Electrical Connection
The F420 RGB Core offers flexible connectivity options for fan speed and RGB lighting control.
- Option 1: NZXT Controller (Recommended for full control)
Connect the fan unit's main cable to an NZXT RGB & Fan Controller (sold separately). This allows for comprehensive control over fan speeds and RGB lighting effects via the NZXT CAM software. - Option 2: Motherboard 5V aRGB Header
Use the included splitter cable to connect the fan unit to a compatible 5V addressable RGB header on your motherboard. This enables basic RGB control through your motherboard's software. The fan power cable (4-pin) should be connected to a fan header on your motherboard.

Operating Instructions
Once installed and connected, you can manage the performance and aesthetics of your F420 RGB Core fan unit.
Fan Speed Control (PWM)
The fans support Pulse Width Modulation (PWM) control, allowing for dynamic adjustment of fan speeds based on system temperatures. This optimizes cooling efficiency and minimizes noise.
- If connected to an NZXT controller, use the NZXT CAM software to set custom fan curves, select preset profiles, or enable Zero RPM Mode for silent operation under light loads.
- If connected directly to a motherboard fan header, fan speed control will be managed by your motherboard's BIOS/UEFI settings or its proprietary fan control software.

RGB Lighting Control
The F420 RGB Core features 8 individually addressable RGB LEDs per fan hub, offering extensive customization.
- Using NZXT CAM Software: If connected to an NZXT controller, the CAM software provides a wide array of lighting effects, color customization, and synchronization options with other NZXT RGB products.
- Using Motherboard Software: If connected to a 5V aRGB header, use your motherboard's RGB control software to manage lighting effects.

Maintenance
Regular maintenance ensures optimal performance and longevity of your fan unit.
- Dust Removal: Periodically clean the fan blades and frame to prevent dust buildup, which can impede airflow and increase noise. Use compressed air or a soft brush. Ensure the system is powered off before cleaning.
- Bearing Longevity: The fluid dynamic bearings are designed for a long lifespan (60,000 hours) and require no lubrication.
Troubleshooting
If you encounter issues with your NZXT F420 RGB Core fan unit, refer to the following common solutions.
- Fans Not Spinning:
- Check all power connections to ensure they are securely seated.
- Verify that the fan header on the motherboard or controller is supplying power.
- If using NZXT CAM, ensure fan profiles are not set to Zero RPM Mode when cooling is expected.
- RGB Lighting Not Working or Incorrect:
- Ensure the RGB cable is correctly connected to either the NZXT controller or the motherboard's 5V aRGB header.
- Check the NZXT CAM software or your motherboard's RGB software for correct lighting settings and profiles.
- Confirm that the 5V aRGB header on your motherboard is enabled in the BIOS/UEFI.
- Excessive Noise:
- Inspect for any cables or obstructions touching the fan blades.
- Ensure mounting screws are tightened appropriately to prevent vibrations.
- Adjust fan speed profiles in NZXT CAM or motherboard software to reduce RPMs if noise is a concern and temperatures allow.
