So, I just recently purchased an ACX EVGA 780 Ti Superclocked graphics card secondhand from a gentleman locally. He told me that he had heard coil whine and some rattling from the fans before he took it out of his rig. I figured playing with clock and fan speeds could maybe alleviate these issues, so I bit the bullet as I got a pretty good deal on it.
Coil whine and fan rattle are present. Overclocking, downclocking, ramping up the fans and turning them down does not fix this. I've also changed power supply (no cigar.) I have an approved RMA but I keep hearing about people receiving multiple RMA'd cards that have the same issue (some even worse.)
I'm about to build a custom water loop, and I know that will fix the fan rattling issue (can't rattle when there are none, amiright?) I am wondering however if I could expect the coil whine to be fixed as well. Has anyone had experience putting one of these troubled cards under water and had the coil whine disappear? Should I keep my card, or take my chances trying to get another one sent to me?
My specs are:
Intel i5 4670k (stock)
8Gb of Kingston HyperX Ram (Stock 1600MHz)
Gigabyte Z87 UD4H
Samsung Pro 128Gb SSD
EVGA SuperNOVA 750G2 Power Supply (Also tested Corsair RM850)

The whine should increase as the you overclock and increase the voltage. It's something you can't exactly predict because some cards will whine more than others. Some might not at all. The ferrite-core inductors and chokes will, by nature, vibrate, so I don't know what to tell you. Some people try to minimize vibration/buzz/whine by doing things like applying nail polish or hot glue to the components.
That is completely unrelated to coil whine.

By removing the fans and putting the card under water it will stop coil whine. It will still act like a standard 780 Ti when placed under, just without the whine and decrease temps a heck of a lot so you can OC more.

Incorrect, read what r00t posted. He is correct, because all electrical components will vibrate when a current is applied to it.

That's incredibly helpful, and unfortunately exactly what I figured would be the case. Thanks a bunch r00t & Buxtyy!
