I'm new to overclocking, and managed to set my manual voltage down to 1.175v on my i7 8700k @4.8GHz. But i want it to change dynamically so it adjusts down when the CPU is not using any load. I have tried setting it to offset mode, then it stays on my preferred max voltage, but doesn't go down when idling. Also i have to force my CPU to go down in clock speed/idle, it stays on 4.7GHz constantly, with only a split second in 800MHz and then right back up. And if i force down my CPU clock the
voltage doesn't change
. What am i doing wrong here?
I have enabled C States in the BIOS
.
I am using a Maximux X Hero with the latest BIOS (0505).
Here's an album with all my settings

I've attempted that before, but it still operates at the same level, only differing in that it now defaults to 1.2v and I'm unable to modify the settings further regardless of the adjustments made for the "Additional turbo mode CPU core voltage."

Activated extra turbo mode, keep offset unchanged.
Reminder: You can't adjust the adaptive voltage below the standard level for a specific CPU ratio.

I configured it in this manner now:

It continues to function only as a fixed 1.2V setting:

You won't be able to lower the adaptive voltage below the standard level for a specific CPU ratio. It might not work at such low voltages—consider increasing it and testing.

Even adjusting it to 1.4V has no impact...

The goal is to lower the voltage so I can achieve a cooler temperature on my desktop, which is currently around 40-50°C while idling. Is this something you should be concerned about?

The reason I need the voltage reduced is because I want a lower temperature when I'm sitting at my desk, it's running at 40-50C, is this really something I should be concerned about?
That's unusual.
Which cooler are you using?
What are the load temperatures?

I'm working with an H80i V2 and setting load temperatures using Prime95.
