Hi,

I am looking to watercool my i7 920 CPU and 2 x 5970 video cards. I know absolutely nothing about watercooling but i am trying to get my head around it all

I know i will need a new case, the 800D seems very spacious so i might go for that one

This is the list i have put together so far, please tell me if anything is incorrect or anything you think i should change. Thanks for your patience!

Black Ice SR-1 480 Radiator
EK FC 5970 Plexi Full Cover VGA Water Block x2
Swiftech Laing D5 Vario MCP655 12V DC Pump
EK Supreme i7 High FlowClear Top
XSPC Acrylic Dual 5.25" Reservoir for Laing D5
Aquacomputer Gigabyte VRM Waterblock (Do i need 2?)


I know i need fixtures, connectors and tubing, but i have absolutely no idea what sizes of each to purchase. Does it depend on the sizes of the block?

Any help you could give me would be appreciated

many thanks
 
The 480 rad won't fir in the 800D without some modding. The best setup for this case without mods is the SR-1 360 and a Stealth GT 120.1 rad. So you effectively have a quad radiator. This setup means you have the Triple in the top and the single on the rear.

Good choice of pump, provide very good flow and relatively quiet. The D5 bay res is a good choice aswell as it keeps your pump and res in the same place so less loop arrangment is needed.

To cool the Gigabyte board you can't just buy VRM coolers as the heatsinks on the motherboard are linked so you would need a full cover block. I don't know what exact board you are using yet as you didn't say.

Barb size is all relative to the tubing you select so for the blocks it doesn't matter. These barbs are very good, nice and easy to install and are high flow. They are 1/2" so 1/2" tubing fits on naturally however some people put 7/16" tubing over them for a tighter fit. Either way it doesn't make a massive difference. I recommend this tubing. Best to buy more tubing than you need just incase you cut bits too short. So 2 or 3 metres is usually suffice.

For fluid/coolant any of the EcoXP series we sell is great as they don't stain and they are not conductive so you don't have to worry if you spill some on your expensive hardware.

Any more qeustions feel free to ask :)
 
S'ok :)

You will need a UD5 full cover block, we can get them instock for you (provided your buying from us)

The setup will cool everything you have listed but becasue of the limitations of the case, not being able to fit more than a quads rad's worth of cooling, the temps will not be the greatest. The GPU's will run cooler than air but the CPU will run around on par with a H70 (if Overclocked).

To be honest there is no easy way to cool an i7 and 2 high end GPU's without modifying a case. The only other case I can suggest is the Lian LI-PC-P80B or Silverstone TJ07 which stiull require modding to fit the required rads.

It all depends what you want from the setup, if it is quietness then you will be fine. If it is sub artic temps and maximum overclocking you won't be able to achieve it.

In summary you will have better temps than air with less noise (and better looks).
 
Well if I didn’t purchase an additional 5970 I am assuming that would bring the overall temperature of the water down?

I was hoping to achieve a 4.2Ghz (HT on) overclock on water, as I can’t enable HT using air. It’s pushing the temperatures up to around 82 degrees
 
Ive got 2 loops of 120.3 in a 800d and a 5970 that runs at abt 52 C. Sure it could take another one if I could afford it

In which case, it's too early to be even thinking about what parts you're going to get. You should be researching researching researching. If you need some links to some guides, here:

Hi i have a corsair 700d case, i am planning to cool only my core i7 930. These are the parts i have chosen.

I plan to overclock as high as i can go with ht on, what could i achieve? 4.5 maybe and if so what temps would i be looking at? Also will these fans be quiet enough? If not could you reccomend some better ones. Thankyou.

The only parts which confuse me are the tubing sizes and fittings, do i need anything else? Is everything correct? Thanks!
 
Ok thanks for your advice, i cant find thicker white tubing!! I want the thicker tubing because i personally think it will look better in a case of my size, i will read those posts that you previously linked. A few questions though. Should i save my money and used distilled water, or spend almost £40 on this fluid xp stuff, is it worth it? Should i use the compression fittings or high flow fittings with a clamp? I much prefer the look of the compression fittings, are they safe? Thanks very much.
 
Also about the compression fittings, it says that they are designed for "Thread to 3/8" ID - 1/2" OD hose fitting that will fit all tubing which has a 3/8" ID and 1/2" OD (1/8" Walls)". ID must mean internal diameter, but what does OD mean ? overall diameter? Im not sure. If the tubing is 3/8" and the compression fitting is for 3/8 why wouldnt this work, this is the only part which is confusing me, I have read two of the guides that you posted, they were great, if you could just answer these questions, i would much appreaciate it.

OD is outer diameter, and with compression fittings the tube is held in place by tightening the outer screw piece of metal over the tubing, therefore the inner and outer diameter needs to be correct for these to fit.
 
You can get 1/2id 3/4 od white tubing search for
XSPC 1/2" ID - 3/4" OD (13-19mm) High Flex Tubing : White
or
Masterkleer 1/2" ID - 3/4" OD (13-19mm) Flexible Tubing : White

Bear in mind if you use compressions this big you may need some rotaries as i found out as i could not fit the compressions on my res, gpu block or cpu block (i changed from a heatkiller 3.0 to a supreme full nickel) without using rotaries.
 
Would these parts be fine together? If not could you please link the correct anti kink and same coloured tubing. I couldn't find any different sized compression fittings, do they only do them in 1/2, i want to order only from oc uk for postage etc.

Also is this cpu block good for a single cpu loop ?

The other one suggested is out of stock and £5 more, i think that they are the same, just that one is see through? is that correct. Thanks! I want to buy tommorow, so replies today would be great. I will be post pics during the build, hopefully i can get a decent camera!
