280mm dual-fan RGB unit

The NZXT RF-U28HF-B1 is a 280mm single-frame case fan unit containing two 140mm fans with RGB illumination. It connects via an 8-pin cable that carries both PWM and 5V RGB signals. Fluid dynamic bearings and a Zero RPM mode keep noise low when cooling demand drops. The black frame measures 280 by 140 by 26mm.

Suits radiator or front-panel 280mm mounts

Builders fitting a 280mm radiator or a front-panel slot that accepts a 280mm frame will find the integrated design simple to install. The package includes a 300mm PWM cable and a 100mm RGB splitter for motherboard connection. It is not for systems that require separate fan positioning or cases without a 280mm mounting pattern. Control via CAM software needs an NZXT RGB & Fan Controller sold separately.

98.61 CFM airflow per fan at up to 2000 RPM

Each fan delivers 98.61 CFM and 3.2 mm H2O static pressure at a maximum of 2000 RPM, with noise rated at 34.5 dBA. The 500 to 2000 RPM range lets the unit scale from silent idle to high airflow under load. If your cooling target needs more airflow or higher static pressure than these figures provide, consider a different solution.

Questions about this item

Will the 280mm by 140mm single frame with 26mm thickness fit my 280mm radiator mount?

The unit measures 280mm long, 140mm wide and 26mm thick, matching standard 280mm radiator mounting holes.

How do I connect the 8-pin power cable for both PWM control and RGB lighting?

Plug the single 8-pin cable into an NZXT RGB & Fan Controller for CAM control, or use the included 300mm 4-pin PWM and 100mm 5V RGB splitter cables to connect directly to motherboard headers.

When should I expect to service the fluid dynamic bearings on the two 280mm fans?

Fluid dynamic bearings are sealed and rated for continuous operation across the 500 to 2000 RPM range; no routine lubrication or bearing replacement is required.
