Also what should be the hottest my CPU gets fully loaded running prime95?

I just reworded the whole post if anyone could answer my questions that would be a great help.

My goal is to have my CPU overclocked to 3800mhz, my ram to 1600mhz (or as close to it as possible). I just do not want it to overheart or any other issues

How hot does it get running games or prime95? Mine gets around 67% at peeks after running prime95 for a while.

The cpu fan I have is.
