GA-6VXC7-4X sensors

Archived from groups: alt.comp.periphs.mainboard.gigabyte (More info?)

I installed Motherboard Monitor to keep an eye on my system temps and fans.
The closest supported MB available was for the GA-6VXC7-4X-P, so I can't be
sure the default setting are accurate.
There are three temperature sensors. The manual does not specify the
location/assignment of the sensors. Right now they read :
Via686A-1 23 Celsius
Via686A-2 28 Celsius
Via686A-3 34 Celius
I have been assuming the highest temp is the CPU, but I would like to know
for sure. What are the remaining two for? Thanks.
