Hi. I noticed that my Xbox 360 S's cooling fan has been louder lately and has been making noises like it's not spinning correctly (like it's bumping something). I always have my games installed so it's really not all that bad. But yesterday I put in a game that wasn't installed, and the spinning of the disc started to slightly shake the Xbox more and then the fan (I believe it's the fan, but I'm not for sure) started making a noise like it was slightly hitting something. Now that I have my Xbox turned off, whenever I pick it up and set it back down, it really sounds like the fan or something makes some shaking noise right when I set it on the table. While I am not for sure this noise is the fan, I believe it is because that is the only thing I could imagine doing this. Lastly, the reason I ask if the Xbox 360 S has known problems with the fan is because my friend said his fan is also starting to make different, louder noises.
