Crossfire (EK link question).

[Five.Stars]

OK, decided to add a 2nd 7970 to my system (as well as a bit more rad), and am looking in to the various fittings. I think I have made my mind up to go for plexi parallel EK link (as seen in picture - taken from the poster tribz build - very nice by the way).

Anyway, due to the way my loop runs at present I would be interested if a fiiting exists that would allow me to run the water in in these directions - if such exists?

From that pic it doesn't appear to have a port on side left, but is it possible to get a fitting with a port in this position. This would be ideal as I have a Koolance QDC sitting supported by the Antec P280's water cooling entry/ exit points, so if I could run the tubing straight in to fitting from my external rad it would prevent any kinks and just look generally tidier.

Am I right in assuming with a parallel link as long as the inlet and outlets are parallel to each other, then it doesn't matter if inlet is on bottom?

If that is a correct assumption, then I could also do something like this:



Would that work properly with the water coming in at bottom via a 90deg rotary, and out at top back to bay reservoir?

My loop currently goes res > cpu > ext. rad > gpu > res

My new design would go res > rad > cpu > ext. rad > gpu's > res

Thoughts?

I think parallel refers to how much water each block gets at once rather than the position of their in/outs, they each get 50% of the water whereas with a serial one the first block gets all of the water and then the next block gets it after that. The benefit of parallel is with weaker pumps (like mine) that don't have to do as much work.

There is a specific inlet/outlet arrangement for parallel links (and possible serial), the PDF installs guides are on EK's site but I cant say I've seen an in/out in the guides that work the way your looking at.

Hope someone else can jump in and give you some more help

For best flow you want a Parallel flow block for dual cards with the correct spacing for your board.

Yeah, I am working on that basis and my 2 x16 slots are 40mm apart, so I think the link I need is a dual slot link.

Would the water going in at the bottom and returning to the res from the top of the link as shown in pics (or attempted to ) pose any problems. In theory the flow is still going through both cards although admittedly in the opposite direction than would normally be the case.

In my head I can see the flow going through both cards, but admittedly I don't have a freat understanding of how the flow works in a multi-card setup and am still getting my head around it.

Apologies for the noob questions, but I am fairly new to water cooling in general and a complete novice with multi cards.

Cheers.
