Generally, they are good fans... as far as temperature is concerned, they do their job just fine.

The downside is that they make quite a bit of noise and I also had a period when 2 out of the 6 fans I installed in the computer made a strange noise, like creaking, for no reason. It fixed itself after a week.

Very good (in terms of performance) and quiet fan. Very easy to connect 2 or more fans together with one cable, which really helps with cable management. Beautiful in appearance as well (design & RGB)

Amazing fans, very efficient as well as beautiful. You need to do a bit of research on how to connect them if you use multiple with the daisy-chain logic, but overall they are very decent.

I had read various negative things about the store but you should know everything went just fine. The store shipped them very quickly. And the packaging was just fine.

Silent and very convenient to install, especially if there are more than one as they connect to each other and with one cable you can have up to 3 fans. The lighting is also very good, ideally for RGB adjustments you need L-connect but it is also compatible with open source solutions like OpenRGB.

Amazing fans, they stand out from all the others out there, very good airflow, quality, and very beautiful. In the triple pack, it comes with a hub-controller, I recommend getting it because it gives you the option for 4 slots so you can have many fans together, as long as they are Lian Li SL Infinity, including the reverse ones. So far, 4 months since purchase, very satisfied. If you also download the app, you can change the lighting and the airflow strength on each of the 4 separate ports that the controller has.

What can I say about these fans, they are very high quality with good airflow. If you also download the Lian Li app, you can play with the colors and adjust how strong the airflow will be for each one individually. A bit expensive, but they pay you back to the fullest with their appearance and performance. GPU 4070 SUPER 12GB, Motherboard MSI Mag Tomahawk B650, CPU 7600X

Silent and very beautiful fans, my favorites from Lian Li. I installed them on the water cooler from the same company (Hydroshift N) and automatically the processor temperature did not exceed 70°C, also easing the pump at the same time. With the included controller, you save on cables since each group of fans requires one cable to operate (power and ARGB). You can operate up to 4 groups of fans this way and control them completely from the L Connect 3 software, as well as the water cooler.
Their negative points are the price and the instructions that do not mention that if the cable is inserted the wrong way, they do not work.

I really have no words….perfect little fans and a very easy program to note that I didn't read the instructions at all and at first when I took the things out of the box they seemed way too many and difficult but in the end it was super easy also by the time I put them in the computer to close the box etc. I had frozen (because they were blowing on me) get them without a second thought

I will say exactly the same as the regular one. Amazing fan, good performance, perfect look, and silent. Here you pay for the look. I have been using them for 1 year and so far I have no issues. I am running 10 inside a LianLi O11D EVO XL, 6 reverse and 4 regular. I must say that as a company, Li is top-notch and something I needed for the case was promptly addressed by the parent company without me having to deal with the store of purchase.

very beautiful lanterns, their noise is normal, no issues with temperatures the only problem is the rgb which struggles if you want everything in the lian li application

overpriced.
very complicated with very little documentation online.
after many returns to stores, I bought 3x 140mm reverse blade and this pack with the 3 in 1+ controller.

I connected the fans to Arctic Liquid Freezer III RGB with the Y-cable (of the 140mm) and with the cable kit (separate purchase) I connected it to the sync port on the controller.
Lian-Li has generally done a good job, but those things are beautiful, what can you do.

Performance is very good, at 100% they make a lot of noise though.

Also, it bothers me a bit that the side RGBs do not "connect" with each other to create the lines that the SL and TL series do, but what can you say. We hope for the SL-INF v2

Do not trust all the comments you see. Look for reviews. Incredible fans. I got 3 and they connect in a row without wires, with only one at the end. Through the lian li software the rgb dances. It has mirrors on the sides and in the center and thin led strips on the edges resulting in giving it depth (infinity). In normal mode, they are not heard at all and the air pressure is more than satisfactory. By far the best fans out there. I have three below for intake and an arctic liquid freezer II on the cpu above for exhaust. With hours of gaming, the 7800x3d and the 3090 have not exceeded 60 C

Installation conveniences: Interconnection between them with interlocking mechanism without cables (up to 4 fans), detachable cables (PWM, ARGB) with a mechanism for changing direction depending on how their connection is convenient, the package of three with the integrated hub includes 4 cables with built-in PWM, ARGB in a single connection to the hub (up to 4 fan groups), the hub includes 2 inputs for separate timing of other devices with ARGB in addition to the motherboard, and also includes a Y branching of a single PWM, ARGB cable for connection and a 5th fan group.

They have unique connectivity between them, breaking and sticking with two movements. The packaging provides everything needed to operate, such as an ARGB controller. The connection requires a SATA power and a USB 2.0, which your motherboard should provide. You can manage everything through the compatible L-Connect program, otherwise, if you prefer management through the motherboard, you will need to connect an additional ARGB cable from the controller to the motherboard's 4-pin sys fan.

Okay, it makes noise when the temperature rises even momentarily, but it says so in the specs! If you don't have temperatures, it will be quiet. Without such noise, you may not have these performances with any brand in 12V. I bought it as an SP fan for the be quiet dark rock pro cooler, for its appearance alone.
As for quality, I would say it's the best there is. But okay, not 30 euros, come on.

I don't think there are more beautiful fans than the Lian Li UNI Fan SL-Infinity. They are worth their money and more

The new fans from LIAN LI are amazing and definitely worth it. They have a refreshed appearance and performance (61.3 CFM) and are quite silent, I must say.

Before using them, I was playing Call of Duty Modern Warfare/Black Ops Cold War at temperatures above 100+°C, but after installing these fans, I haven't exceeded 74°C, with the junction temperature reaching up to 90-100 °C.

I am extremely satisfied with their performance. I highly recommend them!

(The case has 3 top fans, 3 front fans, and 1 back fan, all LIAN LI SL Infinity 120mm, if it helps with the temperature in °C.)
