D8 Hybrid high-pitched coil whine

[bitfidelity]

Is anyone else experiencing this? I think it's coming from the power supply, but I'm not sure. And I don't think it's the 12 TB WD Red Plus HDD that's installed, as it makes no such noise with my external dock.

For sure it is the power supply, because i have the same with the D2-320.
It is hearable if you are close with the head at the power supply (around 50 centimeter / 19 inch).
sounds a little bit like bird chirping.

I see. Anyone have any suggestions on a silent one that I can replace it with?

I ended buying this:

And there's no coil whine.

I can still hear a slightly high-pitched tone when I put my ear really close to the unit, but I'm pretty sure that's the WD Red Plus HDD that I have installed.
