Style: SLIN120 Triple Pack White with Controller
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.

Amazing looking fans that are quite and well built. I love the aesthetic of the fan and the options to adjust how they look and what color they run at thru the lian li program is top notch. Have owned for several months and no issues they work amazing will only be using lian li products from now on when I can!

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!

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.

I love the look and quality of the SL infinity fans. I had to replace the two 140mm fans on my Lian Li CPU AIO cooler due to bearing failure and went with these to match 3 other SL fans in my case. I love how they connect without a cable to each other but wish they had a better cable to plug into the SL controller. Luckily I had a cable that worked that came with the controller. The customization and the looks of these fans are really amazing.

beautiful fans, looks so nice in a white or even white and black build. daisychain feature is so good cause i don’t need multiple cables for each fans like corsairs. the rgb software is meh but better than corsairs for sure. only comparing to corsair cause i’m upgrading from them.

I love these 140mm fans, the infinity effect on them is an awesome touch to any build. I was really surprised at how quiet the fans are at all times while maintaining excellent airflow and performance. I'm using a HAVN HS 420 Case, 5090 Founder Edition GPU, and 9950x3D AMD CPU in this build and idle temps sit around 40c and 35c respectively with max pushes to 65c and 70c under heavy load, all in a fairly warm environment. Fair note to anyone buying the 140mm here, you'll likely want a controller and since that isn't included in the single packs, you'll need to buy it separately, but you can find a 120mm controller for the UNI SL-Infinity and it'll work perfectly for the 140mm versions. That said, functionality and connectivity of the fans were perfect off the start and were really just plug and go. Brightness is also great, but while on that note, for anyone looking for a white color on the rgb, these fans will not give you a pure bright white effect, if set to a traditional white on your software such as #ffffff, they will show up bluish, though using a red tint can bring you closer to a white, it will still be dimmer.
