i7 Temps Jumping around?

post #1 of 7
Thread Starter 
Has anyone ever seen that before? System was idle (after like 6 hours of Civ 5) and the temps were (seemingly randomly) jumping up and down 10-15C.

I restarted and checked the temps and whey were stable both in BIOS and in software.

Do you have EIST/Cx states enabled? They could be dropping your multiplier and adjusting voltage depending on load, would show as temp fluctuations.

What does Task Manager show Windows is doing when you get the temps jumping around?

How are you measuring? Try the latest Realtemp and do a sensor test. Try HW Monitor/Speedfan/Everest to see if they are all reading the same jumps.

How is your CPU fan speed set in BIOS, is it throttling down? Try a different fan header, one could be bad.

Worst case you have a bad thermistor.

Nothing in task manager. It showed up the same in everything. CPU fan is at a constant RPM.

There's this, too.



No clue at all.

EDIT: A quick search revealed Sin saying TMonitor can't be trusted, so ignore that.

As an addendum, I should clarify that I don't actually think the temps were jumping around, rather that the sensor was spazzing out for whatever reason. I'm guessing there's no need to worry, right?
