CPU temperature

[Links]

Hi,
A strange CPU behavior has appeared yesterday.
No matter, what I do, it rapidly heats up, and cools down.

In idle it's 30c and stable.
E.g I lauch browser - temp goes up to 50 or even more. (monitoring in aida64 and mobo onboard display), after the browser has loaded (1-2sec) the CPU goes back to 30c very fast. CPU fan rpm goes up and down, while the CPU temp jumps.

I click any link, open any document/programm (heavier than notepad or paint) and cpu temp jumps 30-55 and back.
In BIOS the fan is set to quiete mode.

CPU cooler attached well. (I think the temp wouldn't be 30 in idle if the cooler was loose).

Does anyone have any ideas?

I this case, it's not any overheating problems,
Those are definitly the heat spikes ( https://communities.intel.com/thread/110728 )

UPD:
1.25v and x48.
6 minute CPU stress test. 60-61c.
Everything seems to work.

Do i need to mess with that adaptive mode?

It's up to you, idle temps will be much lower if you use it.

Will there be any affect on performance?
Or the cpu will instantly return to it's high voltage/speed state if needed?

[Nate152]

Yeah, it will throttle at idle then when under load it will ramp up.

And in power settings I need to set the cpu minimal state to 5% (like in balanced) and maximum to 100%?

[Nate152]

You shouldn't have to fool with that unless you made changes in there.

In balanced profile those states are 5% for min.state and 100% for max.
In high performance - 100% and 100%.
Now i'm using high performance.

I'm talking about controll panel -> power options.

[Nate152]

Yes set the windows power plan to balanced for your cpu to throttle at idle.

Ok, thanx once again.
Do You use adaptive mode yourself?

[Nate152]

Sometimes. 🙂
