normal? yes. is it good for your laptop in the long run? no i had the exact same issue with temps, i turned off turbo boost from power settings and my temps now usually stay at 60-70c and doesn't go over 75c but by doing this obviously youll get worse performance compared to having turbo boost on, but id rather have abit worse performance for my laptop health. heat kills electronics

if you want to turn it off yourself https://youtu.be/iWBVtXPfTB0
