Features
- An all-around infinity mirror design creates a multi-layer effect visible from any angle emphasizing the 40 LEDs in each fan.
- When installed as an intake fan with the reverse blade this increases the airflow and lowers the wind noise.
- The use of one cable to connect up to 4 fans in a cluster and pin-to-pad contact point ensures simple cable management.
- The removable keylock and reversible cable module allows for improved compatibility with radiator fittings.
- The fan blades and the fan frame inner edges can be customized with individual lighting modes or choose from the pre-set combined lighting effects options. Embedded magnetic Fluid Dynamic Bearing provides stability, durability, and longevity.
- Features a start/ stop mode to completely stop the fan when the CPU or GPU is running below the system's set temperature.

The media could not be loaded. Love the colors. They are quiet. Quality is top notch, they cool really good and work as intended. Love the reflective infinity look on them as well. Have lasted a long time without issues.

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. I had the older SL120s installed previously before these were released since the Lian Li Galahad AIO came with them so I ordered 3 more to fill up the case. My rear exhaust fan started dying so I decided to replace all of them with the infinity fans. As far as performance specs go, the numbers are out there for your own viewing pleasure if you want to get into specifics but I won't bother doing so. There are many fans out there that would be better bang for your buck if you wanted pure performance. While these are no slouch in the cooling department, the main reason you're even thinking of buying these is how nice they look and how easy they are to install. Looks are great, as expected from the amount of visuals they crammed into 1 fan. If you're not wanting the gaudiness of it then you have the option of turning off lights or choosing the SL120s or something to keep the ease of daisychain. The fans themselves come packaged with peel off covers over all mirrored sections to protect them during shipping. The connection/daisychain method is just as easy as the SL120 though in a different location on the fan(centered instead of to the side). The fan hubs for these are NOT the same as the ones for the SL120 so if you're replacing those in your system you will have to remove the old hubs to install the ones that come with the infinity fans. In a fresh build this isn't a problem but if caught unaware, replacing these in an older build may take more time than anticipated. The fan hub also requires 2 15pin SATA connections so make sure you have the space for it. These are definitely not a mandatory item for your build as the main appeal is aesthetics but it is nice that they also do not skimp on performance. The price tag is also fairly substantial; you could buy other fans that perform the same for less money but I knew what I was getting into before purchase. Overall I'd give it more like a 4.5/5 but that's really only because I wish the Lconnect3 software had more LED pattern options.

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.

Stand out in my build. Opted for buying the three pack the first time and liked them enough to fill my case with them. Love having to use less cables with their daisy chain functionality. Love the lighting, cooling and airflow it provides for my case.

Great fans, quiet. I needed a combination of forward and reverse fans for my case. These fans provided both options. The RGB function and their software work great as well. Easy to use and easy to configure. Their controller works good as well, allows you to plug in four groups. Just plug in the USB cable to the motherboard. You do not need to sync to the motherboard.

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.

Have a bunch of these fans (3x on AIO rad, 3x on bottom of case, and 1x exhaust) + 3x Lian Li's TCL LCD fans + 2x strimmers. The fans themselves are excellent and work solo or in a daisy-chained group (which is the primary feature of these fans - they fact they snap together without need for additional wires). They look fantastic, especially when they're lit up - the infinity mirror center is awesome. The ecosystem though is a bit frustrating to get set up and working together. Single fans come with different connectors than the daisy-chained 3 packs. Everything needs to be hooked to Lian Li controllers that only come with the 3-packs. Controllers can't be daisy chained and each type of fan (SL INF - these ones - TCL and the UNF/AIO fans) need their own separate controller - which means your USB bus is too flooded with nested connections and you need to use a separate USB cable routed through the back of your case to your motherboard's I/O instead of using USB headers (which you likely don't have enough of). Lian Li sells a power supply that helps solve this issue, but it's also an issue they've unnecessarily created. Overall, great fans.. but the ecosystem took forever to set up (actually get working flawlessly), requires too many cables and controller boxes, and requires a workaround of routing a cable outside your case). The software also isn't the greatest. I'd do it all again, simply because you only have to do it once per PC build - which should be once every 4-6 years. However, there's no doubt Lian Li has complicated what should have been a simpler solution.
