Lian Li UNI Fan SL-INF 120 RGB Review: Stunning but Flawed
A Reddit user summed it up best: “I swear I spend like 10 minutes every day just staring at my PC because everything is so pretty—and these fans definitely contribute a lot to that.” The Lian Li UNI Fan SL-INF 120 RGB Infinity Mirror ARGB Black doesn’t just cool your system—it turns it into a visual showcase. With a community average rating hovering between 4.7 and 4.8/5 across platforms, they’ve earned a reputation for marrying premium aesthetics with solid performance.
Quick Verdict: Conditional – Ideal for builders prioritizing high-end RGB aesthetics and clean cabling, but buyers should be aware of occasional controller/software quirks and higher pricing.
| Pros | Cons |
|---|---|
| Striking infinity mirror RGB effects visible from all angles | Controller occasionally fails to detect fans |
| Daisy-chain design minimizes cable clutter | Fan pads may have weak adhesive and sag |
| Strong airflow (~61.3 CFM) and quiet performance | Price higher than many competing RGB fans |
| Easy installation with quick pin connection | RGB color tones may not perfectly match other brands |
| Quality Fluid Dynamic Bearing for longevity | Some users report software bugs with L‑Connect 3 |
| Compatible with both standard and reverse blade orientations | Extra controller purchase needed for single packs |
Claims vs Reality
Lian Li markets these fans as “quiet at high RPM” and capable of “seamless quick-connect installations.” Digging into real user feedback, the noise claims generally hold up. Reddit user feedback praised that “noise level at max rpm is quiet… barely noticeable.” This silence is especially valued by streamers and content creators who need cooling without mic interference.
Cable management claims are also largely validated. Multiple users across PCPartPicker and LDLC noted that the daisy-chain design significantly improved the tidiness of their setups. A verified buyer on LDLC explained, “The fact that there's only one cable also makes them easier to store neatly.”
However, the promotional narrative of flawless controller and software synergy doesn’t always withstand scrutiny. While many report smooth performance from L‑Connect 3, some Reddit threads detail “times when it doesn’t recognize some of the fans,” leading to troubleshooting frustration. One Reddit user admitted to “preparing to replace all of them” after persistent controller detection issues.
Cross-Platform Consensus
Universally Praised
Across Amazon, Reddit, PCPartPicker, and LDLC, the infinity mirror lighting is the undisputed star. Builders aiming for a showcase PC find the layered reflections unique compared to standard RGB fans. A PCPartPicker reviewer wrote, “Oh my god you are so beautiful… absolutely lovely fans. My temps are great too.” RGB customization depth via L‑Connect 3 comes up repeatedly, with users enjoying separate control over blade, hub, and side strip lighting. For themed builds, this granular control allows perfect alignment with case and peripherals.
Clean cabling via a modular daisy-chain system is another major win, especially for compact or glass-panel builds where clutter is unforgivable. LDLC buyer alexisd said they were “absolutely delighted with the performance and appearance… thanks to the daisy chain system.”
Finally, performance isn’t sacrificed for looks. Users gaming or rendering under load report well-controlled temperatures, validating the airflow and static pressure specs. One PCPartPicker reviewer even called them “worth every penny… easily the best looking RGB fans on the market” while maintaining system performance.
Common Complaints
Pad adhesion issues emerged as a recurring annoyance. A Reddit critical review mentioned “pads do not stay in place on corners… defective glue.” While not a performance-killer, it detracts from premium expectations.
The controller draws mixed feedback. Some claim flawless operation; others describe intermittent fan recognition or complete blade shutdown mid-use. Reddit user ‘I am somewhat regretting my purchases’ detailed repeated quirks where “one or more fans intermittently didn’t turn on,” eventually leading them to switch brands.
Software experiences with L‑Connect 3 vary. While many praise its capabilities, others find it “lacking” or sensitive to hardware context, especially with newer AIOs featuring LCD screens. Incompatibility with certain motherboard RGB suites (like ASUS Armoury Crate) occasionally forces manual fixes.
Divisive Features
The reverse blade version—intended for aesthetic intake while maintaining infinity effects—wins points from some users for lower wind noise on radiators, but not all see the benefit. Marketing touts “consistent appearance no matter intake or exhaust,” yet some prefer standard orientation for slightly better airflow-to-noise balance.
RGB color tone warmth is another split point. Some note the LEDs skew cool-blue compared to other components, but given L‑Connect 3’s adjustment features, this is fixable for those willing to tweak.
Trust & Reliability
Trustpilot and Fakespot analysis suggest authentic reviews with minimal deception, reinforcing buyer confidence. Reports of individual defects—like adhesive issues or controller quirks—are present but matched by responsive Lian Li support offering replacements.
Long-term Reddit accounts describe 6–12 months of ownership with mechanical reliability intact, aside from isolated hub/software mishaps. Fluid Dynamic Bearings live up to their durability claims, with no widespread noise escalation over time.
Alternatives
Within Lian Li’s own ecosystem, the AL120 series gets mentioned as a competitor with slightly different lighting aesthetics and pad construction. One Reddit critical review preferred the AL120’s pad reliability while conceding the SL‑INF looks “slightly better.” Builders needing consistent pads and less emphasis on infinity effects may lean that way, but at the cost of the distinctive visual style.
Price & Value
Current pricing hovers around $84–$100 for triple packs, with single packs at ~$25—but remember, single packs require a separate controller purchase. eBay and Tokopedia listings indicate strong resale potential due to demand, particularly in niche color/airflow orientations (reverse blades in white command slightly higher resale margins).
Community buying tips are clear: purchase at least one triple pack for the controller if you plan to expand, and watch motherboard hub compatibility. Fakespot reviewers warn that ASUS Armoury Crate may conflict without proper setup.
FAQ
Q: Do I need a controller for single fan packs?
A: Yes. Single packs do not include a controller, which is required for L‑Connect 3 RGB and PWM management. Many users recommend starting with a triple pack to secure one.
Q: How quiet are these fans under load?
A: Multiple users report that even at 2100 RPM, noise remains “barely noticeable,” making them suitable for streamers or quiet desk setups.
Q: Can I use motherboard software instead of L‑Connect 3?
A: Yes. Users often set fans via L‑Connect initially, then switch control to their motherboard or programs like SignalRGB for ongoing use.
Q: What’s the difference between standard and reverse blade models?
A: Reverse blades are designed to intake air while maintaining the infinity RGB visual. They can have slightly lower wind noise when used on radiators.
Q: Do the RGB tones match other brands well?
A: Not always. Some users note a cooler-blue bias, but this can be adjusted via L‑Connect 3 customization.
Final Verdict: Buy if you’re a PC builder chasing standout RGB design with streamlined cabling and solid cooling. Avoid if controller/software stability is a deal-breaker or budget is tight. Pro tip from the community: “Don’t forget to buy at least one three pack for the controller”—it’ll save you money and headaches later.
