My overclocked system is crashing when a certain temperature, reported as TMPIN5 in OCCT goes beyond about 53 degrees C.

I would like to know exactly what the TMPIN5 sensor measures on the Fatal1ty X299 Professional Gaming i9 XE motherboard.

The temperature at this sensor rises gradually when I run a burn-in test and when it hits >50 C, the system becomes unstable using the overclock settings I am using (at around 4.8 GHz, 1.8 Vin, 1.625 VCore x 18 (i9-7980XE cpu), AVX512 instructions on, Prime95 Small FFT).

If could not find any documentation about the temperature sensors on the Fatal1ty X299 Professional Gaming i9 XE motherboard and where they are located. I am particularly interested in TMPIN5, since this seems to greatly affect my ability to overclock at the moment.
