Asus Probe OTOH gets its reading from the die. It ought to show a temp lower than the others, pretty close at idle but 5C after being under load for some time. It can be much lower when core's first come under load.
One, or both, of the two is reporting incorrectly if TAT shows lower temps than AP. If Probe is right then TAT could be 10C too low, and I suspect is, based on your chip, the OC and the HSF. 46/47 under load would be extremely good with that setup.
