Hello, so Air have oc my i5 9600k to 5ghz and 1.350 v running at a stable GHz in all cores but when I start stress testing it skyrockets to 78c and peaks at 82 c. After 1 minute it cools down to the mid 60s and after 2 minutes it skyrockets again. Is it bad and can I lower the voltage a bit to get better temps. Mobo I'm using is msi z390 gaming x
