DIGITAL A-RGB: The 12 A-RGB LEDs placed along the fan hub and the transparent rotor, with its enclosed design, provide even and rich illumination EASY TO COMBINE: Both the fan and A-RGB cables have an integrated Y-splitter, making it even easier to retrofit and control additional fans OPTIMIZED FOR STATIC PRESSURE: Thanks to its high static pressure, the fan guarantees efficient cooling, even with increased air resistance. Suitable for use on heat sinks & radiators 200-2000 RPM (0 RPM <5 %): Thanks to 4-pin connector, the rpm can be regulated in a broad spectrum via PWM, noise is kept at a minimum while maximum cooling performance is given when needed SPECIFICATIONS: 3 Pack; Fan speed: 200-2000 rpm (0 rpm <5 %); Airflow: 48.80 cfm | 82.91 m³/h; Static pressure: 1.85 mmH₂O; Noise level: 0.3 Sone; Fan connector: 4-pin; LED connector: 3-pin
