looking good
I have bad experience with socket termistors. I have had board that measures 10C wrong without airflow near the socket as best and as worst was the 8RDA+ with airflow around the socket. I got the 8rda+ to read 25-30C to low =) Even under watertemp with an unclocked cpu. Due to the airflow cooling the socket sensor..
but anyway u did measure with an external with probely is a little better =)
BTW Keep up the good work
