Two 120 mm PWM fans with fluid bearings. Fan dimension: 120 mm. Connection: 4-Pin (PWM). Noise level: 27.5 dBA. Lighting: Yes. Minimum fan speed: 600 rpm, maximum fan speed: 2000 rpm. Slim 15 mm profile for small form factor cases. The fluid-bearing 120 mm PWM fans CORSAIR AF120 RGB SLIM are just 15 mm thick and provide impressive airflow and spectacular RGB lighting effects in compact builds where every millimeter counts. PWM-controlled fan speeds ranging from 600 to 2000 RPM result in powerful cooling, while eight individually addressable RGB LEDs per fan bring your system to life with brilliant lighting effects. Create stunning lighting effects with the included iCUE Lighting Node CORE controller to connect up to six RGB fans for easy, intuitive lighting control. The AF120 RGB SLIM operates particularly quietly at 27.5 dB(A), and thanks to support for Zero RPM PWM signals, the fan can be completely turned off to eliminate all noise. With its ultra-slim form factor of 120 × 15 mm, the AF120 RGB SLIM can bring compact cooling with RGB lighting effects to virtually any PC. PWM connection. This case fan allows for speed control via pulse width modulation using a PWM-capable motherboard. This dynamically adjusts the fan speed to the current operating conditions, minimizing unnecessary noise.
