Fan NZXT F420 RGB Core 14 cm Black Fluid Dynamic Bearing

The NZXT F420 RGB Core is a 140 mm single-frame cooling fan unit with integrated RGB lighting and Fluid Dynamic Bearing designed for PC cases. The all-in-one frame contains multiple fans for simplified installation and unified lighting control. The blades and frame include semi-translucent elements that allow 8 addressable RGB LEDs per hub to produce even, customizable lighting while the blade geometry increases static pressure to move air effectively through radiators and tight case areas.

Advantages

The single-frame design streamlines installation and cable management by presenting one connector for multiple fans. Fluid Dynamic Bearings provide low noise, high rotational stability and a rated 60,000-hour lifespan. PWM support enables automatic speed adjustments based on system temperature, while anti-vibration rubber corners reduce operational noise. Zero RPM Mode stops the fans under light load for silent idle operation. Connectivity options include an NZXT controller (sold separately) for CAM software control or direct connection to a motherboard 5V ARGB header using the included splitter cable.

Suitable for

• Case cooling in mid-tower and full-tower PC builds
• Push or pull configurations on radiators and AIO coolers
• Systems requiring synchronized ARGB lighting effects

How to use

Install the single-frame fan unit into your case in the desired location using the provided mounting points. Connect the unit to an NZXT controller (sold separately) with the single cable to manage lighting and fan speed via NZXT CAM, or use the included splitter cable to attach to a motherboard 5V ARGB header for lighting control while connecting the PWM cable to a fan header for speed control. Ensure the airflow direction matches your cooling layout (intake or exhaust) and secure cables to avoid contact with blades.

Recommendations

For radiator use, position the F420 RGB Core in push or pull orientation according to your cooling setup and monitor temperatures after first boot to confirm PWM curve settings in CAM or your motherboard BIOS. Use the included splitter only with compatible 5V ARGB headers and follow your motherboard manual to avoid overloading headers.
