In my experience 'angry sounds' from a device, high-pitched whines and the like, are usually down to on-board switched-mode power supply components, often inductors.I don't think the PCB would make "angry sounds" but... a defective chip. Hmmm... Maybe?
If you push down on components in turn you might find which one is making the racket. Wear gloves to avoid any potential heat injuries.
