Amazing
Can't believe I didn't already leave a review, these are just absolutely amazing I don't mess around much with RGB software (since so much of it is clunky), but this was easy to get all 24 fans synced. I'd like more customization in the software but honestly it's barely a complaint, the fans themselves are great. The color is bright, the changes are fluid, and the infinity mirrors add so much more depth and visual detail. Best things about them? The cables. I replaced 24 fans that each had 2 cables, one for power and one for rgb control...which meant I had 4 fan and 4 RGB controllers...64 cables for just fans. With this, I've got 24 fans, 7 direct power/rgb cables, 2 fan controllers that also controller RGB, and 4 cablrs coming from those two...from 64 cables down to 11. Obviously there are other fans that can directly link to one another to cut down on cables, but man...these just look so much better in person. As for airflow, I don't have a whole lot I can speak on it because I run a push/pull configuration and rarely go beyond 1300rpm unless I'm stress testing something. It holds well at 2100 rpm under extreme load when I do push it. One thing to note, the power cables can only mount in one direction, which was a tad bit annoying for me but not a deal breaker.

Style & performance!
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!

Great looking fan
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!

Great forward or reverse fans
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.

Solid performing Fan, but better visuals is used as Exhaust
Solid Fans, I have 7 of them in my case. The reduction in cables due to the setup is worth the price alone. The only issue I have is that you lose the infinity mirror effect in the center if you use as an intake fan as its only on one side, Unfortunately I have a Lian Li Dynamic Evo case and the two three packs are used as intake, one at the bottom and one on the side. The mirror is covered up in both cases. The side mirrors are still impressive, and its only a minor gripe

very easy installation
I’ve had these in my PC for about a year now and I’m still really happy with them. I originally bought them because I wanted something that looked unique but still clean, and they ended up fitting my build perfectly. I run them in a purple-on-purple RGB setup, and the lighting looks especially good with the infinity mirror effect. One thing I really liked during setup was the daisy-chain design. It made installation a lot easier and cleaner than dealing with a bunch of separate fan cables everywhere. That alone helped the build feel more organized and less frustrating to put together. After a year, the main reason I still like them is that they really do combine looks and function well. For me, these were not just regular fans, they were a big part of the overall visual direction of my computer. If you care about aesthetics and want something that makes your build feel more custom and polished, these are definitely worth looking at.

Quality is great
Wow this fans are just very good. The build quality on these compared to the Corsairs I had before is just different in a positive way. It has rubber pads and it is sturdy. For me the best fans out there are noctua and then Lian li if you include the look factor. Also they are customable meaning you can dayay link them and change the orientation of the cables coming out of the fan
