Performance & Silent Balance: Design combines performance and quiet, ideal both as a case fan and for CPU coolers, water-cooling radiator, 69.11CFM, 2.92 mm H2O, 4-pin PWM, max. 29 dB(A) Squama particle Patent: Squama particle on the frame, reducing turbulent flow noise increases airflow and pressure efficiency PWM: 4-pin PWM controlled fan speed from 800 to 2000 rpm, with excellent balance of performance and quietness, pushing up to 69.11 CFM of air with 2.92mm- HO of static pressure. ARGB Dual Light Loop: The dual light ring equips 18 separately Addressable RGB LEDs can synchronize lighting with motherboard, lighting effects are individually customizable. Also provide additional controller if the motherboard doesn't support, that allow you could create your own immersive lighting effects without technical obstacle (7 lighting modes, 8 static colors). Shockproof: Anti-vibration rubber pads can prevent scratches and further reduce noise from fan spinning at a higher level.
