Mvb2 maelstrm vortex booster the new seven high pressure mvb blades are precisely angled to generate a silent controlled airflow the blades produces a downdraft vortex allowing for greater amount of air passage through and reduce airflow turbulence across the surface of the blades to create significantly better performance and airflow while keeping noise to a minimum ufb bearing updraft floating balance bearing phanteks ufb bearings are composed by moss and ssc system moss has an effect
