First time full water cooling, is my loop okay ?

post #1 of 19
Thread Starter 
Hello,

So this is my first time going full water cooling, and probably my fourth build. I've been doing this since I was 14 (I'm 19 now), so I'm not a complete beginner, though I'm no expert either.
I've decided to do a single loop that will split between the GPUs and the Motherboard/CPU.
I have done a small sketch, and was looking for some advice/confirmation that I did not forget anything, or do something wrong, before I start buying everything.

First, here are the parts :

Main Components :

Case : Cooler Master HAF X with 4 Red MegaFlows (Already Owned)
Motherboard : Asus Rampage III Formula (Already Owned)
CPU : Intel Core i7 950 (Already Owned) ->Probably going to buy a 990x when the price drops a bit this July/August
GPU : 3xEVGA GTX 580 3GB (once they're out in a couple of weeks)
RAM : Corsair Dominator GT 12GB (3x4GB) @ 2000MHz with AirFlow 2 GTL and AirFlow Pro Dynamic Memory Temperature and Display
Sound Card : Asus Xonar Xense with Steinheiser Headset
PSU : Corsair AX1200 (Already Owned)
Main Drive : OCZ Vertex 3 120GB
Storage : 4xHITACHI Ultrastar 7K3000 2TB in RAID 10
Optical Drives : 2xAsus BW-12B1LT
Fan controller : Scythe Kaze Master Pro 6-channel

Waterblocks :

CPU : Koolance CPU-370
Motherboard : Koolance MB-ASR3F
GPU : 3xEVGA Hydro Copper 2 + Backplate (with Koolance Dual-Vid connectors)
Pump : 2xKoolance PMP-450S (with 2xKoolance CTR-SPD24 24V Pump Controller)
Reservoir : RP-452X2 (with 4 blue LEDs)
Splitter : 2x Koolance's SPL-XUFY5B
Draining : Koolance's VLV-13TSPL
Flow Meter : Koolance's INS-FM17N with ADT-FM03 (frequency adapter)
Radiators : 4xHardware Labs Black Ice GTX 480
Radbox : Customed made by Danger Den, based off their External 3x360 Radiator and Pump Case
Fans : 32xScythe Gentle Typhoon AP-15 1850RPM in push/pull
Fan Grill : 16xMod Smart 120MM Black WIRE-FORMED Fan Grill
Coolant : Koolance's High-Performance Colorless coolant (LIQ-702CL-B)
Tubing : 1/2" ID 5/8" OD Blue UV reactive
TIM : Innovation Cooling IC24 Thermal Compound

Other :

Speakers : Corsair Gaming Audio Series SP2500
Monitor : Dell Ultrasharp U3011
Keyboard : Logitech G510
Mouse : Saitek Cyborg R.A.T. 7
Lighting : Logisys CLK12UV2 Dual UV Cold Cathode Kit 12IN 3.0MM (and a blue one) with 2 military toggle switches.

And finally here is the sketch I made :
Attachment 205917

The un-resized image can be found here :

If you know better alternatives, I'd love to now them !
Also, you might think this is overkill...
Thing is, I'm aiming for a 5°C delta, and according to Martin with a 1550RPM fan, this radiator can dissipate 300 watts of heat. I'm assuming a worst-case (impossible to happen) situation where my PSU would dump directly 1200watts of heat on my components. So I'll use 4x480mm radiators. I know that the realistic heat dump will probably be around 800w, but I'm also looking ahead in the future.
If 2 years from now, I decide to do a build with 4 GPUs, and 2 CPUs, my heat dump will be bigger, and I might need them all.

I know this is a very long post, but I have one last question : is it really that important to flush my radiators and blocks before using them for the first time ? From what I've read, it's a really long a boring process...

Thanks a lot for the help !

Just to let you know, you will never need 4 480 rads for any kind of setup whatsoever. With that you could run completely passive without any fans and still not get anywhere near danger temps. Now I know you're going for extreme cooling so if that's really what you want then it's up to you.

From what I see, everything looks just fine, have fun and post tons of pics so we can enjoy!

EDIT: Just saw the coolant. 95% of this forum is going to tell you to use distilled water + silver kill coil or PT Nuke because coolants eventually break down and clog up your blocks. If you're ok with cleaning them every few months and constantly buying more coolant, then you're good to go. Otherwise go with UV tubing and distilled water.

Flush the rads FOR SURE, with water + vinegar before using. Many times they have flux left over from the machining process and you DO NOT want that in your loop.

I'll answer your last question first. It is definately a good idea to flush. Too much important hardware at stake not to flush. Now, as far as the loop. I would suggest you will be better off with two loops. One for CPU and mobo and another for gpus.

Yeah, I know. But also, that way my fans will be able to run really quiet.

As you've probably seen, I have components in my build that aren't out yet, but hopefully will soon be ! As soon as I get everything together, I'll start posting pictures, but that will probably be only in mid-July/early-August. I'm presently on a trip with my family, and won't be back home for a couple of months.

It's colorless coolant. And I don't mind having to buy bottles from time to time. As you've probably guessed, money is not really a big concern to me !

Okay, thanks ! I'll probably use this guy's method, it seems to work very well :
Thanks for the quick reply !

Firstly, welcome to OCN!

Seems like you have done some research, and have a fair bit of cash to spare...

Sounds good, I would like to echo what Kinru said about the coolant, but for slightly different reasons. The clear Koolance stuff wont really break down, it is pretty much just water anyway, but it won't perform any better than distilled water. Seriously, plain distilled and PT Nuke or KillCoil is the way to go, cheaper and just as effective.

4 * 480GTX rads is more than twice what you will need, but hey, if you want it go for it.

And yes, flushing the rads is a must. Simple choice, do it now or flush the whole loop later.

Parts look ok EK blocks are comparable to the koolance ones if you wanna look at them as an alternative.

I would really avoid the coolant even if it is colorless you would be fine with distilled water and pt nuke/kill coil. All coolants are a wasted expense imo nothing has proven to be better all around than distilled water.

Yes clean your rads the last thing you want is flux in the gpu/cpu blocks and having to re-clean your system after a week or so of it running. Vinigar is no always necessary my xspc rx 360 rad i just cleaned with hot water and when I took my rig down 3 months later for inspection and the addition of my 5970 wb my cpu block was clean. But you need to check to see if the manufacture uses water soluble flux or not. If they dont you need to use the vinegar mix I wanna say its 5% iirc.

There is no benefit to having 2 loops, it has been proven and stated MANY times here. It is way better to have 2 pumps in serial and have a single loop that goes through everything.

It makes things less complicated and saves money as well as there is no decrease in performance.

Sorry I did not see that the coolant was colorless, however, like others have said, nothing does better than distilled water so I would still highly recommend that.

The other thing I would suggest if you are going for silence, would be to get either the SR-1 serires or XSPC RX series rads. They are optimized for very low speed fans and with 4 480s you could run at 1000rpm which is completely silent and get the temps you are looking for.

Oh, I just thought about another thing...the flow rate. Do you think it'll be above 1GPM ? Because from what I've read, the GTX480 is almost as restrictive as a CPU block. So it means I'll have the equivalent of 9 blocks in my system (4 rads + 1 cpu + 3 gpus + 1 mobo). Will the two PMP-450S at 24v be able to handle that ? Or should I add something like this pump ?
post #9 of 19
That pump is WAAAAAAAAAY overpriced and unnecessary.

2 MCP35x's in serial would serve you way better. Or you can get the double top for the MCP355 which would be nearly the same (no PWM and maybe slightly louder which can be handled with getting a foam pad for it).

I also have the equivalent of 2 loops, because my main one splits into 2. That means that the gpus and mobo/cpu receive water that'll be at about the same temperature.
