Already have a Swiftech Apogee XL CPU block and I don't want to buy any other block for the CPU...

More about : loop config cool

well you cant cool anything with just 1 waterblock... you have to buy a couple radiators, a pump, reservoir, tubing, fittings, fans, fan controller, and gpu waterblocks.

Cost ~$500-$800

i know that i need many more things, but i want to include that Swiftech CPU block as i already have it...

Oh ok. I would say you would need 2 thick 360 rads at least to cool those 290X's and the CPU (without running loud fans).

Don't think ur case will fit that though. How many rads(and what size) can ur case fit?

3 pcs of 280mm and 1 pcs of 360 mm according to the factory data

This is what I found based on the nzxt 630 case u have in ur list :
Front 1 x 140 or 2 x 120mm
Top 2 x140 or 3 x 120mm
Bottom 2 x 140/120mm
Rear 1 x 140/120mm
HDD Pivot 1 x 140/120mm

I have never used this case, but based on pictures, I can see you can fit a 360mm top, a 240mm bottom, and a 140 mm back (might be tight).

That should be enough rad space for your setup. But keep in mind it wont really be a silent build, as you would still need fans to run at around ~1000rpm to cool those beast 290x's

I think the only way to effectively watercool those cards is with a corsair 900D case, and several 360mm rads.

Any other case which have enough space for me? For example the Phantom 820?

Those graphics cards should only put out a total of about 600w which can be effectively cooled using 1 thick 360mm radiator with some fans that are better than an SP120. If you also toss in another 240mm radiator which you definitely have room for. You could get some 780ti's or just wait for the gtx 980's to come out which will be faster cheaper and only need about 340w though. A lot of people tend to go way overboard on radiators for some reason.

I had 1 thick 240mm radiator cooling 2 gtx 580's and an i7 4770k and it did quite well, my fans never got close to max speed unless I was doing a stress test and that's from over 580 watts. And I live in Florida, USA so it's freaking hot most of the year.

Oh if you want a case that's going to have a lot of options for watercooling check out the Thermaltake t81 urban or Core v71. Those 2 have absolutely ridiculous amounts of space without having to tear apart your case.

If possible, I would stick with NZXT Phantom series case as I really like their aesthetics...

Well then stick with the case you mentioned earlier it has space for a 360mm radiator up top and a 240mm in the front.

Your case is doable, however, as in the picture I posted, it will be a tight fit.

I only mentioned getting another case, if you are interested in a super silent build. And I don't think you would get more rad space with the 820.

See if you can fit a EK 360 XTX rad on top (including the fans). Its a very effective radiator.

According to factory data and counting w/ 25 mm fans, it will fit (tight, but it fits...)

Great. If you can fit an EK 240 XTX on the bottom too, and get some good fans, it should do the trick!

I have a loop idea:
First, from the reservoir, the first pump pumps the water into the CPU block, then it goes through the RAM blocks, and cools the VRM. Then i
t cools down in the top radiator, and after it cools the two video cards. Then, a second pump sends the coolant into the bottom rad, where it cools down, and then the coolant go back into the reservior.

... OK so you're new to this, I understand that but what you just said hurt my soul a little, here's why. So 1 pump is almost certainly enough to circulate the water just fine. Adding more pumps in series really won't do you any good and will more or less just hurt you. Each pump draws more power from your PSU and creates more heat that will be dumped right into the loop as well as make a lot of noise. So no, 1 pump is plenty as long as it's a good one.

Now as for your order of circulation, doesn't matter. The only thing that matters is that your reservoir is above and directly before your pump, and that's it. Your water is all the same temperature regardless of where it's coming from. If you were to test the water temperature at any point it's going to be the same at every place give or take 1 degree maybe. What you should do is route the tubing in the shortest runs possible, this allows your pump to be more efficient as each bend and length of tubing is going to add on to the overall pressure drop.

There's actually a really good stickied thread in the OC forums that explains everything about watercooling parts and theory. I would check it out before you go any further.

I agree. No need for 2 pumps or fancy tubework. Just go :

rad1->cpu->gpu1->gpu2>rad2->reservoir->pump ==>rad1


That's usually the neatess looking and most efficient way to do it.

Yea looks Good. Some things though:
-No need for ram cooling. It just makes your loop messy (tubes everywhere in your case). Also ram doesn't get that hot anymore.
-The Fusion reservoirs have been known to leak and be generally low quality. I would read up on them before ordering it.
-Use a fan controller instead of a fan power splitter. Especially since the corsair fans are NOT PWM.
-You will need to buy a killcoil and/or some fungicide additive to add to your loop so algae doesn't grow in the water.
-You will benefit by getting some 45 and 90degree fittings, so you don't need to bend the tubes in awkward angles and give you a cleaner look (not necessary buy recommended).

For the pump any of the D5 variants will work well.

I have heard that killcoil and fungicide additives makes EK nickel radiators corrode.

The EK radiators are copper. I don't see why those would cause corrosion. They are strictly for getting rid of organic materials. And you are using only copper in your loop so that's okay there as well.

Makes water conductive... Kind of defeats the purpose of using deionized water right? I'd just go with a bottle or 2 of coolant with additives in it to keep the biologics from getting in.

Good choice. Coolant is mostly for show. Water is better.

Also Davil, even pure water will become conductive in a loop, as it will pick up minerals from the waterblocks, just like it does with the killcoil.

Good rule of thumb for safe watercooling, liquids are always conductive, don't ever let it touch your components.
