I was looking at ekwb.com because they make the water blocks that I need for my Gigabyte xtreme gaming 980 ti's but it for the rest of the gear it seems like a lot of money.
just wondering if I should buy this or if not could you give me good alternatives with out a premium price.

case: corsair 900D
only water cooling two gtx 980 ti gigabyte xtreme gaming

Here is the setup:

Water_Cooling_Setup.jpg


As you can see I placed the fans above the Radiator instead of placing them below, and I placed them in pull config so that the air is pulled through Radiators and is pushed out of the case.

I also threw in one or two fans at the bottom so to satisfy the needs of Radiator placed at the bottom. With that there is no need of air to be passed from above.

I would recommend you to use soft tubing.

(My drawings are not great so if you have any doubts regarding it ask me)

im unsure if you've looked in to this in the past, but custom loops can easily be this expensive or more. do you intend to overclock the cards? do you need it to be watercooled? i would also plan this out, where you intend to route the lines and such before purchasing to be sure what you have. i also do not see tubing in that cart or parts for a drain line which i would suggest.

I would like to overclock my cards abit but mostly for slient performance. I know it's going it be alot of money but I would like to save as much as I can. Also I forgot through tubing I will update the photo later when I'm on my pc.

Custom-water cooled loops are more noisier than normal air cooled ones. But that depends on how-many and what kind of fans you wanna use.

I would recommend you to get 2 x 240mm RAD instead of single 480mm RAD. If you get 2 x 240mm RAD then you can provide one ride per GPU setup which is better performance wise as well as quieter.

How is it quieter than 480mm setup??
The heat accumulation from the GPU gets distributed among 2 radiators within the loop which makes the coolant less hot and easy to be cooled. When you have single RAD then the heat accumulated from both the GPUs get run through it at a time which stresses it and needs lot of airflow to get cooled. Lot of airflow requires fans at highest possible rpm which leads the fans to cause lot of noise. If there are 2 RADS the heat dispersion of individual GPUs gets the temps to lower standard which are satisfied by fans running at lower rpm(silently).

Setup:

RESERVOIR ---------> GPU -----------> RAD -----------> GPU ------------> RAD -------------> RESERVOIR

Only three tubes will be running up. It wont be messy.

Here are the three tubes that run above GPU level.

1. Reservoir ---------------> GPU
2. GPU 1 -------------> Radiator
3. Radiator -------------> GPU 2

Tubes that will be running below GPU level

1. GPU 2 -------------> Radiator
2. Radiator ---------> Reservoir

Price cut down
  • ■ EK FC980Ti waterblock should have low pressure drop, I use four EK GTX 780ti waterblocks with just Koolance PMP 300 and two 420 rad, you can opt for cheaper pump with 1.8 m head pressure but you might have to use faster RPM fans. EK DCP pump should be suffice.
    ~ US$28-30 minus
    ■ A bit fiddly but you can use precut HD tube + four matching fittings (serial on terminal + two for rad + two for pump top) + four G1/4 plug. Or six fittings (parallel +...two plug)
    ~ US$6-8 minus
    ■ 2*250 watt TDP, you can limit 980Ti power target at 250 watt and use 360 XE with six fan push pull @ 1600-1800RPM.
    ~US$20-30 minus
    ■ Backplate, later, doesn't help much with cooling but damn looks good .
Performance Opinion

  • ■ With your shown parts, I'd say you could crank up to 150% Power target, the full cover water block cools both GPU core and VRM+VRAM with typical 1500RPM fans.
    ■ How much MHz you'll gain with +50% power depend on your ASIC percentile, should you build upon that parts, do share what speed you'll have and please use benchmark tool and post here.
    ■ Worth YES if you do mostly GPU intensive such as OCTANE render or modding rig, do share here the pic. For gaming you can upgrade to single watercooled GTX 1080 such as MSI Seahawk EK.
