Does the software you are using, with the MAX6655 development board, allow you to log the values for the three voltage inputs simultaneously with the temperature?
I was thinking you could monitor Vcore with the Vin3 input of the MAX 6655, and connect a signal proportional to the current draw to Vin2.
You could then take the logged voltage and 'current' measurements, and multiply them together, and then multiply by a scaling factor to get the output power of the Vcore regulator. Accuracy wouldn't be great, because the voltage inputs to the MAX6655 aren't that accurate, but the ability to see how power consumption and temperature track would be cool.
Alternatively, I could design a circuit to just put out a voltage proportional to Watts. (I'm not sure how accurately I can do an analog multiply with a reasonably cheap circuit. I believe about 1% accuracy would be fairly easy to achieve. Better than that is probably reasonably easy with some calibration of the circuit.) This Watts output could then be connected to the MAX6655 and/or a voltmeter if greater accuracy was desired.
