I installed an Aerogate II fan controller in my rig and for the time being I have the cpu sensor Scotch Taped to the side of the HSF. It reads 38.5 celcius but my software monitor for my Asus P4P800 mobo reads 30 celcius. Which of these is accurrate? I would think if anything the outside of the HSF would be cooler then the chip. THanks
