bro i know what yer doing...ive been reading you posts...first...if you get the right stuff..just putting it on the flat edge and putting the peice together will suffice...i would recommend some silicone after the "Epoxy Platic Weld" just in case you miss a spot...to be honest im still trying to concieve your vacum concept...Periodically suck out the hot air?..or always on?...why not just throw some copper piping in their and have a fan blowing on it.?
How big are most of these chiller compressors everyone is using?
edit
so if i got that tiny little 70$ kenmore a/c unit basically in a nutshell i would have to
1. gut it
2. make or buy a res and place the evaporator in it
3. get some denatured alcohol and some antifreeze for corrosion
4. good tygon tubing
5. then bend the tubes and whatever and now i'm a little confused, you take a pierceing valve and drain the charge until you find the lowest temp, but then how do i patch that piercing up?
insulate and stuff and then finished.
so is that the essentials, probably in the wrong order, but is that the basics?
28 pages is a little too much info for me to go through right now. What I dont understand is how that cold reaches the cpu. Is he using water.... or what? If he is, how is the water cooled. Can someone explain this whole thing to me? If what he's doing is a bit more advanced for a first timer, what do you guys recommend thats still effective? Keep in mind, I have never done anything like this, I have never worked on A/C units nor have I ever done any professional electrical/HVAC work or welding. I dont even own a blow torch nor know how to use one. Are there different methods for using an A/C unit?
I'm a n00b as well, but take the time to read. One thread I keep hearing over and over is that if you don't do this right it can be quite dangerous. And if you're not going to take the time now to just read up, then I doubt you're going to take the time to be careful if you do anything like this. Like all things, if it's worth doing, take the time to do it right {jumps off soapbox}Quote:

Now that that's over...I have a question as well. I think this summer I'll be doing an AC into a chiller. I'll have lots of help, my bro is an EC tech at Boeing and he's got friends that work the HVAC systems so I'll have lots of help.
System that will be cooled will be running a socket 939 AMD and dual 6800 Ultra video cards. Which of these AC units would be the better start?

?
Well the thing is Im incredibly busy right now. Is there a guide or something I can look at?
Wow what a trip that was , I had some problems on the way of building my chiller and most of it was bfg rma service. I had a problem with my computer it shut down with that wierd blue screen protecting the windows and never new why!!!! But when I got into building my chiller I seen on my video card It was missing a chip on the board and right then I knew that was why my computer was acting up... So I rma my card and getting tech to believe it had a missing chip was hard because they dont believe anything so anyways I got a card and it was missing the same chip that my first card was missing..So I call them back and to make this a short story it took 3 months of back and forth to get a good card what a nightmare !!!!!!
So here is my next problem I found a 12000 btu ac and it was free thanks mom but I cant get it to fire up .... I think it is the thermostat it had a long little tube connected to it and it cracked off in the build... can someone help me on getting this thing running thanks...
Hi, I've just read through all 28 pages, most useful information, however, i still have a couple of questions before i commence on my own system over the summer.
I currently have an Eheim 1250 pump, what kind of temperatures will this be suited down to? I'm hoping for final temps of around -40 degrees celcius. I also have a DangerDen TDX CPU block, this has a lucite top, are there any problems with using this kind of top? I've also got lots of Tagan R3603 tubing, would this be usable down to -40?
Thanks in advance!
Yah, i also have the same question, on the plexi top and what kinda temps can most pumps handle? Like my Mag3, do plexi tops crack under such subtemps?Quote:

Can something be done with a Mini Fridge in the same manner AC units were used in this thread. I got a spare Mini Fridge, the compressor I peaked at and says 1PH, 80 watts.
Or are AC units cheap enough for it to be Worth it.
A mini fridge is not capable of holding a constant heatload. You risk burning out the compressor, as well as getting high temps (the condensor is no where near rated for a PCs constant heat output).
Just try to pick up an AC unit. $80 at walmart come spring (may or so, before summer hits)
The smallest you can find is still overkill, so a 5000 btu unit will do a great job.
I would suggest brass topped versions for those kind of temps. Also if you submerge a mag3 in your res it will most likely crack being that cold. My advice would be to get a little giant pump and run it in inline. Tygon R3603 should be fine, just insulate everything a lot. PM me if you have any other questions.Quote:

Dam well it looks like I am going to be taking it into a shop to get it fixed up after I get it all mounted up. I completely removed the 110 fan. I am using 120mm 12v computer case fans. I bought a 120v to 12v 3 amp transformer, a crossover and a 4700mf capacitor from radio shack. I cut the wiring harness off of the 110v fan and have it running to the transformer. I have room on the condenser for a total of six of the 120mm case fans. Right now I only have three but will be getting the rest soon enough. I could not find the small cooler that you guys are using so my reservoir is a bit bigger….. Probably too big, 34 quart, LOL. I think I may be putting a spacer in it to take up some room. I’ll post some pics when I get closer to getting it finished.
Hmmm I was at the auto part store today and found a 12v fan for a radiator I think it is about the right size but they want $54 but it has a fan shroud.... I am reconsidering my case fans and maybe will buy this fan..... My transformer has a middle line so I can run 6v and my AC unit has a regular and turbo speed (both are currently wired to my transformer so they do the same speed) I think I can figure out a solenoid circuit to do 6v and 12v (turbo)
Great thread people!
I have caught the subzero addiction and am in the process of building a liquid chiller.
Any thoughts or advice on a ehiem 1250 (http://www.dangerdenstore.com/produc...&cat=26&page=1) and a RBX cpu block (http://www.frozencpu.com/ex-blc-230.html?id=HC5ieSy6) for down to -40c?
1250 is a good chiller pump. RBX sucks. You want a simple block. MCW6002 works perfect.
Hmmm i read somewhere that these are a lot easyer to insulate too.
Being all copper brazed together,i'd feel a lot better using this block with extremely cold temps. Not to mention it's performance.

Well that is why propane is a good refregerant. !!!!Quote:
