weird noise from my xbox 360, anyone else experiencing the same problem?

So when I turned on my Xbox360 today it was making this weird noise, besides the normal noise of the dvd drive that is usually makes when I turn it on. (I have no disc inserted) http://dontknow.me/at/?http://rapidshare.com/files/166913478/Sprachmemo002.amr.MP3
Bought my Xbox in May 2008 anyone else have this problem? Sorry for the bad quality of the mp3

My xbox 360 got increasingly louder as it approached its untimely rrod. This may be a bad sign for you.
