My New Project (Long Term)

[KarmaKiller]

Well depending on the graphics card you choose, your looking at either a triple 120 rad, or maybe could get by with a dual with high cfm fans. You could even do 2 small loops, but that's 2x the parts and 2x the cost/space/time to setup.
But that's up to you.

I myself would look into these though:
Petra's Tech Shop
Petra's Tech Shop
(if you get a 260/280)
Petra's Tech Shop
Petra's Tech Shop
or you can get the DDC pump with res top. That is the best performer according to martinsliquidlabs.com But that also gets pricey too.

Now depending on the rad you get, that really determines what fans you get. Some rads work just as well with med/low speed fans. Others need the high cfm fans. So that is kind of up to you.

Now more questions to answer while I sleep. lol
1. Do you only want one loop in your tower? Do you want one big loop, or 2 small loops?
2. IF you do one large loop, you'll need a large rad. Do you plan on mounting this internally or externally? If you do 2x smaller loops, same question.
3. A lot of this really depends on that hardware you picking out. Some of the GPU's/Cpu's run cooler then others. So if you get 2 cooler running parts, you may not need 2 loops, or large rads, so on..
So really think about the parts your gonna get first, and that will help make a lot of the decisions for you.

I'm signing off for the night, so I'll check back in the am.

Assuming Rad is short for Radiator....

I plan to do SLI with 2 GTX280/260s. Though I'll mount it outside the case (the case itself will be a Thermaltake case so it'll have fans as well. Though I'll be taking some out to do the Water Cooling.

Case Choice: (I'm sticking with this one!)
Newegg.com - COOLER MASTER cosmos S RC-1100-KKN1-GP Black Aluminum ATX Full Tower Computer Case - Computer Cases
Getting the clear side panel
Newegg.com - COOLER MASTER RA-1100-KWN1-GP Transparent Acrylic Side Window Panel - Case Accessories
(Sure if I get the see through I won't have the 20cm fan...BUT I think the mix of the water cooling and 3 top 12cm fans and the 12cm fans in front and back should be adequate)

So to answer your questions:
1. 2 Small Loops
2. Externally
3. 2 GTX280/260's and Q6600.

Ok..
So some more questions.
1. Do you want full coverage block on your GPU's, or are you ok with a uni-sink and then just a block?
There are also these blocks.
2. Is noise a issue? Do you mind hearing your fans? Do you plan on having a fan controller hooked up to these fans?

[SirRob]

1. Full Coverage, since I plan to really overclock this system.
2. Noise isn't a issue, I play with noise canceling headphones. So doesn't matter how loud the fans are or the pump is. And Yes I plan to have a controller set up to control the fans.

[KarmaKiller]

awesome..
Well then you can pick up those EK blocks, here:
EK Waterblocks - EK-FC280 GTX SLI - Acetal
that's a good price too.
The pumps, since your getting 2, I would not go with the res tops. That'll be expensive. I instead would go with a couple Db-1's.
dB-1 Compact 12v Pump

The block I'd use for my Quad:
Petra's Tech Shop
with
D-tek Fuzion V2 Quad Core Insert

One thing I haven't mentioned is shrouds. It's best to use these. It cuts down on the noise a little, and helps performance of the rad. With these, there are no "dead spots: in air flow. If you use fans right next to each other, you'll notice in the middle where the fans meet there is little to no airflow. By pulling your hand back off the fans a little, you'll notice the air flow returns. That's basically the idea behind shrouds.

For my loop, I have a single Black Ice 240mm rad that does the job just fine with my quad and NB. You might be able to make it by with just a single 120 rad, but I personally have no experience with those, so I'll leave that open for someone else. Dual rad's perform very well though.

You could pick up a couple of these for res's. Or just add in a T-line and a plug for it, either way it's about the same thing.

Fans, personally I got some Yate's of Jab-tech for cheap. They are noticeable in noise, but they move a good amount of air.
If you want more movement then that, then you can get some panflows.

Tubing I'll leave up to you.
Might pick up a bottle of PT-nuke also.

Think that covers it really..

[SirRob]

By couple of Db-1's, you mean 2 or more? Please explain how this works though. By having the 2 GTX SLI Waterblock, and the D-tek Fuzion V2 Quad Core Insert and the Db-1's, how does this all come together to work. With the reservoir of water with the CuSO4·5H2O (btw I'm a chem major so I know this stuff) and the tubing, does the tubing run through each of these with the water mix and takes the heat out and brings it back to the reservoir or what?

[oldfolks123]

here i made a build for about 2000

Newegg.com - Once You Know, You Newegg

and this CPU
Newegg.com - Intel Core2 Quad Q9400 2.66GHz 6MB L2 Cache LGA 775 95W Quad-Core Processor - Processors - Desktops

Haha i just remembered what u said in the main post..a keyboard monitor etc ill just leave it on here though lol

[KarmaKiller]

1. Don't get any pre-manufactured water cooling. Very bad idea.
2. Don't ever, ever pay that much for a GX2. That is a horrible price.
3. Just disregard that post all together. That is not the way to go IMO.

Ok, well you said you wanted 2 loops. Which means you'll have one loop just for your CPU, then one loop for your Graphics cards. So basically your building 2 water cooling systems.
So for the CPU loop, you'll need 1CPU block, 1pump, 1 Res, 1 Rad, fans and tubing. Then for your graphics cards loop, you'll need 2 GPU blocks, 1 pump, 1 Res, 1 Rad, fans and tubing.

So on the GPU loop, it would look something like this:
GPU block #1 >> GPU block #2 >> Res >> Pump >> Rad

Then on the CPU loop, it would be:
CPU block>> Res>> Pump >> Rad

Basically, you want the Rad right before the hottest running part. That way you get the coolest water into the hottest part. Make sense?
Also, another general rule is you normally want to have your pump pushing into the Rad first. I've heard people say because of pressure, but IDK personally. In my experience, I got the best temps going:
Block > Res > Pump > Rad

And the easiest way I can explain it. Is basically your Res holds all the extra liquid. The pump moves the liquid through the blocks. While they are in the blocks, the liquid picks up the heat from the fins within the block, and transfers that to the Rad. Which has air blowing through it so it cools it down.
Does that make sense?
Is that what your were even asking?
( I get confused easy) lol

[SirRob]

yup, that's what I was basically asking. Now I just need to know why my other comp shuts down after POST XD

[KarmaKiller]

Heat is the most common cause. Have you dusted it out lately? Make sure all the fans are running.
