NZXT F140 RGB DUO 140mm Dual-sided RGB Fan with RGB Controller, Fluid Dynamic Bearing. RGB Lighting, Up to 1800 RPM Speed, 84.75 CFM Airflow, Quiet and Cool, Twin Pack, White | RF-D14SF-W1

The F140 RGB DUO represents a calculated fusion of NZXT’s sophisticated industrial design and advanced light-diffusion technology. Unlike standard fans that only illuminate one side, the DUO series features high-intensity LEDs on both the inner and outer rings, visible from both the front and back of the mounting point. This provides a profound functional advantage: whether you are mounting these as intake fans at the front of your chassis or as exhaust fans at the top/rear, the vibrant RGB glow is perfectly visible from any angle, ensuring that your lighting configuration remains consistent and immersive throughout your entire PC interior.

Optimized Airflow and PWM Precision
At the interactive core of its mechanical layout is a refined fan blade profile engineered for high-static pressure and efficient airflow. By optimizing the blade surface area and curvature, this 140mm fan is capable of pushing significant volumes of air through restrictive case mesh or dense radiator fins, ensuring that your high-end CPU and GPU stay within their thermal comfort zone. The PWM (Pulse Width Modulation) control allows for intelligent speed modulation, ensuring that your fan remains whisper-quiet during low-intensity tasks and only ramps up to its maximum 1,500 RPM during intensive gaming or rendering marathons.

Reliable Fluid Dynamic Bearing
Meticulously optimized to seamlessly integrate into modern showcase builds, the F140 RGB DUO is built to endure years of heavy operational loads. It features fluid dynamic bearings, which provide the exact mechanical framework required for years of silent, vibration-free operation. This ensures that your system remains whisper-quiet during low-intensity tasks and maintains reliable performance during marathon sessions. Combining high-end aesthetics with refined airflow utility and a durable, sleek matte white finish, this fan stands as the premier selection for users who demand the perfect balance of visual customization and reliable system thermals.
