Stunning hardware, impressive performance, and frustrating software flaws

If you’re building a visually focused PC, the 120mm UNI FAN TL LCD fans from Lian Li are hard to ignore. With integrated LCD screens, sleek RGB lighting, and the signature UNI FAN interlocking system, these fans are clearly designed for high-end showcase builds.

After spending real time with them, I can confidently say: the hardware is excellent. Unfortunately, the software experience holds them back from perfection.

Design & Aesthetics: Where These Fans Shine

The standout feature is obviously the 1.6-inch LCD screen built directly into the fan hub. It’s bright, crisp, and surprisingly sharp at 400×400 resolution. Whether you’re displaying CPU/GPU temps, animated system stats, or custom GIFs, the screen adds a level of personalization that most fans simply can’t touch.

Visually, these fans are exactly what you’d expect from Lian Li:

• Clean frame design

• Infinity mirror RGB accents

• Premium finish that looks intentional in both black and white builds

They’re made to be seen, and they absolutely succeed at that.

Performance & Build Quality

Despite being heavily aesthetics-focused, performance doesn’t feel like an afterthought.

Highlights:

• Smooth operation up to ~1900 RPM

• Respectable airflow for both case and radiator use

• Quiet enough on balanced fan curves

• Excellent build quality with zero “cheap” feeling parts

The UNI FAN interlocking system also makes cable management far cleaner than traditional fan setups. Fewer cables, fewer headaches, and a much more polished final build.

Software Experience: The Biggest Weak Point

This is where things start to fall apart.

❌ Frequent Disconnections from L-Connect

The fans and LCD screens randomly disconnect or stop appearing in L-Connect 3, which means:

• LCD screens freeze or stop updating

• Fan controls disappear

• RGB settings reset or become inaccessible

Sometimes a reboot fixes it. Sometimes reseating USB headers helps. Other times, it feels completely random. For a premium product, that inconsistency is frustrating.

❌ Controller Firmware Update Bricking

The most serious issue I experienced was a controller bricking during a firmware update. After updating through L-Connect, the controller became unusable and would no longer be detected.

This isn’t just inconvenient—it’s stressful, especially when firmware updates are pushed as “recommended.” For a product that relies so heavily on software, failed updates are a major concern.

Pros & Cons Summary

✅ Pros

• Gorgeous LCD screens with excellent clarity

• Premium RGB lighting and infinity mirror design

• Strong airflow and quiet performance

• UNI FAN system keeps builds clean and organized

• Perfect for showcase and themed builds

❌ Cons

• Fans and LCDs frequently disconnect from L-Connect

• Software reliability is inconsistent

• Firmware updates carry real risk

• Controller failure can leave the system unusable

Final Verdict

The Lian Li UNI FAN TL LCD 120mm fans are some of the most visually impressive fans on the market. The LCD screens are genuinely fun, the RGB is top-tier, and the physical hardware feels every bit as premium as the price suggests.

However, the experience is only as good as the software—and right now, L-Connect and firmware stability are the weak links. If Lian Li can improve software reliability, these fans would be nearly flawless.

Until then, they’re best suited for builders who:

• Value aesthetics above all else

• Don’t mind troubleshooting software

• Are comfortable being cautious with firmware updates

They’re beautiful, powerful, and innovative—but not without frustration.
