Is that normal temps CPU etc?

GTX 1660 Super 72C

Ryzen 5 3600 with amd

idle 35-60C

in the game (240Fps) + Twitch

Cpu to 81C

GPU: up to 75C

Does that fit?

It's already warm in the attic

Yes it fits

Yes, that's perfectly fine. The fact that the CPU is so warm is due to the fact that the cooler doesn't have a lot of cooling power.

Is an amd wraith prism

Yes, as I said, it is not particularly efficient.
