Here's what I've figured out about monitoring on this board...
BIOS, Speedfan, and SmartGaurdian all pull monitoring values from the ITE SuperIO Chip the IT8712F which includes voltages and a few temps (CPU, NB, and SB).
Note for those who don't already know... the temp in BIOS called "PWM Area" is mislabled... this is actually the NB temp.
Like many others have said, the CPU temp pulled from the IO chip should not be trusted... CoreTemp rules. Both Everest and Speedfan also pull the same data from the same registers as CoreTemp so you can use Speedfan or Everest to do the same thing. With Speedfan, you simply need to add a 15-deg C offset to the reported values to make them match with Coretemp (it's built-in offset is not correct but the values from the registers are).
Speedfan can see Vcore, the HT Voltage, and the NB Voltage but initially displays them as Vcore1, Vcore2, and 3.3V... simply rename them with the proper labels.
Unfortunatly Speedfan current doesn't seem to report the VDimm or SB Voltage, but not a big deal. It also can't control the fans which is a shame... you need SmartGaurdian for that (why is it so damn ugly!).
Hopefully a future version of Speedfan will offer more comprehensive monitoring of this board. I'm logging an issue with the author now.
That's about it for monitoring on this board that I know of.
