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 SMCMac 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.
Likely the ribbon cable connection to the case needs to be checked, use a magnifier to inspect the ribbon contacts are not damaged. Also make sure to carefully lift the clamp bar to release the tension on the ribbon and make sure to fold it back down to set the clamp bar down when you’ve put the ribbon cable back in. Here’s a picture with the clamp in the up position.
