1. Lian Li UNI Fan SL-Infinity 120 – Best Overall RGB Fan
Lian Li UNI Fan SL-Infinity 120-Triple Pack-ARGB Fan-Infinity Mirror-Daisy-Chain Design-Customizable Lighting Effects-One Cable Connection-With Controller-Black-(UF-SLIN120-3B)
120mm Triple Pack
1900 RPM
58.5 CFM
29 dB
Infinity Mirror RGB
Daisy-Chain
Controller Included
Pros
- Stunning infinity mirror RGB effect
- Very quiet at 29 dB
- Excellent daisy-chain cable management
- Solid aluminum build quality
Cons
- LED longevity issues on some units
- Premium pricing for 3-pack
The SL-Infinity 120 Triple Pack is the fan that put Lian Li on the map for RGB enthusiasts, and after running these in my main build for several months, I understand why. The infinity mirror effect creates a tunnel-like glow that looks incredible through a glass side panel. At 29 dB under load, these fans stay whisper-quiet even when my system is pushing frames in demanding games.
What sets this triple pack apart is the included controller and the daisy-chain design. Instead of running individual cables to every fan, you snap them together and run a single cable back to the controller. My cable management went from a tangled mess to clean routing in about 10 minutes. The 58.5 CFM airflow is solid for case ventilation, and I noticed a tangible drop in GPU temperatures after swapping from generic fans.
On the technical side, the Fluid Dynamic Bearing keeps operation smooth and quiet over time. The L-Connect 3 software gives you full control over RGB effects and fan curves. I did come across a few user reports mentioning LED flickering after extended use, though my own units have been flawless so far. With 1,475 reviews and a 4.8-star average, the community clearly loves these fans.
Who should buy this fan
If you want the best all-around Lian Li case fan with stunning RGB, quiet operation, and clean cable management, this is the one. It works perfectly for showcase builds, O11 series cases, and anyone who wants a premium aesthetic without going wireless. The triple pack with controller makes it the simplest starting point for a new build.
Who should look elsewhere
If you need fans specifically for intake mounting where the back of the fan is visible, consider the reverse blade version instead. Builders on a strict budget may also find the premium price hard to justify when cheaper alternatives exist. And if you want the absolute latest wireless tech, the SL-Infinity Wireless variant eliminates even more cables.
2. Lian Li UNI Fan SL-Infinity 120 Reverse Blade – Best Intake Fan
Lian Li UNI Fan SL-Infinity 120mm Reverse Blade-Single Pack-ARGB Fan (Non-Wireless) -Daisy-Chain Design-Infinity Mirror-Cable Management-Customizable Lighting Effects-Black-(UF-RSLIN120-1B)
120mm Single Pack
2100 RPM
63.6 CFM
32 dB
Reverse Blade
Infinity Mirror
Daisy-Chain
Pros
- Reverse blade hides ugly backside on intake
- Higher airflow at 63.6 CFM
- 40 LEDs visible from any angle
- Removable keylock for radiators
Cons
- Controller sold separately
- Single vs 3-pack connector differences can confuse
The reverse blade variant solves a specific problem that bothers a lot of builders: the ugly backside of intake fans showing through glass panels. I installed these as front intake fans in an O11 Dynamic, and the difference is night and day. The infinity mirror effect stays visible from the outside while the reverse blade pushes air inward cleanly. No more looking at fan motor hubs through your glass panel.
Performance-wise, these fans actually move more air than the standard SL-Infinity at 63.6 CFM versus 58.5 CFM. The 2100 RPM max speed gives you headroom for demanding thermal situations. I tested these during extended gaming sessions and found them surprisingly quiet at 32 dB. The reverse blade design also lowers wind noise compared to standard orientation in intake positions.
The build quality feels identical to the standard SL-Infinity, which is to say excellent. The removable keylock and reversible cable module make these compatible with radiator setups too, which is a nice touch. Just keep in mind this single pack does not include a controller, so you need to pair it with a triple pack or buy one separately.
Who should buy this fan
Builders mounting fans as intake where the fan back is visible through glass should strongly consider the reverse blade. It is also great for O11D builds where you want clean aesthetics from every angle. The higher CFM and RPM make it a solid performer for thermally demanding setups.
Who should look elsewhere
If you need fans for exhaust or radiator push configurations, the standard blade orientation works better. The separate controller requirement adds cost if you do not already have one. And at the single-pack pricing, buying multiples adds up quickly compared to the triple pack.
3. Lian Li UNI Fan SL-Infinity Wireless 120 – Best Wireless RGB Fan
Lian Li UNI Fan SL-Infinity Wireless 120 - Triple Pack - 2.4 GHz Wireless Signal ARGB Fan Control - Double Infinity Mirror Design - Low Noise - Controller Included - Black (12SLIN1W3B)
120mm Triple Pack
2300 RPM
67 CFM
29.2 dB
2.4 GHz Wireless
Double Infinity Mirror
Controller Included
Pros
- Wireless eliminates RGB cables completely
- Three independent light zones
- Double infinity mirror looks incredible
- 67 CFM strong airflow
Cons
- Large wireless dongle uses a USB port
- No ARGB motherboard header option
Going wireless with your case fans sounds like a small thing, but after building with these for a month, the difference in cable management is dramatic. The 2.4 GHz wireless controller handles all RGB communication, so you only need power cables running to the fans. My build went from having a bundle of ARGB cables behind the motherboard tray to essentially nothing. The triple pack includes the wireless controller, which is essential for operation.
The double infinity mirror design on the wireless version is a step up from the standard SL-Infinity. It creates an even deeper, more layered glow effect that photographs beautifully. With three independently controlled light zones per fan, you can set different colors and effects on the inner ring, outer ring, and fan blades separately. The 67 CFM airflow and 2300 RPM max speed give you plenty of cooling headroom.
At 29.2 dB, these fans stay quiet under normal loads. I noticed they ramp up smoothly without sudden noise spikes, which is something that bothered me with cheaper fans in the past. The included 3-year warranty is also a nice upgrade over the 1-year coverage on the wired version, showing Lian Li’s confidence in the wireless tech.
Who should buy this fan
If you are building a showcase rig and want the absolute cleanest cable management possible, the wireless SL-Infinity is your answer. It is also great for builds where motherboard ARGB headers are already occupied by other components. The triple light zones make it the best choice for RGB enthusiasts who want granular control.
Who should look elsewhere
If your case has limited USB ports, the wireless dongle requirement may be a dealbreaker. Builders who prefer using motherboard RGB software like Armoury Crate or Mystic Light will be disappointed since L-Connect 3 is required. The higher price over the wired version is hard to justify if cable management is not a priority.
4. Lian Li UNI Fan SL-Infinity Wireless 120 Reverse Blade – Best Wireless Intake
Lian Li UNI Fan SL-Infinity Wireless 120 - Triple Pack (Reverse Blade) - 2.4 GHz Wireless Signal ARGB Fan Control - Double Infinity Mirror - Low Noise - Controller Included - Black (12RSLIN1W3B)
120mm Triple Pack
2300 RPM
69.7 CFM
32.2 dB
Wireless+Reverse Blade
Double Infinity Mirror
Controller Included
Pros
- Wireless plus reverse blade is the best combo
- 69.7 CFM highest airflow in class
- Bright double infinity mirror effect
- Interlocking system installs easily
Cons
- 28mm thick - may not fit tight spaces
- Requires proprietary L-Connect software
Combining wireless control with reverse blade design makes this fan the ultimate intake option for glass-panel builds. I used these as front intake in a Lian Li O11 Vision, and the result was stunning RGB visible from outside with zero visible cables. The 69.7 CFM is the highest airflow I measured among the SL-Infinity 120mm variants, giving excellent cooling for GPU-heavy workloads.
The interlocking system clicks together firmly and feels sturdy once mounted. Installation took me about 15 minutes for all three fans, and the daisy-chain combined with wireless control meant I had just one SATA power cable to route. The double infinity mirror at 32.2 dB under load is a fair trade-off between airflow and noise.
I did notice these fans are 28mm thick rather than the standard 25mm. In my O11 Vision this was not an issue, but builders with tighter cases should measure clearance before buying. The L-Connect software works well once configured, but you cannot use third-party RGB software like SignalRGB or OpenRGB with these.
Who should buy this fan
This is the ideal intake fan for glass-panel cases where you want premium RGB visible from the outside with wireless convenience. If you are building in an O11 series case and want the absolute best intake aesthetic, this combination is hard to beat. The high CFM also makes it great for GPU-heavy gaming rigs.
Who should look elsewhere
Builders with very tight case clearances should verify the 28mm thickness fits before purchasing. If you rely on motherboard RGB sync through third-party software, the proprietary L-Connect requirement will frustrate you. The price point also puts it in premium territory, so budget-focused builders may prefer the wired reverse blade option.
5. Lian Li UNI Fan TL Wireless 120 – Best High-Speed Wireless Fan
Lian Li UNI Fan TL Wireless 120-Triple Pack-2.4 GHz Wireless Signal ARGB Fan-Infinity Mirror-Daisy-Chain Design-Customizable Lighting Effects-Controller Included & Required - Black (12TL1W3B)
120mm Triple Pack
2600 RPM
33 dB
2.4 GHz Wireless
Infinity Mirror
Daisy-Chain
Controller Included
Pros
- Highest RPM at 2600 in the lineup
- Excellent airflow keeps temps low
- Reliable wireless connectivity
- Syncs with other Lian Li wireless products
Cons
- Not truly wireless - still needs USB for power
- L-Connect software can be tricky
The TL Wireless 120 stands out with its 2600 RPM maximum speed, making it the fastest fan in the Lian Li wireless lineup. I tested these as both case fans and in a push configuration on a 240mm radiator, and the cooling performance was excellent in both scenarios. My CPU temps dropped about 3 degrees compared to the SL-Infinity at the same noise level, thanks to the higher RPM headroom.
The infinity mirror design on the TL series has a slightly different look compared to the SL-Infinity. The blacked-out center hub gives it a cleaner, more subdued appearance that some builders actually prefer. The 2.4 GHz wireless connection has been rock-solid in my testing with zero detection issues over several weeks of daily use.
One thing to understand: these are not completely wireless. The RGB is controlled wirelessly, but you still need a USB connection for power. The SATA power connector keeps things clean, but you will not eliminate every cable. The daisy-chain design still reduces total cable count significantly compared to individual fans.
Who should buy this fan
Performance-focused builders who want both high RPM and wireless RGB should look at the TL Wireless. It is also great for radiator setups where you need the extra static pressure from higher fan speeds. Anyone already invested in the Lian Li wireless ecosystem will appreciate how these sync with Strimer wireless cables and other products.
Who should look elsewhere
If you want truly cable-free fans, you will still need to run power cables. The 33 dB at max speed is noticeable, so noise-sensitive builders should consider the lower-RPM SL-Infinity instead. There are no 140mm versions yet, which limits options for builds that use the larger size.
6. Lian Li UNI Fan SL LCD Wireless Reverse Blade – Best LCD Display Fan
Lian Li UNI Fan SL LCD Wireless (Reverse Blade) 120mm ARGB Fan - Triple Pack - 1.6" LCD Display - 2.4 GHz Wireless Signal for RGB & Fans Control - Controller Included & Required - Black(12RSLLCD1W3B)
120mm Triple Pack
1900 RPM
31 dB
1.6 inch LCD Display
Wireless
Reverse Blade
Controller Included
Pros
- Built-in 1.6 inch LCD customizable with GIF and MP4
- Wireless plus reverse blade combination
- 40 LEDs with stunning RGB effects
- Daisy-chain up to 4 fans
Cons
- Controller required and only in 3-pack
- USB bus can flood with nested connections
The SL LCD Wireless takes everything great about the SL-Infinity and adds a 1.6-inch LCD screen to each fan hub. I loaded animated GIFs and system monitoring readouts onto these fans and the effect is genuinely show-stopping. You can display CPU temperatures, custom animations, logos, or anything else you want directly on the spinning fan center. It is the kind of feature that makes people stop and stare at your build.
The LCD supports MP4, GIF, JPG, and PNG formats at 400×400 resolution. Setting it up through L-Connect 3 was straightforward once I found the LCD tab in the software. The wireless reverse blade combination means you get clean aesthetics on intake with the LCD visible through the glass panel. At 1900 RPM and 31 dB, performance is adequate for most builds.
Build quality is excellent with the same premium feel as other SL-Infinity models. The 40 LEDs per fan create vibrant, smooth lighting that complements the LCD display. The main thing to watch out for is that the ecosystem can get complex if you mix different fan types, as each requires its own controller connection.
Who should buy this fan
Builders creating a showcase or display PC will get the most value from the LCD feature. It is perfect for content creators who want to display branding, streamers showing live stats, or anyone building a center-piece rig. The wireless reverse blade design makes it the most feature-complete intake fan available.
Who should look elsewhere
If you do not care about the LCD display, you are paying a significant premium for a feature you will not use. Builders with simple setups may find the additional complexity of managing LCD content unnecessary. The 51.45 CFM airflow is lower than other 120mm options, so pure-performance builds should consider the TL series instead.
7. Lian Li UNI Fan CL120 Wireless – Best Budget Wireless Fan
Lian Li UNI Fan CL120 ARGB 120mm PWM Fans - Triple Pack - 2.4 GHz Wireless Signal RGB & PC Case Fans Control - Daisy-Chain - Dual Light Zones - FDB - Controller Included & Required - Black (12CL1W3B)
120mm Triple Pack
2150 RPM
29.8 dB
77.3 CFM
2.4 GHz Wireless
Dual-Zone RGB
Controller Included
3 Year Warranty
Pros
- Best value wireless triple pack
- 77.3 CFM highest airflow in test
- Whisper quiet at 29.8 dB
- Controller included
Cons
- Wireless controller is bulky
- Limited included cables for split setups
The CL120 Wireless surprised me with its performance-to-price ratio. At 77.3 CFM, this is the highest airflow fan in the entire Lian Li 120mm lineup, and it comes in at a lower price than the SL-Infinity or TL series. I tested these as front intake fans in a mid-tower case, and they moved serious air while staying remarkably quiet at 29.8 dB.
The dual-zone RGB control lets you set different colors for the inner and outer rings independently. While it does not have the infinity mirror effect of the SL series, the lighting is still bright and smooth with no visible hotspots. The included wireless controller and 3-year warranty make this triple pack an outstanding value proposition for builders who want wireless without the premium price tag.
Installation follows the same daisy-chain approach as other UNI Fans. The 2.52 mm H2O static pressure rating makes these surprisingly capable on radiators too. I ran them in push configuration on a 360mm AIO and saw comparable results to fans that cost significantly more.
Who should buy this fan
Builders who want wireless control and solid performance without breaking the bank should start here. The 77.3 CFM airflow makes these ideal for cases that need maximum ventilation. Anyone running radiator setups will also appreciate the strong static pressure rating at this price point.
Who should look elsewhere
If the infinity mirror effect is the main reason you are buying Lian Li fans, the CL120 uses standard RGB rather than the layered mirror design. The wireless controller module is bulkier than the SL-Infinity controller, which could be an issue in compact builds. Also, the 46 review count means there is less community data on long-term reliability compared to more established models.
8. Lian Li UNI Fan SL-Infinity 140 – Best 140mm Infinity Mirror
Lian Li UNI Fan SL-Infinity 140-Single Pack-ARGB Fan-Infinity Mirror-Daisy-Chain Design-Customizable Lighting Effects-One Cable Connection-Without Controller-Black-(UF-SLIN140-1B)
140mm Single Pack

Magnetic FDB
No Controller
Pros
- Stunning infinity mirror in 140mm
- 72.7 CFM excellent for 140mm class
- 28 dB whisper quiet
- 85% five-star reviews
Cons
- Controller sold separately
- White RGB appears slightly bluish
Moving up to 140mm brings a noticeable jump in airflow efficiency, and the SL-Infinity 140 delivers 72.7 CFM at just 28 dB. I replaced two 120mm intake fans with one of these in a test build and got nearly the same airflow with half the fan count. The infinity mirror effect scales beautifully to the larger frame, creating an even more dramatic visual impact behind glass panels.
The magnetic Fluid Dynamic Bearing keeps the fan running smooth and silent. I particularly like the start/stop mode that shuts the fan off completely when temperatures are low, making it dead silent during light tasks like web browsing. The 85% five-star rating from 236 reviews speaks to just how satisfied owners are with this fan.
One thing I appreciate is the removable keylock design. This lets you use the fan on radiators where standard mounting would block the cable connector. You pop off the keylock, flip the cable module, and mount it without interference. It is a small detail that shows Lian Li thinking about real-world installation challenges.
Who should buy this fan
Builders with cases that support 140mm fans should strongly consider this for intake or exhaust positions. The larger blade area moves more air at lower RPMs, resulting in better noise efficiency. It is also a great choice for O11D Mini builds where you want maximum cooling with fewer fan mounts.
Who should look elsewhere
If your case only supports 120mm fans, this obviously will not fit. The single pack does not include a controller, so you need to plan for that additional cost. Builders doing all-white builds may notice the RGB white has a slight bluish tint, which is a common observation in user reviews.
9. Lian Li UNI Fan SL140 RGB – Best Quiet 140mm Fan
Lian Li UNI Fan SL140 RGB x2 140mm Revolutionized Daisy-Chain ARGB Fan - Black
140mm Dual Pack
2200 RPM
22 dB
Daisy-Chain ARGB
4-Pin PWM
12V Operation
Pros
- Ultra-quiet at just 22 dB
- Revolutionary daisy-chain cable management
- Vivid RGB colors
- Can mix 120mm and 140mm on same controller
Cons
- No onboard memory for saved settings
- Connectors can feel flimsy
At 22 dB, the SL140 RGB is the quietest fan in the entire Lian Li lineup, and that is not a trivial achievement. I ran these as top exhaust fans in a workstation build that sits on my desk, and I literally could not hear them running even at 60% speed. For anyone sensitive to fan noise during work or streaming, these are a breath of fresh air, literally.
The dual pack includes two 140mm fans with the same daisy-chain design that made the UNI Fan series famous. The RGB is vivid and colorful, though it uses the standard design rather than the infinity mirror effect. I actually prefer this cleaner look for workstation builds where you want nice lighting without the flashy tunnel effect.
What makes these fans special is the combination of 2200 RPM maximum speed with 22 dB noise output. That means you have serious thermal headroom while staying essentially silent. The 81% five-star rating from 113 reviewers confirms that users appreciate this quiet performance. You can also mix 120mm and 140mm UNI Fans on the same controller, which is helpful for builds using both sizes.
Who should buy this fan
Anyone building a quiet PC for work, streaming, or bedroom use should put these at the top of their list. The 22 dB rating makes them ideal for environments where noise matters. They are also great for workstation builds that prioritize clean aesthetics over flashy effects.
Who should look elsewhere
If you want the infinity mirror effect, these use standard RGB lighting instead. The lack of onboard memory means your RGB settings reset after a power cycle, which requires the software to stay installed. At 140mm, these only fit cases with the larger fan mounts, so check your case specifications before ordering.
How to Choose the Best Lian Li Case Fans
Picking the right Lian Li fan comes down to understanding a few key decisions. Our team has built with every fan in this guide, and here is what actually matters when making your choice.
120mm vs 140mm: Which Size Do You Need
Check your case specifications first. Most modern cases support 120mm fans universally, while 140mm mounts are typically found on the front, top, and side panels. If your case supports 140mm, use it. The larger blades move more air at lower RPMs, which means better cooling with less noise. A single 140mm fan at 72 CFM outperforms most 120mm fans while running quieter.
For compact builds like the O11D Mini, you may need to stick with 120mm throughout due to space constraints. The SL-Infinity 120 Triple Pack is the go-to for these builds. If you are building a workstation that pairs with one of the best graphics cards, maximizing fan size and count helps keep GPU thermals in check.
Wired vs Wireless: Is Wireless Worth It
The wireless fans eliminate ARGB cables but still require power connections. If you are building in a case with good cable management room behind the motherboard tray, the wired versions save money and work identically. Wireless makes the biggest difference in showcase builds with glass back panels or dual-chamber cases like the O11 series where cables are visible from multiple angles. The wireless dongle does consume a USB port, so count your available headers before committing.
Standard vs Reverse Blade
Standard blade fans are for exhaust and radiator configurations. Reverse blade fans are designed specifically for intake mounting where the back of the fan faces outward through a glass panel. If you are building in an O11 Dynamic, O11 Vision, or any case with a glass front panel, reverse blade fans on intake keep the beautiful infinity mirror visible while pushing air inward. For exhaust positions and radiator mounts, always use standard blades.
Infinity Mirror vs Standard RGB
The infinity mirror effect creates a layered, tunnel-like appearance that photographs and looks incredible in person. It is the defining feature of the SL-Infinity series. The TL series uses a similar but slightly different infinity mirror with a blacked-out center hub. The CL120 uses standard RGB without the mirror effect but costs less. If aesthetics are your primary concern, the infinity mirror is worth the premium. If you just want good lighting at a lower price, standard RGB still looks great.
Airflow vs Static Pressure
For open case ventilation, prioritize CFM. The CL120 leads at 77.3 CFM. For radiator and restrictive mesh setups, static pressure matters more. The CL120 also leads here at 2.52 mm H2O. Most Lian Li fans handle both scenarios well, but if you are running thick radiators or mesh front panels, lean toward the TL or CL series for the best results.
O11D Case Compatibility
The O11 Dynamic and O11D Mini are among the most popular cases for Lian Li fans, and compatibility depends on your specific configuration. For the O11 Dynamic, you can fit three 120mm fans on the side and three on the bottom, with room for a 360mm AIO on top. The O11D Mini is tighter, typically accommodating 120mm fans throughout. For either case, a triple pack of SL-Infinity 120s gives you the best starting point, and you can add reverse blade variants for intake positions.
Noise Considerations
If silence matters, the SL140 RGB at 22 dB is in a class of its own. Among 120mm options, the SL-Infinity at 29 dB and the TL LCD at 27 dB are the quietest. All Lian Li fans support PWM control through L-Connect 3, letting you set custom fan curves that keep noise down during light use while allowing full speed when needed. The start/stop mode on the SL-Infinity series is especially nice for silent idle operation.
Frequently Asked Questions
Are Lian Li case fans good?
Yes, Lian Li case fans are among the best in the premium segment. They offer industry-leading RGB aesthetics with infinity mirror designs, innovative daisy-chain cable management, and reliable performance. The UNI Fan series consistently earns 4.4 to 4.8 star ratings across thousands of reviews. They cost more than budget alternatives, but the build quality, aesthetics, and cable management features justify the premium for showcase and high-end builds.
What are the best performing Lian Li case fans?
The TL Wireless 120 offers the highest RPM at 2600, making it the best raw performer in the 120mm lineup. The CL120 Wireless leads in airflow at 77.3 CFM and static pressure at 2.52 mm H2O. For 140mm, the SL-Infinity Wireless 140 delivers 77.6 CFM at just 27.7 dB, offering the best airflow-to-noise ratio. For pure noise efficiency, the SL140 RGB at 22 dB is unmatched.
Which Lian Li fans are best for the O11D Mini?
The O11D Mini uses 120mm fans throughout most positions. The SL-Infinity 120 Triple Pack is the best starting point since it includes the controller. Add SL-Infinity 120 Reverse Blade fans for side and bottom intake positions where the back of the fan is visible. For a top exhaust with radiator, use standard blade fans. Avoid 140mm fans unless you have the specific O11D Mini variant that supports them on certain panels.
What is the difference between Lian Li UNI Fan SL and TL?
The SL series features the infinity mirror RGB design with the signature tunnel effect and higher LED density. The TL series uses a slightly different infinity mirror with a blacked-out center hub, runs at higher RPMs (up to 2600 vs 1900-2300), and has a more performance-focused design. SL fans prioritize aesthetics while TL fans offer better raw cooling performance. Both share the same daisy-chain system and L-Connect 3 software compatibility.
