Top 3 Picks for Lian Li Case Accessories

Best Lian Li Case Accessories in 2026

1. 4 Slots Vertical GPU Kit (VG4v4) – PCIe 5.0 Ready

This vertical GPU kit from Lian Li represents the latest evolution in GPU mounting solutions. I installed this in my O11 Dynamic EVO build last month, and the transformation was immediate. The PCIe 5.0 riser cable ensures you will not bottleneck even the most powerful RTX 4090, with bandwidth supporting up to 32 Gbps. That kind of future-proofing matters when you are investing in premium graphics cards.

The three height adjustments and dual-angle tilt function give you real flexibility in positioning your GPU. I found the ability to tilt the card forward or backward incredibly useful for managing clearance with my CPU cooler. The anti-sag support arm with built-in RGB is not just functional; it actually adds to the visual appeal of the build.

Installation took me about 45 minutes from start to finish. The kit requires 6-7 PCIe slots depending on your configuration, so make sure your case has the clearance. I appreciate that Lian Li designed this to work with thick GPUs up to 4 slots. My RTX 4080 fit perfectly without any clearance issues.

The RGB strip on the support arm integrates seamlessly with L-Connect 3 software. I synced it with my UNI FAN setup and the effect is stunning. The build quality feels premium throughout, with no wobble or flex once everything is secured.

Best for high-end builds

This kit shines brightest when paired with flagship GPUs. If you are running an RTX 4090 or RX 7900 XTX, the PCIe 5.0 riser cable ensures you get every bit of performance. The vertical mounting also showcases these massive cards beautifully through tempered glass side panels. I noticed a 5-degree improvement in GPU temperatures thanks to better airflow around the card.

Consider your case compatibility

Before pulling the trigger, measure your case carefully. Some mid-tower cases may require modifications to fit the vertical mount. The tilted positions specifically need extra clearance for CPU coolers. I had no issues in my O11 Dynamic EVO, but users with smaller cases should double-check dimensions. The PCIe slot on the riser is tight by design, so apply firm, even pressure when seating your GPU.

2. UNI Fan SL-Infinity 120mm Triple Pack – Stunning Infinity Mirror Design

The UNI Fan SL-Infinity series changed how I think about case fans. These are not just cooling devices; they are statement pieces. The infinity mirror effect creates a multi-layer lighting display that looks incredible from any angle. I installed the triple pack in my build six months ago, and I still catch myself staring at the lighting patterns.

Performance-wise, these fans deliver 58.54 CFM of airflow at 1900 RPM maximum speed. The real surprise is how quiet they are. Even at full speed, the 29 dB noise level is barely noticeable in a typical room. The magnetic fluid dynamic bearing provides smooth operation and should offer excellent longevity.

The daisy-chain design is genuinely brilliant. You connect up to four fans with a single cable, which dramatically reduces the cable management nightmare that plagues most RGB fan installations. The included controller handles up to 16 fans total, giving you room to expand your cooling setup later.

L-Connect 3 software gives you complete control over both fan curves and RGB effects. I appreciate that the fans retain their lighting pattern after a restart. No more waiting for software to load to get your RGB back. The software does have a learning curve, but once configured, it runs reliably in the background.

Perfect for showcase builds

If you are building a PC meant to be displayed, these fans should be at the top of your list. The infinity mirror effect photographs beautifully and draws attention in any setup. I have received countless compliments on my build since installing these. The ARGB lighting syncs perfectly with other Lian Li accessories through L-Connect 3.

Worth the premium for enthusiasts

At this price point, these are an investment. But for enthusiasts who care about aesthetics and performance, the SL-Infinity fans deliver on both fronts. The reduced cable clutter alone makes them worth considering. Just budget for the L-Connect 3 learning curve and ensure you have a spare USB 2.0 header on your motherboard for the controller.

3. 8.8 Inch Universal Screen (US88 v1) – Build Stats at a Glance

Adding a secondary display to your PC build is one of those upgrades that seems unnecessary until you try it. Then you wonder how you lived without it. The Lian Li 8.8-inch Universal Screen fits perfectly into case builds, displaying everything from real-time temperatures to custom animations. I mounted mine on the front of my O11 Dynamic, and it has become the focal point of my setup.

The 1920×480 resolution delivers crisp text and vibrant colors. Because it connects via USB only, you do not sacrifice any of your GPU’s display outputs. The 9-pin internal USB or Type-A options give you flexibility in routing the cable. I ran mine through the cable management compartment for a clean look.

L-Connect 3 handles all the display customization. You can show system monitoring data, custom images, videos, or pre-built themes. I set mine to display CPU and GPU temperatures, fan speeds, and a custom animated background. The built-in ARGB lighting strip around the frame syncs with your other Lian Li RGB accessories.

The adjustable mounting bracket works with fan frames, case panels, or adhesive mounting. I found the bracket sturdy enough for vertical mounting but would recommend additional support for horizontal installations. The metal housing feels premium and matches the aesthetic of high-end cases.

Ideal for system monitoring enthusiasts

If you constantly check your temps while gaming or working, this screen keeps that information visible without alt-tabbing. I have mine configured to show critical stats at a glance. The display updates smoothly and never impacts system performance. For overclockers and benchmarkers, having real-time data visible is genuinely useful.

Requires software patience

The L-Connect 3 software for this display is functional but needs refinement. Creating custom themes takes time, and the interface is not intuitive. Once everything is configured, it works reliably. Just set aside an evening to get your display exactly how you want it. Future software updates will hopefully streamline the experience.

4. Strimer Wireless 24 Pin with Controller – Cable-Free RGB Control

The Strimer Wireless 24 Pin represents Lian Li pushing the boundaries of what RGB cables can do. By using 2.4 GHz wireless technology, this power extension cable eliminates the need for internal USB connections just to control RGB. I installed this in a recent build, and the reduction in cable clutter behind the motherboard tray was noticeable.

The lighting quality is exceptional. The improved lighting guide provides better side coverage than previous Strimer generations. Colors are accurate and vibrant, matching what you see in L-Connect 3 software. At 315mm long, this cable works well with most PSU and motherboard configurations in larger cases.

The included L-Wireless Controller is required and handles communication between your software and the RGB elements. Once paired, the connection has been rock solid in my testing. No dropped signals or color glitches. The controller can also manage other Lian Li wireless devices, creating a unified ecosystem.

Be warned that the cable itself is quite stiff. Routing it through tight spaces takes patience. The connectors also fit very tightly with some PSU cables, requiring firm pressure to seat properly. These are minor annoyances given how clean the final result looks.

Best for wireless ecosystem builds

If you are investing in Lian Li’s wireless accessories, the Strimer Wireless 24 Pin is the centerpiece. Pair it with wireless UNI FANs and other Strimer Wireless cables for a completely wireless RGB setup. The unified control through L-Connect 3 makes managing everything straightforward once configured.

Premium price for premium features

There is no getting around the cost. This cable costs significantly more than standard RGB extensions. For budget builds, the wired Strimer Plus offers similar lighting at a lower price. But for enthusiasts who value clean builds with minimal cables, the wireless technology justifies the investment.

5. Strimer Plus 24-Pin ARGB – Classic RGB Power Extension

The Strimer Plus 24-Pin brings RGB lighting to the most visible cable in your build. With 120 LEDs embedded in the extension, this cable transforms your 24-pin power connector into a lighting feature. I have used several of these across different builds, and the effect never fails to impress.

The included controller offers 18 preset lighting modes out of the box. You can also sync with motherboard RGB software through the 5V ARGB header. This flexibility means the Strimer Plus works with virtually any RGB ecosystem. I prefer using L-Connect 3 for unified control, but ASUS Aura and MSI Mystic Light work equally well.

Installation is straightforward but requires care. The cable is stiffer than standard ATX cables, so plan your routing accordingly. The LEDs are held in place by small clips that can release if the cable is bent sharply. Take your time during installation to avoid this issue.

For the price, the Strimer Plus delivers excellent value. It costs significantly less than the wireless version while providing similar lighting effects. The trade-off is needing an ARGB header and running additional cables, but that is a reasonable compromise for budget-conscious builders.

Great entry point to Strimer RGB

If you want the Strimer aesthetic without the wireless premium, this is your best option. The lighting effects are nearly identical, and the 18 preset modes cover most use cases. I recommend this for builders who already have RGB headers available and do not mind running a few extra cables.

Handle with care during installation

The most common complaint involves LEDs popping out of their clips. This happens when the cable is bent too aggressively during installation. Route the cable with gentle curves rather than sharp angles. Once installed properly, the Strimer Plus provides reliable service and stunning visuals.

6. GB-001 GPU Anti-Sag Bracket – Simple and Effective Support

GPU sag is a real problem with modern graphics cards. The GB-001 from Lian Li solves this elegantly by mounting directly to your motherboard standoffs. Unlike adjustable arm brackets that sit on the case floor, this design stays completely hidden behind your GPU. I have used this bracket with RTX 3080 and 4080 cards, and it works flawlessly.

The bracket installs in minutes using existing motherboard standoff threads. You can position it in the center or toward the right side depending on your GPU layout. For dual-GPU setups, you can even run two brackets. The design does not block airflow to your card, which is crucial for maintaining temperatures.

Build quality is solid aluminum with a black finish that blends into most builds. The bracket is essentially invisible once installed, which is exactly what you want from a support component. It provides firm support without flex or wobble.

Compatibility is the main consideration. Large motherboard heatsinks or connectors positioned between standoffs can interfere with installation. I recommend checking your motherboard layout before purchasing. The bracket works best when your primary GPU slot is not at the very top of the board.

Perfect for clean builds

If you hate seeing adjustable support arms cluttering up your case floor, the GB-001 is the solution. It disappears behind your GPU while providing the same level of support. I use this in all my builds now, preferring it over visible alternatives.

Check compatibility first

Not every motherboard and GPU combination works with this bracket. Motherboards with large VRM heatsinks or M.2 slots near the GPU area may present challenges. Measure your available standoff space before ordering. For problematic configurations, a traditional adjustable bracket might be necessary.

7. Universal 4-Slots Vertical GPU Kit (VG4-4-V2X) – PCIe 4.0 Value Option

The VG4-4-V2X offers vertical GPU mounting at a more accessible price point than the PCIe 5.0 version. For most users, PCIe 4.0 bandwidth is more than sufficient. This kit supports 16GT/s transfer speeds and is backward compatible with PCIe 3.0 systems. I installed this in a friend’s build with an RTX 3070, and the performance impact was zero.

The toolless adjustment system lets you reposition your GPU horizontally by 65mm and toward the side panel by 30mm. This flexibility helps with both aesthetics and cable management. The premium steel construction handles GPUs up to 4 slots thick without flex.

One advantage of this design is that it leaves room for low-profile PCIe cards below the vertically mounted GPU. If you need sound cards, capture cards, or additional storage controllers, you can still use those slots. This is not possible with some competing vertical mount designs.

The main drawback involves heavier cards. Three-fan GPUs may experience some sag at the front corner despite the solid construction. I recommend pairing this kit with the GB-001 bracket for maximum support with heavier cards. The installation process can also be finicky depending on your motherboard layout.

Excellent value for most builds

If you do not need PCIe 5.0 bandwidth, this kit offers 90 percent of the functionality at a lower price. Most gamers will never saturate PCIe 4.0 bandwidth with current graphics cards. The visual impact of vertical mounting is identical regardless of which riser generation you choose.

Add extra support for heavy cards

For RTX 4080 and heavier cards, consider adding the GB-001 bracket or another support solution. The front corner sag is not dangerous but can bother perfectionists. With additional support, this kit performs on par with much more expensive alternatives.

8. UNI Fan SL-Infinity 120mm Reverse Blade – Optimized for Intake

The reverse blade version of the SL-Infinity addresses a specific need: optimized intake airflow. When mounted as intake fans, the reversed blade orientation reduces turbulence and noise while actually increasing airflow. I tested these as bottom intake fans in my O11 Dynamic EVO, and the difference compared to standard orientation fans was measurable.

With 63.6 CFM at 2100 RPM, these fans move serious air. The infinity mirror design wraps completely around the fan frame, creating that signature multi-layer lighting effect from any viewing angle. Each fan packs 40 LEDs for bright, even illumination.

The daisy-chain system works identically to standard SL-Infinity fans. Connect up to four fans with a single cable for clean installation. The removable keylock and reversible cable module improve compatibility with radiator fittings, which is a thoughtful detail.

Note that single fans do not include a controller. You will need to purchase the SL-Infinity Fan Hub separately or buy a multi-pack that includes one. This ecosystem complexity frustrates some users, so plan your purchase accordingly. Each fan type in the Lian Li lineup requires its specific controller.

Best choice for intake configurations

If you are setting up bottom or side intake fans in your Lian Li case, these reverse blade versions are the better choice. The airflow improvement is real, and noise levels actually decrease compared to standard fans used as intake. I saw a 2-3 degree improvement in GPU temperatures after switching.

Plan your controller purchases

The biggest pain point is the controller situation. Single fans require separate controller purchases, and the controllers are not universal across Lian Li fan types. If you are mixing SL-Infinity standard and reverse blade fans, you can use the same controller. But TL series fans need different controllers entirely.

9. Universal USB and PWM Fan Hub (EG-HUB01B) – Maximum Expansion

The EG-HUB01B solves two problems at once: fan power distribution and USB header expansion. With six 4-pin fan connectors and four USB headers providing eight downstream ports, this hub is perfect for builds running low on motherboard connections. I installed this in a system with eight case fans and multiple ARGB devices, and it handled everything without breaking a sweat.

The 2A per port rating means you can run power-hungry fans without concerns. Color-coded input and output ports make setup straightforward. The hub works with both Lian Li power supplies via their proprietary connector or standard SATA power.

Magnetic mounting lets you stick the hub anywhere inside your case. I placed mine on the power supply shroud for easy access. The magnet holds adequately, though some users wish it was stronger. For permanent installations, the hub also has standard mounting holes.

The build quality feels solid with no flex or cheap components. At this price point, the value proposition is excellent considering the dual functionality. You essentially get a fan hub and USB expansion card in one compact device.

Essential for fan-heavy builds

If you are planning a build with more than six fans or need extra USB headers for RGB controllers, this hub belongs in your parts list. It eliminated the need for splitters and cable adapters in my setup. The clean cable management alone justified the purchase.

Works with any motherboard

Unlike proprietary solutions, this hub is truly universal. Whether you are running ASUS, MSI, Gigabyte, or any other motherboard brand, compatibility is guaranteed. The PWM passthrough means your motherboard still controls fan speeds normally.

10. UNI Fan SL-Infinity Fan Hub Controller – Centralized Fan Management

This fan hub controller is the brain behind the SL-Infinity fan ecosystem. If you buy single SL-Infinity fans rather than multi-packs, you will need this hub to control them. The hub supports up to 16 fans, which covers even the most extreme cooling configurations. I run 12 SL-Infinity fans through one of these hubs, and the centralized control is genuinely convenient.

L-Connect 3 gives you three control modes: Smart Curve, Fixed RPM, or Motherboard PWM Sync. The Smart Curve mode automatically adjusts fan speeds based on temperature readings. I prefer setting custom curves for each fan group, which the software handles easily.

The one-click lighting sync feature ensures all your fans display synchronized effects. This matters when you have fans positioned at different angles around the case. The ARGB signal carries through the daisy-chain without degradation, maintaining color accuracy across all fans.

Compatibility is specific to SL-Infinity 120mm and 140mm non-wireless fans. The documentation could be clearer about 140mm support, which confuses some buyers. This hub does not work with TL series or wireless fans, so verify your fan type before purchasing.

Required for single fan purchases

If you are building your fan setup gradually by buying singles, this controller is not optional. Multi-packs include a controller, but individual fans do not. Factor this cost into your budget when planning your cooling configuration.

Consider your total fan count

With 16-fan capacity, this hub handles virtually any build. But if you only need four to six fans, the controller included with triple-packs may suffice. Plan your fan layout before deciding whether you need this standalone hub.

11. Strimer Wireless 8 Pin (PW8-1W) – GPU Power Cable RGB

The Strimer Wireless 8 Pin extends the wireless RGB ecosystem to your GPU power cables. At 382mm long, this cable accommodates most GPU and PSU configurations. The extended side coverage is specifically designed for RTX 40-series cards, ensuring the RGB strip remains visible even with shrouded GPU designs.

Color accuracy is excellent, matching what you see in L-Connect 3 software precisely. The brightness at maximum settings is genuinely eye-catching. I installed this alongside the 24-pin Strimer Wireless, and the unified control through one wireless controller keeps everything synchronized.

The critical thing to understand is that this cable does not include a controller. You need the L-Wireless Controller, which comes with the 24-pin Strimer Wireless or UNI FAN wireless triple packs. If you already own a wireless controller, this cable integrates seamlessly. If not, budget for the controller as well.

Cable stiffness is the main practical concern. The 382mm length needs careful routing to avoid putting stress on GPU power connectors. Take your time during installation and use cable combs or ties to maintain gentle curves.

Perfect companion to 24-pin Strimer Wireless

If you already have the 24-pin wireless version, adding the 8-pin creates a complete wireless RGB power cable setup. Both cables share one controller, keeping your build clean. The matching aesthetics and synchronized effects make the investment worthwhile for showcase builds.

Remember to buy the controller

Unlike the 24-pin version that includes a controller, this 8-pin cable requires separate purchase of the L-Wireless Controller. Several negative reviews come from buyers who missed this detail. Check your existing Lian Li wireless accessories before ordering.

12. Lancool 216 Dust Filter Kit – Essential Protection

Dust filters are not exciting, but they are essential for long-term system health. The Lancool 216 Dust Filter Kit is specifically designed for the Lian Li Lancool 216 case, fitting perfectly on the intake areas. I added this to my Lancool 216 build, and the reduction in internal dust accumulation has been dramatic.

The magnetic attachment makes installation literally a snap. The filter adheres firmly to the case frame and removes easily for cleaning. No tools required, no permanent modifications. The black finish blends seamlessly with the case aesthetic.

The fine mesh catches dust effectively while maintaining reasonable airflow. I noticed a minimal impact on temperatures, perhaps 1-2 degrees at most. The trade-off for cleaner internals is absolutely worth it. Monthly cleaning takes seconds with the magnetic design.

The biggest complaint from users is that this should have been included with the case originally. Lian Li includes filters on some panels but not others, leading to this aftermarket purchase. The price is reasonable for the quality, but it feels like an essential rather than an accessory.

Must-have for Lancool 216 owners

If you own a Lancool 216, this filter kit should be your first accessory purchase. The case is excellent, but dust ingress is a real issue without these filters. Your components will run cooler and last longer with proper dust protection.

Accept slight RGB dimming

The filter mesh does slightly reduce the visible brightness of RGB fans behind it. The effect is subtle and does not ruin the aesthetic. If you prioritize maximum RGB brightness over dust protection, you might skip this. But for most users, the trade-off strongly favors using the filters.

How to Choose Lian Li Case Accessories

Choosing the right accessories for your Lian Li case depends on several factors. After testing dozens of combinations, I have identified the key considerations that should guide your decisions.

Compatibility by Case Model

Not every accessory works with every Lian Li case. The O11 Dynamic EVO and O11 Dynamic XL support the widest range of accessories, including vertical GPU kits and front mesh panels. The A3-mATX has more limited options due to its smaller footprint. Always check the official compatibility list before purchasing. The Lancool 216 has specific accessories like this dust filter kit that will not fit other cases.

PCIe Generation Matters

For vertical GPU mounting, your choice between PCIe 4.0 and PCIe 5.0 riser cables depends on your graphics card and motherboard. If you are running an RTX 4090 on a Z790 motherboard, the PCIe 5.0 kit makes sense. For mid-range cards or older platforms, PCIe 4.0 offers identical visual results at lower cost. The performance difference is negligible for most users in 2026.

L-Connect 3 Ecosystem Integration

L-Connect 3 is Lian Li’s unified software for controlling RGB and fan speeds. Most modern Lian Li accessories integrate with this software, creating a cohesive control experience. If you plan to run multiple Lian Li products, investing in the ecosystem pays dividends in simplified management. The software has improved significantly over the past year and now offers reliable performance.

Wireless vs Wired Accessories

Lian Li’s wireless accessories eliminate internal cable clutter but come at a premium price. The wireless ecosystem works well once configured, but requires the L-Wireless Controller. Wired alternatives offer similar functionality at lower cost with the trade-off of additional cable routing. For showcase builds where every cable matters, wireless is worth considering. For budget builds, wired accessories provide better value.

Installation Difficulty

Most Lian Li accessories are designed for easy installation, but complexity varies. Fan controllers and simple brackets typically require 15-30 minutes. Vertical GPU kits need 45-60 minutes and careful planning. The 8.8-inch display requires software configuration time beyond physical installation. If you are new to PC building, start with simpler accessories and work up to more complex installations.
