Overview

NZXT F Series RGB Core single-frame fans seamlessly integrate multiple fans for effortless installation while offering superior cooling, whisper-quiet performance, and striking RGB visuals.

Single-Frame Design: Integrated fans streamline installation, setup, and lighting control—no need to connect individual fans.
Versatile Connectivity: Connect a single cable to an NZXT controller (sold separately) for lighting and speed control via NZXT CAM software, or to any motherboard's 5V ARGB header using the included splitter cable.
Optimized Fan Blades: Boosts static pressure to push air through tight spaces while ensuring optimal airflow, suitable for both intake and exhaust.
Fluid Dynamic Bearings: Ensure quiet, stable operation with an exceptional 60,000-hour lifespan.
Vibrant RGB Lighting: Eight individually-addressable RGB LEDs per fan hub, diffused through semi-translucent blades for brilliantly colorful visuals.
PWM Control: Dynamically adjusts spinning speeds based on PC temperatures for optimal efficiency and reduced noise.
Anti-Vibration Design: Rubber corners effectively eliminate noise caused by vibrations for hushed performance at any speed.
CAM Software Integration: Control lighting and fan speeds via CAM software when connected to an NZXT controller (sold separately).
