You have 4 cores on your cpu. Usually, one or two readings are higher as the unused cores run slightly cooler. Check your readings against the bios by quickly using the reset button and entering the hardware monitor section of the bios. Those readings, if accurate, are normal. I set my shutdown temp at 70c in the bios for safety.
So my 2 core can act as a 4 core? I'm a bit confused O_o
