FIrstly if possible, try checking all the fans in the PC Case to make sure the airflow is adequate. Once that is ensured, try replacing the cpu cooler with another one if you can, that should help rule out any airflow suspicions. If the problem persists, try switching the cpu from that PC to some other PC if u have a compatible motherboard, that should help you know if the chip itself is faulty with sensors or not.
