Sound coming from the CPU area at the back of the motherboard in my new computer
Hi, this is Omar.
I recently purchased a new computer about a month after receiving it. At first, I noticed a strange noise coming from the motherboard. The seller was very helpful and replaced my RTX 4070 12GB with an RTX 4070 Ti Super. After that, the issue persisted. They then upgraded my motherboard from the Asus B760 to the Asus Z790 Plus and changed my power supply to the Asus Gold model. Despite these changes, the problem continues.
I have conducted various tests and the computer now runs smoothly without any sound during gameplay. The audio only appears when the screen goes black or when entering the menu. I’ve checked all hardware and software settings in BIOS, adjusted the CPU settings, but nothing resolved the issue. I’ve also changed the CPU to an Intel Core i5 14600K, yet the problem remains unchanged. It isn’t coil whine; it’s a consistent sound every time I replace a component.
The noise originates from the back of the motherboard, specifically the metal part with a grey finish. I also verified all fans were functioning properly, and at high speeds they didn’t produce any noise. This is quite puzzling.
Could you please assist me in resolving this issue?

Well, you haven't explored all possibilities yet, as there are still tasks left to complete. It might be related to MoBo coil whine; if that's the case, replacing the component is the only solution. For more effective troubleshooting, remove the MoBo from the PC case and place it inside a cardboard box to see if the strange noise persists. This method is known as breadboarding. Another approach is to boost white noise levels, which can mask other sounds, or use a better soundproof headset so you don't pick up that noise.
