Cold air blower, air conditioning unit

post #1 of 11
Thread Starter 
I've just picked up a cold air blower air conditioning unit from work that gets too cold for comfort if you stick your hands infront of the air outflow. Could i take this very cold air and stream it through the bottom front of my pc as i have no fan there? It was chucked out and thought it might be worth a try but didn't know if its wise to use such cold air directly over my components.
Any advice would be appreciated thanks

Sounds similar to my window AC experiment (I couldn't get the discarded AC to run though, it would trip a breaker as soon as I tried to power it up) I ended up trashing the unit because my mom didn't want a huge peice of junk in my room.

I guess what you want to do is "cold case" Bascially, you can just take off the side of you case and set the A/C in front of it so that it blows onto the board.

If you are really good at it, you can also make an adaptor to connect to the outlet. Duct the cold air into your case.

You should be able to keep the inside of you case close to freezing (around 32F to the low 40's F)

Could there be any moisture build up on the components from channeling the air directly through my case, i don't fancy becoming the proud owner of regret but at those temperature's you've suggested i'm very tempted to try il push this 1.8 venice as far as it'l go. Which brings me on to my second issue, does anyone find that they are or becoming addicted to Tweaking?
I can't seem to turn on my pc without the delete button being pressed followed by various changes to the bios.
AIs there a patch for this particular problem ?

RUNEX2K many people have done similar things in the past with good results.

Condensation should not be an issue since the air that is blowing over the computer components will be dry. Where you might get into trouble is when you turn the AC off and expose your parts to the room temperature air, it's possible that the components could be below the dew point of the ambient air. Testing this is easy though, have the AC blow on say a coke can and let it cool down. Once it's reached it's lowest temp, turn off hte ac and watch to see if any water vapor condenses on the can. If some does, you might run into moisture issues, if not then you should be ok.

I've become really excited with the thought of chilly temperatures, even after some successfull voltage drops in the bios thats not taking my cpu over 42c no matter what i try loading it with (this a64 3000 venice is awesome). Anyway's thanks for the adive and the tip with the drinks can, i shall be trying that sometime this week after ive purchased some nice ugly looking tubing. Im thinking of using three pipes, one large going in to the bottom front of case and two smaller fluorescent tubes going from the bottom front run to the top front then top rear with lots of little drilled holes directing the air over the drives cpu>psu and finally sucked out through the dual otes fans . Should show up nice with the two brite blue 12v leds im putting in

thanks again and nice pc rig you got yourself. my pc reaks budget lol

A dehumidifier would take care of the possibility of condensation upon shutoff.

An AC is basically a dehumidifier + chiller. So let the dehimidifier run w/o chiller until temps = room temps = no condensation.

Someone build a mini-unit that fits into a 5 1/2 in drive and lowers temps 10C or more and you got a product.

you could put it up against the side w/ the panel on and if you got hole put fans in them to suck it cold air from the A/C

already done it, tested on a old junker, never had a problem, parted it out and all the parts still are working. The air conditioner takes all the moisture out of the room, no condesation i've ever seen.

This is my current "work in progress" staying cool until i go to water. Going to get new case and more than likely make custom water blocks - gotta love working for a auto manufacturer.


If you can't duct it, f*ck it!

i have something similar to this, i was going to modify an ac unit to cool my computer but during the winter i don't have to. i currently have my computer sucking in air from outside which is around 23 F, -5C. and my processor temp is at +5C, i am running a overclock from 3.0 to 3.888 and am writing this post so it is stable enough to use. without this cold air i would run temps around 60C
i am using an antec 1200 so i dont have to worry about any snow getting in because of the dust filters, the other night it was a little colder and i read a temp of -3C. with watercooling do you think that is good?
i have not had problems with condensation but that is mostly because of the dry cold air i am using. if it were summer i would be more worried about it.
