  • Newly designed blade and frame contribute high airflow with low noise, ideally for computer case, radiator and heatsink. PWM control offers wide range fan speed for various application and system.
  • Sealed Precision Fluid Dynamic Bearing: the bearing and the spindle are made of high-quality compressed metal and are lubricated by a special oil film resistant to temperatures of up to 250C°/480F°. This drastically reduces friction, ensuring smooth operation and reduced wear, which results in long life span and quiet operation.
  • Included antivibration rubber pads covering each corner of frame. These decouplers effectively reduce possible vibrations and allow silent operation.
