120 mm Reverse-Blade Wireless Fan

The Lian Li UNI Fan SL-Infinity Wireless is a single 120 mm case fan with a reverse-blade design and addressable RGB lighting across three independent zones. It connects through a 2.4 GHz wireless signal to a required L-Wireless controller that is sold separately. Fluid Dynamic Bearings keep the unit running quietly at speeds up to 2300 RPM. The package contains only the fan and its receiver; no controller is included.

Builders Who Want Cable-Free RGB

This fan suits builders who want synchronised wireless lighting with other Lian Li SL Wireless, TL Wireless or Strimer Wireless products and who already own or plan to buy the separate controller. It is not for buyers who need a complete kit in one box, who prefer a standard blade orientation, or who want to avoid purchasing an additional controller unit. The single pack omits the PWM splitter cable found in the triple pack.

Controller Required For Operation

The specification that decides fit is the mandatory L-Wireless controller; without it the fan and its lighting cannot function. The redesigned 4-pin PWM receiver auto-detects in BIOS and also works with UNI Fan SL Wireless and TL Wireless units. Maximum airflow reaches 67 to 69.7 CFM with a noise range of 29.2 to 32.2 dB(A) at full speed.

Questions about this item

Does the 120mm reverse-blade frame fit a standard 120mm case mount?

Yes, it uses the same 120mm mounting pattern as any standard case fan slot.

How is the fan powered and controlled without a bundled controller?

Connect the receiver's 4-pin PWM cable to a motherboard header; the receiver pairs wirelessly at 2.4 GHz with a separately sold L-Wireless controller.

When should the fluid-dynamic bearing be serviced or the fan replaced?

The bearing is sealed for life; replace the unit only if noise exceeds the rated 29.2-32.2 dB(A) or airflow drops below 67-69.7 CFM.
