I have an EVGA 1080. Over the years, I've had several EVGA cards. Every time I play a STALKER game, it always produces coil whine, on every card. It's never been a problem. I believe coil whine is totally benign and nothing to worry about. The only thing I can suggest is to make sure your PSU is delivering enough power to the videocard, and that it's being cooled well enough. If the noise is just "bothering you" then contact Asus (or Newegg, or wherever you bought it) and see if they'll work with you, to possibly get a more quiet card. But you'll probably still have some whine.
