1.Better Heat Dissipation.3 x 120mm PWM fans to make sure excellent heat transfer from Computer Case and CPU. 2Classic blades design: 11-blade design, large air volume and pressure, the air volume up to 73.71 CFM, specially designed for water-cooled radiator. 3PWM automatic temperature control: 4pin PWM interface, mainboard automatic speed regulation, fan speed 800-1850RPM, minimizing noise or maximizing airflow. 4Silicone anti-vibration gaskets: reduce resonance noise, reduce fan vibration, and enhance installation stability. 5Double ball bearings: durable and good performance. Service life up to 80000H (MTBF) 6Compatibility. Good compatibility, not only can the chassis be used, but also can be compatible with CPU Liquid Cooler, providing strong thermal protection for the chassis and CPU.
