Need an expert's opinion

So, I built my third PC like a month ago. I went with a big budget to create my dream build. My specs are down below.

The issue is : the day I started to use my PC, I noticed weird buzzing sounds. As time passed, it became more and more annyoing. To explain, every little movement I do with my mouse creates sort of a buzzing sound coming from the motherboard area (I put my ear as close as possible to identify where the noises from, and it really comes from around the CPU). + whenever my CPU is under load, the same kind of noise happens, but at a higher volume. In addition to that, my GPU has a ton of coil whine, even undervolted. 

Im in a desperate need of help, since I dont know what to do. I spent a lot of time and a lot of money for this build to be my work/gaming station, and as it is right now it's very unpleasant to use...

 

Thanks to anybody reading this.
