im looking to build completely on my own a refrigerated system. does anybody have anything i might want to know before hand? im willing to have this be as ghetto as neccisary. looks are not important the first time around.

Get EPA certification, it's a 75 dollar test at most refrigeration supply. Ohh yah, you might want to read several hundred page manuals on the subject. Go to training classes to learn how to blaze fittings. See if you ghetto it, you stand a good chance at sufficating yourself to death if something goes wrong and you dump refrigerants into the air at a moderate level and many will act as a nerve gas, or eat your lungs out.


Iateronmly - EPA Certification level "Universal"

so there is no safe way about it then? or are you merely just trying to squander my dream? im enrolled in an electronics project class in my school where they will provide the funding for whatever i need. so when i say ghetto i mean i dont want to use something like the vapocool or prometeia. i just wanted a more diy approach.

are you Danimal from zr2.com?

if so welcome to a cool site.

First off, i don't know much about the refrigeration side, but if you want a really stable, and effective solution to PC cooling try out the Asetek kit for $280.00
There was just a huge write up of this kit from a member here and it has got me convinced to buy it.

i am not that danimal, but i can assure you that i can live up to any good reputation that he has.

i am trying to stray away from any set packaged kits. i really wanted to do it myself. im wanting to refrigerate the air inside the case and seal it off. i dont want to use water. and if possible, no fans. call me crazy eh?

Wait wait.. you just wanna refrigerate the air? Not direct refrigerant cooling to the processor?


Also irregardless - refrigeration system to do both will take fans, and compared to the compressors the noise is neglible.

Well I am glad you asked there bud...Besides the possibility of killing yourself and others,
The license you must keep current, to purchase, possess, transport, transfer, handle and store referigerant, requires a test that proves your ability to perform these tasks, with physical and financial resposibility.
You must prove you know how and must become bonded and insured..
.Untill that time I wouldn't use Ghetto and Refridgeration too closely together..
.doing any of the above activities, unliscensed is a class B Feolny...
What seems tame enough to keep a glass of milk nice and cool for ya....Haz a potential of destruction like you would'nt belive...I would try to apprentice with someone who had plenty of accident free years in the field, and then realize the dammage it would/could do if you ever do scew something up....and if all this insite doesn't steer ya clear of this Haz Mat, then please go out in the middle of nowhere where you can only hurt yourself, I also heard "Leggos" are the hot ticket!!....:No No"

you dont think its possible to use an existing refrigerator to safely and legally cool the air inside the case?

A regular refrigerator's set up won't keep up with the heat generated by a modern computer. Maybe an old Intel 120 system. Refrigerators are designed to drop and maintain temps on items with a set amount of heat, not a constantly generating source. They aren't designed for heavy duty cycles (time running to time idle)You may want to look at smallish style AC units you'd put in your window during the summer.

cool deal. i will definately keep that in mind. im up for any crazy ideas, so thank you. i plan on posting all the pics step by step through the process, but god knows when that will be.

It may not be safe, but I'm pretty sure it would be legal.

hmm i could be wrong but putting your computer inside of some refrigerator could be very harmful like BA said. Correct me if im wrong but having circuits in an area where there is a high amount of condensation could prove to be an expensive mod . If you were to do this i would think about some kind of industrial type dehumidifier. Like i said i could be wrong though so wait on one of these pimps to let you know if it would be cool---hehe did i really mean to say that?

Doomsday Cooling with Dual-Cascade -Check out that link just to give you a taste of what can be done, and what is involved in a high end "Crazy off the Wall" mod if you have the time, money, proper skills and certification

This kind of fabrication is not something a beginer or intermediate skilled person should attempt. It takes years of hard work and learning to reach this level safely.

We are not here to crush dreams, but if I was a rookie race car driver, do ya think I should go out and build a Pro-Stock or Winston Cup car my first season?
Ya could, but it spells disaster...

Look at the Direct Die watercooled system Zennzzo made a while back (In the Archives under extreme cooling) and look through the rest of custom cooling threads, see what inspires you..

Build a watercooled system with hand selected parts, there are many here who can help guide you through it. Don't grab a kit, just see how much work is involved in design, testing, trial and error and maintainace. This will give you basic skills to build from.

Then let us know when you want the keys to a Top Fuel Dragster

Holy crap that doomsday thing is crazy!!! 3049 mhz with the A64, wowza!!!!! This guy is crazy, props to him

Well...

refrigerating a case = condensation = death to your PC...

Cascade cooling = insane... those people have tonnes of experience with phase changing most notably owning and mastering phase change first. You strike me as someone who is begining to venture into this realm for the first time...

if you want great temps go and buy a Prommy or Vapo-Chill they run $500 to $1000...

the vapo chill and prometeia just arent what i want to do. this is my plan so far. ive aquired a pentium 1 machine. its minimal, and it was free. this will be what i do the tests on for quite a while. what i want to do, is cool the air inside of the case using a refrigerator, and seal the case off to keep the cool in. if humidity is an issue, then i plan on buying a used dehumidifier from the thrifty adds. like ive said before, i dont want to use a water circulation setup. i want to cool all the air inside the case.

If you don't believe the advice about the risks then go to a local refrigeration shop. I'm sure they'll agree with us.

first off, it doesn't sound like he wants to tinker with the internals, just put his components inside an existing refridgerator...

Danamial, the problem with that is, is that a pentium 100 will not produce the kind of heat more modern chips will, just because it cools the pent. 100 well, doesn't mean you'll get the same results with an AMD XP line, or a P4... it produces a lot more heat, and puts more strain on the refridgeration unit.

If you are going to have any chance for success, everything, and I mean EVERYTHING will need to be insulated to prevent moisture from shorting it out. The CPU and other all other elecrical connections will need a generous coat of non conductive grease. There is a spray on clear sealer called "Konform" that may help for everything else, but I lost the link for it.

What you are trying to do is similar to submerging it in water, because condensation will be hard to avoid even if you add a dehumidifier (Wich heats the air I believe, very counter productive)

I would leave the Power Supply, CD Rom, Floppy and Hard drive outside the "Air Box" the less you components you have inside, the less heat,and not as many things you will have to insulate.

Actually, a dehumidifier cool the air. It draws it over a cooled set of coils, causing it to condense and run off the coils and into a tank or into a drain... which is why ours ices up when you try to run it at temps below 50* F.
