First time water cooling Will this loop work??

I have read the water cooling sticky but I am still unsure If this loop will work. I drew a picture below. I will also add the parts list. I am using 2 asus TOP 680's and a i7 3770k. also do I need barb fittings to or can I only use compression.




K-Supremacy Elite - Intel 115x (CPU Block)

EK-FC680 GTX DCII - Acetal+Nickel (Gpu block) (x2)

EK-RES X3 250 ( Res)

Swiftech MCP655 ( Pump)

EK-CoolStream RAD XTX (480) (480mm RAD)

EK-CoolStream RAD XTX (360) ( 360mm RAD)

TUBE PrimoChill PrimoFlex™ Advanced LRT™ 12,7 / 9,5mm - Bloodshed Red (PFLEXA-12-R) ( Tubing)

EK-CSQ Fitting 10/13mm G1/4 - Black ( Compression fittings)

Another question I want to use a red colour coolant but people say to use distilled water and a kill coil but with the water blocks for the 680's they have nickle so I don't know hat to do.

Compression fittings are the "preferred" method but a definately harder to use and more expensive. Typically you would use one or the other.

If you're using red tubing you won't be able to tell what color the water is anyways.

If you have the budget I'd suggest using quick disconnects where you can. It makes it 1000x easier if you ever have to remove something from the system.

Some good advice is to place paper towels on top of your video cards for the first couple of days/weeks just to make sure you don't have a slow leak. Water coloring does make it easier to see if you do have one.

Thanks man I have 2 questions. 1 what is a quick disconnect and what does it do. 2 does this loop work?? I know the tubes dissapear in some places but they are getting routed through the back The setup is this. Res>pump>rad>cpu>gpu>gpu>rad>res

I would split this into to loops one for the CPU and a second loop for the video cards you could even have both loops use the same reservoir so in a way it will utilize both rads to cool the whole system.
if you have questions please ask?

Here's an example of a quick disconnect:

http://www.frozencpu.com/products/17129/ex-tub-1461/Pho...

Basically it allows you to remove devices from the loop without having to completely drain all of the water out.

Also if you're looking to have "red" coolant you might want to look at something like:

http://www.frozencpu.com/products/17989/ex-liq-341/Prim...

It non-conductive which means if it leaks a little it shouldn't damage components. However it can stain the components - I have a "blue" 7970 but it's still better than a dead 7970.

Toolmaker does give a good option of using a dual loop. I think the better option in your situation would be to go
pump->res->cpu->res->gpu->gpu -- this allow the radiator to absorb some of the heat before going to the video cards. However this will probably only decrease the temps to the video cards by a little.

Are you sure you have enough room for a 480 inside your system??? I can fit a 360 in mine but I choose to mount the 480 to the back of the computer because I'm using 8 fans in push/pull.

<btw - I have no connection to FrozenCPU - I just use them for most of my watercooling needs due their prices and 1 day shipping due to being so close to me>

Alright but this is also my very first time water cooling so I have no idea how to split the loops

Splitting the loops really means running 2 loops (2 pumps) - 1 complete loop for the cpu and 1 complete loop for the gpus.

oo ok but would I need 2 reservoirs I am using a tube res not a drive bay one

yes - you'd need 2 of them as well in that case.

I really don't think you'll need 2 loops - you should be fine with your plan. Re-arranging the order will only save you 2-3C normally. As long as you have enough of a flow rate and radiator surface area (which you do) you should be fine.

Alright so I will stick with the single loop for now and eventually move on. Thank you !!
