You've got 3090 SLI?
Yup.. it's been updated more since with larger 20TB drives and larger NVME drives but apart from that looks the same. Can see here :-

my 3090 strix had zero whine until i put an EKWB water block on it, now its super loud like you describe Can be: previous thermalpad would be right on the spot applying some pressure and acting as a dampener or the fans were masking the coil whine. Mine happens on Assassin's creed, not a lot...
