Hi, I have the X850XT and downloaded the ATI Tool. I wanted to change the fan speeds and while I was checking out the other tools this loud ringing noise started coming from the video card. I'm not sure what I did do produce this noise but I am sure it happened while using the Tool. Anybody know anything about this and what to do to fix it? Restarting doesn't do anything and I changed the clock settings back to default and it didn't help.
