SpecPicks Verdict

SpecPicks scored Lian Li UNI Fan SL-Infinity 140-Single Pack-ARGB Fan-Infinity… using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. Lian Li's cooling & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for cooling & fans of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Key Features

  • An all-around infinity mirror design creates a multi-layer effect visible from any angle emphasizing the 40 LEDs in each fan.
  • The use of one cable to connect up to 4 fans in a cluster and pin-to-pad contact point ensures simple cable management.
  • Featuring a 10% performance optimization the result is increased airflow, higher static pressure, and a larger range of fan speed at lower noise levels.
  • The removable keylock and reversible cable module allows for improved compatibility with radiator fittings.
  • The fan blades and the fan frame inner edges can be customized with individual lighting modes or choose from the pre-set combined lighting effects options.
