NF7-S v2.0 CPU Temp reading for Barton, where?

[ZoSo]

I just bought an NF7-S v2.0 for one of my machines and was wondering where the temp reading will come from using an AthlonXP 2400+ (Barton core).

Will it come from the sensor in the CPU well in motherboard or from the chip?
When using MBM I guess I can get the temp reading from the chip itself?

Thanks,
