Noises since upgrade

Hi,
I recently upgraded my GPU and CPU + cooling fans. I use the system primarily for MSFS in VR.
I've got a weird issue that when I've been in VR for a short time and the system is stressed there is a noise coming from the PC that sounds like a wire is touching the top mounted fans. If I come out of VR the noise disappears and likewise, if I remove the side panel of the PC it also doesn't happen. I can't tell if the noise is electrical or physical.
I have a recording of it on my phone but not sure how to upload it here.
Just looking for some suggestions on how to diagnose please.

Steve

I'd suggest you want to strip away as much as possible and then re test by adding stuff back in. For example, if it is something to do with the fans, disconnect them and then retest.

It's also possible it's coil whine from the GPU or something similar, which you can't really do anything about.

I watched a YT movie to see what coil whine is - this noise is way louder than that. Actually just uploaded it to youtube:

I personally would run it with the side panel off and with my ear as close as i can to try to identify exactly where the noise is coming from

Yeah when the side panel is off the noise doesn’t appear at all. That’s part of my issue

Does the sound go away if you hold the side panel of the case, or just if you take it off?

Only if I take it off or if I come out of VR then it will go after 5-10 seconds.

How is the panel attached on the case? Is the fitting tight, is there any give? Only other thought i've had now is whether it's some sort of vibration coming from the fans and is rattling the side panel somehow.

Yeah it's not a vibration - checked that also. I really think it's the fans but no idea what could cause it. I had the fans fitted as wasn't sure how to do it from a cables perspective but I'll have to get it checked out again
