I installed this three pack in my desktop PC, and I was impressed by both the build quality and the overall design. The interlocking system makes cable management much cleaner than using individual fan cables, which helped simplify the entire installation. The included controller was easy to connect, and the ARGB lighting is bright, smooth, and evenly diffused without visible hot spots. It gives the system a clean, premium appearance while still allowing plenty of customization. Performance is equally impressive. The fans move a good amount of air while remaining relatively quiet during normal operation. They provided excellent airflow for my case, and I noticed stable temperatures even under heavier workloads. The frame feels solid, and the bearings operate smoothly with no unusual vibration or rattling after installation. Everything fit together well, and the overall quality is what I would expect from Lian Li. If you're building a new PC or upgrading your cooling system, these fans offer an excellent combination of performance, aesthetics, and easy installation. I would definitely recommend them to anyone looking for high-quality ARGB case fans.

Lian Li at it again with a premium product! Gorgeous dual-zone infinity lighting, and the easiest modular install in the game. These Lian Li UNI FAN SL Flex 120mm fans are excellent. I have a total of 10 fans in my PC build and I couldn’t be happier! Build quality is top-tier. The frames feel solid and and well made, the rubberized corners do a good job of damping vibration, and the fluid dynamic bearings are smooth and quiet. Everything locks together cleanly with the classic UNI Fan interlocking system, no flex, and no cheap plastic feel. LED quality and brightness is where they shine (literally). Each fan has LEDs with dual-sided infinity mirror lighting and independently controllable zones. The lighting is bright, even, and vibrant without looking washed out or uneven. The infinity effect adds real depth from the sides and front, and the dual-zone control lets you create layered looks that stand out without being over-the-top. Colors stay true, brightness is adjustable, and effects in L-Connect 3 look polished. Motherboard 5V ARGB sync also works well if you prefer that route. Installation is one of the best parts of the UNI Fan ecosystem. Snap up to four fans together with the interlocking design and you only need one set of cables (via the FLEX receiver) for the whole group. Mounting to a case or radiator is standard screw work. The FLEX receiver supports both L-Connect 3 (with L-Wireless for broader Lian Li ecosystem control) and direct motherboard PWM + 5V ARGB, so you have flexibility depending on your preference. Triple packs include the wireless controller and extra cabling. They deliver solid balanced cooling. They’re quiet enough for daily use and ramp up smoothly when needed. Not the absolute highest-pressure radiator kings in the lineup, but more than capable as case fans or on mild radiators, and the noise-to-performance balance is good. They’re on the premium side price-wise, as expected from Lian Li, and the 28 mm thickness is something to keep in mind for tight clearances. The software, L-Connect 3, works well once set up. Like most RGB ecosystems it can take a minute the first time. Overall these are some of the nicest-looking, easiest-to-install ARGB fans available right now. High build quality, excellent and bright LED’s. Highly recommended.

This 3 Pack of Lian Li UNI Fan SL Flex 120mm ARGB fans is the most technically impressive set of PC fan's I've worked with. Over the years, I've bought a lot of Noctua, Antec, and Be Quiet brand fans, all of which have served their purpose and worked well to cool my PCs. But these Lian Li fans have a bunch of really well engineered features that make them such a pleasure to use and look at. The first of these features is that the fans snap together with integrated brackets, with no tools needed. They can join into blocks of up to four fans. When they are attached to each other, the fans pass power and ARGB signals through built in spring loaded contacts from one to another, completely eliminating the need for a cable running to each fan. This alone makes them worth taking a good look at when designing a high end PC cooling setup. The second unique feature is that these fans can be fitted with the included wireless receiver, then controlled remotely via the included USB transmitter. This really cuts down on cable clutter. The only connection needed for the entire block of fans is a single power cable. If you don't want to use the wireless transmitter, a regular ARGB cable is included that attaches directly to the fans. At a mechanical level, these are listed as having a fluid dynamic bearing setup rather than sleeve bearings, so they should run well and stay quiet for a very long time. Airflow is good, and these fans run very quiet. I could not hear them in my somewhat noisy workshop up to almost their full speed of 2000RPM. The RGB lighting quality is very nice, with both front and side illumination. RGB lighting is not a huge feature to me, but it's very well done on these fans and will please users who want to set up color fades and patterns. Finally, when I pick up these fans they feel quite hefty compared to some others I've used. They seem really sturdy and well built, and are just beautifully designed. These are premium fans, and come at a premium price. In my opinion these are worth considering if you're building a top tier PC and want some extremely high quality fans with very unique features.

This is a nice triple pack of fans for your PC. Measure the area in your case to ensure the fans will fit before ordering this kit. In my case, I could only fit 2 in the front for intake air. The third fan is kept as a spare. The fans connect to each other without wires, then a control and power cable connects to the last fan and wires connect to your motherboard. I found an excellent video for setting up this kit. So easy to understand and complete in it's explanation, but I can't included a link. please search for Lian Li SL Flex detailed wiring and setup guide if you get stuck with your install. I can't really hear any additional noise coming from my PC after adding the fans. If it's louder, it's not by enough for me to notice. Fan speed is controlled by my motherboard with a single cable. If you only connect the power cable, you get a white light from the fans. I'm quite happy with this look. However, the fans are capable of so many more colors and visual effects. I'll eventually install the additional parts and software as I can tie the visual cue to boring PC performance or temps. Most importantly, temps came down for my graphics card and CPU. I'm very happy with the upgrade. Note that for this fan, the light is on the fan housing. the blades are not illuminated. It's still a stunning effect, but more subtle than an illuminated fan.

I grabbed this set of three Lian Li UNI Fan SL Flex 120mm ARGB fans to be paired with my existing Lian Li UNI Fan SL-INF LCD Flex 120mm reverse fans. The fans have a well-built and rigid feel to them without any noticeable wiggle or slop around the fan hub area. The blade design works great for getting the airflow direction I wanted while keeping the visible side looking clean in my build. These fans matched perfectly with my existing fans except these do not have LCD screens in the hub area. The installation of this kit was quick and easy, and the modular connection system makes cable management much cleaner than with traditional fans. Mounting the fans to my chassis and radiator was effortless since the screw holes on the fans matched my PC chassis. The lighting is bright, smooth, and vibrant without looking overly excessive. Performance has also been excellent, with smooth operation and strong airflow while keeping noise levels reasonable. These fans run quiet, but they are not totally silent. I’ve noticed consistent temperatures during longer gaming and multitasking sessions. Overall, these fans combine great cooling performance, customization, attractive lighting, and clean-looking installation in one package.

These are exactly what I expect from Lian Li UNI fans — great looking, well built, and much easier to install than dealing with separate cables from every single fan. The fans connect together directly, so a group of three only needs one receiver connection. That makes cable management noticeably cleaner, especially in a case with a lot of fans. The included wireless controller is another nice bonus with the 3-pack and makes setup with L-Connect pretty straightforward. The RGB looks excellent. The infinity mirror effect on the sides gives them a more premium appearance than regular ARGB fans, and the lighting is bright and smooth without looking cheap. They also move plenty of air while remaining reasonably quiet at normal speeds. My only minor complaint is that getting the most out of all the lighting and wireless features does mean relying on L-Connect. You can also connect them through standard motherboard PWM and ARGB if you prefer a simpler setup. Overall, these are excellent fans if you care about both appearance and clean cable management. They aren't the cheapest 120mm fans available, but the design and much cleaner installation make the extra cost worthwhile.
