"According to del Castillo, the Xbox One will be self-aware of its temperature. As it starts to heat up, the fan will kick into high gear to attempt to cool it down. If that doesn't work, the device will cycle down its power usage to cool itself off. Of course, that will reduce the Xbox One's performance, but it also will reduce chances of needing to replace the hardware."
