It is possible that the 3rd temperature is invalid, thus please send or attach a HWiNFO32 Report File with sensor data, so I can check more precisely.
Also please check in BIOS or via Gigabyte Easy Tune (or similar tool) what temperatures it displays.
In the Gigabyte Easy Tune 6 is only the CPU Temp and the System Temp. Its not a 3. Temp.
The Log and Debug File is the same as here:

Thanks for all the data.
The "Temperature 3" is most probably an invalid reading that I'll remove from reporting. I'll also adjust the other temperature, voltage and fan readings to report correct labels and values for this mainboard. It will be available in the next Beta release.
