I recently bought a i5-9600kf cpu and I've been doing some overclocking. I've got my CPU running at 5GHz stable during benchmarks and in games. When stress testing my CPU in cinebench my CPU temps are usually in the mid 80 although I've seen it spike up right to 90c. Is this CPU running too hot? What would a safe temp range be? BTW, it scored a little over 3,000 in cinebench.
