I recommend that you remove the graphics card from the PCI-E slot and then disassemble the shroud. Check to see if the fans are properly installed and haven't come loose. I've seen this in the past and the sound you are saying it is reproducing is usually due to a fan not being perfectly flush/level due to a screw that has come loose. Faulty manufacturing such as this is fairly common and doesn't usually occur until some time after it's been in use, thus slowly unscrewing itself over time, due to never truly being fastened into the assembly properly.
