I put a lot of my water cooling observations in the Classified owners thread: http://www.overclock.net/t/1411500/official-evga-classified-owners-club/1330

But right now I'm running a pretty stable 1400core @ 1.3 volt. Anything over 1400 requires a lot of extra voltage, and you'll start seeing artifacts around 1436-1450.  Also running skyn3t's custom bios which gives me a 130% power target. Highly recommended.

I ran the 2nd highest Valley bench score for a single card earlier (top card being LN2 Titan). Beating out tons of Titans, 780s and SLI 680s. The Classy is just amazing

Thanks!  Will try to keep the card around 1300 I guess for 24/7 use.  Anything higher will just be for benchmarking.

I have been running Blacklist at 1306 on both of my 780 classifieds on water.  My guess is I will need a customer bios to go any higher.

Great to hear!
 
Anymore info by others would be great!

I have same issue though at different speed. other people have report noise issues aswell. I think if ur rig is quiet enough its sticks out, maybe some people dont hear an issue with theirs or they dont have an issue. but it seems common enough that if i were u, i wouldnt worry about it. Just try setup up a fan profile that skips the fan speeds that cause the rattle/vibration.

I posted a link to a skydrive file of a vid i made. Compare ur noise to that. Here is the link.

Hi,
 
I checked your video and sound is not really same but same effect. When fan is running 40-60% it's making that noise. Maybe I need contact Evga's support and ask what I can do. I think that if I send now my card to Evga, I need wait new card.

Hi again...
Now I recorded that sound and this sounds the same as the other.

In that file I am running fan at 45% - 57% - 80% - 90% - 100% and automatic 29%.

Can anyone from Evga confirm that there is something bad batch left for sale? And if I make RMA I can get new card?

Hi,
 
Copy that on your browser and remove those spaces. I have under 10 post so, I can't post links yet.

Ah ok link works now.
 
That rattle sound is the same as what i get but u seem to get it more often. the sound of the fan motors sounds different than mine thogh, i would go so far to say its maybe a softer noise. So i can understand that rattle/scratching noise being annoying.
 
Would be nice to get a response from a EVGA rep as to the cause, maybe its somthing that can be fixed by the users.

COOL BUILD
 
Thanks,

UPS just dropped off two Hydro Copper 780 Classifieds and an EVBot, you guys think I should open them? They would need to run like 1500 MHz to top my 1.3v Titan's.

1500 really isn't feasible... especially in SLI. Based on what Crezno said earlier in this thread and my own experience, it's gonna be tough to run much higher than 1450 stable. 
 
I did a suicide run earlier in Valley @ 1463, but it was no way gaming stable. Artifacts start showing up right around 1450.

It's really bad having such 1st world problems isn't it Cial? :)

 
haha :)
 
cheers on beating my Valley score you bastage!

I need a way to lower the temps on my classifieds besides watercooling them :x. You guys think I should replace the side panel fan for a better one? I'm using the cooler master haf-x.

What's your ambient temp and how hot do those cards get in that case?

My cards idle at 50c with my fanspeed at 55%. I currently have my voltage bumped up to 1.2.

What's the room temp ...

What did your 580 Classies idle at? Were they hot also? The reason I ask is because your Mods Rigs picture looks good on cable management but you have to remember these blow the hot air inside your case which you already know :)
 
The only thing I can suggest is replacing your TIM and that might help temps. It brought my temps down 5c on load but only helped 1c on idle and that would not help you here with your idle temps.
 
Are Both cards idling the same temp?

Here is what I would do if I was in your shoes :)
 
1) Replace the thermal paste because that always helps. These are real easy to do that with. Have you done that before?
2) I would try both intake and exhaust and see which is better.
3) If you don't want to go WC'ing and nothing works that we have talked about than the only thing I can see to do is get a new case. There are some really nice cases out there that are not alot of money that would get that hot air out of the case.
 
Note*** The reason I would change the TIM is because I remember with my 680 Classies that one of them had a really poor application and when I changed it my temps dropped 12c. Yes.... 12c but from what I see here (along with when I replaced mine) and on other forums the application process was nicely done -- a little thick but nice. But you have to remember no matter how nice the application it still comes down to the TIM used and how thin the layer is ;)

I've never replaced the TIM on a gpu before but I've always wanted to learn/try lol. What TIM would you recommend? Also if I were to get a new case what would you recommend? I like the Corsair 800D but I feel like I would still have temp issues lol.

jimrun is saying your cards are running 25c Above room temp...
 
I always use MX4 for all my needs. That is just me and others will say different but it all comes down to what you like. I like MX4 because it spreads nicely and removal is easy and it does really good with temps. 
 
My opinion would be to not get the 800D case. It really is not good for your situation.
 
I have go eat my din din (my other half is calling me) so I will look at some cases after I stuff my face LOL and will get back with you.
