Default Need advice on watercooling alot of hardware

Ok, so since I've been stuck on a 17" Macbook Pro a while I finally decided to get a computer for gaming. This is what I have:

1x Intel i7 920 D0
3x Corsair 2000mhz Dominator-GT
1x Evga e762 x4 SLi Classified
4x Evga GTX 285 Classified

Looking at the 2 case choices (Sorry xaser, you may fit the evga X4 but you are effing hideous) I like Lian Li more than Mountain Mods, so Lian Li it is. I saw some worklogs where they fit a 120.3 rad in teh front. Thinking of stacking 2 rads in the front and trying that.

My goals and priorities are simple:

1. It must be quiet
2. It must look nice
3. It should OC somewhat

I can flex requirement #1 to increase #3 - #2 will be a given with most WC setups anyway.

Here is what I have picked out for now with what little I have researched so far:

1x Primochill Typhoon III Reservoir System - PEC
$63.95 x 1 = $63.95

1x Swiftech MCP655™ 12 VDC Pump
$76.95 x 1 = $76.95

1x Swiftech Apogee XT Extreme Performance CPU waterblock
$75.95 x 1 = $75.95

1x EK EVGA 4-Way Classified full cover motherboard block
$119.00 x 1 = $119.00

4x EK EVGA GTX 285 Classified full cover GPU block
$114.95 x 4 = $459.80

2x Swiftech MCR320-QP-K Triple 120mm Radiator, 1/2" Swiftech Metal High Flow
53.95 x 2 = $107.90

PrimoFlex Pro LRT Black Tubing - 1/2in. ID X 3/4in. OD
$2.00 x 20 = $40.00 (Playing it safe, tubing is cheap anyway)

Bitspower Black Sparkle Compression Fitting - 1/2" to 3/4" - BP-BSCPFD-CC5
$5.00 x 16 = $80.00 (2 Extra)

Primochill PC Ice - Clear
$10.95 x = $21.90

But any and all help is appreciated! I have built alot of computers in the past and sold them off, and they all work fine, but this is the first time I'm venturing into water. The 4 cards and chipset is so loud it drives me nuts, not to mention the heat!

Default Re: Need advice on watercooling alot of hardware

With 4 cards I'd definitely recommend doing two loops - one for the CPU/Chipset and one for the GPUs. If you have enough money I'd also highly suggest cooling the mosfets as well.

I'd get the following components:

CPU - Swiftech Apogee XT or Watercool HK 3.0 - 89.99$ or ?
Chipset&Mosfets - EK EVGA X58 4x SLI Classified Full Board Cooling Block Kit - 149.99$
GTX 285 - 4x Danger Den DD-GTX285 Version 2 VGA Full Card Liquid Cooling Block - 4x 144.95$
2x Black Ice GTX 240 radiators(360 for the cpu if you have enough room) - 2x 90.95$
2x EK DDC X-RES Top 140 - Acetal -Laing DDC / Swiftech MCP350/355 - 2x 64.95$
4x120mm Noctua fans 4x 24.99$
+ Tubing + Fittings + Barbs ~60$

Grand total: 1231.54$ + ~60$

Were I you I'd just get a decent loop for the GPUs as the cpu air coolers are good enough to get you to 4Ghz without any problems(they're also completely silent if you go with a good fan).

I am waiting for the ABS Primochill D3 resevoir (no cracks) before i buy.

Why DD over EK for FC 285 blocks? and I think 120.3 rads over 120.2 rads, the case is huge xD.

Get a used radiator from a car junkyard, a water pump and tubing from a fish store, and one of those large floor standing fans (the ones in plastic enclosures) that people use to cool their homes in the summer. It should build you a mega cooling/resevior.

Car radiators always sound like a good cheap alternative, but they are not. DIY watercooling is not the the best way at all now days.

I always just pour a cup of water down into my computer and the temps always go down almost right away.

Probably the most solid advice you can get.

I'd agree fully with this, and also, DO NOT do any ghetto setups with car radiators like what was just suggested. The high performance radiators for pcs are much better at cooling water than big car ones (designed for radatior fluid).

2 loops is definetly the best idea too. With all the distance that you'll have to push water through it would need either a single loop with multiple pumps... but that way you're worried about heat-buildup after leaving the cpu / gpu area.



Choice 1

2 loops, one being

cpu -> chipset -> mosfets (optional) -> memory (optional... very rarely is memory water-cooled) -> res -> pump -> rad

2nd loop being

gpu 1 -> gpu 2 -> gpu 3 -> gpu 4 -> res -> pump -> rad





Choice 2

Single HUGE loop (would probably require multiple pumps...)

cpu -> chipsets -> mosfets (optional) -> memory (optional) -> radiator -> pump -> gpu(s) -> pump -> radiator -> res

This would let you only have 1 resevoir... I'd suggest multiple radiators between the cpu and gpus though no matter which route you go.... those gpus are going to produce alot more heat than you might expect.

Seriously though, you don't want a large loop or large loops. As the fluid cools each device it will rise in temperature, by the time you've run through those four 285 video cards the fluid will be pretty hot and have it's thermal absorption greatly reduced.
Along the lines of what Toss recommended, I'd suggest breaking the video cards into two loops, which would require three radiators instead of two.
Also for quiet operation I'd recommend nothing smaller than a 120mm fan (the larger the better), for the simple reason that you can run them slower and move more air than a smaller fan (which would require a higher speed).
