Hi guys! I'm running Gigabyte Z370N with i7 8700 and Noctua NH-L9i. If I'm not mistaken, this motherboard has the ability to change VCore voltage for my CPU. But I can't see any improvements in temperatures after undervolting.

In Gigabyte Z370N stock VCore temperature set to Auto. I use this setting and ran Prime95 26.6, Small FFTs.





Then I played with VCore voltage and found out that 1.140 volts are stable for me. I ran the same test, but the temperature was even higher.



In both cases, HVMonitor shows similar CPU voltage.
Am I missing something?
