the temp sensor for the MB i think is the NB and the aux is the pwm or its the other way around. i dont really care about the core temps but they were just zeroed and it seamed weird.

also with the gd70 u need active cooling on the NB i put the 40mm from the blackops on the NB (just screw it in the fins will lock it down) and it dropped the motherboard temp by 20c and the aux by 15c
