Additional pump and flow order

post #1 of 7
Thread Starter 
Hi!

I really need expert opinion about water cooling.
Because my spoken english is not so good, i'll show in images smile.gif

- my current configuration with single loop for cpu and mb



- planned configuration with water cooling for gpu's


So I have a few questions for liquid cooling or overclock experts:
1) Additional pump need?
2) Additional radiator or two?
3) Water flow order? Single loop?
4) And I would be very grateful for your advice about connectors/fittings! How connect gpu's waterblocks at Maximus Formula VI?
Now it looking like this:

a single D5 can push it all; so, you're ok there thumb.gif

loop order is less important, as long as you have Reservoir before pump

as for rads.... in theory, you can get away with a single 120 per item, thus one 360 for everything.. IF you dont mind going push-pull and running at full tilt most of the time. rolleyes.gif However, if you like better temps at less noise, you should aim at 240 per item and there you'll probably run in available space limitations.
You should be able to get 240 + 120 in that XB, but it might be tight.... maybe, just maybe you can also get away with a 200mm in the top

I'ld suggest to build some pedestal to house extra rad(s), maybe to house a phobya Nova 1080 or a MO-RA

or, get a second XB, just to house Rads& pump and put them side-by-side or stack them smile.gif

Thanks for your reply!

As a result if I add 2 GPU waterblocks + 120mm and 160mm radiators it will be ok?
I doubt most about 1xD5 pump can handle it, also I do not really want to get additional pump)

Like others said loop order, just do cleanest/shortest route, and reservoir before pump.

A D5 on max setting through a watercooled motherboard, 2 full cover gpu blocks, raystorm cpu block, fittings, 3 rads, you will end up with about 0.6 to 0.7 gpm flow. If you add a second D5 you will have about 1 gpm flow. So a second pump will lower cpu temps by ~1C. So only reason to get a second pump would be for about 1C lower cpu temps or redundancy.

here is martins testing of the raystorm... flow vs core temperature:
http://martinsliquidlab.org/2011/09/26/i7-2600k-cpu-xspc-raystorm/7/

If you use a mcp 35x pump instead of a D5 you will get about 0.15 to 0.2 gpm higher flow which is about 0.3 to 0.5C better temps at that low end of curve.

martin also has a pump and rad optimizer for guestimating flow, version 6.
only place I could find it, click this google search link, and its first link is download.

Thank you!
What about sli water cooling bridge? Given the distance between GPU at this MB http://www.asus.com/Motherboards/MAXIMUS_VI_FORMULA/
Which XSPC sli bridge will fit well? Or maybe i should get something like this by EKWB http://www.ekwb.com/shop/blocks/vga-blocks/multiple-block-connectivity/fc-connection-parts/ek-fc-bridge-dual-parallel-csq-plexi.html ?

If ya didn't buy yet, I don't think I'd try and watercool the EVGA SC series ..... since it has a stock VRM and PCB, it's overclocking capabilities are somewhat compromised. MSI Lightning and EVGA Classified offer the most OC Flexibility but Asus DCII, Gigabyte Windforce and MSI N Series / Twin Frozr all use custom PCBs and beefier VRMs.

Here's the heat load for ya system:

Load Calcs

4770k overclocked - 145
MoBo Chipset - 30
MoBo VRMs - 30
GTX 780 overclocked - 289
GTX 780overclocked - 289
Pump18

Watts=801

I would look to provide a minimum of 60% of that load thru the radiator surface ... remember that ya rad sides, all components, tuning, fittings, res etc all will radiate heat and while 10C is a nice target ... you can be pretty happy at 15C too.

60% of 800 is 480 watts ....

Coolant Temperature Minus Ambient Air temperatureSystem qualification
Less than 5°CExtreme system
Comprised between 5°C and 10°CExtreme to High-end system
Comprised between 10°C and 20°CHigh-end to Mid-range system
Comprised between 20°C and 30°CMid-range to Entry-level system

With a delta T goal of 10C

Each 80mm of 60mm thick Rad will get ya about 34 watts in push/ pull at 1250 rpm
Each 120mm of 60mm thick Rad will get ya about 76 watts in push/ pull at 1250 rpm
Each 140mm of 60mm thick Rad will get ya about 103 watts in push/ pull at 1250 rpm

Each 80mm of 60mm thick Rad will get ya about 48 watts in push/ pull at 1250 rpm
Each 120mm of 60mm thick Rad will get ya about 108 watts in push/ pull at 1800 rpm
Each 140mm of 60mm thick Rad will get ya about 148 watts in push/ pull at 1800 rpm

If I have read ya drawing right, ya have (3) 120s and (2) 80s

At 1250 rpm, that gives ya 3 x 76 + 2 x 34 or 296 watts of cooling (37% of load at 10C)
At 1800 rpm, that gives ya 3 x 108 + 2 x 48 or 420 watts of cooling (52.5% of load @ 10C)

I have many of your same components.

Same MoBo / CPU w/ EK Supremacy / (Naked Ivy Upgrade planned)
Twin Asus DCII 780s w/ EK full cover WBs
Mushkin DDR3-2400

I'm using Alphacool UT60-420 and XT45-280 which gives me 508 watts (62%) at 1250 rpm and 719 watts (88%) at 1800 rpm. I have room for another 240 ... but holding off as yet. It's single loop, the GPUs are in parallel, independently piped (no bridge) and using a 35x2 to push.

If ya uise a bridge or crystal link, you'll want the 3 slot variety..... M6F MoBo uses slot nos. 1 & 2 for 1st card (slot 2 is actually "missing") and 4 & 5 for 2nd ..... 4 - 1 = 5 - 2 = 3 slots
