I recently built a PC and noticed that the motherboard has VRM coil whine, which is especially bothersome when I'm gaming at night. My specs include a 7800x3d CPU, a Gigabyte B650m Aorus Elite AX Rev 1.0 motherboard, 32GB DDR5 Klev Bolt 6000 MHz CL30 RAM, a PowerColor Hellhound 7800XT GPU, and a Corsair RM850x 850W PSU, all housed in an ASUS AP201 case. I'm seeking advice on how to minimize this coil whine. Here are my specific questions:
1. Are there any BIOS settings I can tweak to reduce coil whine when the CPU is under heavy load, like when I'm hitting 165 FPS in Battlefield 6?
2. Would switching to a different case with solid back panels help cut down on noise?
3. Should I consider purchasing a different motherboard, even though I got this one used and switching might lead to a loss?

You could try lowering the CPU's power draw. Another option is to test with a different power supply, as that sometimes helps. Lastly, changing the motherboard is possible; even getting the same model might yield a different coil whine experience since every board can vary a bit.
Have you thought about undervolting the CPU? I can't provide exact settings, but it's a strategy some people use to help reduce coil whine. Just remember that shopping for parts with coil whine can be hit or miss, so make sure you can return anything you buy if it doesn't solve the problem.
