Hi all.
I have3 a mid-2018 MBP A1989 (EMC3214), that makes a popping/crackling sound when the unit gets hot.
I've removed the base cover and cleaned the fans - which were already spotless, and seem to spin fine with zero resistance.
I thought that the microphone may have been picking up some sort of electromagnetic interference from the right hand fan, however I've muted the microphone, and also muted the speakers, and I can still hear the sound.
I also disconnected the speakers, with no change.
I also reset the PRAM/SMC.
I tried installing SSDFanControl, but it doesn't correctly detect the fans on this model.
The noise seems to come from the right hand side to the machine, and if I manually stop the fan, the noise ceases immediately.
So it should be the fan, however I've never heard one that sounds like this one does!
I've attached a recording of the sound, in case it helps.
I'm assuming replacing the fan should fix it, but, any other suggestions or known issues anyone can think of?
Thanks for reading.
