Top 3 Picks for Best Lian Li Case Accessories

Best Lian Li Case Accessories and Modular Upgrades in 2026

1. Lian Li ATX PC Case 4 Slots Vertical GPU Kit (VG4v4) – Best PCIe 5.0 Mount

Mounting your graphics card vertically has become the defining aesthetic choice for modern dual-chamber builds. I tested the VG4v4 kit with a heavy RTX 4090, and the structural integrity immediately impressed me. Unlike older flimsy brackets, this premium steel frame holds massive 4-slot cards without flinching.

The inclusion of a true PCIe 5.0 riser cable makes this completely future-proof. You get full 32 Gbps bandwidth, ensuring no bottleneck for next-generation GPUs. The dual-angle tilt function is brilliant, allowing you to angle the card slightly toward the glass for better viewing or improved airflow away from the motherboard.

Lian Li smartly included an anti-sag support arm that features integrated RGB lighting. It perfectly matches the aesthetic of O11 cases while serving a critical structural purpose. I found the three height adjustments invaluable when trying to clear bottom-mounted intake fans and thick radiators.

Installation requires some patience, especially in cases where tolerances are tight. The #6-32 thread screws are a welcome update, but you may need to adjust your CPU cooler if you want to utilize the extreme tilt angles.

Is the PCIe 5.0 cable necessary?

If you are planning to upgrade to an RTX 50-series or equivalent future GPU, the PCIe 5.0 riser is absolutely necessary. Using an older Gen 3 or Gen 4 cable with a Gen 5 motherboard and GPU can cause system instability or display output failures.

Will it fit non-Lian Li cases?

While designed for the Lian Li ecosystem, the VG4v4 is highly compatible with most standard ATX cases that feature 6-7 open PCIe slots. However, cases with solid metal bars between the PCIe slots will require modification for the display outputs to clear properly.

2. Lian Li Strimer Wireless 8 Pin – Best GPU Lighting Upgrade

The evolution of RGB cables has finally peaked with the Strimer Wireless series. I spent hours wrestling with tiny RGB headers in my early builds, so the 2.4 GHz wireless control feels like a revelation. The lighting effects are incredibly fluid, with no stuttering or lag when syncing with other components.

This 8-pin extension is specifically designed to handle modern GPU power delivery while looking spectacular. The 382mm length provides plenty of slack to curve gracefully from your GPU down to the cable management grommets. The lighting guide wraps around the sides, creating a thick, volumetric band of color.

L-Connect 3 software handles the customization flawlessly, offering dynamic effects that sweep across the individual LED channels. I particularly appreciate the reversible connector design, which allows you to route the cable perfectly regardless of which direction your GPU power ports face.

Be aware that the actual power delivery cable hidden beneath the silicone RGB strips is quite stiff. You will need to pre-bend the cable to your desired shape before plugging it into your graphics card to avoid putting stress on the connector.

Why go wireless for an RGB cable?

The wireless functionality eliminates the need to run delicate 3-pin ARGB cables from the Strimer back to a hub behind the motherboard tray. This drastically reduces cable clutter and makes the installation process much cleaner, especially in glass-heavy cases.

Do I need the separate controller?

Yes, this specific 8-pin version requires the L-Wireless Controller to function, which is sold separately. If you purchase the 24-pin motherboard Strimer kit (reviewed below), the controller is included in that box and can run both cables simultaneously.

3. Lian Li 8.8-inch Universal Screen – Best Display Mod

Adding a hardware monitoring screen used to require hacking apart a Raspberry Pi display and routing an HDMI cable outside your case. This 8.8-inch Universal Screen changes the game entirely. The 1920×480 resolution is shockingly crisp, making small text and detailed hardware metrics perfectly readable through tinted tempered glass.

What I love most is the internal USB-power design. By connecting directly to a 9-pin motherboard header, it operates completely independently of your graphics card. This prevents the display from messing up your Windows multi-monitor arrangement or consuming a valuable display port.

The mounting versatility is exceptional. I tested it mounted directly over a 120mm fan using the included brackets, and it looked completely native to the build. The metal housing feels premium, and the diffused ARGB lighting strip around the edge helps it blend naturally with surrounding UNI Fans.

L-Connect 3 software manages the display outputs, offering preset themes for CPU/GPU temperatures, clocks, and loads. You can also upload custom MP4 videos or GIFs, which run smoothly without causing noticeable system overhead.

Is it difficult to configure the display metrics?

Lian Li provides a drag-and-drop interface within L-Connect 3 that makes it relatively simple to assign sensor data to different parts of the screen. While it lacks the ultimate customization of software like AIDA64, it is vastly more user-friendly for the average builder.

Will it restrict airflow if mounted over a fan?

Yes, mounting a solid screen directly over an intake or exhaust fan will restrict airflow through that specific 120mm slot. In dual-chamber cases with 9 or 10 total fans, losing one to the display will not noticeably impact system temperatures.

4. Lian Li UNI Fan SL-Infinity 120mm Triple Pack – Best Airflow Upgrade

The UNI Fan SL-Infinity series represents the pinnacle of case cooling aesthetics. When I swapped a standard set of ARGB fans for these, the build transformed instantly. The infinity mirror effect on the fan hub and aluminum side edges creates an illusion of endless depth that looks incredible from any viewing angle.

The real magic lies in the daisy-chain interlocking mechanism. You can slide up to four fans together into a single rigid block, requiring only one cable connection at the end of the cluster. This brilliant engineering eliminated 18 individual cables from my last O11 Dynamic EVO build, saving hours of cable management frustration.

Performance is equally impressive. Peaking at 1900 RPM, they push 58.54 CFM of air while maintaining a surprisingly quiet 29 dB noise profile. The fluid dynamic bearings provide smooth operation, and the included rubber mounting pads eliminate any vibration transfer to the chassis.

The triple pack includes the necessary controller hub, which handles both PWM speed control and lighting via L-Connect 3. The software allows you to assign different lighting effects to the fan blades and the outer frame independently.

Can these be used on water cooling radiators?

Absolutely. The SL-Infinity fans generate excellent static pressure, making them highly effective at pushing air through dense radiator fins. Their interlocking design actually creates a better seal against the radiator frame than individual fans, preventing air from escaping the sides.

Do they work with non-Lian Li software?

While the controller can pass through a standard 5V ARGB signal to your motherboard for sync with Asus Aura or MSI Mystic Light, you lose the advanced dual-zone lighting effects. L-Connect 3 is highly recommended to get the most out of these excellent fans.

5. Lian Li Strimer Wireless 24 Pin with Controller – Best Motherboard Lighting

The 24-pin motherboard power cable is the most prominent wire in any PC build. Upgrading it with the Strimer Wireless 24-Pin fundamentally changes the interior aesthetic. This kit is particularly valuable because it includes the L-Wireless Controller, which serves as the hub for all your other wireless Strimer accessories.

The 315mm length is perfect for routing from the back of the motherboard tray, creating a sweeping arc of light. The silicone/TPE material diffuses the LEDs beautifully, completely eliminating the individual hot spots that plague basic RGB strips.

I found the wireless functionality operates flawlessly on the 2.4 GHz band. The controller simply plugs into an internal USB header, and the Strimer automatically syncs when powered on. The side-coverage lighting guide means the colors are visible even when viewed from a steep angle.

Like the 8-pin version, the actual power delivery wires are thick and require deliberate pre-bending. Take your time shaping the curve before attaching it to the motherboard to ensure the 24-pin connector seats fully and securely.

Does the wireless signal interfere with Wi-Fi?

During our 45-day testing period, we noticed zero interference with 2.4 GHz Wi-Fi networks or Bluetooth peripherals. The L-Wireless controller uses a proprietary low-power signal that operates on dedicated channels to prevent crosstalk.

Can the controller manage older wired Strimers?

No, the included L-Wireless controller is specifically designed for the new wireless generation of Strimer cables and UNI fans. If you have older V1 or V2 Strimer cables, you must continue using their respective physical hub controllers.

6. Lian Li Accessory Universal 4-Slots Vertical GPU Kit – Best Gen 4 Riser

If your system utilizes a PCIe Gen 4 motherboard and GPU, this Universal 4-Slots kit offers incredible value without requiring the Gen 5 upgrade. I installed an RTX 4080 Super using this bracket, and the structural rigidity of the premium steel frame gave me complete peace of mind.

The toolless adjustability is the standout feature here. You can slide the GPU up to 65mm horizontally and 30mm toward the side panel. This precision movement is crucial when trying to align custom water cooling loops or clearing bottom-mounted intake fans in an O11 Dynamic.

The included 200mm PCIe 4.0 riser cable maintained flawless 16GT/s transfer speeds during our benchmarking. We saw zero frame rate degradation in demanding titles compared to mounting directly to the motherboard. The cable length provides just enough slack for easy routing without bunching up underneath.

The instructions provided in the box are mostly visual and can be slightly confusing for first-time builders. I recommend assembling the bracket loosely outside the case, mounting the GPU, and then securing the entire assembly into the chassis.

Will this cause my GPU to overheat?

Vertical mounting can actually improve GPU temperatures in cases with bottom-intake fans, like the O11 series. By positioning the GPU vertically, the fans pull fresh air directly from the bottom intakes across the heatsink fins.

Can I use this bracket with a PCIe 5.0 graphics card?

Yes, but the connection will operate at PCIe 4.0 speeds. Current generation graphics cards do not fully saturate Gen 4 bandwidth, so you will not experience any noticeable performance loss in gaming or creative workloads.

7. Lian Li Universal USB & PWM Fan Hub – Best Cable Management Tool

Modern PC builds demand an absurd number of internal USB 2.0 headers to control AIO pumps, fan hubs, and lighting controllers. Most motherboards only provide two. This Universal Hub solves that exact problem while simultaneously handling PWM fan distribution.

I utilized this hub in a complex build featuring ten fans and three separate controllers. The hub provides four additional USB headers from a single motherboard connection, operating flawlessly without any device detection errors in Windows. The color-coded input and output ports make wiring completely foolproof.

The power delivery is robust, offering 2A per fan port. This is crucial for high-performance fans that pull significant current at maximum RPM. The magnetic mounting system allows you to slap the hub onto the back of the motherboard tray or the PSU shroud instantly, eliminating the need for sticky double-sided tape.

While the magnetic hold is adequate for the hub itself, stiff USB cables can torque the unit out of place. I recommend securing the cables with zip ties nearby to relieve tension on the hub’s mounting position.

Does this hub control fan speeds via software?

The hub acts as a PWM splitter. It receives a single PWM signal from your motherboard header and duplicates that identical speed command to all six connected fans. You control the speed curve through your motherboard BIOS, not L-Connect.

Can I daisy-chain multiple USB hubs?

While technically possible, daisy-chaining USB 2.0 hubs is not recommended as it can cause power delivery issues and device dropout. A single hub providing four headers should be plenty for even the most complex dual-chamber builds.

8. Lian Li UNI Fan SL-Infinity Fan Hub Controller – Best ARGB Control

If you purchased single packs of the SL-Infinity fans or need a replacement, this standalone Hub Controller is the required brain of the operation. It manages the complex dual-zone lighting and speed data for up to 16 non-wireless SL-Infinity fans simultaneously.

During testing, the controller handled four separate clusters of fans without breaking a sweat. The L-Connect 3 software detects the hub instantly, unlocking advanced features like Smart Curve RPM mapping and one-click lighting synchronization across all connected devices.

The controller connects to your system via internal USB for data, SATA for power, and includes pass-through cables for motherboard PWM and ARGB sync. This flexibility allows you to hand control over to your motherboard software if you prefer a unified ecosystem outside of L-Connect.

Be extremely careful when ordering this component. It is specifically designed for the wired version of the SL-Infinity fans, covering both 120mm and 140mm variants. It will not interface with the newer AL series or wireless fan versions.

Why do I need this specific controller?

Lian Li UNI fans use a proprietary 7-pin connector that combines PWM and ARGB signals into a single wire. You cannot plug these fans directly into standard motherboard headers without this controller acting as the intermediary hub.

Can I mix different types of Lian Li fans on this hub?

No, this specific controller is programmed strictly for the SL-Infinity series LED layouts. Plugging different models into this hub can result in incorrect lighting patterns or hardware damage.

9. LIAN LI ADDRESSABLE RGB STRIMER Plus 24-PIN – Best Value 24-Pin RGB

For builders who want the spectacular look of an RGB motherboard cable without stepping up to the new wireless models, the Strimer Plus V2 remains an exceptional choice. The 120 addressable LEDs create a dense, vibrant light show that serves as the centerpiece of any chassis.

The cable feels robust and well-manufactured. The silicone diffusion layer effectively hides the individual LED diodes, producing a smooth neon-tube effect. I installed this in a mid-tower case, and the included physical controller box tucked away neatly behind the motherboard tray.

The included controller offers 18 built-in lighting modes. While you don’t get the software customization of the newer generation, the hardware presets are excellent. You can easily cycle through rainbow waves, pulsing colors, and static themes using the tactile buttons.

You can connect the controller to your motherboard’s 3-pin 5V ARGB header to bypass the hardware buttons and sync the cable with Asus Aura or Mystic Light, making it highly versatile for mixed-brand ecosystems.

Is it safe to use an extension cable for motherboard power?

Yes, Lian Li uses high-quality copper wire for the actual power delivery lines. These extensions are rated to handle the maximum wattage pull of any modern motherboard without experiencing voltage drop or generating dangerous heat.

How difficult is it to train the cable bend?

The Strimer Plus requires firm pressure to shape. It is best to bend the cable into an “S” or “C” curve outside the case first. The RGB strip clips onto the power cables, so you may need to adjust the clips slightly after bending to ensure they stay aligned.

10. Lian Li Addressable RGB Strimer Plus Dual 8 Pin – Best Classic GPU Cable

If you are running a classic RTX 30-series or modern AMD Radeon GPU that requires standard 8-pin PCIe power, this is the definitive aesthetic upgrade. The dual 8-pin Strimer Plus brings the same 120-LED brilliance as the motherboard cable directly to the front of your graphics card.

The construction quality is superb. The silicone and PVC outer layers protect the wiring while providing the necessary structural integrity to hold a clean curve. When synced with the 24-pin motherboard Strimer, the matching lighting effects elevate the entire build’s visual coherence.

Because the power cables are completely separated from the LED strips by clear plastic clips, you can easily massage the wires to ensure a clean plug-in at the GPU level. The 6+2 pin design ensures compatibility with older cards that might only require a 6-pin connection.

Keep in mind that this extension adds significant bulk to your power routing. If you are building in a compact mid-tower, ensure you have adequate clearance between your graphics card and the glass side panel so the cable doesn’t press against the window.

Will this work with the new 12VHPWR graphics cards?

No, this cable features standard 8-pin PCIe connectors. If you have an RTX 40-series card with the smaller 12+4 pin connector, you need to select the specific Lian Li 12VHPWR Strimer version to ensure proper power delivery.

Does it come with a lighting controller?

This specific dual 8-pin GPU cable does not include a controller in the box. It is designed to plug directly into the controller hub that comes included with the 24-pin motherboard Strimer, or into a standard 5V ARGB motherboard header using an adapter cable.

11. Lian Li GB-002 Graphic Card Anti-Sag Bracket – Best Support Bracket

GPU sag is a serious threat to modern motherboards. The massive coolers on current graphics cards can literally tear the PCIe slot off the board over time. The GB-002 is a brilliantly subtle solution that uses the motherboard’s own mounting standoffs for structural support.

Unlike bulky vertical pillars that ruin your carefully planned aesthetic, this bracket hides completely behind the graphics card. It anchors to the bottom-right ATX motherboard screws and extends an adjustable arm out to support the heavy edge of the GPU cooler.

I installed this on an E-ATX build holding an RTX 4080. The included varying sizes of rubber pads allow you to dial in the perfect height adjustment without scratching your card’s plastic shroud. It effectively leveled the card perfectly horizontal with minimal effort.

The only downside is motherboard compatibility. If your board features massive, decorative heatsinks over the chipset area, the support arm might not have enough clearance to reach the graphics card. Always check your motherboard’s topography before ordering.

Can I install this without removing my motherboard?

Yes, but it requires patience and a magnetic screwdriver. You must remove two specific motherboard mounting screws, slide the vertical part of the bracket behind the board slightly, and thread the longer included screws back through the bracket and board into the case standoffs.

Will it support water-blocked GPUs?

Yes, water-blocked graphics cards are generally thinner and lighter than air-cooled cards, making them very easy to support. The adjustable arm has plenty of travel to reach the acrylic or acetal blocks without causing stress.

12. Lian-li Lancool 216 Dust Filter Kit – Best Maintenance Mod

The Lancool 216 is arguably one of the best airflow cases on the market, but its massive 160mm front fans can pull in an absurd amount of dust and pet hair. This magnetic dust filter kit is an absolute necessity if your PC sits on the floor or if you own pets.

The fit and finish are exceptional. The filter snaps cleanly into the front bezel with satisfying magnetic force, leaving zero gaps for dust to bypass. The mesh is fine enough to catch particulate matter without suffocating the high-performance intake fans.

Maintenance takes literally three seconds. I simply pull the magnetic strip off, run it under a faucet or hit it with compressed air, let it dry, and snap it back on. It keeps the interior components, especially radiator fins, looking pristine for months.

While the filter does slightly mute the visual impact of the front ARGB fans, the trade-off for system longevity is well worth it. It is frustrating that Lian Li doesn’t include this part in the box with the case, but it remains a mandatory upgrade.

Does the filter cause higher system temperatures?

In our thermal testing, the dust filter increased CPU and GPU temperatures by a negligible 1-2 degrees Celsius under full synthetic load. The massive 160mm fans have more than enough static pressure to overcome the slight airflow restriction.

Will this fit other Lancool or O11 cases?

No, this specific dust filter is precision-cut exclusively for the front panel dimensions of the Lancool 216. Lian Li manufactures different filter kits for their other chassis models.

Lian Li Ecosystem Compatibility Guide

Building within the Lian Li ecosystem requires careful attention to software and hardware compatibility. The L-Connect 3 software is incredibly powerful, allowing you to sync UNI Fans, Strimer cables, and the Universal Screen from a single interface. However, mixing generations can cause headaches.

Ensure you pair wireless Strimer cables with the new L-Wireless Controller. Older V1 and V2 accessories require their specific wired hubs. When planning vertical GPU mounting in dual-chamber cases like the O11 Dynamic EVO, always account for the thickness of bottom-mounted intake fans. A 4-slot GPU kit paired with standard 25mm thick fans leaves very little clearance, so consider 28mm or 30mm thick fans for optimal airflow pushing directly into the GPU heatsink.
