Vega's 2600k + Quad-6970 chilled build

post #1 of 47
Thread Starter 
Trying to set up a chilled water cooled setup with the following components in a triple loop (1x CPU, 2x 6970, 2x 6970):

i7 2600K
4x AMD 6970 GPU's
ASUS P8P67 WS Revolution
G.SKILL Ripjaws X + Turbulence II Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2200 (PC3 17600) Desktop Memory Model F3-17600CL9D-8GBXLD



Chiller: New LG 15,000 BTU window air conditioner. As large as I could find and still stay 115 V. I went with new for the warranty and if I screw something up in the setup I can claim it was defective and return it to the store. : I went with a window unit as I plan on kicking the computer heat outside in the spring/summer/fall and heating up the house by bringing the unit inside in the winter.

Components:







Haven't bought a pump, whats considered some of the best these days? Thinking about dual Iwaki MD20RLT. I have to pump 1/2" ID tubing with a total length of about 30 feet. To lessen condensation, was thinking about going Tygon Norprene 1/2" ID 3/4" OD high pressure. http://www.tygon.com/norprene-a60fib...re-tubing.aspx


Some questions on the air conditioner: how cool do you think this unit can get the CPU and 4x GPU's? I am thinking about using this to house the evaporator: http://www.rubbermaid.com/Category/P...od_ID=RP091241

It's one of the only ones that I can find that could fit my 25" wide x 5" deep evaporator. Plus if I don't want a super large amount of coolant I could just put water tight containers in there to control the volume. I plan on using distilled water plus water wetter and small blocks of pure silver. I can add propylene glycol to the mix if I somehow get below freezing. I won't use any toxic stuff as I have pets.

Anyone know if this compressor is good at all? I couldn't find anything on Google.

Anyone have any good ideas on bending this evaporator out of the unit? I'd like to extend it out about 5 inches and angle it at 45 deg for the Rubbermaid cooler. I have heard horror stories about kinking the tubing and such, or even worse and venting all of the R-401A. Would a heat gun help at all where I need to straighten/bend?

















Any tips in general for what I am trying to accomplish here?

My thinking has strayed a bit from the chest. With the ice chest I would have to pull the evaporator out, cut a slit for the pipes etc. It would be unwieldy and it would be a huge pain getting the A/C unit in and out of the window with the attached ice chest.

Then I thought, why not make the evaporator ice water container built into the A/C unit itself? There is actually quite a bit of room once the evaporator Styrofoam and fan is removed. Obviously a rigid ice chest would be near impossible to fit in there seeing as the evaporator is just an inch or two shy of the whole unit width.

So then I was thinking, don't they make insulated thermal bags/sacks? I could do a layered insulated bag type setup. Wrap the whole evaporator in the bag and there would be a single exit/entry point for all lines/connections that could easily be sealed air tight. This would allow the whole unit to be self contained nice and tidy plus I wouldn't have to do much if any tube bending.

So the compressor and condenser coil hangs outside dumping all the heat and noise. The only thing inside the house is the evaporator and everything else is sealed. With no evaporator fan and the evaporator chamber sealed from the condenser chamber, you could see how this would be a quite quiet setup. I could insulate the temperature probe so that at lower temperatures it thinks its at a higher temperature so I could control it with the remote.

Now the hard part is finding large, tough, durable, thermal insulated bags.

Where have you seen quadfire being horrific? On the new 69xx series all I've seen is it working pretty good in some benchmarks. lol @ fraud, are you serious?

Benchmarks and real playing are different things.

In my experience, at least with the 580s and the 5870s, benchamrks scale great, but games don't scale above 3 cards. Even with the 69xx series.

Anyhow, good luck.

Here are some numbers for 1x vs 2x vs 3x vs 4x HD6970 (from Lab501)

Poor translation (as usual) but the graphs are nice.

He's got a good point, and what you described doing is considered fraud.

Not, that's not a fraudulent practice at all.

Ya, those are at a low 2560x1600 resolution and quad-fire still shows scaling. I will be running 3x 30" so quadfire should prove fairly useful.

If for the small chance I had to return it, they wouldn't know the difference between a faulty unit and a slightly modified one. You think they care? Back when I was in high-school I used to work retail and people would return questionable stuff all the time. No one could care less as in the grand scheme of things it doesn't matter. I don't think I'll lose any sleep over the hardware store anti-modified air conditioner return law.

It's just like people that buy video cards/CPU's with non-overclock warranties. They overclock them and if they fail, they RMA them as DOA. If you don't think that happens constantly, you are naive.

Amazing build, watching....


You can see by those benchmarks... 2x huge increase, 3x a more, 4x just a little more. Oh well if you can do it, why not right?
