• 9-blade design offers a higher airflow and quiet cooling solution for the best performance.
• PWM capabilities built-in to precisely control the speed to achieve optimized fan curve.
• Rigid frame design and included rubber dampeners helps to prevent vibration.
• Low-noise operation without sacrificing performance.
• The hydraulic bearing design，it has a large oil storage space and an oil seal cover, which can reduce lubricating oil over flow, while reducing friction and noise.
