As for your GPU, this depends on what resolution you are playing, as 4k will generator more heat than 1080p,
Uncapped frames will also generate more heat. I have a 60hz monitor, and a 6900XT and it rarely goes above 75C at 4k when I turn on the vsync or cap it at 60fps in game.
As for the processor, it could be getting that hot because the GPU is right under it, and could be sucking in some of the heat off the GPU. And that again also depends on the games which are more CPU demanding.
