sounds bad

One of my 780 Classified does the same thing, raising fan speed makes it go away.  Watercooling them so not a big deal to me, but when i was using them, it was pretty irritating.

how do you get rid of it?

I wonder if you can actually RMA it when you have fan noise @ 36% and it goes away @ 41% tbh.

Please contact EVGA tech support

I did, they told me to re-install my graphics drivers 
 
quite a useless tech support I got there ...

when you pay 50 EUR more for an advanced quiet cooler, i actually want it to be quiet...
So when EVGA has a remake of their ACX cooler, I want that RMA...

I made it run at 50% and now its gone.

I notice the fan noise with my classify as well. It only happens when the fan gets to be around 45 or 46%, but the it only last for several seconds since games push the gpu so it goes quickly above the fan 45% fan curve or not require as much gpu power and remains at 40% fan speed. I do not consider the noise an issue.

I have the bad resonance problem as well on the 780 SC ACX  . And this is the 2nd card I got (first was RMA'd with this problem).
 
Will be buying a 3rd party cooler and never another EVGA product again. 650 euros and rubbish fans  Couldn't even sell this on to someone 2nd hand in good faith.
