Laptop or not, I certainly wouldn't be comfortable with CPU temps in the mid 90's C either. Even though he may not be at his thermal limit, he's getting awfully close to it, and running that close to it for a significant period of time certainly isn't what I'd call healthy for the processor.
I'd google the laptop model and CPU model and see what temperatures other people are reporting. If nothing else, get a cooling pad for when you are gaming! When you're only a couple degrees from your thermal ceeling, even a difference of 2 or 3 degrees could have a large impact on your CPU's lifespan.
If you do this you'll find that it corroborates what I said.
