Alienware Aurora, high pitch noise after command centre update (March 31st,2012)

​Hey guys,​

​So recently I updated the command centre on the alienware aurora to its latest (I believe it was 2.7.25.0), and am now getting a relatively high pitch noise emanating near the top-middle portion of the tower. I've done a few fan tests, playing with different levels of fan speeds from the thermal controls and haven't had a change in pitch to narrow down the problem. Any suggestions for fixing this problem? . Thanks in advance.​
