Hi there!
I just purchased an EVGA Geforce GTX 780 SC with the ACX cooling unit.
When I installed it in my system, there was some issues with the monitores not recieving video from the card, but it eventually solvet itself.
When I, after installing drivers and such, tried to load the card with MSI Kombustor, it started whining like crazy. It's a high-pitched, elektrical noise, and I'm pretty sure it's coming from the graphics card, since it's only apparent when loading it with Kombustor. I tried launching a game, which worked just fine, but there was, instead of a whine, a buzzing noise.
Here is a list of all the components in my build:

CPU: 3770k
GPU: EVGA Geforce GTX 780 SC ACX
MB: Asus P8Z77 I-deluxe/WD
PSU: Corsair CX 750M
Boot drive: Samsung 840 PRO 512GB
Storage: WD black 1TB, WD green 2 TB
CPU Cooling: Corsair H55
Some noctua case fans.

Do you agree with me when I say that it's the GPU that is coil whining, or do yuo think the PSU is coil whining?

I get the exact same with my Asus GTX 760 (my psu is an Antec 520w), it squeals when it renders at very high framerates and a slight buzz when playing games at 60 fps or so. You can always use adaptive vsync in the nvidia control panel for games to avoid excess frames.

I had the same thing happen to mine, I bought one video card with the acx cooler and then a 2nd a few months later. It's just the card, I noticed that it did whine sometimes during heavy loads, but for some reason after about a week it went away. I noticed that on both of my cards. What you could also do is launch a game and have the case cover off and stop the fan while you hear the noise to see if it is the power supply

So are you saying I should RMA it, or just wait and see?

I guess you could, but there is no guarantee that you would get one which doesn't have it :|
(Ugh sorry I'm in the same boat and frankly just as confused I guess)
Have a look at this EVGA forum post, they have a similar problem

Okay, so I see from that thread, and from googling the issue, and finding other people that had the same problem. Those people said it went away after a while. Should I expect it to go away? Is the card broken in any way because of this noise?

As long as you aren't seeing any artifacts or performance issues it probably wouldn't be broken. If it can run games for a few hours under load then it should be fine for the most part. You can always contact EVGA and ask them for some advice. Good luck :)

What do you mean by artifacts? How can I check for performance issues?

Okay, thanks so much for the help!

Okay, so I've run 3dMark now, all three tests. On the first two tests, there was no buzz noise. However, on Fire Strike, the buzzing noise was there.
Here are the scores I got: http://www.3dmark.com/3dm/1390136
Also, on the last test in Fire Strike, the combined test, I got around 18 FPS. Isn't that very low, considering it is a GTX 780, and it's overclocked to the limit?

Sorry mate I haven't played around with benchmarking software like that, but looking at the run details, your firestrike score is still higher than most pcs, only trailing behind a titan system (which the 780 is very close to anyway). In regards to low fps in that I'm not sure...
These guys don't have too much of a clue either lols

Hm I wonder what settings you ran with firestrike because from this:

http://www.fudzilla.com/home/item/30371-3dmark-fire-str...

I see "For high end gaming PCs, only the Fire Strike benchmark test is relevant. Using Fire Strike's Extreme preset is a good way of making high-performance PCs cry for mommy. The extreme preset is a full DirectX 11 benchmark made for high-end systems with multiple GPUs and it is not available in 3DMark Basic edition."

Do you get low frames in any games? I wouldn't personally worry too much about a demanding benchmark :|
