Good fit for
You should consider this triple pack if you want a clean, organized setup with strong visual impact. The interlocking cable management simplifies wiring for multiple units. The included controller makes it easy to manage up to 16 fans in groups of four. The reversible cable module and removable keylock help fit tight spaces around radiator fittings.

Who should skip it
You might look at another option if you need a single fan rather than a triple pack. The data lists single pack variations, but this specific listing is a bundle. You may also skip this if you require 140mm fans, as this model is strictly 120mm. The controller supports SM-type connecting devices, but if you need a different control interface not mentioned, this may not fit. Additionally, if you prefer white aesthetics, this black version is not the right choice.
Verdict: This triple pack offers a practical solution for users wanting synchronized, high-impact lighting in a standard 120mm form factor. The included controller and cable management features make it a solid choice for organized builds.
Key specs for this fan pack
Fan Size: 120mm
This dimension defines the physical footprint of the fan blades and frame. You will need a case with 120mm mounting holes to install these units. It is the standard size for many mid-tower cases. If your case only supports 140mm fans, this product will not fit. Always check your case specifications before purchasing to ensure compatibility with your existing chassis layout.
Color: Black
This indicates the primary finish of the fan frame and blades. A black finish helps these fans blend into dark internal chassis environments. It creates a uniform look when paired with black components. If you prefer a lighter aesthetic, you might look for white variations. The color choice affects how visible the lighting effects appear against the surrounding case structure.
Model: UF-SLIN120-3B
This alphanumeric code identifies the specific product variant. You can use this model number to find exact replacement parts or verify compatibility with controllers. It distinguishes this triple pack from single packs or different sizes. When comparing options, this code ensures you are looking at the correct item. It helps you locate the right manual or support documentation for your specific hardware setup.
Weight: 15.9 ounces
This figure represents the total mass of the triple pack unit. Heavier fans may transmit more vibration if not mounted properly. You should ensure your case mounts are secure to handle this weight. It also affects shipping costs if you order directly. Compare this weight with other packs to gauge build quality. A heavier unit often suggests more substantial materials in the frame construction.
Build Quality and Physical Layout
According to the listing, the Lian Li UNI Fan SL-Infinity 120mm Triple Pack measures 2.7 inches in height and 2 inches in width. The total length, including cables, is 10 inches. The entire package weighs 15.9 ounces. These dimensions confirm the standard 120mm form factor, meaning you need a case with compatible mounting holes. The 2.7-inch height allows installation in most standard mid-tower chassis without interference from nearby components.
The design features an interlocking cable management system. This layout simplifies routing for a cleaner setup. The controller supports up to 16 fans across four groups. You can also connect two SM-type devices. This expandability suits users building larger rigs with extensive lighting needs. The included controller manages the 40 LEDs per fan, enabling customizable effects on both blades and frame edges.
Enhanced radiator compatibility is a key feature. The removable keylock and reversible cable module improve fitment around radiator fittings. This flexibility matters when space is tight. The black finish and infinity mirror design emphasize aesthetics from any angle. You get a uniform look across all fans in the pack. The physical build prioritizes both visual impact and practical installation ease for your specific case layout.
Setup And Controller Use
The triple pack includes a dedicated controller to manage the fans and lighting. This controller supports up to sixteen fans in total. You can group four fans together for synchronized control. The system also allows for two SM-type connecting devices. This expandable design helps you scale your setup without needing separate hubs for every group.
Cable management is handled through an interlocking style. This feature keeps wires organized and reduces clutter inside your case. The cables are part of the 10-inch length listed in the specs. This length provides enough slack for standard routing but keeps the rear tidy.
Installation on radiators is simplified by a removable keylock and reversible cable module. You can adjust the cable direction to fit around fittings. This flexibility is useful when space is tight near pump blocks or reservoirs. The design ensures the cables do not obstruct airflow or other components.
Daily use involves selecting lighting effects via the controller. You can customize the fan blades and inner frame edges individually. There are pre-set combined effects available for quick changes. The 40 LEDs per fan create a multi-layer infinity mirror look. This effect remains visible from any angle. The controller lets you switch between static colors and dynamic patterns. You do not need additional software if you prefer physical controls. The setup remains stable once the cables are interlocked. The controller handles the power and signal distribution for all connected units in your chosen groups.
Before You Buy This Fan Pack
You need to verify your case supports 120mm mounts before ordering. The listing notes enhanced radiator compatibility via removable keylocks and reversible cables. Check your cooler fittings to ensure they do not block these adjustments. The included controller handles up to sixteen fans. You can group four fans per group for synchronized control. This allows expansion beyond the triple pack. You may need additional SM-type connecting devices for larger builds. Keep the interlocking cable management in mind for clean routing. The infinity mirror design requires clear sightlines to show its multi-layer effect. If your case has solid panels, the lighting impact will be reduced. Consider the black color against your interior theme. This pack suits users prioritizing aesthetics and modular control. It fits well with other Lian Li products in the ecosystem. Verify your power supply headers match the controller requirements. Regular dust cleaning maintains the LED clarity and airflow performance.
Check before you buy
- Confirm your case has 120mm mounting holes for installation.
- Check if radiator fittings allow for reversible cable modules.
- Verify power supply headers match the controller needs.
- Ensure case panels allow clear visibility of lighting effects.
