Hey guys,
Replaced my logic board with the touch ID button as well which came with the board. Now my left fan is on full speed.
What I tried:
* Reset SMC
* Mac fan control (did not even change the sound or speed of the left fan, cranked up the right fan and I could hear it)
* Opened the whole thing again checking for connections and making sure they were plugged in correctly and properly, everything was perfect. (Visually checked to see if the right fan is spin which it does)
Any help would be much appreciated.
