Expensive but fantastic fans for your build!
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.

Love these fans
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.

I absolutely love these fans
I saw these in a post about a new build and just had to have them in my next build. I added 10 fans total, including the ones that came with my Galahad II AIO. They aren't cheap by any means but they operate perfectly. Simple to daisy chain together and hook up to the controller (included with the AIO) and the RGB is super easy to control via the L-Connect 3 software. The color shift is smooth, and the infinity mirror design is sleek. My only complaint is that when you daisy chain three fans together and install them in a case that doesn't have adjustable mounting holes, you cannot put a screw in every hole as they won't line up across all three. The bottom of my case is like this, but the vertical side mount has adjustable holes so it wasn't a problem there. That is more an issue with the case I suppose but just be aware that if you want these fans, make sure the area you are mounting them in has adjustable holes for the fan screws.

Reverse fan blades for a consistent look
Given the number of cases that now have requirements for visible side intake fans, the 120 mm infinity fans with reverse blades are a must if you want to use Lian Li infinity mirror fans and keep a consistent look within your case. I also got these since I wanted to fit 3 120 mm fans on the side of a Hyte Y60 case, and these are low profile enough to fit since you can interconnect 3 of them and use a 120 mm mod kit to install all 3. One clarification in the Amazon/Lian Li description of the product: "Compatible with Lian Li SL-INFINITY 120 3 Pack only" as that made me purchase the 3 pack of SL-INF fans too, which I now have to return. I was also installing the Lian Li GA II Trinity SL-INF 360 AIO cooler, and that comes with a Lian Li controller that is compatible with the reverse blade fans too, I guess because it includes the 3 pack of SL-INF fans. Minor detail, but I suspect there are other Lian Li kits that may come with a compatible controller as well.

The goat fans
Many cheap knock offs out there, stick with these bad boys, were the few extra bucks you'll pay over the cheaply made ones.

GRAN PRODUCTO
La calidad de los ventiladores es otro mundo! Otro nivel, mueven muy buen flujo de aire, el RGB es excepcional!, el efecto de espejo infinito les da un toque único, y que puedas ponerlos en cadena de margaritas es un toque perfecto para la gestión de cables!!! El detalle de incluir protectores (micas) para que los costados no se rayen con la limpieza y no se empolven los costados es muy bueno!! Estoy fascinado, muy buen producto de Lian Li

LIAN LI UNIFAN SL-INF 140 ARGB - Ventilateur 140mm
Montés en remplacement des ventilos d'origine sur un AIO ARTIC FREEZER III 280: Le jour et la nuit en terme de performances, bruit et bien sûr éclairage ! Profitez-en pendant qu'il en reste encore... ... certes un peu cher mais plutôt l'acheter directement au lieu d'en essayer d'autres pour finalement arriver à celui-ci ;) Idéal également pour rafraichir votre boitier car très efficace et pratiquement aucun bruit jusqu'à 70% !!! Je recommande vivement.
