Wired vs Wireless Lian Li Fans
Connectivity
The Lian Li UNI Fan SL-Infinity Wireless uses a 2.4 GHz wireless signal to manage both fan speed and ARGB lighting, eliminating cable clutter entirely. It includes a redesigned receiver that connects to power both blades and LEDs via a single 4-pin cable. In contrast, the Lian Li UNI Fan SL-Infinity 120mm White 3-Pack relies on a standard wired controller setup. This means you must manage physical cables for each fan connection. If you prefer a clean build with minimal visible wires, the wireless model offers a distinct advantage by handling control signals without individual data cables running to your motherboard.
Performance Specs
The Lian Li UNI Fan SL-Infinity Wireless provides specific performance metrics: a maximum speed of 2300 RPM, airflow of 69.7 CFM for reverse blade versions, and a noise level of 32.2 dB(A). It uses fluid dynamic bearings for quiet operation. The Lian Li UNI Fan SL-Infinity 120mm White 3-Pack shares the 120mm size and fluid dynamic bearing type, but its published specifications do not list maximum RPM, airflow, or decibel ratings. Without these numbers, you cannot directly compare the cooling efficiency or noise output of the wired model against the detailed stats of the wireless version. The wireless model wins on transparency.
Lighting Control
Both fans feature ARGB lighting with fluid dynamic bearings. The Lian Li UNI Fan SL-Infinity Wireless highlights three independently controlled light zones for distinct visual effects, managed through L-Connect 3 software. The Lian Li UNI Fan SL-Infinity 120mm White 3-Pack is also an ARGB fan, but its data does not specify the number of light zones or independent control capabilities. Both models allow for aesthetic customization, but the wireless version explicitly details its multi-zone lighting structure. If you want precise control over separate lighting sections, the wireless model provides clearer specifications for that feature.
Motherboard Support
The Lian Li UNI Fan SL-Infinity Wireless features a new wireless receiver with an updated 4-pin cable, ensuring compatibility with 12V PWM motherboards. This simplifies installation by providing a standard connection point for power and control. The Lian Li UNI Fan SL-Infinity 120mm White 3-Pack uses a controller that typically connects to motherboard headers, but its specific connector type and voltage compatibility are not listed in the provided data. You can confirm the wireless model works with standard 12V PWM setups, while the wired model’s exact electrical requirements remain unspecified. The wireless option offers clearer motherboard integration details.
Blade Design
The Lian Li UNI Fan SL-Infinity Wireless is available in a reverse blade configuration, which is useful for specific airflow needs or aesthetic symmetry in certain case layouts. The Lian Li UNI Fan SL-Infinity 120mm White 3-Pack does not specify its blade direction in the provided data. Both are 120mm fans, so they fit standard mounting positions. However, if you require reverse airflow for a particular build setup, the wireless model explicitly offers this option. The wired model’s blade orientation is unknown from the available specifications, making the wireless choice more versatile for specialized airflow requirements.
Which Lian Li fan should you buy
You want total cable freedom
The wireless model uses a 2.4 GHz signal to control speed and lighting. This eliminates the need for separate ARGB and fan headers. You get clean cable management without sacrificing control via the included receiver and L-Connect 3 software.
You prefer standard wired setup
The wired version connects via a standard controller. It uses fluid dynamic bearings for quiet operation. You get reliable 120mm airflow and ARGB lighting without needing a wireless receiver. This is a straightforward choice for traditional motherboard connections.
You need reverse blade airflow
The wireless pack features reverse blades for specific cooling configurations. It delivers up to 69.7 CFM of airflow at 2300 RPM. The noise level stays low at 32.2 dB(A). This spec is unique to the wireless model in this comparison.
