Fan set NZXT RF-AR140-C1 140MM RGB

This is a set of two 140 mm RGB fans NZXT RF-AR140-C1, aimed at mid-range to more serious gaming and enthusiast cases, where you want both stable cooling and a clean visual effect. Each fan uses a dynamic fluid bearing and operates in a range of 500–1500 RPM, providing a good balance between airflow and noise. The addressable RGB lighting allows you to customize effects per individual diode, and the included digital RGB controller saves you the hassle of figuring out how to connect them. The color is classic black, so the fans visually fit most builds.

What you get

With this set, you get two 140 mm fans capable of providing airflow between 30.39 and 91.19 CFM, which is more than enough for good circulation in a standard or larger case. Thanks to the 4-pin PWM connector, you can precisely control the RPM according to temperature – keeping them around 500 RPM for nearly silent operation in idle and reaching up to 1500 RPM under heavier load. The noise levels between 22–33 dBA mean that even at higher speeds, they won't be annoyingly loud to the ear. The dynamic fluid bearing helps for smoother rotation and longer life, especially if your machine runs many hours a day. The package also includes a digital RGB controller, allowing you to manage Addressable RGB lighting without necessarily relying on the motherboard.

• Size 140 mm – larger blade for more air at lower RPM compared to 120 mm variants.
• RPM 500–1500 – wide range for quiet mode under light load and more aggressive cooling during gaming and heavy load.
• Airflow 30.39–91.19 CFM – suitable for building an effective front intake or top exhaust in mid-tower and larger cases.
• Pressure 0.17–1.52 mmH2O – flexible solution for both free flow and scenarios with denser filters or grilles.
• Noise level 22–33 dBA – balanced profile that won't dominate over other components as sound during normal operation.
• Dynamic fluid bearing – smoother operation and better durability during long-term use.
• Addressable RGB + digital controller – flexible control over lighting even without a suitable RGB connector on the motherboard.
• 4-pin PWM connector – easy connection to the motherboard or controller for automatic control based on temperature.

Who it is suitable for

This set is suitable if you are building a gaming or RGB build and want two 140s at once – for example, for front intake or top exhaust with visual appeal and control over the lighting. It is also a good choice if you want to upgrade the stock fans of your case to quieter and more flexible ones in terms of RPM and RGB. If you are looking for an ultra-minimalist configuration with no lighting at all, the addressable RGB here might be more of an unnecessary bonus.

The most sensible aspect of this set is the combination of two 140 mm fans with PWM control, dynamic fluid bearing, and included digital RGB controller – you get cooling and visual flexibility in one, without having to deal with additional accessories.
