
under the desk, a laptop on the desk, and a HTPC in a rack full of other
equipment, which also dissipates heat) is far from trivial ;-).

Why so complex. Someone should simply invent a computer that generates
cold rather than heat. You'd just have to switch from one system to the
other between summer and winter. After all, if computers are general
enough to replace stereos and TVs, why not go a bit further and replace
heaters and ACs as well? Imagine the benefits: you could grep through
your collection of past cold air...

How big must the hose be to get sufficent air flow?
What would the rating of the fan(s) have to be to move the air thru
those hoses at a sufficent air flow?
Note the longer the hoses, the greater the resistance is to a given
air flow.
How do you maximize laminar airflow for minimum resistance?

The problem is, you would have extreme variations of input air
temperature, which would lead to condensation. It might not be bad,
but ANY condensation in a PC is really bad. -Dave

Well, any condensation would be on the OUTSIDE of the computer case, and not
much of a problem. Outdoor air, at, say 2 C and 100% relative humidity,
when warmed by system components to, say, 30 C will have a VERY low relative
humidity, perhaps only 20%. In fact, static electricity may be a problem,
but certainly not condensation anywhere inside the system case.
You may be thinking of CPU cooling to below ambient temperature by Peltier
arrays or phase change refrigeration. With these systems exposed components
can have a temperature below the dew point of the air inside the system
case. This can cause condensation. But such conditions are exactly
OPPOSITE the conditions that obtain when introducing air colder than any
component inside the system case.
So, a good idea, but should be combined with a way to ADD moisture, when
necessary to maintain a proper operating environment, to the air drawn from
outdoors.
