Hi Invisibleblue,
There are some capacitors that has a little gap in between that causes the noise. These unfortunately is very hard to resolve as those are components that AMD approves for manufacturing. We have found that if you cover the tiny gap with a special glue it does minimise the noise a bit, not entirely and it is a painstaking job.
Based on your description I do think is better to RMA the card, please send a mail to [email protected] and send us your serial number and the description of the problem. Proceed to RMA the card through the shop where you bought it and we will replace it accordingly. Noise beyond what we consider normal is not acceptable.
We do apologize for the inconvenience caused and hope we can resolve your problem as fast as we can.
