Features

  • Improved daisy chain design to connect 2 clusters of fans.
  • SL120 V2 fan frame thickness is 28mm to provide 10% improved airflow compared to V1.
  • Removable interlocking keys to provide better radiator clearance.
  • Start/stop fan RPM support for a quieter environment.
  • Smoother side lighting for a better aesthetic.
  • Only one cable is required for each fan cluster when using the provided new UNI HUB to control lighting effects via L-Connect 3.

Description

UNI FAN SL V2 revised its interlocking style to connect up to 6 fans in two clusters to a single controller port, making cable management simpler. With the new 18 cm extension cable, the ability to bridge two clusters of fans to create a 3+3 daisy-chained cluster is offered. These 6 fans can then be connected to a single port on the SL V2 UNI HUB controller. The new daisy- chaining solution reduces the number of cables needing to be managed at the back of the case and enables new lighting effects which can be continuous between the two bridged clusters. The cable module is designed to plug in and sit flush with the fan frame, which doesn’t require extra space for the module and reduces clearance issues with radiator fittings.

    • Colorful!
I enjoy looking over at my tower and seeing the colors ever so radiant. It's flashy but the quality is great as well. I recently updated my tower so I had to ensure everything new was able to fit and so far I've have no issues.

    • Easy to install and it’s not noisy
The media could not be loaded. It’s beautiful, easy to install, its quiet, and it increased cpu temps by 7 degrees celsius. It has an easy user interface to control rgb lights. It’s a perfect aesthetic with the lian li pc case. Highly recommended!

    • Simpler installation and better performance than ANY PC fan I've used.
The daisy chain function/connections of these fans make installation so much cleaner and simpler than competing fans. Their L-Connect-3 software is simple, and very intuitive. Perfect scores across the board for me. Ordered a second set when building my brothers PC.

They're so smooth and clean! Wish it was easier to take apart and clean the fan blades but hey cant complain much after a year of non stop working and the fans still are clean!

Easy set up, minimal cables, great software, fans move a lot of air and are pretty quiet. Get them.

Since I got a Lian Li case, I decided to go with Lin Li fans and was super satisfied with how easy the daisy chain functions. The fan performance is above average but isn't A+ like Noctua level. Overall, my case airflow and temps are great. I have the 120 mm fans at the tops of my case as pictured. I put 140s in the bottom. Note, if you have the Lancool 216 case, a 140 SL V2 will not fit as the rear exhaust, you will need a 120 mm there if you want a case full of SL V2 fans. The RGB on these fans are gorgeous, but they don't do white so well. It's a cool white with a very slight blue tone to it. I don't care for the controller although the L3 Connect software is fantastic. Ultimately, I decided to wire the fans and rgb directly to the motherboard and skip the controller. Otherwise, the operating system has to load before it remembers your rgb settings. I'd rather control all the rgb from the motherboard itself and have it remember my settings from the moment I turn on the PC. ... show more
