[SOLVED] PC making annoying noise when playing demanding games ?

[nirdekel1]

Hello, I have a i7 930 CPU with Radeon R9 290 GPU and 8GB DDR3 RAM.

During the last months my PC started making an annoying noise, only when i play high profile games like Red Dead Redemption 2, Assassins Creed Valhalla, and more..
Because of that, the immediate suspect for making that noise was the GPU fan. Therefore I tried stressing the GPU to Max on MSI Afterburner for about 30 minutes but the PC remained silent.

I tried figuring out where the noise came from but couldn't determine. I took 2 videos of the pc with and without the noise so it can be distinguished.
Anybody have an idea where this noise comes from?
Thanks

Sounds a lot like fan bearing noise or when something (wire) is barely against spinning fan blades. As from where it comes from, impossible to tell from your video but suspects are: PSU fan, case fans, CPU cooler.
