Question Background buzzing noise in games ?

Sep 18, 2021
Hey everyone, so recently I upgraded my PC to the configuration below without changing the GPU for now due to supply issues and huge prices in my country. I went with the idea that until I find a proper gpu even if prices are a little higher, ill just play some decent games like CS:GO, GTA and a little bit of Forza Horizon on low/medium settings so I dont go too hard on such a bottlenecked setup.

The problem I have is that i got a buzzing noise in the background whenever I disable VSYNC in any game. I would assume its only because of the bottleneck so the GPU tries to work harder? It never happened on the old setup.
Also tried to reinstall audio drivers and do all kinds of things software related to fix it but no luck so what I said previously is my only assumption right now.

Current setup:
16GB Crucial Ballistix 3600mhz CL16
Asus Z490-A Prime
Arctic Liquid Freezer 360mm
Gigabyte GAMING OC GTX 970

Old setup:
8GB HyperX Fury 2133Mhz
A gigabyte motherboard, cant remember the model
Gigabyte GAMING OC GTX 970
