I have a p8z77 v-pro a 3770k and a coolmaster 212 evo. I am concerned that my sensor on my motherboard is reading my cpu temperature wrong and failing to increase fan speed. My suspicion arises from the fact that I can be playing a demanding game i.e. planetside 2 for 4 hours and my cpu temperature never goes over 45 degree c. I have yet to overclock at all. Do these temperatures seem normal or are they too low.
