Hi.In the last 3hrs I bought and installed a Gigabyte HD7970 OC, 3G. Performance is pretty great so far but I've noticeda rattling noise when the card is working hard.
It's not the fan, if I manually raise the fan to 100%, the noise doesn't happen, it's only when the card itself is being pushed hard, like Far Cry 3.
A quick google around and I'm pretty sure that what I have is 'coil whine'.
This can't be right for a top of the line card! I'm a quiet PC person. I've spent a fair bit of cash on quiet fans etc so this sound is maddening!
Is this issue covered by warranty? If I return my card (brand new!), will the next one have the same issue? Will this sound go away?
Thanks for your help.
