Hey Brink, any idea why Windows wouldn't be obeying the minimum limit I set? I have restarted the machine and it's still idling around 5% (where the chirping noises start).
If there's a BIOS/UEFI setting for this, it could override.

You can also check in Task Manager > Performance > CPU > Open Resource Monitor to see what is currently using the CPU.
