Query: What component of the 360 S prevents overheating issues prevalent in prior versions?
Context: Two major hardware revisions of the Xbox 360 have succeeded the original models; the Xbox 360 S (also referred to as the "Slim") replaced the original "Elite" and "Arcade" models in 2010. The S model carries a smaller, streamlined appearance with an angular case, and utilizes a redesigned motherboard designed to alleviate the hardware and overheating issues experienced by prior models.
