As far as I can tell, there are only two temperature sensors accessible 
via the BIOS, CPU and MB.  I'm not sure of the location of the MB sensor 
is located but it doesn't seem to correspond directly to the chipset health.

I've used mbmon + cacti to keep an RRD history of the temperature and 
fan speeds.
