About 2 months ago I got a new HyperX headset but shortly after I noticed a weird noise in my clips that did not exist before. You can hear it in the background of the clip I posted. I would post clips of different things so it would be easy to distinguish the noise but unfortunately Reddit doesn't allow more than one video in a post.
I disabled my mic to see if that was the issue and it was not. I tried other recording software and it was the same. I tried recording with just the video and my mic and the noise wasn't there.
Another thing I noticed from multiple recording tests is that the noise is only there when there is sound coming from whatever game is being recorded. For example, even in the same clip the noise is only there when there is stuff happening in the game, so making noise but isn't there when the game is quiet. This leads me to believe the noise is directly correlated with sound in clips.
