CPU temperature jumps

Featured Replies

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?

It can be bad contact the tim under ihs, you need to delid it and change with much better paste like Thermal Grizzly Kryonaut or Gelid GC Extreme.

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

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

Yes, inside the CPU.

 

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

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

There might be a specific type of operation that causes heavy load on that specific core, hence the temperature.
