Specs and Build Comparison
Lighting Technology
Product A lists customizable lighting effects with 40 LEDs per fan, emphasizing an infinity mirror design visible from any angle. Product B explicitly identifies its lighting as ARGB. While both offer multi-layer visual effects, the specific control method differs. Product A highlights individual lighting modes for blades and frames. Product B relies on the ARGB standard for synchronization. This distinction matters if your motherboard supports specific protocols. You should check your board's compatibility with ARGB headers versus the controller included with Product A.
Bearing Type
Product B specifies a Fluid Dynamic Bearing in its key specs. Product A does not list its bearing type in the provided data. Fluid dynamic bearings are generally known for smooth operation and longevity. Without explicit data for Product A, you cannot verify if it uses the same technology. This makes Product B the clearer choice if bearing longevity is a primary concern. You may need to check the manufacturer's website for Product A's bearing details to make a full comparison.
Controller Inclusion
Product A is a Triple Pack that includes a controller capable of supporting up to 16 fans. Product B is also a 3-Pack but the data does not mention an included controller. This is a significant practical difference. Product A allows you to manage lighting and fan speed without using motherboard headers directly. Product B likely requires connection to your motherboard's ARGB and fan headers. If you lack available headers, Product A's included controller offers more flexibility for expansion.
Color Options
Product A is listed as Black. Product B is listed as White. Both offer infinity mirror aesthetics. The choice depends entirely on your case interior color scheme. Product A features a black frame and blades. Product B features a white frame and blades. This is a purely aesthetic decision. Ensure the fan color matches your other components. There is no performance difference between the black and white variants based on the provided specifications.
Radiator Compatibility
Product A highlights enhanced radiator compatibility with a removable keylock and reversible cable module. This design helps when fitting fans against tight radiator fittings. Product B does not list these specific mechanical features in its data. The reversible cable module on Product A provides practical installation benefits in tight spaces. If you are mounting fans on radiators with bulky fittings, Product A's design may simplify the build process.
Which Lian Li Fan Should You Buy
Users wanting full controller integration
Product A includes a dedicated controller that supports up to 16 fans across four groups. This expandable support allows you to manage multiple units easily. The included hardware simplifies setup for larger builds, ensuring clean cable management and organized lighting control without needing additional separate components.
Those preferring white aesthetics
Product B is available in a white color option, making it suitable for light-colored builds. It features fluid dynamic bearings for smooth operation. The ARGB lighting provides customizable effects, and the three-pack format offers a consistent look. Choose this if your case interior favors white components over black.
Builders needing radiator compatibility
Product A offers enhanced radiator compatibility through a removable keylock and reversible cable module. This design improves fitment around radiator fittings, which is critical for water cooling loops. The interlocking cable style also helps maintain a tidy setup, reducing clutter near critical cooling components in your PC case.

Frequently asked questions
Are the black and white versions of the Lian Li UNI Fan SL-Infinity 120mm identical in performance?
Yes, both versions share the same 120mm form factor. The black model, model UF-SLIN120-3B, weighs 15.9 ounces and includes a controller for up to 16 fans. The white model, model 12SL-IN-3W.00, focuses on matched lighting symmetry. You choose based on case color preference rather than airflow differences.
What is the difference in dimensions between the black and white Lian Li fan packs?
The black pack measures 2 inches in width, 2.7 inches in height, and 10 inches in length for the cable assembly. The white pack lists a width of 0.98 inches, a height of 4.81 inches, and a length of 4.72 inches. These varied measurements reflect packaging or component layout differences, not the fan blade size itself.
Does the Lian Li UNI Fan SL-Infinity 120mm Triple Pack include a hub for synchronization?
The black version includes a dedicated controller that supports up to 16 fans across four groups. This hardware simplifies setup for larger builds by managing multiple units. The white version data does not explicitly list a controller, so you may need to check compatibility with your motherboard's ARGB headers for synchronized effects.
Can I mix the black and white Lian Li fans in the same build?
You can physically mix them as they both use the standard 120mm size. However, the black pack emphasizes organized cabling and synchronized lighting via its included controller. The white pack targets visual symmetry. Mixing them might create a disjointed aesthetic unless you carefully manage the lighting control methods for each group.
How many fans come in each Lian Li UNI Fan SL-Infinity 120mm pack?
Both products are sold as triple packs, meaning you receive three fans per box. The black model is identified as a Triple Pack Black. The white model is also a 3-Pack. This allows you to fill three standard 120mm slots in your case for intake or exhaust configurations.
Is the lighting on the white Lian Li fan truly ARGB?
Yes, the white model explicitly identifies its lighting as ARGB. This allows for customizable color effects that can be controlled via motherboard software. The black model also features 40 LEDs per unit for an infinity mirror effect, but its primary selling point is the included controller for managing up to 16 fans.
