Windows 10 is causing my CPU and GPU to overheat.
GPU temperatures are high at 83, but CPU temps are normal, ranging up to 77 during rendering and 72 while gaming.
I believe it's fine. Could you tell me the specifications of your CPU and the cooler you've added?
I7 4790k paired with Phanteks CPU cooler
It wouldn't be wise to aim for 85; anything lower is acceptable.
Sure, happy to help!
