mystery temp in everest...aux?

see pic :P
what would everest be reporting on for the aux reading?
i was thinking either gfx or north bridge
i have a radeon 9200, dont know if they report temps or not
but it has a little monitor for the icon :unsure: :P
and the last time i touched my north bridge heatsink...
it felt hotter then 36 C :lol:

Perhaps the case temp.

buy 10 more fans fkdup :P

my PC runs at 45c 24/7 im nto paranoid

Auxilary is referrring to a built in sensor in line with teh CPU...(CPU2)
It will get some astronomic temperatures ie:60degrees +
Most motherboards report it as what it is
