Which temps are 37-69'c? CPU, or GPU? Or both? In Superposition, I'm assuming the GPU.
It's going to depend on the cooling solution (and airflow). The lower the temps, the better to achieve higher boost clocks etc. But 80'C is pretty typical for the 2080TI from what I've seen, and the max 'safe' temp as per Nvidia is 89'C
