The NZXT F280 RGB Core (model RF-U28HF-B1) is a 280 mm single-frame RGB case fan unit designed for PC cooling. It integrates two 140 mm PWM fans in one frame for simplified installation and high airflow, delivering up to 98.61 CFM with a max speed of ~2000 RPM. The fans use fluid dynamic bearings for quiet, stable operation and include addressable RGB lighting that can be controlled via NZXT CAM or connected to a motherboard’s 5 V ARGB header. The unit features anti-vibration mounts, customizable lighting, and a sleek black design suited for gaming and enthusiast builds

The NZXT F280 RGB Core (model RF‑U28HF‑B1) is a 280 mm single-frame RGB case fan unit designed to deliver efficient cooling and striking lighting for PC builds. It integrates two 140 mm PWM fans in a single frame, simplifying installation and reducing cable clutter compared to separate fans. Cooling Performance: Dual 140 mm PWM fans with speeds from 500 to 2,000 ± 200 RPM automatically adjust to system temperatures for efficient airflow and cooling. Each fan delivers up to 98.61 CFM of airflow and 3.2 mm H₂O static pressure, suitable for intake, exhaust, or radiator mounting. Fluid dynamic bearings provide a long lifespan (~60,000 hours) with quiet, stable operation. Anti-vibration rubber corners reduce noise, and Zero RPM mode can silence fans under light loads. Lighting & Control: Each fan features 8 individually addressable RGB LEDs for dynamic lighting effects. Includes an 8-pin combined PWM and RGB connector and a splitter cable for motherboard 5 V ARGB headers. Lighting and fan speed can be managed via NZXT CAM software when connected through a compatible NZXT controller (sold separately). Design & Compatibility: Integrated single-frame design simplifies mounting in cases with 280 mm fan/radiator support. Sleek black finish and RGB lighting enhance gaming and enthusiast PC builds. Includes necessary mounting screws and comes with a 5-year warranty. Summary: The RF‑U28HF‑B1 provides high-performance airflow, quiet operation, and customizable ARGB lighting, making it ideal for improving both the cooling and aesthetics of modern PC systems.
