i picked up a XBox 360 E 250gb console back in Nov. 2013. i usually play about 3-4 hours a day and everything has been great up till las'night. a few minutes after turning on my machine it started making this loud humming noise. at first i thought it might of been the driver, but it's the fan. sounds like it's getting over worked or something maybe. it still does it even with no disc in the drive and is there from start up to shut down so this is why i'm thinking it's the fan. as far as i can see the machine is clean (not even any dust build up around the vents) i was wondering if this is a problem with the newer "E" version or do you think it's a one off problem only affecting my machine? the machine is working fine from what i can tell, just the loud fan noise bugs me and i have to turn my volume up to hear over it.
