I have legion y540 with i5 9300h and a gtx 1650 . I'm currently using throttlestop to undervolt the cpu by -150 mv and to limit the tdp to 33 watts . Even after this cpu spikes to 90-92° celsius for just a sec but the average temps are in 70-80° celsius range . I game a lot , my session lasts more than 6 hrs . I'm just anxious bout the longevity of my laptop . Tell me if something is wrong and what do i need to do if so .
