Three Fans with an Interlocking Design

The pack contains three 120 mm fans that join together as a cluster using the UNI FAN interlocking arrangement. Each fan measures 120 × 122.1 × 25 mm. Check the available mounting positions and clearance before assembly, particularly around radiator end tanks, tubing and nearby case structures.

Lighting across the Fan Design

Infinity-mirror detailing and ARGB lighting add depth around the fan hubs and frame sides. Configure the supported effects through the matching controller and L-Connect 3. Choose colours and movement patterns that suit the visible parts of the build, while keeping the fan and controller connections arranged according to this specific UNI FAN family.

PWM Cooling up to 2100 RPM

The fans support operation up to 2100 RPM, with maximum airflow of 61.3 CFM and static pressure up to 2.66 mm H₂O. Set a fan response suited to the case airflow and system workload, using the compatible control arrangement for the supplied fans.

Fluid Dynamic Bearings

Fluid dynamic bearings support rotation across the operating range. The maximum acoustic rating is 29 dB(A). Secure the fan frames to their mounting positions and keep the airflow path clear, with the selected speed balancing the cooling needed by the build against the desired operating noise.

The Matching Controller Is Included

This three-pack includes the controller for its UNI FAN family. The three-pack uses its supplied 7-pin cluster cables and matching SL-INFINITY controller. Configure the supported speed and lighting functions through L-Connect 3, or use the supported motherboard synchronisation arrangement. Check controller power, USB communication and connection requirements before final cable routing.
