I don't see the load jumping like the temperature:

No other ideas what could cause that? Maybe a specific bios setting?

That's to risky for me and I also don't want to loose the guarantee.

Oh wait, you mean the paste inside the CPU? (Sorry, newbie here.)

Hm ok, I used the paste which was already on the nzxt kraken x61. Thought that one is good enough.

hey, I have my i7-6700K stable overclocked to 4,6 GHz but sometimes the second CPU core jumps from 60-70°C to 80-90°C for few seconds. In the most cases it happens if I Alt+Tab out of a game. Why is it just the second core and all others are fine? Is this bad or can I ignore it if it is not more then few seconds on the temp? Any idea if there is a way to prevent this?
