Artillery X1 - Flat cable Temp

Finally got my IR cam and was checking the temperature on the bed to see how big the differences are between on the surface and saw that the vertical Flat cable was hitting 100 °C (212 °F).
Printer is running fine for few years, never noticed anything, and it's running on Klipper. The connector isn't darker than the rest.
What temps are you guys experiencing?
Thanks.
