Cable Length: 400 mm Features:-MVB (Maelstrm 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. -Polarity Auto-Restart ProtectionPhanteks unique fan circuit design provides a Fan Polarity Auto-Restart feature.The sensor inside of the fan will constantly send a series of rectangular signals to your PC M/B indicating that the fan is working correctly. The unique restart feature provides optimal support and protection. -Speed Settings by Unique Q.S.A adapters and Anti-acoustic kitsPhanteks PH-F140TS comes with unique Q.S.A adapters for 1200, 900 and 750 rpm speed setting flexibility.Anti-Vibration compensators and rubber pads, eliminate the buzzing sound and absorb the
