Hi guys, yesterday everything was working perfectly fine, but this morning it looks like my BIOS got reset or something happened, and my PC started making some hissing noises.

Full specs: https://pcpartpicker.com/user/Ley01/saved/GRP9GX

It might be the GPU (RTX 2060 Super), except when I stress test it, or my CPU, there are no hissing noises. But when I open PC Building Simulator (yeah...), the noise starts. It doesn't happen on every game, only 1 or 2 out of 4 I've tested.

I'm ready to RMA anything if needed. If it's coil whine, I know it's not dangerous but I need my PC to be as silent as possible.

Thanks for your help.
 
Solution
Yup, sounds like coil whine. You can usually make this happen in games by lowering the in-game video settings (and disabling VSync) to produce very high FPS.
