Watercooling i7 and 4870x2

[jaded25]

Well I've been thinking about watercooling the i7 and 4870x2 for a while now and just have a couple of questions about some things. One thing thats been bugging me are the high temps many people are getting with the i7 even with watercooling and the 4870x2 also puts out a bunch of heat. Now would it be possible to run both the cpu and gpu in the same loop or would it be better to run each in two separate loops??

I have a dual 120 rad for my I7 and i'm thinking about getting a 2nd dual 120 for my 4770's.

You could run them on one loop but i think it would be better with two.

 

[jaded25]

How are the temps on the i7??

Yeah I've been looking into running dual loops for each for a while now but wasn't sure if it would be overkill or not.

Right now I've been thinking of setting up a triple radiator for the i7 and a dual radiator for the 4870x2.

I don't think you need a triple radiator for the i7. Dual Loops is not overkill, but I have my i7 @ 3.9GHz and my GTX 260 SC on a PA 120.3 and my temps are fine (34 idle/50-60 load for both of them)

What is your budget?

What you can be looking at is:
Radiators: TFC Xchangers, Thermalright PA's, and XSPC RX's for top of the line
Swiftech MCR's for budget.
120.3's are great if you can fit them, but with the heat of a 4870x2, I would be that on the triple and the i7 on the dual
Pump(s): Swiftech MCP355 with XSPC top (either RESTOP (reservoir pump top combo) or just the top)
i7 block: Koolance CPU 350
4870x2 block: Swiftech Caldera 4870X2
Tubing: Masterkleer or Tygon 7/16" ID
Barb/fittings: DangerDen Fatboy or EK High Flow 1/2" G1/4 fittings (note: the TC PA radiators take G3/8 barbs)

This will be very similar to my system. I'm going to be running (after a case switch) to 2x GTX260SC on a TC PA120.3 and my i7 on a TFC XChanger 240.

My budget is pretty big so I'm thinking of getting mostly high end things.

Right now I'm looking at getting these:
CPU Block: Swiftech Apogee GTZ w/ 1366 plate
GPU Block: EK-FC4870 X2 CF High Performance Water Block or Swiftech Caldera 4870X2 Hybrid Cooling System Water-block
Pumps: Swiftech MCP 655 & MCP 350 w/ EK-DDC X-TOP Rev 2 Acetal
Radiators: XSPC RX260 Radiator and XSPC RX360 Radiator
Reservoirs: 2x EK-Multioption RES 150 Rev.2
Tubing: Primoflex Blue UV Tubing 1/2" ID
Fittings: EF High Flow 1/2" fittings

All this I'm hoping would fit inside a Cosmos S case if not then I'll probably make some mods.

 

[PCTC2]

The MCP355 with XSPC top is probably the best combination you could get. Better than the 350 w/ EK top and better than the 655 in most instances.

Good radiators. Reservoirs are okay, but watch out for the cyclone effect. It can affect your bleeding a little bit and can get annoying. Danger Den Fatboys are a little better, I think, than the EK High Flows, even though I use the EK's personally. Watch out for EK blocks. They don't use standoffs and will warp your board if you're not careful. The Caldera is a good option. The HK 3.0 block and Koolance CPU 350 are better options for blocks if you're going dual loop, but only by a few degree C's. You're probably going to need to do some modding in the Cosmos.

2 loops: go with the same pump/same other parts except for blocks with the loops, it'll be much easier and neater to setup.

if you're going to put the cpu in its own loop check out the EK Supreme, Koolance 350. they're restrictive blocks that offer great performance when in their own loop. otherwise go with the Heatkiller3.0 or GTZ if you're going to put the GPU's in the same loop.

Radiators: Perfect, which are you going to use with which loop? i suggest the triple for the CPU, and the dual for the GPUs.

pumps: why get different pumps? get the same one, it'll match better inside of your case. i suggest the MCP355 (not 350) W/ top. the 655 is too big and bulky.

Fittings: the BP and DD Fatboy fittings have a 12mm opening as opposed to other barbs' 10mm opening, this will help with flow throughout your loop.

all else looks good

 

[PCTC2]

I would suggest otherwise, the 240 on the CPU and the 360 on the GPU. The GPU's put out much more heat than even an OC'd i7. The 240 can easily dissipate 250-400W of heat, depending on airflow. The 360 can dissipate 400-500. The two 4870's will put out 300W+ easily, while the i7 will probably put out around 200W, OC'd.

I would skip the radiators all together and just use T-lines.

Wouldn't you mean reservoirs? Reservoirs make bleeding easier and lengthen times between refills.

 

[jaded25]

Ok took everyone's advice and switched out some parts and here is what it looks like so far

CPU Block: Swiftech Apogee GTZ w/ 1366 plate
GPU Block: Koolance VID-NX295 waterblock
Pumps: 2x MCP355 w/ XSPC DDC Clear Top
Radiators: XSPC RX260 Radiator and XSPC RX360 Radiator
Reservoirs: 2x EK-Multioption RES 150 Rev.2
Tubing: Primoflex Blue UV Tubing 1/2" ID
Fittings: DD Fatboy 1/2" fittings

Would T-Lines really be a better route than going with resorvoirs? I guess I could deal with the time it takes to bleed the system but if its easier then it might be worth it.

It is good to have BOTH. I have both T-lines and Reservoirs in all of my systems because the reservoirs are good to bleed and the t-lines are good to drain.

Ah ok thanks for clearing that bit up PCTC2 well anyways I ended up going through and ordering all the parts and included some T-Lines. Almost all of the stuff should be here soon and I can't wait to set it up and take some pics.

@jaded25. This is an off-topic question, but I noticed in your sig that you are replacing your Asus P6T Deluxe with an Asus Rampage II Extreme. Why are your replacing the MB?

I found out one of my friends needed a new motherboard so I sold him mine and am going to replace it with the Rampage, which I got at a pretty good price.

Quick question for everyone. I got the watercooling parts yesterday and set everything up this morning and was wondering how long does it usually take to bleed out the air bubbles? The loop on the video card is already clear of air bubbles and running fine but the loop on the cpu has had giant air bubbles going in and out and it doesn't seem like there clearing out.
