Bit late at night but the coilwhine seems to be getting better!
I played this
https://www.youtube.com/watch?v=Ktbhw0v186Q while i was gaming to hide the noise but when i muted it the coilwhine is not too bad anymore.
I think the bedding in thing kinda works? I was only playing COH2 so nothing massivelt demanding, max FPS was like 150 but the coilwhine really has died down! The Evga just stayed loud forever...
Maybe the song lulled the card, i dunno. The Evga card kept freezing too, i put it down to Nvidia drivers in COH2 but this card doesnt, so i think the Evga has other issues than coilwhine.
Im gonna keep a hold of this i think, ive also ordered a surround sound headset lol! Just for backup
