My ps4 pro started making a high-pitched rattling sound (comes from the back where the cables / power supply (?) are). It doesn’t do that when I start the console, but while I play a game and takes a while to stop. It also seems to be worse with some games and better/ non-existent with others. I opened it to look at the fan but saw nothing, it’s not even dusty. Also, fan is located at the front of the console. What could it be? /edited the question to better describe the noise https://photos.app.goo.gl/babiuVQbQU37ck… <- link to the video

The question doesn’t describe the sound well, however if I guessed correctly, google “inductor whine” and check if it is the same sound. If it is, this is normal.

My PS4 slim started making this noise shortly after putting a new power supply in it. The sound would also continue for a short period of time once I turned off the PlayStation. It worked for about 2 months with the sound then it just turned off and doesn’t turn back on , but when plugged in I can still hear the sound and when I try push the on button it changes pitch. It also still makes the sound for a short period of time after unplugging it. I want to think it’s the power supply but it’s brand new ,original one in it and the hardrive is still the same from when it was bought in 2016 so might be the hardrive.
