On the lower/right half of the console (depending on how you look at it, it's the part with the power button), today it has an odd rumble-like noise. It sounds sort of like the fan is blowing too fast, or something around the fan is slightly out of alignment, causing it to do a rumbling sound.
This happens whether there's a disc in or not, and starts within 10 seconds of turning it on. Just started today, although I remember it happening once before, several months ago, and I forget what I did (if anything) to stop it.
It's almost certainly the fan, but does anyone have any ideas for what to do?
EDIT: Ok, it went away after leaving the 360 sitting on the dashboard for a few minutes. I'm guessing something was slightly ajar with the fan or something and it (probably) corrected itself. Still would like a more concrete answer if anyone else has had this issue before.
Eclipsing power is, at times, not only the instrument of demons, but also of gods. Lost, but not forgotten.
my system makes a rumbling noise if I go to dashboard with a game in the system, but don't play the game. Once I start the game, it goes away. It also has a constant pulsating noise from the fans (Like they spin up and slow down constantly)
