What BIOS version are you using? I'm running 13-current built from just a few days ago. Never had any temp sysctls since initial install (beginning of October).

Yeah, I don't have any sensors detected, but my BIOS reports around 39C, right around the same as yours. There are both motherboard and CPU temps in BIOS, reporting just a couple of degrees difference.
Overall, this system is very stable, haven't had any crashes or hangs.
