What cpu cooler are you using?i5 9400f -> i9 9900k
Didn't have this problem before but ever since I upgraded it freezes for like 8-15 seconds. I didn't make any changes other than my CPU upgrade.
What cpu cooler are you using?
Did you reuse Intel stock cooler for i5 on i9?
They have vastly different power consumption ratings.
i9 can consume over 200W alone (over 250W overclocked). Only liquid coolers or high end air coolers are able to cool it properly.
