I'm having a weird problem: when running stress test or when gaming my CPU would always fluctuate by 10c every 1-2 seconds I know it is normal when Idle because of changing frequency and all, but others report stable Temps fluctuating by max 2-5c
It passed each test (simple XTU stress test für 5-30m no serious aida or prime test needed as I don't intent to keep any OC as soon as I managed to get constant Temps)
No matter if @stock settings or @ freaking 5GHz ( always weird low temps no matter if in or decreasing Voltage)
- Idle temps at 28-33c
-Changed CPU Voltage (highest manual: 1.25v ; highest Auto: 1,3v)
-Turned on/off c-states and EIST

I only had screenshots for thos higher frequencys, but the graphs look like that on normal turbo-boost stock frequencys, too.
Look at the Green line to see the constant Temp changes.
Asus Z390-E
i7 8700k
seasonic 650w
gtx 1070
Kingston 16GB 3200MHz c16
Noctua 14s Cooler
Can anyone please help me?
If you need any additional Information or screenshots please let me know and I will provide them asap.
P.S.: Found only one thread with someone having the same problem only that his temps changed by 20 cinstead of 10c
Best regards
