Question CPU wont drop below 3ghz when idle

[Mindrust]

Hello, I have a 10900k CPU on an Asus z490-f motherboard. I have c states enabled in bios, along with intel SpeedStep and shift speed.

inside windows, I have the power plan to balanced with the minimum processor state at 4% and the max at 100%

My CPU does not want to drop much lower than 3ghz when idle, (2% utilisation on the CPU) I would expect lower comparing with my 6700k which can drop to 800mhz.

is there something I'm missing here?

does it have mce multi core enhancement in the bios? might need to turn that off

Hi rgd1101, just disabled that to see if anything would change.
And it seems to be the same.

hw monitor seems to be telling me different things compared with the windows task manager.
My CPU cores are not synced.

Thoughts?

I've tired all the plans. Neither of them seem to make any difference. Perhaps a clean install may do the trick I wonder.

ok task manger. yeah. don't use task manger

Acutally turns out the problem stems from having corsair ICUE running. shame because I use it to manage keyboard, mouse, AIO and fan controller. So.. no wonder it uses a bit of the cpu to output all those instructions
