Top Amazon Reviews

🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.


The Lian Li fans have received positive reviews mainly for their aesthetic appeal and easy installation. Most users seem to appreciate their quality build, reduced cable clutter, and the included hub for fan connectivity. However, there is clear dissatisfaction with the controller and RGB lighting configuration, especially related to third-party software compatibility.

Pros

  • 👍 Fans have received praise for their great look and seamless design.
  • 👌 Reduced cable clutter and the inclusion of a hub for fan connectivity adds to user convenience.
  • 🔧 Easy to set up and install, even for first-time PC builders.

Cons

  • 🙁 The controller has been critiqued for its poor quality and struggles with third-party software compatibility.
  • 🔆 The brightness of the fans is not as high as some users might prefer.

Should I Buy It?

If you seek aesthetic appeal and reduced cable clutter, the Lian Li fans could be a worthy addition to your PC setup. However, if RGB customization and brightness are a priority, be mindful of the mentioned shortcomings. The controller seems to require improvement, so be prepared for possible compromises in this regard.


  • These fans are easy to snap together, easy to install, and look fantastic. 10/10
Built a system with these fans and it came out fantastic. The edge infinity mirrors (which are lit), the led lines around the fans, and the fans themselves just have a pretty amazing look, and the L Connect 3 software has a vast number of patterns and effects you can set up. I noticed also that the fans retain their last lighting pattern when you reset the computer, which is a nice bonus. I threw in some Strimmer cable lights because, hey what the heck. Why not? And the case was an RGB 011 so the fan lights and the case lights were nicely synchronized (did have to figure out that I had to press the case light "mode" button for 3 seconds to set it to LConnect 3 mode). Gotta say after this experience my go to company is going to be Lian-Li. Really great experience and their stuff just worked great and looked terrific. ... show more

  • Great Fans, Quiet
Great fans, quiet. The RGB function works great. It was a bit of a challenge to find proper guidance to setup all of my case fans with the controller. Just plug in the USB connector to the motherboard. Do Not plug in the motherboard sync cable. Lian Li's software works great to control the RGB function of all of the fans. These fans really dress up my new computer and case. ... show more

  • Amazing, and you’ll pay for it
Gorgeous fans. Incredibly easy to install and amazingly accurate colors. Definitely a splurge item, not good for a budget build as they are basically the most expensive fans on the market but if you’ve got the money, they’re a great buy.

  • THE BEST RGB FANS AT THE MOMENT
The best rgb fans at the moment, Lian Li nail it with the design of these fans and the connectivity, you can use 3 fans with the daisy chain and only 1 cable connected to the hub, they also send you a splitter, the hub can has 4 inputs so 4 inputs of 3 fans but also you got a splitter and thats the 5th input so 15 fans with only 5 cables is amazing for cable management. The price is a little bit high but its worth if you want the best rgb fans. Also you can connect the hub to your motherboard and control the rgb with your motherboard and keep your components in sync. ... show more

  • Modular and Stylish
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 fans look incredibly stylish while offering great functionality for a showcase build, In my personal build here I used 3 regular Uni fans and 6 reverse Uni Fans. These fans are great for first time builders and pros alike. I rated 4 stars because the 3 pack doesn’t include the non-L-connect control box connector meaning if you wanted to just plug directly into your motherboard you can’t or you need as many individual fans as you’d need connectors and those include a standard 4-pin PWM connector and aRGB connector and to manage the RGB and fan speeds you have to use L-connect as despite the L-connect control box 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. Don’t buy the 3 pack as you’ll be forced to use the L-connect contrlller and L-Connect software. Instead go with the individual fans you’ll pay the same price for 3 but the universal connector will split out into a standard PWM 4-pin and an ARGB connector. Then If your motherboard has enough ARGB connectors just go third party with someone like a NZXT fan/RGB controller. 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. ... show more
