Sometimes I hear a strange crackle sound from my MacBook Pro 2019 16". You can check out the video that I've attached.
It happens when Mac wakes up, and sometimes at night when Mac is closed and I am not using it. The sound comes from the top left corner. Not from speakers, because the sound is mechanical. And not from a cooler, the cooler is to the right. Also, I don't hear it when I use Mac.
What could it be? As I know there is nothing mechanical in that corner. I worry about that. Thanks!
