So it's probably either a sensor which doesn't actually exist, one not calibrated right or one which shouldn't be exposed. 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). Once it finishes just double-click on the Speccy icon to check CPU temps. Some sensor chips support dozens of sensors, a simply typo error in UEFI code can change sensor #07h to being sensor #17h. I for example press Del for a few seconds until the case speaker starts making a noise. Thermistors age (faster when hot) while diodes can undergo an avalanche effect and lock at a particular reading. Re: CPU Over temperature error To get to your BIOS, restart your computer, and look for the function keys at the bottom of the screen just as your computer starts up (within the first few seconds). Print out a copy of your system information by clicking on the File menu > Print.

Speccy also lets you have a printed report of your system information. Click on File menu > Save as XML or Save as Text file. The diode or thermistor itself can be faulty. Saving reports as a Text file and XML file follow the same process, as shown below. There are many ways a temperature sensor can give a silly number.
