speedfan query

hi,
please check my rig. i have installed Vista ultimate with all applicable patches.
then i have installed speedfan on it. it shows 43 as proc temp but Aux temp is 119. do you think there is some problem in application.
what is Aux temp for?
and what it should be default.

This might help

Computing.Net - my aux temperature shows over 120C

BTW whats the graphics card temp?
