Looking for experienced help on my loop.

Hello,

Currently working on picking the parts for my first ever water cooling loop, the parts that I would be using for the build are ;

Asus R4E
i7 3930k
GTX 680 HC (when available) in Tri-SLI
AX1200i

At the moment, I'm looking at my loop being (All parts are from FrozenCPU);

Black Ice GT Stealth 120 X-Flow Radiator - Black // COUGAR CF-V12HPB radiator fan

XSPC EX560 Quad 140mm Low Profile Split Fin Radiator // Noiseblocker NB-BlackSilentPro PK-3 radiator fan

Swiftech MCRES Micro Rev. 2 // Res

Swiftech MCP655 Variable Speed 12v Water Pump w/ G1/4 Thread Ports

Bitspower Ultimate G 1/4 Thread 3/8" ID x 5/8" OD Compression Fitting

Swiftech Apogee HD

-----

I was wondering if this is enough cooling power for a soft overclock (4GHz on the 3930k, small OC on the 680 classy). I'll be running everything in a single loop and still have enough space for a XSPC EX280 if I require more cooling.

Do I require more cooling?!

Also, if anybody could give me any advice if I should change my pump/res to a 5.25" res or any other suggestions. Money is of no real concern considering those Bitspower fittings are 10$ ea -.-

I would get a bigger res if you can fit it, maybe an ek multipotion reservoir like this:

http://www.frozencpu.com/products/11183/ex-res-230/EK-MultiOption_RES_X2_-_250_Advanced_-_Liquid_Cooling_Reservoir_8_Total_Ports.html?tl=g30c97s165&id=dSJUyM48&mv_pc=27266

Or if you want get one with a pump installed to save on space:
http://www.frozencpu.com/products/14133/ex-res-301/EK_D5_X-Res_Top_140_Pump_Top_Reservoir_Combo_w_D5_Variant_Pump_Installed.html?tl=g30c97s165&id=dSJUyM48&mv_pc=27188

For try sli a single quad rad will prob not be enough. Each 680 without oc is about 200 watts, so 600 on cards alone plus 130 for the CPU without an oc is 630 watts. That rad could probably just about cover it without ocing otherwise you need maybe another 240/280?

Bigger reservoir doesn't really get you anything except that your loop holds more water volume, which isn't really beneficial except in the time leading up to working loop equilibrium. It's mainly a matter of personal preference and the actual reservoir design of choice.

XSPC EX560 Quad 140mm Low Profile Split Fin Radiator

This should work well for you- quad 140mm should be great depending on where you plan to mount it. If you have this, there really isn't a need for the x-flow 120mm...that isn't going to net you much more cooling capacity. Take the total radiator volume in cubic millimeters x the cooling coefficient from the watercooling sticky in the rads section:

143 x 36 x 600 mm (WxDxH) = 3088800mm^3
3088800mm^3 x 0.00023129193 = 714.414513384 watts @ 10C delta

3x195 = 585w (GTX 680's total TDP @ stock) + 130w which is 615, right in line what scopey86 posted above. With this, you have some room for overclocking, but not a lot. If overclocking is definitively on your list, you might consider another small rad...x-flows aren't really my thing, but they should perform about as well as a dual pass.

Thanks guys for the input, as for the 120 X-rad, I'm using a Silverstone TJ11 case which has space for a 120 on the roof. As for the 280, that would go into the basement along with the 560 and PSU. Pretty tight in other words.

As for TDP, I was told that the 680 Classy pushes TDP around 180 @ stock clock, so rounding it off to 200 sounds fair enough.

For the 3930k, I was planning on OCing it to 4GHz @ 1.2-1.4v which puts out around 175-240w.

As for the the res, I'm going for a sleeper look and keeping it very low key, I can't STAND the 'BLINGBLING YO' watercooling builds with the entire thing looking like a giant green/blue/red flashlight. My res would either go somewhere in the basement near the PSU, or be located in the 5.25" area. That or getting an actually 5.25" res.

I'll probably stick the 560 in the basement, gives me more space to work with. Anybody have a recommendation on a res that I should upgrade to if needed?
