1.Better Heat Dissipation.3 x 120mm PWM fans to make sure excellent heat transfer from Computer Case and CPU. 2Multi curve blade design: dynamically adjust speed between 800 RPM to 2200 RPM, minimize noise or maximize airflow. 3Silent Cooling Technology: MAX air volume: 90.29 CFM. MAX fan noise: 35.7dB. Provide a quieter and longer lifespan cooling solution. 4PWM automatic temperature control: 4pin PWM interface, mainboard automatic speed regulation, fan speed 800-2200RPM±10%, minimizing noise or maximizing airflow. 5Silicone anti-vibration gaskets: reduce resonance noise, reduce fan vibration, and enhance installation stability. 6.Compatibility. 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.
