I was able to hit 940 on both my 580's with Max voltage...1.138v....haven't bothered with Furmark, but Max Temps I saw in Vantage were 67C ..Air of course. These 580's ...even on air are incredibly cool...both mine idle at 27-30C.....

Got my EK 580 block yesterday, did a rig teardown, install, and cleaning today.

Before I was hitting about 85-88 load at 850mhz 1.038vCore . After the waterblock? A chilly 50c running at 960/1.138Vcore! But the best part? No more blower fan whine

Now, the temp does go up to about 55c if I'm running 100% CPU and GPU (folding both) since it is in the same loop as my 970. Might be time to consider another rad or a better set up, too. My CPU went up 5c adding this card to my loop. Seems an OC of the CPU and GPU to its max is just about all this setup can handle, and is actually limiting my overclocks any further. CPU is at 65c (Cores at just under 80c) so I really cant go any higher with the volts or overclock.

It depends... if your watercooling for low noise yes it would be quiter than air.... but if your watercooling for performance it can get rather loud... 2000+ RPM fans attached to your radiators...

Like vohiep84 says, with liquid, as with air, you can do an extreme cooling build or an extreme silence build. It really comes down to the radiator / fan combo you choose.

If you want a silent build, you will want to liquid cool the CPU, Mobo, and GPU. Then you will want to choose a low FPI (fins per inch) radiator and use low RPM quality fans. Then, the loudest part of your system becomes your PSU and your hard drives. For my current build I liquid cooled everything and used an SSD with WD Green HDDs, and a Zalman PSU with internal heat sinks and in a perfectly silent room it is barely audible and really it is completely inaudible from over 10 feet away.
