Review on 🖥️ SXDOOL 120mm Slim Fan - 120X12mm Thickness - DC 12V - 3-Pin - Computer PC Case Cooling - Quiet Silent Performance by Dewey Tory

I bought two of these units to mount in the bottom of Lian Li's Tu150 to cool a large Radeon GPU. After a few weeks I started noticing this hum. I thought it was the GPU or maybe a large intake fan. nope It was these little bugs. Worse, sometimes they stumbled, then out of sync with each other, causing an annoying resonance. I replaced them with Noctua 15x120s, which make no noise at all and push out the same amount of air. Even though they cost twice as much. You are not terrible. If you listen to music, you probably won't even hear it. Definitely worth the asking price. Hope that helps.
