Having thought about this for a minute, I will admit that the diode could
be referenced as a sensor of sorts, but it by no means actually gives any
temps, just voltages that are read by the actual sensor chips that are on
the MB. So, I recant, hoping everyone realizes that it's still just a part
of the sensor circuit and is absolutely worthless without a sensor chip on
the MB. Which I think was what the original poster was wanting to know.
Both cpu's have the same diode as the are the same core.
