About NZXT RGB & Fan Controller

Physically, the NZXT RGB & Fan Controller is compact and unobtrusive: with dimensions of 100 mm by 70 mm by 16 mm, it can easily tuck into many areas inside a PC case, whether behind the motherboard tray, on a PSU shroud, or tucked beside a 2.5″ drive bay.

The NZXT RGB & Fan Controller is lightweight and comes with mounting options that include magnets, adhesive strips (Velcro), or traditional mounting screws for 2.5″ bays — giving flexibility depending on your case layout and preference.

Functionally, the controller is powerful and versatile.

NZXT Black RGB & Fan Controller offers three fan channels, each supporting either 3-pin DC or 4-pin PWM fans — and with the included splitter cables, you can manage up to nine fans simultaneously.

This makes it ideal for builds with multiple case fans, radiator fans, or a mix of airflow and exhaust configurations.

On the RGB side, it provides six independent lighting channels, each able to power up to 40 LEDs, with a total capacity of 120 LEDs across all channels.

That’s plenty of headroom for LED strips, RGB fans, under-glow strips, or other RGB accessories — which is especially valuable for users building visually striking rigs.

Power is supplied via a SATA connection for the controller, while data/control comes through an internal USB 2.0 header that connects to your motherboard.

Once connected, the NZXT 3 Fan Black Channel works in tandem with software (for instance, the official NZXT CAM tool) to give you full control over fan speeds, lighting effects, and more.

Whether you want quiet “zero-RPM” operation at idle, synchronized RGB effects, or dynamic fan curves that respond to temperature changes, this controller gives you those options — bringing granular control to system performance and visuals alike.

Inside the package, you get everything needed for installation: the controller unit itself, fan splitter cables (to expand fan connectivity), and mounting accessories (Velcro/magnets).

This makes the controller a ready-to-use solution for both new PC builds and upgrades to existing rigs.

Rather than buying separate fan hubs and RGB controllers — or struggling with numerous headers — this single device simplifies things considerably.

Beyond convenience, the controller’s ability to manage many fans and RGB devices helps with cable management and internal airflow cleanliness.

By routing multiple fans and lights through one hub, you avoid cluttered cables running across the motherboard or case interior.

That’s especially helpful in builds where aesthetics matter — transparent side panels, RGB synchronization, neat interior architecture — or in compact cases where space is at a premium.

There are some limitations to be aware of.

Because the controller uses NZXT’s own ecosystem and connectors, mixing third-party RGB fans or accessories may lead to compatibility issues — the best results are obtained when using RGB fans and lights from the same ecosystem.

Also, the fan channels and splitter usage means load per channel must be monitored to avoid overloading the controller.

Overall, the NZXT RGB & Fan Controller stands out as a well-designed, user-friendly hub that brings together fan management and RGB lighting under a single, software-driven interface.

For gamers, PC enthusiasts, or anyone building a clean, high-performance PC with multiple fans and RGB components, it offers convenience, flexibility, and a good balance between functionality and simplicity.

It’s especially useful for mid-tower or full-tower cases with multiple fans and for builders who value neat cable management and synchronized aesthetics.
