Overview

The Razer Kunai Hydraulic 120MM aRGB fan bundle is a comprehensive cooling and lighting upgrade for PC builders who want both performance and aesthetics. Each of the three included 120mm fans features hydraulic bearings — a design choice that minimizes friction and vibration for noticeably quieter operation compared to conventional sleeve or ball-bearing alternatives. The fan blade geometry is engineered for high airflow, helping maintain optimal temperatures across your chassis even under sustained workloads.

What sets this bundle apart is the included controller hardware. The PWM fan controller lets you daisy-chain and independently manage up to eight Kunai fans, with custom fan curve profiles created through Razer Synapse software — including a zero-RPM mode for complete silence at idle. The Chroma Addressable RGB controller adds six aRGB headers, each supporting up to 80 LEDs, turning it into a centralized lighting hub for your entire build. With access to 16.8 million colors, dynamic patterns, and game-reactive effects through the Razer Chroma ecosystem, these fans deliver a level of visual customization that extends well beyond simple static lighting. The bundle provides everything needed to get started — fans, controllers, and cabling — so installation is straightforward for anyone comfortable building a PC.

Frequently Asked Questions

How many fans are included in this bundle?

This bundle includes three Razer Kunai Hydraulic 120MM aRGB fans, along with a PWM fan controller and a Chroma Addressable RGB controller for managing speed and lighting.

How many fans can the included controllers support?

The PWM controller supports daisy-chaining up to eight Razer Kunai fans, so you can expand beyond the three included fans using the same controller setup.

Can these fans run at zero RPM for silent operation?

Yes. Through Razer Synapse software, you can create custom fan curve profiles that include a zero-RPM mode, allowing the fans to stop completely when system temperatures are low enough.

What type of bearings do these fans use?

The Kunai fans use hydraulic bearings, which provide quieter operation and longer lifespan compared to standard sleeve bearings by reducing friction and vibration.

How many aRGB devices can the included RGB controller handle?

The Chroma aRGB controller has six addressable RGB headers, each supporting up to 80 LEDs, so it can serve as a central hub for multiple ARGB-compatible devices beyond just the fans.
