where on the motherboard is the thermal sensor for System Zone 1

[jaybrubin]

i am using Intel Active Monitor and System Zone 1 thermal sensor exceeds the 49c temp threshold which sets of the alarm...where on my mATX Intel D850EMD2 motherboard does the sensor reside...is it my way to hot ATi AIW9800?

do you guys agree with this assessment...?
