Phanteks PH-F120S 120mm premium fans are designed using the unique Maelström concept technology. With its’ nine blades and MVB feature, it will produce a powerful yet silent downdraft airflow. Long lifespan and rotation stability is made possible with the UFB bearing, composed by MOSS and SSC systems. PH-F120S is setting a new standard of performance and compatibility.

MVB (Maelström Vortex Booster)
The nine blades are positioned in a way that it provides a powerfully controlled airflow. The MVB produces a downdraft vortex allowing air passage through the surface to produce a significantly better performance while keeping the noise level down. |

UFB bearing (Updraft Floating Balance bearing)
Phanteks’ UFB bearings are composed by MOSS and SSC system. MOSS has an effective fan hub-blade ratio to achieve a dynamic balance, thus floating the axis for minimal air noise. SSC increases the bearing life span to ensure that the fan axis is consistently operating without mechanical noise. |
