recently my xbox 360 fans have been getting stuck in on mode. after playing the game and turning off my xbox 360 the fans stay running. after about 2 hours, the fan is still running. i turn on my system and turn it off quickly and the fans finally stops. almost like a temp sensor is not working or something. the fans dont seem to turn off on thier own anymore. any advice? is my xbox 360 dying? dont tell me to buy a ps 3 i have 60ish xbox 360 games.
