Server power consumption issue (powerd, speedstep, Intel Xeon)

Hey guys :)

I am having issues with the power consumption of my server. Its higher than normal (30-35 watts higher) and the fans are spinning at mid speed (when idling and with a CPU Load between 0.0% and 0.8%). I never had these problems with 11.2-RELEASE.

OS: FreeBSD 12.0-STABLE[/I]
CPU: [2x] Intel Xeon X5650 @ 2.67GHz (2x6 Cores == 12 Cores/24Threads)
Server: HP ProLiant DL380 G7
Speedstep: Should be enabled (I can't find the option to enable/disable speedstep)
powerd: enabled

The are no PCI cards in the server... I am mentioning this because the HP Firmware is programmed to speed up the fans if a PCI card is installed but in my case it isn't.

Output of dmesg | grep Speedstep:

24 times
est: CPU supports Enhanced Speedstep, but is not recognized.

Thanks in advance :)

This could be an indication that the “BIOS” power management is configured in a way powerd doesn’t recognise it properly. Have you checked in the servers RBSU, the “Power Management Options” -> HP Power Profile or -> HP Power Regulator?

Edit: With 12-STABLE you are running a development branch in which all functions to run as expected are not guaranteed. You could try booting a 12.0-RELEASE image and activate powerd afterwards.
