Custom Water loop for 2x 980's in an Air 540 (feedback and suggestions)

post #1 of 7
Thread Starter 
Hi, i've been sitting on my new PC for about 2 months now. I've always wanted to go for triple monitor and i've been thinking alot about getting another 980, simply because one would not be able to keep me on 60+ fps. The issue with 2 air cooled cards in my scenario is that i don't have a 1 slot spacing between the cards which will mush them together making the top card not able to breathe properly.

I've overlooked several kind of setups for my case and i've been theorycrafting for a while. This is what i came up with.



- One thing that might be a problem is the Res+pump combo unit below the 2 cards, it might not fit.
- Another thing i thought of is the 140mm radiator thats runs in the bottom, it will be placed directly above a HDD. HDD runs hot and so will the RAD which is not good.
But i've thought about getting a custom 3mm Aluminum Backplate that dissipates the heat which most likely will solve the problem. There will also be a spacing in between the RAD and the alu plate.
- Also not a 100% sure that a 140mm+360mm RAD will be able to cool 2 980's, but it should be enough? right?

Solution for everything would be getting a new CPU block and a 240 RAD to replace the H105 which definately will be enough to cool the whole system, but more expensive and i'm already satisfied with the performance and look of my H105.

I'll appreciate any comment giving advice/feedback or suggestions!

You can get away with just the 240 & 360, especially if you're going to slip push/pull in there. I would skip that radiator on top of the hard drive, nothing good is going to come from that. I personally ran my res up the back, in front of the video cards.

Picture for reference:

What graphics card do you have and whats the height of it? thinking about the clearance for the Pump+Res. That way you got it is looking good.

That picture is of 2x290x's. I now have 1x980Ti in the exact same config, so that 980 will work.

Edit: Also, for people looking at that and wondering, it's stupid easy to service. Drain loop, loosen the inlet fitting ontop of the res along with the outlet fitting, and it slides right out; Takes me long to watch the loop drain.

Which make is the 980ti though, they tend to have custom PCB's if it isnt a reference card. mine has a 118mm height and it looks pretty tight.

Apologies, mine is a reference. EVGA ACX2.0+ SC+, which now has a Titan X EK water block on it.

These are the listed dimensions, which obviously include the cooler which I don't have on: Height: 4.376in - 111.15mm Length: 10.5in - 266.7mm

Edit: The 290x dimensions: 12.01" x 4.45"

hmm, my pcb is 118mm, the card is about 145 with the cooler on. might not fit there :/
