AMD 7840 Fan and Temp issue (negative temp, fan is not starting)

[George_T]

Found the solution for my case.

Temp sensors on Framework 13 7040 series report negative temps

This kinda sounds weird, but I found a solution for my negative temp sensors in not a so obvious way. Long story short – I tried to replace EVERYTHYNG screw-by screw, and sensors fixed after replacement of … O_o … web-camera cable. Cable produced by EST (from the new cnc cover) - negative temp sensors. Cable produced by DX (from the original cover) - good state sensors.
