Style: SLIN120 Single Pack White
The Lian Li UNI Fan SL-Infinity 120 with its daisy-chaining system is a dream—just snap the fans together, and you’re left with way fewer wires to manage, providing a build that looks cleaner and is way easier to work with. The infinity mirror ARGB lighting adds a premium touch without being over-the-top, and the build quality is solid. Performance-wise, these fans run quiet even at high speeds, which is impressive considering they can push a lot of air. A bit pricey per fan, but the convenience, clean look, and endorsement from IT folk make it totally worth the extra cost.

These fans are amazing, I love the way they look and the software is super easy to use. They aren't too loud and they move quite a bit of air. I would buy again!

Now, you shouldn't buy this fan if you're trying to keep some more cash in your wallet, because for around $30 this isn't the cheapest PC fan out there. But, if you want a gorgeous looking fan inside your PC to level up its' aesthetics (and don't really care about its' price tag) this is a great fan for you! This is an 120 mm fan that is my rear fan in my PC. The RGB and the infinity mirror looks so good! It fit great in my PC and it took me no time to install this. It functions just as how good it looks!

The media could not be loaded. Colors are very fluid, looks great our of the box, cable management with these is a breeze when multiples are daisy chained. Setup in the Connect 3 app is easy but alot of options. I have a mix of reverse blade and normal for a seemless look. If you are wondering if you need the controller that comes with a set of fans, the answer is yes. The cable that comes with a single unit have two wires from each set of fans for PWM and D-RGB and the cable with the sets only have one cable to the controller, then one PWM and one D-RBG cable goes from the controller to the mobo.

The fans look fantastic and are very quiet even at high speeds. I have the three on top with the controller, then 3 more for the CPU cooler radiator, two on the bottom, and one on the back. At normal temperatures, I hardly hear the fans at all. The GPU fans are much louder. Love how the fans connect to each other. Made cable management so much easier.

The media could not be loaded. Best value for money in the PC fan realm. Highly recommend Lian Li. Bought 9 of these for me and then 9 more for my wife. They are beautiful, move a ton of air and are virtually silent. The fan speeds are fully adjustable and offer minimal to high adjustment to fit your cooling needs. They are very well built. Ive had these for more than a year now and have zero trouble whatsoever. The highly intuitive connection system minimizes ugly wires and makes you wonder why this isnt the standard for PC cooling. It will be. Well done Lian Li

The Lian Li Uni Fans are truly some of the best on the market. Offering great aesthetics, performance, ease of use and simplicity. They’re relatively low noise, well insulated from vibrations due to the rubber end pieces and built with a durable premium design. What makes the Uni fans so special is their ability to daisy chain them together a feat which Lian Li was first to do. So instead of having multiple connectors for every fan they interlock into groups with a maximum of four per group and then connect to a single connection. These reverse fans are especially thoughtful because they allow you to have the front of the fan present in your build which makes things look more appealing than the looking at the back of the fan allowing you to have your build be a bit more flashy or a show piece. In my personal build here I used 6 reverse fans three at the side intake and 3 and the bottom intake. These fans are great for first time builders and pros alike. I rated 4 stars because no 3 pack of the reverse fans means you have to purchase as many as needed individually which can be pricey and to manage the RGB and fan speeds you have to use L-connect as despite these having a normal 4-pin pwm connector and aRGB connector my motherboard can not control them and only L-connect works. UPDATE: Found a solution to the L-connect issue. If your motherboard has enough ARGB connectors don’t bother with the L-connect controller just go third party with someone like NZXT. You can then control the fan speed with CAM or desired software and use something like OpenRGB or your motherboard RGB software to control the lighting. It’s vastly superior and I recommend staying away from L-connect at all costs it’s just awful software.
