Question i9 12900k temperature spikes

[Orbi]

Holla.. A week ago installed fresh build, with new z690 mobo and i9 12900k, til today everything was okay, temps were 60 in games.. But suddenly temperatures started to spike between 60-80.. Like.. one moment it is 60, then 65, then 72, then 63, then 70 and etc... Thought maybe it happens in one game, so tried another 2 games, same thing.. Any ideas? FPS are fine, no drops or something. Temps checked via MSI afterburner. No overclocked parts.

Corsair H150i Elite capellix.
EDIT: now noticed, that in game, temps stays at 70+, and jumps sometimes to 82 even. Even 70 are too high. Cooler failing? :/ IDLE always around 35. Usage in games 30-50%.

EDIT: tried reinstall windows - nothing. Tried reapply thermal paste - nothing. Actually noticed, that CPU usage also higher, spikes to 65%. Maybe CPU itself failing?
