thanks for sharing the information you received, I don't have much knowledge of electronics and unfortunately I must trust what they tell me 
It really makes a lot of sense what you say in reference to the 4 temperature sensors, how probable it is that all 4 will be damaged at once?
but is it also possible that if one fails it will send incorrect information to the other 3? I don't know, as I mentioned before I have no technical knowledge of electronics and I don't know if this is possible.
In my case the 4 sensors of the 3 hashboards are failing, so I read this failure is related to the PSU?
Something that also disconcerts me is that my T17 in the cooler hours of the day works normally.
Which is why I thought it made sense that the temperature sensor.
you say you solved the problem by pressing on chip 1
Did your t17 fail on just one sensor or all of them like mine?
