Enhanced Airflow, Reduced Noise: A 5mm thicker fan blade enhances cooling by moving more air at the same speed as thinner fans, while reducing noise since the RX MAX can spin slower to produce the same airflow. PWM Controlled Speeds via iCUE LINK: Set precise fan speeds up to 2,000 RPM while providing up to 71.3 CFM airflow to your system. High Static Pressure: With 4.16mm-H2O of static pressure, the RX MAX RGB Series is great for pushing air through obstructions such as high-density radiators. Vivid RGB Lighting: Eight RGB LEDs display vivid lighting effects, with a window built into the frame to enable viewing of your lighting from the side. LINK Your Fans Together: The included iCUE LINK bridge connectors can connect your fans directly to each other, creating a seamless bank of fans all connected to the iCUE LINK System Hub with just a single cable.
