My stock EK backplate, looked exactly like the picture you showed when the first manual was posted on their website. That is how mine is currently configured. If you look at the manual now, it looks a lot different. The VRM pads were originally 1mm thick, they're now 2mm. Theres also additional pads around the ram (shown in red). It will be interesting to see if this has solved the issue. Failing that I do have the Aquacomputer Kryographic due to arrive mid February with active back plate and there's always the EK active back plate later on down the line. I've not heard good things about the Aquacomputer one though.

I checked my EVGA backplate and there was no thermal pads at all on there, the backplate seems purely cosmetic. I looked at your EK backplate and yes there is a ton more thermal pads, interested to see if the revision changes anything for you.
As it stands for my loop I am happy now that the coil whine has gone and as the stock card didnt have any thermal pads for the back plate I am not really concerned about not having pads in that area.
Literally worked on my 4090.
I always ran it at 75% power limit for obvious power/performance reasons, and it's always sounded like an angry bees nest but never really bothered me, I don't hear it over the fans when gaming anyway.
I set the power limit to 100%
ran heaven benchmark maxed out at 3440x1440 full screen.
The first 5 minutes it was quite loud, then suddenly the scream dropped by probably 65%, I left the benchmark running another 5 minutes and it just stayed the same the whole time.
stopped it and let the card cool back down and tried again, and it never went back to the original scream.
I'm not sure if it was heaven benchmark or me pushing on bits of the card though.
it's definitely an electrical buzz so the coils in the ferrite chokes or whatever. but pushing gently on parts of the shroud/backplate seem to make it go quieter?!?!?!
could all be a big coincidence, even touching parts of the plastic fan housing seemed to make it quieten down a bit at times, but other times seemed to be nothing more than wishful thinking and did nothing.
but pushing the card harder into the pcie slot seemed to make it quiet a bit, and the same when pushing on the power cables going into the card even though they are fully seated.
it makes me think something of the card was vibrating in harmony with the coils and amplifying it? or heaven legit vibrated the coils enough to kinda settle them into a better shape where they don't buzz so much.
I'm 100% sure the card has always been fully in the pcie slot and the power cables were definitely 100% plugged in or would have melted by now.
Either way something made a huge difference.
Why don't they just prefill the chokes with glue? surely it costs about 0.01pence

Didn't notice this was an old thread
Nice to see it can work for some people, I despise coil whine and this sort of fix has never worked for me sadly.
best trick is to get old then you cant hear it anyway
