Yes! It's supposed to! Because the motherboard is a process holder and the electrons going through the motherboard at the speed of light to process the info at seconds and milliseconds at a time. Same goes for your ur monitor, smartphone and tablet. Except the PS4 has a fan because it's more of a powerful "machine" or device, that can move or process more info quicker. Just like ur iPad, Samsung, Amazon Fire or iPhones or Samsung phones. Everything overheats. Just like when you get a headache for processing more info, it hurts to stop ur brain to stop and rest. My PS4 and iPhone and Amazon Fire HD 8 8th gen gets hot playing GTA all the time, or browsing the web.
