Lian Li would like to “set stylish new standards” with its new 120 mm and 140 mm RGB fans from the Uni Fan SL V2 series, according to the Taiwanese manufacturer as part of the presentation of the overall four fans. Among other things, these should convince with a “unique” connector system, daisy chain and ≤ 29.2 dB(A).
(A)RGB -Lighting stays within limits
Even before the technical implementation or even the specifications come into play, the four new fans of the Uni Fan SL V2 series, like their predecessors, are particularly noticeable due to their appearance, in the form of a visually rather discreetly staged (A)RGB lighting . In this case, the 32 digitally addressable LEDs are literally in the frame when they appear, as the manufacturer demonstrates in its product video.
Lian Li outlines the highlights of the new fan series, which includes four fans, the 120s and 140s of which are to be placed both in cases and on radiators, as follows.
- Improved cooling performance
- Wireless daisy chain connector system
- Control via L-Connect 3 and controller
- Sophisticated lighting effects
- Controller for up to 16 fans
- Start/stop mode
In order to draw the main attention once again to the optical components of hardware and peripherals, which are also becoming increasingly important for gamers, the manufacturer has already included the new effects in a corresponding demo in the Detail presented.
Daisy-Chain connector system saves Cable
The plug-in system, which uses a daisy chain to connect several Uni Fan SL V2 120 or 140 in series and combine them into a cluster, is intended to make it particularly easy to control several fans using just one cable. The ARGB lighting and the speed curve are configured using the in-house software L-Connect 3 and a controller for up to 16 fans.
