I've found AMD document for this generation of CPUs and compared it to FreeBSD and Linux temperature monitoring drivers, and I found nothing wrong or missing in FreeBSD driver.  So without this being a wider problem and without ability to reproduce it locally I am going to close this ticket.  It may be a weirdness of specific motherboard.  But you may try to report it to upstream FreeBSD in case developer there who more often works on that driver get any better idea.

I installed the kernel but all temps is the same as before.

I uploaded a new debug.

Alexander Motin March 4, 2021 at 3:23 PM

I've merged some AMD temperature monitoring changes from FreeBSD head into upcoming 12.0-U3.  If you can, please help with testing changes by installing the attached kernel:
 - update to 12.0-U2.1;
 - create new boot environment just in case;
 - upload the archive somewhere on the NAS;
 - in command line run:
   cd /boot
   rm -r kernel
   tar -xzvf /path/to/the/kernel.tgz
   reboot

And tell us what you get.
