I know this isn't the first of its kind, but it's certainly my first time with a fan that goes this far down the modular connection approach for daisy-chaining multiple fans. Keep that in mind as my thoughts are influenced by this to me novel connectivity approach, which has been further updated from Lian Li's previous fan releases in the same design philosophy. It makes for an extremely clean setup and look with multiple fans, and there are tangible quality of life improvements over the previous-generation Lian Li fans too, such as the removable interlocking keys that not only help with aesthetics but eliminate any interference with tubing and fittings on radiators. I also liked that the single cable connector on the fans can take the cable reversed in direction to help with the hidden mess downstream.

That's the downside of such an approach where you have a 7-pin connector which is proprietary for all intents and purposes going to a hub which accepts way more fans than the three it ships with. There are even two ports for Lian Li AIO cooler pumps, which is a neat way to keep you in their ecosystem. Five cables head out from the hub, where I can only hope Lian Li does a better job with a video and guide compared to the barely satisfactory paperwork that ships with the fans. Then comes the software program which can be irksome to even get to before experiencing a couple of bugs. Oh, did I mention the software was at 10–15% CPU utilization even when minimized in the system tray? There's work to be done here—this tech does not feel ready for prime time just yet.

But for those willing to try it out, the product is ultimately stable enough to do everything you'd expect. There's handy start/stop functionality for the fans which already have a long, linear range of RPM control, and multiple preset and customizable fan curves can be set in the software. Then there are 32 different lighting effects with associated options, and the ability to separately control the LEDs on the frame and hub. It could all be better implemented for sure, but I dare say you are interested in these fans for the fancy infinity mirror aesthetic which is about average in execution in my books, but this is perhaps again my inexperience with RGB-first fans speaking. I'd personally also not recommend these if wanting high performance radiator fans, but I suppose the performance-to-noise balance is good enough to where you simply just run the fans at faster speeds for cooling performance others achieve at lower RPM and similar noise output. There isn't enough polish for me to recommend these in the watercooling segment, but I appreciate the design and engineering enough to give the Lian Li UNI Fan SL-INF 120 the Innovation award.
