No I haven't yet as I'm still waiting for the refund from the Gigabyte. This doesnt sound very promising though... I was hoping mine was a one off, unlucky card. However customer support from overclockers has been good. I'm hoping the next card will be problem free.
Well I'd watch yourself. Looks like I'll be returning mine on my own dime as they're not willing to accept this as a faulty return due to the whine at ANY audible range...
