This is what I get:
mbmon -A -d
Summary of Detection:
 * ISA monitor(s):
  ** Winbond Chip W83627HF/THF/THF-A found.
mbmon -I -r -c1
TEMP0 : 33.0
TEMP1 : 39.0
TEMP2 : 22.0
FAN0  : 1687
FAN1  : 1350
FAN2  :    0
VC0   :  +2.48
VC1   :  +3.65
V33   :  +3.26
V50P  :  +5.48
V12P  : +10.09
V12N  :  +1.05
V50N  :  +0.33

The meaning of the tags is explained in /usr/local/share/doc/mbmon/ReadMe

I'm not sure as to how reliable this info is. E.g. My negative voltages are
_way_ off and the +12V doesn't look too well, but the system runs OK. The CPU
temperature (TEMP1) is much lower than the on-die temperatures that coretemp
reports but that could just be because the sensor from the winbond chip is in
another place. 

And as I said earlier, chips like the Winbond only update their values once
every second. So you cannot use them to monitor fast changes.
