After water exposure, high fan speed

Water spill on my MB Air.

Replaced the logic board.

Batteries will not charge (a separate issue), so I start it up with the magsafe plug attached.

Boots like normal, but by the time it gets to the login page, the FAN IS RUNNING AT MAX.

The fan speed gradually increases over the first ~30sec after booting.

Any suggestions are greatly appreciated...

Did you replace the thermal paste when you reassembled it?

Good call Reed--that would've been a good explanation. But I DID use Arctic Silver when installing the new logic board.

Ok. Well, I hate to do this to you, but I have no idea. Sorry I could't help.

의 답변

Not sure if this was the solution or if I got lucky with the timing:

I went ahead and reset the System Management Controller

And everything booted up appropriately after that!

의 답변

Well, as a side thought, there may be a thermal sensor somewhere on the board that is shot.

Check both sides of the trackpad cable, the trackpad PCB and I/O cable for liquid damage and burnt pins. If any of these have issues or are not recognised it will cause the fan to spin high speed.

Try changing the fan speed in settings.
