P4DC6+: which temperatures on which sensors?

My P4DC6+ m/b has w83627hf health chip the supports 3 temperature sensors,
one for the motherboard and one for each CPU.

The output from lm_sensors (in Linux) is shown below. The m/b sensor is
apparently temp1. How can determine which CPU temperature is reflected by
temp2 and which by temp3?

Thanks.
