Unable to detect PC sound issues (links included in video).
Initially I assumed it was a GPU fan or front fan hitting a cable, but it doesn’t seem to be coming from there. It’s not the hard drive (which is in the front if the case is at the bottom), and it appears to originate from the back. Could it be a faulty CPU cooler? What does it sound like?
you might be hearing issues due to vibrations from one component, like a hard drive, causing another part to shake (for example, a fan filter). to check if it's a fan, gently stop each fan one by one by placing your finger on the hub. some fans will notice the friction and shut off, then restart later.
Couldn't really hear anything in the 1st video (I'm on laptop speakers rn), but the second definitely sounds like coil whine, probably coming from the GPU (though I have seen coil whine come from a motherboard and PSU). There's no real way to fix it, cards either whine or they don't. It's not gonna damage the card or anything, basically every high end GPU I've had over the past 2-3 years has had pretty bad coil whine (my 6900XT is terrible) and they all work perfectly fine still.
It seems the bearings on one or more fans might be dry, causing noise from friction. Try pausing each fan briefly to check if the sound disappears, then replace the faulty one.
When a component stays firmly connected to the case, it may produce unusual sounds. If a fan isn't running properly, or PWM voltage is too low, a fan might stop working. Reduce power gradually, disconnect something, and restart until the issue resolves—coil whine will persist without fixing it.
