It's not locked at a maximum, normally 125C, or a minimum, so it's not a short. The board is recent, so it's not an aged thermistor (recent boards use diodes). That your temperature being read changes, I've seen you post 114C and 117C, means it likely is not a faulty sensor. These chips, and those settings, can be altered freely at runtime (SpeedFan does this). Sensor chips also have offsets (which can be wrong), calibration curves (can be wrong) and a selection of whether their pin is reading a thermistor or a diode (can be wrong). Some sensor chips support dozens of sensors, a simply typo error in UEFI code can change sensor #07h to being sensor #17h. Thermistors age (faster when hot) while diodes can undergo an avalanche effect and lock at a particular reading. The diode or thermistor itself can be faulty. There are many ways a temperature sensor can give a silly number.
