PS4 squeaks very loud at power?

When I turn my PlayStation4 on, it squeaks very loudly. Can anyone help me?

So I would drive to a tech shop and ask if they know what is or what you can do

A drop of gun oil on the fan bearing?

Do you mean squeak with a short beep?

That would be normal and only a signal that the ps4 is turned on.

If not it will probably be on the drive or fan. Then you should like Leonie217 already wrote has a professional look over it.
