Key Features
Whisper-Quiet Operation: Runs at 400 to 1600 RPM with up to 57.56 CFM of airflow and only 25 dBA noise at full speed. You get strong cooling with a peaceful gaming setup.
Steady RPM Technology: A closed-loop control system maintains stable RPM and airflow. This gives consistent, reliable cooling for PCs, air coolers and liquid cooling systems.
Advanced P/Q Curve: Designed to deliver optimal airflow and pressure. This makes the fan a good fit for radiators, air coolers and all-around case cooling.
Optimized 1 mm Tip Clearance: A precise blade-to-frame design boosts airflow and minimizes leakage. The result is efficient cooling with less turbulence and noise.
Anti-Vibration Pads: Molded pads cover 80% of each corner to absorb vibration. This keeps your system quiet and stable, even at high RPM.
4-Pin PWM Connector: Lets your motherboard control the fan speed automatically. Speed follows system temperature, so noise stays low when the load is light.
Hydraulic Bearing: A hydraulic bearing supports smooth rotation. This helps the fan run quietly and reliably in daily use.
