I didn’t know that!Keep in mind the 2700X is 15°C lower in temps than displayed. AMD use this temp offset to have the fans more aggressive to reach higher clocks if the temps are good. The default 2700 has a higher temp limit and no offset. So in you usecase if you would have a 2700 none X and clock it to the same clock the temps would be 15°C lower without throttle
But about the temp, are you sure? I am pretty sure that the wrong reading temp has a delta of only 5 degrees and not 15...
