Review: 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.
Review: 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.

## Features

- An all-around infinity mirror design creates a multi-layer effect visible from any angle emphasizing the 40 LEDs in each fan.
- The use of one cable to connect up to 4 fans in a cluster and pin-to-pad contact point ensures simple cable management.
- Featuring a 10% performance optimization the result is increased airflow, higher static pressure, and a larger range of fan speed at lower noise levels.
- 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

## 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.

### ⭐⭐⭐⭐⭐ I absolutely love these fans
*by J***. on September 12, 2024*

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.
