Optimized Fan Design:
- High Performance:High airflow and large volume cooling by blade design,super silent.
- Long Working Life: Hydraulic bearing takes closed type design and loop back type lubricant supply circuit, has larger lubricant storage space and long using life, the service life is longer than 40000 hours.
- Easy Install:120mm fan tuned for high-airflow and large volume cooling.
- Optimized Cooling:Optimized fan blades for balanced air pressure and airflow.
- High Static Pressure: Provides improved performance over standard case fans.

Optimized Cooling
Optimized and enhanced static pressure for better cooling performance.

Hydraulic Bearing
Wear resistant hydraulic bearing construction makes the fan run noiseless and the air volume larger.

9 Fan Blades Design
With 9-blade design,the appearance is more beautiful, balanced air volume and wind pressure, providing strong heat dissipation.


Tips:
- Compatible 3PINconnector for motherboard and power supply that also works withMolex 4 PIN headers.
- *4PIN and 3PIN cannot be connected at the same time to avoid a short circuit!
