I get ya. I have a pair of noise cancelling Sony in ear headphones and just tried putting my head next to the machine and couldn't hear anything - especially over the in game audio. To be honest mine is barely audible with the panel on - even with my head right next to the machine. Can definitely hear it with the panel off though. Here's a video;

Its always hard to capture on video. I find mine sounds much worse in real, compared to a video I made of it.
Yours doesn't sound so bad in that video at least.
I had a 2080Ti FE which was a pretty enclosed design like the 30 series. Coil whine was there but it wasnt crazy, audible but not too bad. Fitted waterblock and it was like a coffee grinder because the chokes were far more exposed.
Most of the AIB cards were pretty bad also, worse than the FE anyway. Must have gone through 10 cards hoping for a silent one but it just isnt possible and i accepted it in the end. Undervolting did help a tonne but in the end just moved my pc away. Was driving me crazy to the point of buying a console crazy. Now pure silence what ever the situation. Best decision ever.
Its crazy how coil whine is such a lottery...
In all the GPUs I have owned till the 30 cards, I have never had it bad. Just at really high FPS in a game menu.
But seems that its far more common now. I was planning to keep hunting and trying for an AIB card to hope to get past the whine... but it seems that might be a futile effort. Esp in the current climate where you cant just buy the card you want....
