i5 7600k with idle underclocking.
I adjusted the settings to keep the processor at a steady 4.7ghz and checked the impact. The cooler used was the pure rock slim. When idle, it reduced speed to about 1.06ghz. I asked what setting I should change for consistency and whether performance would differ.
Intel offers a feature that reduces voltage and heat when the CPU is idle or under light load, extending your PC's lifespan while saving energy. This process is standard and poses no issues for your system. See wiki

Keep the settings unchanged. If the clock reaches set overclock during heavy use, problems shouldn't arise. If concerns persist, disable the 'core C6 state' in your BIOS. This lets the CPU adjust its voltage and can shut down entirely.
Change the CPU ratio mode from 'Dynamic' to 'Fixed' in your BIOS configuration. In dynamic mode it will automatically reduce the ratio to save power. With an MSI z270 krait board, your settings might have slightly different names. Also, if it isn't set to change automatically, disable 'Intel turbo boost'. Since your clocking exceeds the standard 4.2ghz, it's not necessary. I'm running a 7600k @ (fixed) 4.2ghz using a Corsair H75 and my average idle temperatures are around 40°C. With your cooler, those temps should rise slightly. I've noticed from several online sources that gaming performance drops when dynamic ratio is on, though I can't say how much. Edit: It turns out my H75 pump was almost out of stock, replaced under warranty. I sold it and got a H80i v2, now idle temps are between 25°C and 28°C.
