Zotac 980ti AMP Extreme causing electrical interference

[Stunted]

So my 980ti has a small amount of buzzing coming through, which is what I assume to be the coils. This isn't a major issue because it only happens during load and usually I have audio playing, however I've now noticed that my KRK Rokit speakers are emitting a buzzing sound now while the graphics card is under load. I know it's my graphics card because the tone coming through the speakers is tied to the frame rate I'm getting in game. Low FPS emits a low pitch tone, high FPS emits a high pitch tone. 

 

So far I've tried swapping USB slots for the audio interface (Scarlett 2i2) I've also tried moving the interface away from the computer completely, which didn't help. I can only assume that somehow this electrical interference is somehow effecting my USB ports and then travelling through the audio interface into my speakers. 

 

Does anybody have any idea how I would resolve an issue like this? The 980ti has a 5 year warranty so maybe it's worth an RMA?

This didn't happen with my old GPU. I have a Corsair RM750.
