Enhancement: unify formating

[Flashwalker]

I suggest to make the color of the CPU temp the same as the other values (green in this case).

And add a degree symbol to the GPU temp value

Thanks for the feedback, I agree. The sections in green have warning/max levels and nominal levels. I think I wasn't able to find what a warning temperature for a CPU is in general, whereas that is given to me by the NVIDIA library.
