1080 SLI Loop configuration

[AJ847.63]

Hi Folks,

 

I've recently purchased 2 new GTX 1080 STRIX cards and want, well...... need to redo part of my loop to install the second water block just wanted some advice on how I can route the tubes with changing as little as possible.

I've attached a pic to show how I've currently got things done and really want to try change as little as  possible.

Please note obviously the pic is of my old single 980ti, which is being replaced with 2 1080 STRIX one in the top slot currently occupied by the 980ti, and another in the slot below it.

The tube on the left of the GPU is the outlet going to the back radiator, and the one on the right is the inlet coming from the front radiator.

 

I was thinking of redoing the right hand tube so we would go out of the front radiator, tight 90 degree bend to run parallel just behind the fans then come back up and go into the inlet on the left hand side of the 1080 which will be in the second PCIE slot. Then I can go out of GPU 2 up into GPU 1 via a straight piece of short  tube. And then utilize the current tube I already have in place to the back radiator. 

Would that work? Or how would you recommend me do it?

Can you utilize both the top and bottom left hand slots as inlet and outlet for each block, or do you have to use one left and one right?

Oh, BTW, I'm using the 1080 STRIX bitspower water blocks. 

 

Thanks for your assistance!

i didn't read the full post like an idiot, so here's my new reply:

 

because of how flowing liquids work, you can just have the two cards connected like this, 

 (sorry for the terrible pic)

in this setup, you could place the outlet on the cards on the top also, because liquid flows evenly through both cards.

if you do it like that, you could make simmilar bends as to what you have now. if the GPU blocks line up, you might even be able to keep the bends you have now

not really relevant to the question but i love the loop in the 909, I have the same case.

Thanks for the advice. So I could have the loop enter the bottom card and leave out the top of the top card to go to the back radiator? I think that will be the easiest way and hopefully it will line up perfectly so I can re use the tubes.

Thanks. I agree love the look of the 909 looks so minimalist but also so stylish. Shame it's a pain in the ... to build in though! Wish they would remove the back compartment and have it as one open space so I could of put my res in behind of where the front fans are would of looked so much nicer!

 

They need to file down the edges too some of the edges on the inside are razor sharp got so many cuts all over me and god knows what it would to to the cables and soft tubing over time.

 

i wish inwin would do a EATX version of the infinity window 505 I think it's called. Large enough to fit a 60mm thick front rad 420 mm in the front and a 240 at top or bottom would be the perfect  case. Only chose the 909 plus because the others are too small. As it is now I've had to remove the bottom fan off the front rad as the 1080 strix is too long won't fit ?

Hi Guys,

 

Quick question I dont think this will work,. but would it be possible to leave the tubing routing the way I have it in the photo above and just have two lines connecting the bottom and top GPUs?

 

So I'd be going into the first card via the right slot then out of the first card via the bottom right slot and into the second card via the top right slot then back up to the top card via the top left slot and then out of the first card via the top left slot to the back radiator. So basically how I was running by single 980ti build. 

 

Would that work?

Should work, the flow would be split 50/50 between the two blocks.

I'm running my pair of 980Ti's in a parallel config (as can be seen in the V1.5 update for my rig, linked in sig), though kinda in a flipped config to your setup - mine has the coolant going in/out the ports of the bottom card instead of the top card. Either way works though

 

Depending one which slot you're going to put the second card in, it'll probably be best if you grab of one EKWB's FC Terminal blocks like this one - https://www.ekwb.com/shop/ek-fc-terminal-dual-parallel-plexi (READ THE PDF INSTRUCTIONS!) - instead of fiddling around with the HD Tube and Adapter gear they have, as that stuff is a pain to mount 2 blocks with if they're close together (as I learnt the hard way).

You should still be able to keep the tubing as you currently have it routed either way.

Thanks for the assistance. I ended up doing two lines between the GPU getting it installed wasn't too bad i think my MB the maximus VII formula has bigger gaps between the first and second PCIE slots which made it easier. Unfortunately no luck finding anyone with fittings in stock today though so I'm going to stop past a store during my lunch break tomorrow and hopefully they will have enough fittings in stock for me  to finish this thing off.

Excited  and intrigued to see what the temps will be like running the config like this and compare it to my old 980ti. Or even if running these on water will let me oc them much more. I was having big temp issues on air with both 1080s had to have the fans up to 80% to get them below 80c so it will be interesting to see how much the water helps with that.
