Coil Whine or completely different difficulty?

I cleaned, checked with a brand new fan, modified the PSU fully and switched energy cable. It's additionally not the audio system subsequent to it.

However one way or the other my Xbox has some highpitched noise coming from it once I'm ingame. That is and not using a disc (which I do know makes some noise (I'm fantastic with that)).

Flip up quantity, trigger my cellphone doesn't actually catch it on the low-end.

It's seems like a high-pitched squeak (like these low-cost chargers you’ll be able to hear if you cost your cellphone with them). Like that.
