I use a bunch of Intel Core i9-9900K and Asus Z390-I Gaming motherboard. When I run some kind of stress test, my processor first runs at full power, gradually heating the Noctua NH-U9S cooler, but after 10 seconds it sharply resets the frequency for no reason.
When I run some kind of stress test, for the first 10 seconds (approximately) my processor runs at a maximum frequency of 4.5 to 5 GHz, gradually warming up. Then, for no reason at all, the temperature immediately drops to 65 degrees and keeps at 59 - 70 degrees, and the frequency does not rise more than 4.15 GHz.
What could be the reason?
