i started a similar project and im having a hell of a time getting the tubing off the barbs. is it really worth the effort instead of just cutting them and losing the 1/4" or so ?

thanks for the tips. I'm almost done putting my loop together now

You think a single 670, using it's standard 120mm radiator would be enough to cool both cards if I added a EK Universal VGA block to the second card and built a loop around that? Might have to turn my fan up just a tad but I figure even so, both cards might be kept in the low 60's fairly quietly.

Any thoughts?

Again, nice guide ...

i would go with the second 620. you only have to run one pump if you combine the loops. i think you would be pushing it with only one rad for both cards

One of the things I am trying to do is find a method to measure the flow or pressure for a dual loop with a combination of pumps running. I didn't see a difference in flow during my initial test setup when I had 2 rads with 2 blocks running in both single and dual pump configuration. That isn't to say there is a difference though.

I would say that a single 120mm rad is enough to cool 1 GPU effectively. I would recommend a 240mm radiator to cool 2 GPU's, however if I were to get another GTX780 in my loop for SLI I might look at a universal GPU block myself to expand my loop. That is still with two 120mm radiators though at the minimum.

In guessing, a single 120mm rad would probably still provide better cooling than a Air Cooler, and be more quiet as well. I think the delta difference would be getting pretty close though. Your overclocking head room would also diminish.

I'd like to also get another 240mm radiator to see how far these little Kuhler pumps can scale though

i have one kuhler pump running through 7x120mm of radiators lol. flow looks about the same
