Looking for ways to identify coil whine issues
Hello. I've started getting coil whine one year and a half after building my system and if I want to return anything I have half a year left. Coil whine's building up and it really annoys me, but is not directly connected to how fast my pc is running. While running cinebench, the coil whine didn't get worse. However while just watching videos or streaming, it'll pop up out of nowhere.
I took my pc apart and tried to pinpoint the sound, but it's very hard for my ears to pinpoint it. I thought it was the PSU but after taking it apart and waiting for the sound to pop up again, I think it's coming from the motherboard instead. On a gigabyte b650 aorus elite ax where would I push with a pencil with an eraser to try and see if the sound profile changes when it'll start making noise again?
This is the sound it makes when it drives me crazy.

Maybe I'll go borrow a stethoscope from a mechanic friend of mine over the weekend, so until then I'd appreciate some pictures with where I should focus my hearing on. Since I bought from amazon, they're pretty understanding with returns and usually offer refunds rather than RMA's, so I could order a replacement and return the culprit. But I want to be 100% sure if it's the PSU or the motherboard that's at fault.
I examined my PC and attempted to identify the noise, but it proved difficult for me to detect accurately.
Use an A4 sheet rolled into a cylinder and place one end near your ear while holding the other to listen for the sound's origin.
You mentioned the system was disassembled and breadboarded, without extra fans (except CPU cooling), which should help you find the coil whine. Pay attention to power delivery zones on the motherboard and GPU, as well as the PSU.
I noticed your specifications in the signature section. Please include the details of your build where the coil whine is present, as these can change over time and affect the relevance of this advice.
When listening to the audio, it sounds like a fan bearing grinding.
Also, remember to clean your components from dust after disassembly.
The components are sufficiently clean, any further cleaning won't make a difference.
I attempted to use the paper before I shared it, as it was the initial Google suggestion, but it doesn't assist in identifying the sound.
I'm unsure of the exact locations, which is why I posted and requested a visual guide on where to locate the sound.
The audio only contains two elements: a loud high-pitched coil whine and a pump noise from the AIO.
I'm only interested in the first one—the high-pitched coil whine—which is the primary concern.
