If I recall correctly, there was some talk of bottlenecking with an i5 and crossfire 7970s so I might be experiencing the same thing. I don't notice anything while gaming though, but that isn't exactly an objective measurement. I think when Ivy releases, I will be upgrading to the 2600K version of that or even the Sandy-E line if I'm willing to splurge at the time and if Ivy ends up not being so great.

i5-2500K with 680 OC (Power Target 100%, +150 Clock, +300 Memory, 68% Fan)
700
As you can see, I really can't seem to overcome the minimum barrier even with an OC. But it stays at the minimum level for less than a second during the early part of the benchmark.

I'll update with same tests on a sb-e platform friday/saturday, very nice setup you got there like I've said.

NinjaNaren - Hey no thread hijacking! wink.gif Lets stay on topic.

So it appears some people have heard coil whine (as in the video linked in the first post) and others (siryak, CapnCrunch10) don't? This doesn't sound promising. Maybe in the next few weeks when more people have them under water we'll see....

Apologies. We'll make a separate thread.

But you're right. Under water is going to be the only way to tell for sure. As far as I can tell from holding my ear against the cards is that there is no coil whine for me for either card or it's so slight that I couldn't pick it up over any other noise being made in my case. The Sapphire ref 7970 I tinkered with definitely had an apparent coil whine to it though so I'm not getting anything like that with the 680.

No one here has experienced coil whine in the thread. I wish Linus actually recorded the coil whine itself instead of just mentioning it. But if your fans spin up to heavy load during an intense gaming session, the fan noise is going to be way louder than anything else.

My 680 has coil whine under load. Not too bad, but definitely audible. Its pretty loud if I run WEI for some reason. You can hear a little flutter when playing BF3, Skyrim it seems silent.

I searched around and asked in other forums. I was unable to get a clear answer as to whether the GTX 680 exhibits coil whine like the ATI 7970 does.
The answer apparently is YES http://www.youtube.com/watch?v=IaPYEOUH7LE at time index 7:30
I did not notice this on my ATI card until I watercooled it and the fan was not masking the sound. I hope this helps others who have been wondering about this.
All you 680 owners out there, perhaps you can chime in and share your experience with this.

Corsair PSU???
