Hey, my first post here in this section.
 
I'm having an issue regarding the heat of the card, so far i have limited the voltage and GPU clock (under clocked) to make it little more not so hot...
 
The temps are 82-83C (full load) and then it start "throttling" to keep GPU temp in check, i don't want the card to run this hot and as i've seen in other reviews their cards seems much more cooler then mine.
 
First it was 1081.5 Mhz / 1161 Mv - 1174 Mv 
In real life the Core GPU clock was 1162 Mhz at it's peak.
 
Now it's reduced to 1149 Mhz (1071.5 Mhz / 1125 Mv)
 
Changed the "Mv" limit with the help of Kepler BIOS tweaker.
 
Now my concern is since i don't want to raise "GPU temp target" and want the temps down i've tried a higher fan profile, tested at 90% speed and still reaches the "throttling" issue (playing Watch Dogs).
 
As i said above i've seen others with no kind of this heat issue, should i try replace thermal compound or lower clocks more?
 
Since a higher fan profile didn't help me much (nothing to be honest compared to the noise), i'm stuck with these options unless someone else have a better one :)
 
My case is a NZXT Phantom, with relative good airflow and yes my room is quite hot around 25-26C.
 
Thanks for reading, and i have my faith in EVGA forum's part :) 

My case have the standard installed "NZXT" fans which includes 2x 80mm fans at the bottom taking air in at the hard drive's.
 
And 1x 80mm pushing air out (back) of the case, and this fan is good air-flow "aligned" with the cpu cooler Noctua D14 to get the "hotter" air out.
 
Last fan is on top 1x 200mm pushing hot air out of the top, the side panel has a "grill" so when the graphics card is in full load i can feel the hot air just bursting out of the side through the "grill" (placing for 200mm side fan)
 
I haven't tried yet taking the side off, maybe it will help.
But in my opinion the air-flow is relative good, and as i said above the 780Ti ACX Classified just burst hot air through the side ventilation.
 
Thanks for fast reply.
 

Don't really like having the side off, and my space is limited since i have the pc up on a desk right next to my screen.
 
But these high temps are really annoying, isn't so much of a fan to water cooling but if this is the way to go i might have to reconsider my thinking.
 
Had a EVGA GTX 780 SC ACX before, worked great at 74C as max, this card just makes me sad.
 
Thanks man! 

Ok, gonna try it tomorrow have some Noctua thermal compound left.
 
It have always worked good so far for me on my builds and given nice results, no problem with using it on the graphic card i hope...
 
After i have tried with taking the side off, and there is not much improvement.

Hey again, i have done some tests and i have some news and updates.
 
First off i have changed the thermal paste on the GPU (Noctua NT-H1) and everything went fine there i'm pretty sure.
 
Pics:
 
The pc, with the side removed.

 
Side panel, with the fans and "grill" i mentioned in my other posts.

 
The card disassembly, with old thermal paste.

 
Close up on the old thermal paste.

 
 
Removal of the old thermal paste, nothing special.

 
And here is the new thermal paste applied, i used a "credit card" formed object to spread it out.

 
Finally all put together and back in the case.

 
I know it's maybe many pictures, but i thought it would be funny to share my progress.
And if anyone have a opinion, or how i should do.
 
The temps after the replacement of thermal paste seems to be better then before, used a more aggressive profile for the fan and it seems i have get my first result of success! :)
 
This was with the side off, and my room temperature was 26,7C at the moment testing took place.
 

 
In this picture you can see that i didn't hit my 82,5C temp limit that the throttling starts and my first proof of improvement after changing the thermal paste.
 
The stress test i used was Crysis 3, and it run for about 30-40 minutes.

 
But after all this a problem occurred, when i first ran the tests everything was normal and that was about 2 hours the pc was on without any issues.
And the problems that occurred was that the pc froze and nothing more to it, i restarted and tried again but same thing.
 
Tried restarting and entering "safe-mode" and that was successful without any issues at all.
 
So after that i thought hmm how about i change the BIOS in the graphics card to second and try again, and now i haven't had any problems so far.
 
Since i have a flashed BIOS i tried that and working so far (~60 min), should i flash back to the original bios?
 
I'm tired of errors and high temps -.-
 
I know this post is a bit long, and i appreciate the people reading it and trying to help me!
 
So Thank You, and i hope i get this solved.
 
 
IMPORTANT UPDATE:
 
Turned out that when i should upload one more photo, my iPhone cable was broken and caused the freezing and shutdown of the pc.
 
So i switched back to the flashed bios and everything works fine!
 
And this also cost me 1 USB 3.0 port during investigation (R.I.P.) :(
 
I have x2 120mm lying around, any good suggestions on how or if it's worth applying them for use?
 

Reply: haris525 Hey, yes but my card idles perfectly on low "usage" (324 Mhz).
 
I'm thinking about upgrading my GPU cooling to Kraken G10 with Corsair Hydro H55 since it's 120mm fan and radiator so it will fit in the back of the case.
 
I saw in another thread that it should be possible but the VRM plate must be "customized" to have the cooling (Corsair H55) unit fit perfectly to the GPU with the VRM cooling plate under.
 
Since as i have seen, they get really hot and as my self i'm afraid of "heat" issues so does anyone here think this upgrade is an good idea for my heat issue?
 
I have heard allot of issues with Corsair's cooling units they seems like a "lottery" and many have problems, is it worth it or should i get another brand such as Kraken X40?
 
Refer to this thread: "Is Kraken G10 Compatible with 780 ti classified?"
Can be located here in EVGA forums part.
 
EDIT: I'm very skeptic to closed water cooling since of the leakage issues that CAN occur, and failure rates.
 
 

If I were you I would move the top fan over 1 spot. All those fans together in a confined space could be creating negative pressure. I would also install a nice 140mm side fan blowing directly onto the card. (ie... Noctua, Cougar, Corsair)

Hey, ok thanks for answers!
 
Yes i have ordered the Kraken G10 and Corsair H55, and with some new fans since the cooler master are way to loud.
 
But if i put it this way, a closed loop cooling what is it's life time to be expected around (between failures).
 
Corsair do have a nice 5 Year warranty so, i guess somewhere around there +/-.

 
Should be better than 5 years, but if not, and you notice your temps climbing, look into RMA.  make sure to keep the screws you remove from the cooler so you can easily replace the stock cooler if necessary for any reason at all.
 

That's smart option Kraken G10 is not for Classified card,
only can destroy look and hole experience and with water-cooling difference in temps will be huge compare to any AIO or aftermarket cooler. 
I need to order these days CPU/GPU block, pump and two radiators, and fittings.
Than after that only few little things as thermal pads and temp sensor, and few things more and than easy.
