Watercooling SLI. Need parallel bridge.

[XxKINGxX40]

Hey guys, I am going to be watercooling my CPU and 770s. I want to get a parallel bridge, but I don't know which one I need. I was looking at one like this:

Which bridge do I need? This is how my expansion slots look.

(The Xs are where my GTX 770s are)

 

Which parallel bridge do I need? Thanks.

The one you linked is designed for two cards 'back to back', so to speak.

 

This one is the correct spacing, but is CSQ: http://www.frozencpu.com/products/16697/ex-blc-1186/EK_FC_Bridge_Dual_Parallel_3-Slot_CSQ_-_SLI_Connection_-_Acetal_EK-FC_Bridge_DUAL_Parallel_3-Slot_CSQ.html#blank

Is there any particular reason you are going with parallel over serial?

I've always read that parallel reduces your flow rate significantly.

parallel also can give you problems, ive seen 2 posts about in the last 60 days about people having 1 card being at 90C while the other is at 30C with parallel loops.   cause if there is any difference restriction between the 2 blocks 1 wont get flow, they both had air in 1 block.

 

 

serial is better.

That makes no sense, with parallel flow all cards should be within 1-2 C of each other. If there was air in a block, it is not the fault of a parallel flow configuration.

[Prophet of Entropy]

air pockets with serial connectors are very rare compared to parallel, and my serial SLI cards are within 2-3 degrees of each other under load. so... why go parallel?

[VSG]

I am saying a properly bleeded connection, serial or parallel, should not have air pockets. So blaming a configuration isn't right. I agree that the likelihood of air pockets is higher with parallel than serial.

In my case, I went with parallel flow with two cards because I still had 1 GPU flow and my second KPE could get pretty hot if in serial.

For 4 cards like the OP has, neither is good by itself. Parallel flow will reduce individual card flow a lot while serial flow can raise temps on the last cards more than necessary. A semi-parallel flow is best here with the first two cards and the last two cards in parallel within and connected serially. Take a look at the EK quad terminal to see if that works for the OP.

[Prophet of Entropy]

from what I can tell from the OPs chart he only has 2 770s.

Ya, you are right. I mistook expansion slots for number of cards.
