WaterCooling and overclocking decisions

seekdestroy · 21 Mar 2011 at 20:44

Ok guys, going to be getting my 2nd GTX 460 card for SLI soon, and considering some sort of watercooling. Mainly because for my overclock I'm being limited by temperatures.

Going to unlock the volts to 1.212v and see how far I can push my gfx card. Maybe try reach 1ghz

Was just wondering how much cooler would be needed for this?

How many rads and what size?

I was thinking of cooling CPU under water too, but I don't see the point as I'm not limited by my temperatures, I don't want to go above safe volts for SandyBridge.

you could get away with a 240 and 120 in my opinion, for my rig (SB 2500K) and 2x 6950 unlocked I use 2 x 120 and a 240 with sharkoon silent eagles and it keeps the gfx @ 49 max on furmark and the cpu doesn't go above 70

Whats your 2500k overclocked to? Cus my temps never reach 65C with my Noctua. overclocked to 4.7 with 1.34v on the core.

So I don't really need anymore cooling for the cpu tbh, cus if I push further I would have to break the recommended voltage limit. Just for 5ghz+

If I was just to cool the 2 gtx 460s, would 1 240 rad be enough?

Hmmm, not sure if I can fit a 240mm rad in.

Would 1 120mm rad cool 2 GTX 460s? I guess not. I'm running out of ideas.
