Clock speed being funky after new cooler

[Sambadtech]

so the clock speeds where fine before i got my new AK400 digital but once i installed it the clock has been funny
in game cpu clock will stick to 3.6-3.7 ghz with 40-90% usage but when im not playing clock goes 3.7-3.9ghz with 1-30% usage
theres also this unnamed process thats taking some usage idk why

and yes temps are amazing after new cooler
never goes above mid 60s
