The audio in the video doesn't state much apart from the noise. You might want to roll up a sheet of A4 paper, then hold one end to your ear while the other end is used to inspect/probe for the source/origin of the noise.

Might also want to include the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Please include the age of the PSU apart from it's make and model.
