Noob Question About gpu Cooling

I have two 5850's in crossfire.

I want to watercool them, but I have a question about whats the best way.
I was thinking about splitting the loop and cooling each card individually they are going to be the only components cooled; It'll be:

res>pump>split>5850's>split(back2single)>radiator>res.

Is this a stupid idea, or feasible ??
should I just make it a single loop setup?

thanks in advance

Running them in parellel or series will make little difference in temps and performance.

It's still a single loop by definition as we define it. One rad, one pump, one res, the water is all the same is a single loop.
You just want to split the water on the GPUs, but it's the same water. Same temps within 2C anyhwere in the loop, even before/after the rad.

Running them in series is cheaper, less parts. Running parellel, you have to have TWO connections between each card.

Look at this link, scroll down halfway. I'm using the Danger Den SLI (Xfire too) fitting. In on one block, out therough the small fitting (the DD SLI/Xfire connection) to the next card, and out on the second card. Works just fine.

Sorry I can't see a link

I'm sorry, thought I added a link. It has ben added to my original post. Hopefully you know about heatload, rad size, fannage and general WC already.

BTW, welcome to OCF!

He might be using an asestek liquid cooling systems
we never know lol +_+

Make A sig --- at the top of the site under the blue banner u will see USER CP -- click -- signature---- Thanks

Or u can just post your WC parts :0

I actually don't have the cooling for the cards yet. At the moment they are using the stock fans.

I'm thinking about going with Koolance parts:

good ?? bad ?? ugly ?? lol
let me know what you think

thanks guys

EDIT:
I don't know a great deal about water cooling actually, that kinda why I'm here; any help would be awesome. I just know about Wattage and CFM and flow rate and thats about it so far.

The pump/res setup is pretty weak. The rad in tests is meh.

The GPU block isn't bad. Seen Danger Den, XSPC, EK waterblocks, they are good alternatives.

Get a Laing D5 and a Swiftech Micro res or a Laing DDC3.2 and an aftermarket pump top.

And the 1000 watt dissipation is just marketing crap. I hate Koolance for even saying that.
