So i don´t know if its normal, but when Im playing some game, not even a big one, my laptop gets really hot from the front, my GPU temperature goes around 47 ° C, but the CPU goes up to 95° C, and the moment I stop playing it goes down really fast like to 80° and then like around 60°, to see the temperatures I use OMEN GAMING HUB, my laptop is Omen 15 dc0003 la 2018.
I always have it raised to allow air to pass underneath
