What is a normal idle power for 3900X (redux)?

I mean "CPU Package Power" as seen in HWInfo, on a quiet Windows 10 desktop with overall CPU average usage at about 2% or less.

I'm seeing ~32W.  My BIOS has XMP and PBO enabled, and LLC = 8 (off); otherwise stock settings.

==> I just want to know what power value other 3900X owners are seeing, who are running at or close to stock.  No analysis or discussion needed... that's been done already.

It is hard to measure the CPU alone. My PSU can monitor overall power and my box with a video card at idle uses maybe 100W but when gaming it jumps up to 300W quickly.

AMD cool'n'quiet used to be able to lower CPU power a lot, but I am not sure if it is used anymore as opposed to different power savings ideas.
