MBP Late 2013 A1502 High fan usage and kernel_task at 300%, mobo replaced no luck My computer is super laggy after my fiancee spilled water on it. I originally bought a new motherboard but still seeing the same behavior. Hardware diagnostics show PFM006 and PPN001. Anyone have any ideas? Thanks for looking.
I found a thermal sensor under the trackpad that was returning a bad temperature reading. This throttled the CPU and forced the fan to 100%. Bought a new palm rest/upper case assembly and will update if it resolves the issue.
