I bought my card five days ago and i have the exactly same problem.
I start render the fans spinning up and you can hear the noise. Its a metallic sound so if anyone says its a coil whine is lie.
Plus my card sometimes rattling in idle state. I have two VGA one for display and this new one to render so most of the time this card is just sitting in my case and wait.

As what was said before, a good quick fix would be to place a thin strip of whatever between the fins at that particular location to prevent the rattling noise. A couple strips of electrical tape would probably be perfect for the job. Though, I completely agree with the OP and everyone else who has had this problem that you shouldn't have to do these things when you are purchasing a $500+ GPU (or any GPU for that matter). The good thing is, now that you have posted your video of the exact problem, now everyone knows why it is rattling in the first place. And hopefully the video gets passed to EVGA so that they can fix it...
 
In the end, I'm glad you finally got an ACX cooler with fixed fins.

I had this problem with a Gigabyte Windforce cooler as well. I just went back to a reference model for my next card.

This problem is very common!! I just sold a 780 ti acx which had it (managed to fix it with thermal tape). I'm now running 780 Classy SLI. One of them you can tell has the fins close to the connectors loose. Both rattle and some points. I guess we have to live with it. Amazing cards otherwise.

Yep, crossing fingers that if I step up pretty soon, the problem is non-existent in the GTX 970/980.

I had a similar problem, but it was caused by me (I think some other people should fess up). With the fans running full blast, I was fooling around in my case and brushed up against the blades by mistake. I didn't realize they were so vulnerable. The fan noise and vibrations started immediately. I saw earlier this year that EVGA was selling ACX coolers, but at the time I investigated, they were sold out.

It could happen. In my case the second Classy already came like this. Some of the fins close to where the Pin connectors go are very very flimsy. I'm not sure if the sound comes from there though. Either way. Since i'm running SLI, the sound of all the fans kind of muffle the rattle.
 
Either way, i think the quality leaves a lot to be desired. This shouldn't be happening in the first place. 
 
Other than that i don't think there's anything to complain about this excellent videocards

With all due respect, there's nothing to "fess up" to here for the specific issue we're talking about here with loose fins on the cooler. If you actually read through the entirety of this post, you'll see that the issue at hand is not user-induced, and is the exact same *reproducible* issue narrowed down to loose fins that's out of our control. We're not talking noisy fans themselves, nor are we having noise issues from any wrongdoing on our part; It's simply how they behave.  If you had a similar issue that you admit you caused, fine, but it doesn't mean that the rest of us here are in the same boat. Saying that we have something to "fess up" to is simple victim-blaming, for lack of a better term, in this situation.

Don't let the trolls get to you. 

I never understand why some people always side with the company when an issue is being reported about a product. It's impossible that i have caused this problem to two different videocards. It's too much of a coincidence that many users have reported a similar problem (there are many threads about it). 
 
I know i can fix the problem with thermal adhesive tape. I just don't want to go through the hassle of opening my new videocard, cleaning the old TIM, taping the fins with adhesive tape, reapplying TIM and hoping the noise is gone.
 
This problem is making me consider moving my case to the floor (currently it stands next to me on my desk).

They need to show the actual cooler in detail. Hopefully they have addressed the rattling that people are experiencing.

I tried the tape fix as was suggested on another thread. It worked for a few days but after a valley benchmark the card began rattling again( must have loosened the fins) I had enough at that stage and returned it for a direct cuii. Received it today and so far I've had no issues with rattling or anything else. It also runs quieter at idle as far as I can tell. I'm happy I exchanged it, I personally couldn't be bothered dealing with the hassle of returning 4 cards to get a non defective one. Glad to hear you finally received one that works 😀
