Scythe Kaze Flex 140 PWM

  • 140 mm PC fan with standard mounting space, the fan is ideal for computer case ventilation and water-cooling radiator.
  • 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 silent operation.
  • Included antivibration rubber pads covering each corner of frame. These decouplers effectively reduce possible vibrations and allow silent operation.
  • Newly designed blade and frame contribute high airflow with low noise, ideal thermal fan for computer case and CPU cooler/heatsink. PWM control offers wide range fan speed for various application and system.
