Yes, it's generally fine for your i5 6600K to maintain a constant 1.26V core voltage.

i increased my i5 6600k to 4.4ghz with a 1.26vcore and tried adjusting everything to lower the voltage during idle. despite those efforts, the voltage remains between 1.2 and 1.26v even when it downclocks to 900mhz. the cstates setting on my gigabyte z170 also doesn’t seem to help. i’m wondering if this sustained high vcore really impacts the lifespan of the cpu or if it’s just a minor concern. thanks in advance.
Not much to say. Long ago, CPUs operated at full speed with steady voltage, and techniques like SpeedStep were created to boost efficiency. It's safe to keep the CPU at a fixed voltage within normal limits. Below 1.4V works well for regular use. Power savings from voltage reduction are turned off when the core is managed manually. Auto mode lets voltage adjust automatically with frequency changes. C-states switch SpeedStep, which adjusts speed according to workload.
