This particular fan solved a problem for me that until now I was patching with various software and a constant indicator on my screen, that's why the 4 stars and ONLY for that reason.
I wanted to be able to monitor the temperature of my workstation live without having to have annoying indicators on my screen.
So I chose to add it with a 3D printed bracket on top of the DEEPCOOL ASSASSIN IV cooler so I could see the screen.
So far so good.
But here is where some negatives, in my opinion, start.
I could write whole paragraphs about how its maximum noise is NOT 29.5db, how it is extremely bulky for a 120mm, how its build quality is simply tragic, and how without a limiter it resonates and makes even more noise, but I will settle for the following:

If you are looking for a silent fan, this is NOT for you.
If you are looking for a quality fan, this is NOT for you.
If you want it for a very specific use like I did, then weigh if the price and disadvantages are worth it for you.

If you want it for the bling bling and show-off without any notable performance, it's just fine.

I will start by saying that if you want the best fans for your system, look no further; this is my personal and honest opinion.

So let's go. The Lian Li Uni Fan SL Wireless LCD are perhaps, if not the best, definitely among the best that someone can buy in the years 2024 - 2025. They cost, but believe me, they are worth every single euro! What impresses me is their sleek design. The fans have a minimalist yet premium look that fits any modern build. Their biggest "asset" is the LCD screen on the hub of each fan. You can customize what it displays – temperatures, custom animations, or even your logo. The level of customization is impressive and makes your system truly unique.

It's also reasonable for someone to wonder what happens with the screen if you want the fan to intake air into the case. These specific fans are also sold with reverse blades, which means they can intake air.

The build quality is also top-notch. The modular wireless daisy-chaining connection simplifies cable management. Honestly, the absence of cables between the fans is a lifesaver. There is none of the chaos we usually see in builds with RGB fans.

Installation is super easy. They snap together like "lego" and only require one connection to the included controller. The controller is quite small and user-friendly, allowing you to manage up to 16 fans simultaneously. This significantly reduces the number of cables and makes cable management much more pleasant.

Although appearance is one of their major advantages, cooling performance is not lacking. In a case like the Lian Li Vizion Compact, they keep system temperatures very low, even under heavy use. The fans range from 250 to 2000 RPM (depending on the model), offering excellent flexibility between silent operation and high performance.

One of the biggest aspects that photos cannot show you is the noise. However, the Uni Fan SL Wireless LCD have quite low acoustics. Even at high speeds, the noise is minimal. In idle or light use, they are almost silent – ideal for anyone wanting a quiet working or gaming environment.

The RGB is top-notch. Through the L-Connect 3 software, you can fully customize the lighting effects, speed, and of course, the LCD screen. The software is quite user-friendly, with many options and presets for those who don't want to deal with details.

However, the LCD screen on each fan steals the show. The ability to add your own logo or animations and even the telemetry of your system is simply unmatched. The price is undoubtedly high, especially when you consider that you need more than three fans in most setups now. Their triple pack along with the controller starts from 140 to 150 euros, depending on the store you choose. However, when accompanied by the trifecta of success—quality, appearance, and innovation with high performance—the cost is justified. It is undeniably a premium choice, and it shows.

The Lian Li Uni Fan SL Wireless LCD are the best fans I have had in my hands so far. They offer excellent cooling, top-notch appearance, and outstanding functionality. If you are looking for a combination of performance and aesthetics and can invest in the budget they require, it is truly a no-brainer!
