Single-Frame 420 mm Fan Unit

The NZXT F Series RGB Core combines three 420 mm fans in a single white frame. Fluid dynamic bearings and a 500 to 2,000 RPM range deliver 98.61 CFM airflow per fan at 34.5 dBA. An 8-pin connector handles both PWM control and RGB power at 11.99 volts and 11.4 watts.

Builders who want unified RGB lighting

This unit suits builders who want synchronised lighting across three fans without routing separate cables for each one. The semi-translucent blades carry eight RGB LEDs per fan and connect to NZXT CAM or a 5 V ARGB motherboard header via the included splitter. Buyers who need individual fan placement or non-RGB operation should look at separate single-fan kits.

420 mm radiator or case mount required

The frame measures 420 mm in length and 25 mm thick, so it only fits cases or radiators designed for that specific size. Mounting points follow the standard 420 mm pattern, and the single 8-pin cable reduces clutter behind the motherboard tray. Verify your chassis supports a 420 mm mounting location before purchase.

Questions about this item

Will the 420 mm frame fit in a standard ATX case without blocking the motherboard?

The single-frame unit measures 420 mm long and 25 mm thick, so verify your case supports a 420 mm radiator or fan mount before buying.

How loud are the three fans at full 2,000 RPM during an all-day render?

Each fan reaches 34.5 dBA at 2,000 RPM; combined noise will be higher but fluid dynamic bearings and Zero RPM mode keep idle volume low.

Does the 8-pin PWM and RGB cable plug straight into my motherboard or do I need an NZXT controller?

The unit includes a splitter for 5 V ARGB motherboard headers; for CAM software control an NZXT controller is required.
