Two SLI links??

[RJF049]

Can I use two SLI links between two cards in a loop like this? Or would that affect the flow negatively? It would be for aesthetics purely.

Wont make a difference

It will lower the pressure in loop, i would just use one to get maximal performance.

Ooooh so probably not worth it..thanks!

Lower the pressure? No. It would not lower the pressure at all. The pressure would not change.

Will it make any performance difference? Debatable, but even if it did, it would be almost unnoticeable. Like 1-3C at most.

I would use something like this

Thats only for EK blocks. I am using two Alphacool Nexxos blocks. Thanks for the suggestion though!

I didn't think it mattered. Thought it was compatible with any blocks. My bad.

It's called parallel flow and if you use two connectors it keeps the temps of the GPUs more similar. Overall performance in the rest of the loop may increase slightly as the water can flow slightly fast but it wont change much.

sorry guys, i was wrong

Whoa, did not think of that.

If the goal were to be to keep the GPU's as similar as possible, which setup would be preferred? 

This one: 

Or this one:

Sorry, could not find a picture. Hopefully you get it. This setup would allow the other link to be for the coolant to flow on it's own between the two GPU's.

sorry guys, i was wrong

It is ok. You are learning.

[VAITO]

Shouldn't make much of a noticeable difference but highly increases the aesthetics imo

That would kill your GPUs.

That does not make sense to me. Why?

[Dr3nz4r]

why not use something like a dummy SLI link?

That is quite an idea. I like it.

[CaSsE]

you wouldnt have any flow in both cards because the water would go straight from top to bottom.

I understand now. 

I imagined it as if there is a connection to where the coolant can flow from one port to another on the same GPU without going through the part of the heatsink that is over the heat spots. 

In other words, that it could flow freely without touching the GPU's in parallel, regardless of orientation. Obviously I am wrong on that and now understand why (in the picture I post, it has to go through one GPU or the other and cannot bypass both at the same time, whereas it can in the setup I had)

I may run a test or two on my GPU's with that other setup just for the lulz. Underclock as all hell though to prevent them burning up.

Would it matter which outlet the water came out of the bottom card?

[Vitalius]

Would it matter which outlet the water came out of the bottom card?

No, as long the inlet that the water comes into is on the opposite side.

[RJF049]

No, as long the inlet that the water comes into is on the opposite side.

Which one would that be though since i'd be using two links on the top?

[Vitalius]

... No. You are using 2 links in the middle. The top (where the inlet is) only has one connection. 

Such as your picture:

That is perfectly fine and it does not matter if you swapped the inlet and outlet's positions (such to where they were connected to the other port you could use).

[RJF049]

Thanks for all the answers guys. This forum is great.

Ahh that makes sense.

You may want to try to fill up a SLI link, so the coolant wont flow through, just like a blocked tunnel. So you basically got 2 Links with one of em being a dummy. Im not sure but i think i've already seen that somewhere done with liquid rubber used to seal the "Dummy" Link. There are a few other methods i guess
