Just keep it if you can live with it, if not only real option is watch what people say regarding different models and AIBS what their cards are doing, sending it back for same make and model will only come back same or worse or a little better and not worth the hassle. If you like the look of the card and the card you wanted for the looks then keep it, SUPRIM X seems to do this so far and I only have used one and it does it 100% at levels I have not heard before from previous gens apart from broken cards or the silly high oc ones like the KINGPIN 3090s that were comical for their coil whine.
Check this for coil whine on the kingpin 3090..
