MORE LIGHT. MORE CONTROL.

Ultra RGB fans that do more than glow—they bring your build to life. Multi-zone lighting dances across your setup with depth and motion, while whisper-quiet PWM cooling keeps your system calm.

CONTROL WITH CAM

Fan curves, thermal monitoring, and RGB personalization—everything in a single interface.   Requires NZXT Control Hub or NZXT motherboard (sold separately).

OPTIONAL DIRECT MOTHERBOARD CONTROL

Connect to a 5V ARGB header for basic lighting and fan control. Check LED compatibility.

PRECISE AIRFLOW

Aerodynamic blades and a precision-engineered frame move airflow through radiators and mesh.

WHISPER-QUIET COOLING

Stays under 37 dB at full speed with fluid dynamic bearings and anti-vibration corners.

Frequently Asked Questions

What makes the Ultra RGB range different?

Lighting density and airflow. The F140U carries 64 LEDs on a 7-blade rotor and moves 92.2 CFM at 5.1 mmH2O, the strongest static pressure in the NZXT fan range.

Speed runs from 500 to 2,400 RPM, reaching 36.9 dBA at full tilt.

How quiet is the F140U in normal use?

At a 27 dBA noise target it settles around 1,700 RPM and still moves 61.73 CFM at 2.86 mmH2O.

That is more airflow at 27 dBA than the F120U manages, which is the practical argument for fitting 140 mm where your case allows it.

How do I connect and control the F140U?

It ships with a 4-pin PWM lead and an NZXT 4-pin RGB connector, and also supports a 3-pin 5V ARGB header. Two 600 mm cables and an adapter cable are included.

Pair it with an NZXT controller for full effect control in CAM, or a 5V ARGB header for basic motherboard control.

How long does the F140U last?

The fluid dynamic bearing is rated for 60,000 hours, and the fan carries a 5-year warranty.
