Hi guys,

I am looking at building my first water-cooling rig to cool some GPU's ONLY. This will be my first water-cooling loop so I have done a tonne of research and read through the sticky, however I would love somebody to give it a once over to make sure I have all the correct parts and that the loop is adequate to cool my components,

So, without further ado, I am looking to cool 2x Gigabyte Windforce 290 graphics cards. They are around 250w-300w tdp each so I nee to cool around 600w.

My parts list:


  • EK Water Blocks EK-FC R9-290X - Acetal+Nickel x 2
    EK Water Blocks EK-FC Terminal DUAL Serial
    EK Water Blocks EK-D5 Vario X-RES 140 (incl. pump) (http://www.overclockers.co.uk/showproduct.php?prodid=WC-411-EK)
    Hardware Labs Black ICE Radiator GT Xtreme 480
    Scythe Gentle Typhoon 120mm 1850 RPM - 3 Pin x 4
    XSPC G1/4" to 3/8" ID, 5/8" OD Compression Fitting (Black Chrome) x 8
    XSPC HighFlex Hose 3/8" ID, 5/8" OD, 16/10mm, 2m, Black x 3 (total 6m)
I have done some measurements and I can fit the RAD in the roof of my HAF X and use the gentle typhoons to push and the HAF X standard 200mm fans to pull. I will need to mod the case but that is something I am not afraid to do.

The three major questions I have are:
1) Does this pump/res combo have enough power to pump around this loop. I have looked up some psi info and I think my loop is around 3 psi, but I can't work out how powerful the pump is (I think it has a head of 3.7m)
2) I have a rear exhaust fan and a cpu that that blows out the case. In order to make more air go through the radiator would I point these inwards?
3) Is this enough rad? This is a 120.4 setup and I am pretty sure it should be ample based upon this review (http://martinsliquidlab.i4memory.com/HWlabs480GTX-Review.html).

To be honest, the pump/res combo is my real concern, I can't seem to find a lot about the pumps and I don't know if a 140 res is large enough when I have such a large rad. I know it is vital to not let the pump run dry. Another option could be this: http://www.overclockers.co.uk/showproduct.php?prodid=WC-272-XS&groupid=962&catid=2133&subcat=1845

Thanks for your help!
 
1. Yup, a D5 is plenty. Have the GPU blocks arranged in parallel and you will definitely have enough power.
2. Wouldn't bother, though removing the rear fan makes sense to me. Having it intake air will just drag dust into the case.
3. Seems about right, I'm interested to see how you will fit it into the HAF-X though.

The size of the reservoir has no impact on performance unless your talking literal buckets of water, wouldn't be concerned about that. A larger res does make it quicker/easier to fill the loop, but its just a convenience thing. If your careful the pump wont run dry.

Only issue I can see with this setup is if your Gigabyte cards use a non-reference PCB design, then you could run into issues fitting the GPU blocks.

Thank you so much for your reply!

1. Awesome. I may use a bay-res instead as I am not sure of how to mount this thing.
2. Thanks, good call :)
3. I am inspired largely by this post http://www.techpowerup.com/forums/threads/the-rise-of-skynet-my-first-water-cooled-rig-haf-x-480-radiator-sli-580-ftw-hc.152977/. The rad this guy uses is 520mm and the one I am looking at it 517mm. It will fit with the smallest of mods :).

EK Waterblocks have confirmed that the WF3 uses the reference PCB. :D

ooOOOOooooo do I press the purchase button!?

Ooohhhh nice rig.

I was going to use this for the x-fire link EK Water Blocks EK-FC Terminal DUAL Serial
and I think I will get some angled fittings for the rad.

Also, silver coil and yea a drain would be good. What is best placement for that? After pump?
