Lian Li UNI Fan SL-INF 120 Review: Stylish But Costly
The first thing that jumps out about the Lian Li UNI Fan SL-INF 120 RGB Infinity Mirror ARGB Black is how often users describe them as “the best-looking RGB fans on the market” while still delivering solid cooling performance. Across Reddit threads, PCPartPicker logs, and Trustpilot reports, the tone is overwhelmingly positive—though some unexpected flaws keep the score at 8.5/10 rather than perfect.
Quick Verdict: Conditional Buy — excellent for style-conscious builders who value easy cable management, but minor quality control issues and high price mean they’re not for everyone.
| Pros | Cons |
|---|---|
| Stunning infinity mirror lighting effect | Premium pricing compared to rivals |
| Quiet operation at high RPM | Occasional adhesive failure on corner pads |
| Daisy-chain design reduces cable clutter | Controller required for full functionality |
| Strong airflow with reverse blade option | Software feels dated to some users |
| Easy installation with removable keylocks | Minor RGB color tone mismatch with other devices |
| Customizable lighting via L-Connect 3 | Limited compatibility issues with certain motherboard software |
Claims vs Reality
One major marketing point is the “infinity mirror design visible from any angle.” Digging deeper, this is one of the few claims that’s unanimously confirmed by real users. A PCPartPicker reviewer gushes: “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.”
Another claim is “low noise levels even at high fan speed.” Reddit user satisfaction here aligns with specs: “Noise level at max rpm is quiet… barely noticeable,” posted one owner, echoing Lian Li’s listed 32 dB maximum. It’s notable that even those pushing the fans at higher RPMs report little distraction, making them appealing for streamers or creators working in quiet environments.
However, “advanced software control through L-Connect 3” earns both praise and skepticism. Multiple buyers highlight its ease of use — “L Connect 3 software is easy to use,” says a PCPartPicker user — yet others note shortcomings. One owner on Trustpilot admits the “latest software is lacking… hopefully that improves,” showing the interface isn’t perfect for everyone.
Cross-Platform Consensus
Universally Praised
The visual appeal is the standout: shimmering infinity mirrors and bright ARGB LEDs are repeatedly called “absolutely beautiful.” For glass-sided cases or showcase builds, both casual hobbyists and experienced modders find the look elevates their setups. A verified buyer on PCPartPicker noted, “Bright and vibrant colors… the ‘infinity mirror’ looks very nice” when paired with multi-fan arrays.
Performance-wise, airflow up to 63.6 CFM on reverse blade models gives tangible cooling benefits. Reddit users report lower internal temperatures without a noise penalty. One summed it up: “They keep the inside of the case really cool… being able to daisy-chain the fans and remove attach brackets really adds to the clean look,” pointing to the practical side of the modular design.
Cable management earns consistent applause. The daisy-chain system allows up to four fans per cable, ideal for complex builds or radiator setups. “Minimal wires… daisy chain works great and the fans feel extremely premium,” wrote a Trustpilot reviewer. For dual-chamber or compact cases, this design feature can be transformative.
Common Complaints
The key frustration is adhesive pad failure. “Pads sag and come off easily,” laments a Reddit user comparing them unfavorably to Lian Li AL120s. This affects aesthetics and potentially vibration dampening, a bigger issue for perfectionists or high-vibration environments.
Software gripes appear in multiple sources. Owners describe L-Connect 3 as functional but dated, with occasional device sync issues. Some PC builders, particularly those using ASUS motherboards, encounter conflicts between Lian Li’s software and Armoury Crate: “Aura Sync and Lian Li software fight for dominance and constantly resets my USB connections,” warns one Trustpilot post.
Price sensitivity is another pain point. “Ridiculously priced… I almost didn’t want to buy them,” admits a cost-conscious buyer, though they conclude the performance and visuals justify it. For budget builders, the unit cost—especially when factoring in the required controller—may feel steep.
Divisive Features
The reverse blade option is one area where opinions split. Designed for intake with lower wind noise, some praise its quieter radiator operation, while others note the effect is “more obvious when installed on a radiator” — implying minimal benefit in other mounting positions.
RGB tone matching is divisive. One PCPartPicker user notes, “Fans run quite blue/cool tone but I can fix that through software,” hinting small mismatches with other RGB gear. For meticulous color-sync enthusiasts, this may be a deal-breaker; most casual users adjust via software and move on.
Trust & Reliability
Trustpilot patterns suggest minimal deception in reviews, with over 80% considered high quality. Durability-wise, several users report months of flawless operation. However, corner pad adhesive issues raise questions about long-term physical integrity, even as fans continue working electrically. While many say they would “buy again,” the hope is that future runs improve these small build inconsistencies.
On compatibility, scattered reports of initial setup troubles—often with certain motherboard RGB control systems—mean prospective buyers should double-check their ecosystem. One Trustpilot note captures this: “If you go with an ASUS motherboard I had issues… found out the issue was with the ASUS Armoury software.”
Alternatives
The AL120 series from Lian Li is the most direct competitor. Owners of both point out that while SL-INF looks “slightly better” and offers the infinity mirror, AL120 avoids the corner pad adhesive issue. Price points are close, so the choice leans on whether visual flair or proven mechanical execution matters more.
Price & Value
Amazon lists the triple pack with controller at $107.72 (8% off), while eBay shows prices ranging from $83.99 plus shipping to $149.99 depending on configuration. Given the resale listings, the product holds its value well in enthusiast markets—indicating sustained demand for the design. Community buying tips emphasize: “Don’t forget to buy at least one three pack for the controller,” as single fans lack it.
FAQ
Q: Do the SL-INF fans require a controller?
A: Yes, for full lighting and speed control via L-Connect 3. Single packs don’t include it, so at least one triple pack is recommended.
Q: Are they compatible with ASUS Aura Sync?
A: Technically yes, but some users note conflicts between Armoury Crate and L-Connect 3, causing device resets.
Q: How noisy are they at max RPM?
A: Rated up to 32 dB, with multiple buyers stating they are “barely noticeable” even at full speed — ideal for quiet rooms.
Q: Is the reverse blade worth it?
A: Beneficial for intake on radiators with slightly better airflow and lower wind noise; less impactful in other positions.
Q: Do corner pad issues affect performance?
A: They mainly impact aesthetics and vibration dampening; performance remains strong despite adhesive failures.
Final Verdict: Buy if you’re an RGB enthusiast prioritizing showcase aesthetics and clean cable routing. Avoid if you’re price-sensitive or have zero tolerance for minor build flaws like pad adhesive issues. Pro tip from the community: secure at least one three-pack for the controller, and check motherboard software compatibility before purchase.
