Watercooling OC'd i7 and 2 5870s

post #1 of 6
Thread Starter 
Hey guys, I'm upgrading my hardware and, in turn, my loop. I previously had a Q6600 that was OC'd to 3.0 GHz and a single GeForce 8800GTS all on a single loop with a Black Ice 240 doing the cooling.

Trying to budget my WC setup, I was wondering, given that a single 240 can't hope to keep the new hardware cooled as well as the old, if another loop or (hopefully) just a another radiator would be enough? Maybe use the 240 and a 120 in conjunction along the loop?

Or should I just buck up and do two separate loops? Thanks.

I don't think a 240 + 120 would be enough. You need to look at the total heat output of the components. You didn't mention whether it was a 1366, 1156, or 1155 Core i7, so I'm going to assume it's a 1366.

A single 240 might cover the i7, but I have a feeling the black ice will be close. I'd recommend at least another 240 radiator for the 5870s.

And FWIW: It really doesn't make a difference if you split the loops up. You're not going to see any real change in overall temperatures.

If you could add another 240mm radiator to the loop it would be great, if you can only add a single 120 that's fine too. You'll still get good temperatures, just about 2-3C warmer than if you added another 240 instead of a 120.

Yes, it's 1366.

So it seems the consensus is just get another rad? Separating the loops doesn't equate to that big of a difference?

Yep. Dual loops don't offer any performance increase over a single loop. Adding more radiator will lower your water-air delta and thus lower your temperatures.
