NZXT F420 RGB Core — 420mm Single-Frame RGB Fan Unit (White)

3× 140 mm in one frame98.61 CFM per fan24 ARGB LEDs5-Year Warranty

The NZXT F420 RGB Core (part number RF-U42HF-W1) is a white 420 mm single-frame fan unit with three 140 mm PWM fans and addressable RGB lighting, designed for full-tower builders running 420 mm radiators or large front intakes.

Larger 140 mm blades move up to 98.61 CFM per fan at a lower top speed than 120 mm fans, and the single frame means one mounting step and one cable. Typically in stock with fast delivery across Cyprus.

Compatibility Note
Requires a 420 mm (3× 140 mm) mounting position or a 420 mm radiator — check your case support before ordering. The unit uses a single NZXT 8-pin cable (PWM + RGB): NZXT CAM control and Zero RPM mode need an NZXT controller or NZXT motherboard (sold separately); otherwise connect to a motherboard PWM header and a 5 V 3-pin ARGB header with the included splitter. Not compatible with 12 V 4-pin RGB headers.
Best For
✓ 420 mm AIO radiators
✓ Full-tower front intake
✓ White themed builds

Frequently Asked Questions

Does the NZXT F420 RGB Core work with any motherboard?
Yes — with the included splitter it connects to a standard 4-pin PWM fan header and a 5 V 3-pin ARGB header. NZXT CAM control and Zero RPM mode require an NZXT controller or NZXT motherboard.
Will the F420 RGB Core fit my case?
Only if the case supports 3× 140 mm fans or a 420 mm radiator in one row. Many mid-towers only fit 360 mm, so confirm the case specification first.
What is the difference between the F420 RGB Core and the F360 RGB Core?
The F420 uses three 140 mm fans (98.61 CFM each, up to 2,000 RPM), while the F360 uses three 120 mm fans (75.12 CFM each, up to 2,400 RPM). Choose by the radiator or mounting size your case supports.
What do I need to know before buying the RF-U42HF-W1?
Confirm 420 mm clearance, and plan an NZXT controller or free PWM + 5 V ARGB headers for connection.
Singular Expert Insight
For big white builds with a 420 mm radiator, the F420 RGB Core gives the most airflow per decibel in the F Series Core line thanks to its 140 mm blades. If your case tops out at 360 mm, the F360 RGB Core is the right choice; browse more options in our case fans category.

Buyer's Guide

Buy it if
Your case or AIO supports 420 mm and you want high airflow with one-cable wiring.
Skip it if
Your case only fits 360 mm or 120 mm fans.
