Like I said though. The sensors are going to be variably inaccurate, so you might as well, just go by what the sensors say and take it with a grain of salt. If your temps get too high, then your overclock will destabilize, and you'll lower your overclock, which lowers your temps, and then it's stable again. Trust me, I have never put a thermometer next to my core and tried to tell the difference. A good person to PM would be @mdocer though. He knows a lot about temp variance on NF7's and the like.
