The problem isn't new but it's not solved in official images.

I found a solution for the problem in this forum (Thanks to Stephan).

It wasn't tricky, but if you want the short story:

  1. Download the changed kernel module
  2. Extract the archive and copy the amdtemp.ko file to your box, to /root
  3. Execute following commands:
    kldunload amdtemp
    cp /root/amdtemp.ko /boot/kernel/
    kldload /boot/kernel/amdtemp.ko

After this steps, you'll see the current temperature in the Dashboard view.
