Right now my CPU idles around 20-35 degrees and GPU is 35-40 degrees.

When gaming my GPU goes up to 65 degrees and my CPU goes up to 45 degrees so far.

What are good temps, normal temps and danger zone temps

 

[Demosthenest]

Those are good temps m8. Anything under 90 for the gpu and under 70 for the cpu is harmless for them. Your temps are very nice.

 

[Bossyfins]

Your temps are fine.

CPU : If it goes over 60ish/70, I would start worrying.
GPU : If it goes over 80ish/85, start worrying.
Dont let your GPU go over 90 degrees
