I realised tat when i game without turnin on the air-con, my com tends to like to restart itself after around 30mins of assassin's creed/gears of war. when i turn on the air-con,it can last for hours. So is it a heat issue?My CPU temp is normally around 55-60degC when gamin and GPU 65-70degC. Is that considered sooo hot that the pc have to restart itself so as to protect my cpmputer components?
