High-pitched rattling / buzzing noise in the back of the console
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
