Momentum is a fan series which fuses premium materials with high standards of engineering to minimize noise while maximizing cooling efficiency. It features a swept blade design, vibration-reducing rubber bushings and true fluid dynamic bearing technology to ensure quieter operation. Momentum blades are constructed from Liquid Crystal Polymer (LCP), which reduces the required distance between the fan’s rotor and frame to further improve efficiency. Highly stiff Liquid Crystal Polymer (LCP) blades, allowing smaller gaps between rotor and frame Updated swept blade design improving performance per noise, especially at higher speeds True FDB bearing with inner herringbone structure provides optimal noise performance as well as increased lifetime Large-range PWM control allows the fan to both spins quietly at lower loads while providing great headroom during high loads The fans can be turned off entirely (zero-RPM) for total silent operation Rubber bushings around all screw points to reduce
