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 unit with integrated fans streamlines installation, setup, and lighting control—no need to connect individual fans.
  • Simply connect a single cable to an NZXT controller (sold separately) for lighting and speed control via NZXT CAM software. Or, connect to any motherboard’s 5V ARGB header using the included splitter cable.
  • Fan blade design 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 across an exceptional 60,000 hour lifespan.
  • Eight individually-addressable RGB LEDs per fan hub are diffused through semi-translucent blades for brilliantly colorful visuals.
  • PWM-controlled fans dynamically adjust spinning speeds based on PC temperatures for optimal efficiency and reduced noise.
  • Anti-vibration rubber corners effectively eliminate noise caused by vibrations for hushed performance at any speed.
  • Control lighting and fan speeds via CAM software when connected to an NZXT controller (sold separately).

Frequently Asked Questions

Will the F420 RGB Core fit a 420 mm radiator?

The F420 RGB Core frame measures 420 x 140 x 26 mm, the footprint of a 420 mm radiator, and holds three 140 mm fans that mount as one piece. Each fan is rated at 3.2 mmH₂O of static pressure for pushing air through radiator fins.

How fast and how loud are the F420 RGB Core fans?

Each fan in the F420 RGB Core runs from 500 to 2,000 RPM (± 200 RPM) under PWM control and is rated at 34.5 dBA. The fans use a fluid dynamic bearing rated for 60,000 hours.

How do I connect the F420 RGB Core?

The F420 RGB Core uses one 8-pin connector that carries both PWM speed control and RGB lighting, on a single 600 mm cable. That means one cable to route for the whole frame. Each fan carries 8 LEDs.
