Nzxt RF-U28HF-B1 Case fan Black (RF-U28HF-B1)

The NZXT RF-U28HF-B1 (F280 RGB Core) is a high-performance, aesthetic computer cooling solution featuring a single 280 mm frame housing two 140 mm PWM fans with RGB lighting. Designed for enthusiasts and gamers, it offers excellent airflow and static pressure, combined with stylish RGB illumination and simplified installation. With dual 140 mm fans integrated in one frame, it reduces cable clutter, supports ARGB lighting and offers both intake and exhaust roles in large PC cases.

Technical Specifications:

• Model: RF-U28HF-B1 (F280 RGB Core)

• Fan size: Two × 140 mm fans in a 280 mm frame. 

• Speed: approx. 500 – 2,000 RPM per fan. 

• Maximum airflow: ~ 98.61 CFM per fan. 

• Static pressure: ~ 3.2 mm H₂O per fan. 

• Noise level: ~ 34.5 dBA per fan (at full speed).

• Bearing type: Fluid Dynamic Bearing (FDB) for longer life and quiet operation. 

• Frame dimensions (approx.): Height 280 mm × Width 140 mm × Depth 26 mm. 

• Power consumption: 12 V DC, 0.59 A (≈7.08 W) per unit. 

• RGB: Yes — ARGB lighting (8 LEDs per fan hub) and semi-translucent blades.

• Connector: 4-pin PWM + RGB header.

• Application: Ideal for large cases requiring strong airflow or radiator front/intake with RGB styling.

Usage & Benefits:

• The single-frame design with dual fans simplifies installation — rather than mounting two separate fans, you mount one integrated unit.

• High airflow and static pressure make it effective for moving large volumes of air or pushing air through restrictive space (e.g., dense radiators or front-intake grills).

• ARGB lighting and modern styling make it a good choice for showcase builds.

• PWM speed control allows the fans to slow down or even stop (Zero-RPM mode) under light load, reducing noise when the system is idle.
