As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
If you want to review your cooling options, exploring lian li uni fan sl infinity alternatives helps you match case airflow to your specific layout. The Lian Li UNI Fan SL-Infinity provides standard 120mm case ventilation with a fluid dynamic bearing in a black finish. You might want something else if your build requires a different frame size, a white color scheme, or multi-fan packs. Other setups call for lighting-free designs, a 6-pole motor, or a slim 0.59-inch depth for tight clearance.
We selected these 6 alternatives because their hardware specifications overlap with the original fan. Every option on the list utilizes a 120mm form factor and a fluid dynamic bearing for chassis ventilation. At the same time, they offer distinct functional differences, including 4-pin connectors, rotational speeds up to 2000 RPM, and 66.17 CFM airflow ratings. Some models include integrated ARGB lighting with daisy-chain cabling, while others focus purely on silent operation without LEDs. Comparing these published numbers helps you identify the right airflow, clearance, and connection type for your build.
Our top pick: Lian Li UNI Fan SL-Infinity 120mm Black Fan.
Comparing Alternative 120mm Case Fans
Scythe Wonder Tornado 120 Slim Fan
The Scythe Wonder Tornado 120 Slim Fan differs from the Lian Li UNI Fan SL-Infinity by using a slim 0.59-inch profile. The Lian Li model uses a standard frame listed at 2 inches thick. Both units feature a fluid dynamic bearing and a 120mm frame. However, Scythe specifies a 2000 RPM maximum rotation speed and a 4-pin connector. You gain extra clearance in tight spaces, low-profile cases, and compact small-form-factor builds where standard fans will not fit. You give up the thicker casing of the original black unit. Pick the Scythe fan if your PC enclosure requires low-profile 15mm clearance with high 2000 RPM rotational speed.
be quiet! Silent Wings 4 120mm PWM Fan
The be quiet Silent Wings 4 120mm PWM Fan targets gaming chassis airflow with an integrated 6-pole motor. Like the Lian Li UNI Fan SL-Infinity, it uses a fluid dynamic bearing, 120mm sizing, and a black finish. The Silent Wings 4 provides a designated 10.9-ounce construction designed for high air pressure and low vibration. The original Lian Li model lists no motor pole count or vibration figures. However, the be quiet unit lists specific 1.22-inch depth and 10.9-ounce weight figures. Choose the Silent Wings 4 if you prioritize direct, high-pressure airflow and low motor vibration over standard basic chassis fans.
Thermalright 120mm White ARGB Fan 3-Pack

The Lian Li fan provides no published CFM data, no daisy-chain specifics, and no lighting hardware. You give up the original model's standalone single-fan packaging. Select this Thermalright model if you need three coordinated ARGB fans with daisy-chain cabling to ventilate your case using unified motherboard lighting controls.
Thermalright 120mm PWM Case Fan
The Thermalright 120mm PWM Case Fan focuses entirely on unlit cooling performance. Both this model and the Lian Li UNI Fan SL-Infinity share a 120mm size, fluid dynamic bearing technology, and an unlit black frame. However, the Thermalright TL-C12C lists an explicit 66.17 CFM airflow rating, a 4-pin PWM connector, and a light 3.53-ounce weight. The Lian Li fan omits published airflow metrics and connector specifications. You give up the original Lian Li model design. Choose this Thermalright PWM fan if you want a straightforward, unlit black cooling fan with a verified 66.17 CFM rating and standard 4-pin speed control for case intake or exhaust duties.
Thermalright 120mm ARGB PWM Fan
