Lian Li UNI Fan SL-INF 120 Review: Premium RGB Verdict
Few PC components earn universal praise across Reddit, Trustpilot, and PCPartPicker, but the Lian Li UNI Fan SL-INF 120 RGB Infinity Mirror ARGB Black sits at a rare 9.5/10 in aggregated user sentiment. Its striking triple-zone RGB with infinity mirror effects has captivated aesthetic-focused builders, while the wireless daisy-chain design drastically reduces cable clutter — “absolutely perfect,” as LDLC customer alexisd described after daisy-chaining multiple tripacks in his setup.
Quick Verdict: Conditional Buy – stellar for RGB-heavy tempered glass case builds but less ideal for budget-conscious users due to pricing.
| Pros | Cons |
|---|---|
| Gorgeous triple-zone RGB & infinity mirror | High price compared to rivals |
| Quiet operation even at high RPM | Corner pads reported to fall off |
| Wireless daisy-chain for clean builds | Software conflicts on some motherboards |
| Solid airflow & performance | Controller sold separately for single packs |
| Easy to install & configure | Reverse blade model slightly louder |
| Durable fluid dynamic bearings | Limited customization without L-Connect 3 |
| Available in reverse blade option | Small install quirks (screen protector fit) |
Claims vs Reality
The marketing boasts “cableless RGB and PWM sync” with the ability to cluster fans via a single receiver. Digging into user feedback, this claim is overwhelmingly validated. PCPartPicker builder reviews consistently mention how effortless wiring becomes: “super easy to install and wire with the fan hubs,” wrote one reviewer who linked four fans off one cable.
Another bold claim is “58 addressable LEDs per fan for immersive lighting effects.” While owners agree the RGB is vibrant and layered, the overall wow factor depends heavily on case visibility. Reddit user feedback reveals these deliver best results in dual-chamber or aquarium-style cases—otherwise some lighting zones are hidden. LDLC customer florian m noted the “mirror effect really gives the tower a spectacular look” only because his build maximized the angles.
Lastly, Lian Li promotes “quiet power” with 29 dBA max noise for standard blades. In reality, users back this up for the normal model, but reverse blade configurations draw higher noise comments. A verified buyer on Amazon.de recorded “low volume of just 32 dBA” but also noted the airflow advantage, suggesting a tradeoff worth weighing.
Cross-Platform Consensus
Universally Praised
The visual design is the standout. PCPartPicker’s top-rated fans section brims with comments about “bright and vibrant colors” and the “infinity mirror” effect being jaw-dropping. For streamers and showcase builders, color accuracy and range are key—LDLC customer erict wrote the RGB is “superb” and praised software integration with the hub.
Installation simplicity is another strong point. The daisy-chain mechanism not only minimizes cabling but allows cleaner mounting in tight layouts. Trustpilot reviewers repeatedly mention “minimal wires” and “easy to install” as transformative versus traditional ARGB fans. This especially benefits modders working with custom loops who need unobstructed paths.
Performance metrics receive similar acclaim. With up to 67 CFM airflow and fluid dynamic bearings, users see measurable cooling improvements. Reddit user accounts frequently mention components running cooler under load with SL-INF fans in place, without a noise penalty for the standard orientation models.
Common Complaints
Price is the recurring sore spot. Fakespot analysis bluntly includes “ridiculously priced” in the pros/cons split. Even satisfied owners concede these are premium fans, advising them primarily for enthusiasts who value both aesthetics and performance.
A physical wear issue pops up in critical reviews: corner rubber pads detaching. One Reddit user cited “defective glue” on a set, forcing an RMA process with Lian Li. This affects mounting stability and dust sealing, especially in vertical orientations.
Software conflicts are the most disruptive problem for certain setups. Those with ASUS motherboards sometimes encounter L-Connect 3 and Armoury Crate contention, leading to RGB desync or USB port resets. A Trustpilot reviewer advised double-checking controller compatibility to avoid hours of troubleshooting.
Divisive Features
Reverse blade versions are a stylistic and airflow upgrade for intake mounts but draw mixed noise feedback. Amazon.de’s technical specs show higher CFM and slightly higher dBA, aligning with Reddit notes on modestly louder operation. Builders using reverse blades on radiators often praise the wind tone reduction, but others find the tradeoff in noise unacceptable.
The controller policy is another split issue—single packs ship without one, frustrating first-time buyers unaware they will need an extra purchase. Experienced users defend the choice as a cost-saver when expanding existing groups.
Trust & Reliability
Patterns across Trustpilot and Reddit point to strong durability thanks to fluid dynamic bearings. Several owners report months of 24/7 operation without degradation in cooling or lighting. The only notable hardware flaw making rounds is the aforementioned pad adhesive issue, which Lian Li appears to resolve promptly through replacements.
Scam concerns are minimal; Fakespot’s analysis found “minimal deception” and over 80% high-quality reviews. The main trust element with this product lies in Lian Li’s broader brand reputation—the company’s decades-long cachet reassures buyers. However, caution is advised on controller/software integration for those mixing ecosystems.
Alternatives
Only one direct comparison emerged in critical Reddit reviews—AL120 series fans. These are noted as slightly behind in aesthetics but ahead in adhesive sturdiness. Owners switching from AL120 to SL-INF describe the visual upgrade as worth it if infinity mirror styling is a priority, but lament the pad issue which AL120s did not present.
Price & Value
Market prices vary wildly: eBay listings range from $59.99 for a single pack to $149.99 for a triple pack with controller. Fakespot reviewers tip value toward bundle purchases, as adding controllers separately bumps cost significantly. LDLC customers paying around €119.95 for a tripack spoke of them as “well worth the price” only when factoring in aesthetic impact.
For resale, PicClick data puts average triple pack value near $62.90, suggesting moderate depreciation for used sets. Community advice leans toward buying in bulk now if planning a full RGB case build rather than piecemeal later.
FAQ
Q: Do I need a controller for a single fan pack?
A: Yes, single fan packs do not include the controller. You’ll need to purchase one separately for RGB and speed control unless adding to an existing SL-INF setup.
Q: How loud are the reverse blade fans compared to standard?
A: Reverse blades produce slightly higher noise at max RPM (~32 dBA) but can deliver better intake airflow and lower wind tone when used on radiators.
Q: Can these fans sync with my motherboard’s RGB software?
A: They can, but conflicts may occur with ASUS Armoury Crate. Some users recommend sticking to L-Connect 3 for consistent results.
Q: Are the corner pads falling off a common issue?
A: It’s not widespread but several users have reported defective adhesive. Lian Li typically replaces affected fans under warranty.
Q: Will the lighting look good in cases without glass panels?
A: The lighting is best appreciated in builds with high visibility—tempered glass side panels or open frame cases maximize the infinity mirror’s effect.
Final Verdict: Buy if you’re building a showcase PC and want top-tier RGB with minimal cabling. Avoid if you’re on a tight budget or mixing multiple RGB control ecosystems. Pro tip from community: bundle tripacks with controllers up front—expanding later is more expensive and risks software mismatches.
