ASRock B450 Steel Legend whine/buzzing noise from VRM area HELP

So first I noticed slight whining noise when my pc was off and after some investigation came to conclusion its from the motherboard.

Today when the pc was under some load that similar noise was much more stronger and audible.

I tried absolutely everything, CPU is even undervolted slightly from stock, frequency stock, memory set to 3200 1.35V, nothing too special. Updated BIOS. 

Ran AIDA all running good and has been for the past few weeks since I built it. Checked everything and its 100% the motherboard.

PSU does make some buzzing noise while off too, maybe because of the 5V standby thing it has, not sure either, guessed that caused motherboard to pull some power aswell.

Only thing Im worried about is it anything harmful or just regular coil whine? I can hear it but its mostly audible when I put my ear up to top of the case.

Just regular coil whine, I dont think a board can make whiney sounds that indicate something dangerous. When something really.goes bad, either it.doesnt make any noise or.it goes pop
