820-3126 fan accelerated

[iClub]

Good afternoon I made the repair in the USB ports, where the controllers and inductors were damaged, the tests worked the ports, but the fan is accelerated, I wonder what sensor is causing this?
fan gives CPU speeding.

Run corresponding EFI ASD and see if any error pops up.
HWMonitor can also show some intersting information about temp sensors.
Trackpad flex/board can cause such an issue.
Try disconnecting webcam flex too.
