I just heard a really weird and troubling noise when I manually (use the button on the console) shut down the Xbox. The best way I can describe it is it sounded like little bits of metal hitting a fan. This console has only been out for two days now and hearing this made me really unsure of how long it'll last if this keeps up. I've tried to replicate it multiple times but it has only happened once. I'm wondering if anyone else has had this problem yet and if there is something I should do.
