## Key Features

- 140mm 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.
