The fan "wind blowing" noise gets louder for every fan you have onscreen at once in the editor. When working on a large room with many fans, its very loud. I think it should stop scaling its volume at like 2-3 fans. You can hear the volume progressively increase in the attached video.

it logically makes sense that the fans get louder adding their noise together, but it's too much in the editor compared to other sounds
