## Description

Lian Li UNI Fan SL-Infinity 140-Single Pack-ARGB Fan-Daisy-Chain Design-Infinity Mirror-Customizable Lighting Effects-Without Controller-White-(UF-SLIN140-1W)

Review: Works well - Used as a bottom of the computer case intake fan in a Thermal Take Tower 300 (mounted just above the power supply). Chose the reverse blade version for a cleaner look inside the case that avoids showing the “ugly” side of the fan where the wires are usually crammed into narrow channels. The sides of the fan have infinity mirrors which match the RGB of the fan blades and give it a unique look. May someday replace the 3 120mm fans that came with my AIO CPU cooler with these fans, but would be mainly for the aesthetic. Quality of the fan itself is great and the customization of the cables and mounting are great options.
Review: Extraordinarily Extravagant - 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.

## Features

## Questions & Answers

**Q: Can these lian li uni sl-infinity 120 fans be used as radiator fans?**
A: I've done a ton of research on static pressure fans (what you want for coolers) and the sl-inf actually perform excellently in that regard. They are in the top 85-90% of best static pressure fans, and that is probably underselling them slightly. They are also amazing at simply moving air as case fans.

**Q: If I were to purchase two sets of these, would it be possible to use the y-splitter to power 3 front fans and 2 bottom fans with a single controller?**
A: Yes and you wont even need the splitter.Im currently running 6 fans on one controller with no splitter.

**Q: Can you control a cluster in software other than L Connect like Asus Armoury with the controller? Like fan speed for cpu is different than the rest?**
A: The 3 pack comes with a cable you can plug into the controller that plugs into a fan header and argb header of the motherboard so that you can control them through armoury create. You have to switch to "MB Control" in the L-Connect 3 software. Not sure how well the level of control would be in any other software other than L-Connect 3 though.

**Q: I am buying the 140mm fans size which don't have a connector. Is the connector in this 120mm kit compatible? How can I buy it?**
A: Connector?  That could mean so many things when talking about these, but if you're talking about the pinned connector that connects the fan to the controller or the mobo, then the answer is no, because they're different voltages, but if you actually meant the controller hub, since I can't figure out why you wouldn't have the pinned connector that comes with the fan, then the answer is yes, you can use one controller for either size.

### ⭐⭐⭐⭐⭐ Style & performance!
*by T***S on December 29, 2022*

I have been running a case full of SL120 Infinity fans for around 5 months now. Recently moved my build into a new O11D Dynamic Evo, so I was in need of an extra rear exhaust fan. These guys had one in stock when everyone else seemed to be sold out at the time - and for regular price. Best fans I have owned! Incredibly easy to install, especially if you have a L Connect Controller already. The ability to click them together in groups and use only one cable per group, makes cable management and the installation process a breeze. For reference, before I switched to these Infinity fans, I ran a whole case of Corsair fans. I went from 18 individual cables going to a controller, down to 3. Adding this extra fan only added one more cable, for a total of 4. That is amazing! As for noise, at low speeds you don't even hear them. Medium speeds they are audible, but quiet. Of course at the highest speeds they can get loud because of their very high rpm capability. But they rarely, if ever need to be that high. In terms of price to performance, they are up there with some of the best. Sure, you can get some BeQuiet or Noctua fans without RGB that can move more air, but the fact you get this kind of performance out of one of the most beautiful fans out there, is well worth the price. Long term reliability is still up in the air due to the fact they were released only about 6 months ago, but so far so good! (Knock on wood lol) Definitely recommend! Lastly, Coolerguys were completely on top of this order. The fan showed up a couple days before it was supposed to and the entire process was easy. 5 stars so far!
