The mapping of the temps is controlled by the motherboard design and the 
BIOS.  On most Intel motherboards...

temp1 = PECI CPU temp.  I.E.  Degrees below thermal throttling.  Similar 
to what coretemp reports.
temp2 = aSC7621 chip itself.  I.E.  Motherboard temp.
temp3 = Sensor between the DIMM sockets.
temp4 = CPU diode temp.
temp5 = temp1
temp6, 7, 8 = Documented by Andigilog as additional PECI temps but not 
documented by Intel.

That's all the info I have.
