is that your cpu temp? if so you might want to look into that...it could also be your northbridge chipset...or southbridge...or video card...i dont know what chipset temps are supposed to be...but thats fine for a video card.
usually in speedfan the cpu is temp #1 ( but not always) just run some extensive programs( or put ur had over the cpu fan) and see what temp goes up and that your CPU, im guessing that te,p is your graphics card
EDIT: ohh, i got a idea, go get everest and it tells the name of each temp rite beside it...
it doesnt refresh on its own? just click the refresh thing...by everest every thing looks ok..is the aux temp your graphics card? I have one temp in speed fan that goes below freezing somtimes..so that temp prolly doesnt matter...try to get another temp program and see what it says , like motherboard monitor
edit: my cpu temps are 32c idle and 38c load with stock cooling
