Hi niedzial1983!
Not absolutely sure for precisely your model, but for it's 15-inch version, GL553VD, according to Asus tech support, upper limit for safe temperatures is 85C for CPU and 90C for GPU. According to third party sources (such as
tom's hardware guide or smth
else), it's better if temps for both GPU and CPU should not exceed 80C.
By the way, could you tell me, what are you ambient temperatures? Not just after power on, but for 15-20 minutes on idle?
P.S.: for such images there is a pretty button above NumPad's "*" called PrntSc
🙂Use it, than paste in any graphic editor.
