Hello, I have the same problem with my T17. I contacted the Zeusminig authorized service in my country and the technician confirmed that this problem is very recurrent in T17 and T17+ models. Mostly it is because at some point the machine was exposed to high temperatures, damaging the temperature sensor, the good news is that they have already repaired this fault by replacing the sensor, the bad news is repair cost is $80 for each board. If I have any new news I share it.
