Hi there, can someone explain me what these below options on BIOS exactly do?

Global C-state Control
Power Supply Idle Control
CPPC
CPPC Preferred Cores
PPC Adjustment
PBO

I'm using ryzen 3100 and I want to my system stable as possible and reduce the temperature but I don't want to break anything. I think all of my cpu cores are active on idle by default. My idle temp is bit high. Many people suggested to tweak above settings. My chipset drivers and bios are already updated and using Ryzen balanced power plan. Can someone explain me what those options are and should I set those on or off?

Thanks in advance.

By high, what sort of temps are you seeing? You might want to mention your cases airflow and your ambient room air temps. Make and model of your motherboard? Lastly, make sure you're on the latest BIOS update for your motherboard then take note of what options are enabled by default.

Any overclocks(on the CPU/ram)?
