Extra-Long 480mm Flexible Tubing Architecture
The Lian Li Galahad II LCD 360 SL-INF liquid cooler is specifically designed for modern dual-chamber enclosures. A standout engineering feature is its extended 480mm flexible sleeved tubing. Standard AIO liquid coolers on the market typically include 380mm to 400mm tubes. The extra 80mm to 100mm of tube length provided by Lian Li solves severe routing challenges encountered when mounting 360mm radiators in side-intake or side-exhaust wall configurations within large dual-chamber cases like the Lian Li O11 Dynamic EVO, O11 Vision, or NZXT H9 Flow.
Side-Mount Tubing-Down Orientation & Fluid Dynamics
From a liquid cooling acoustics and pump longevity perspective, the optimal orientation for a side-mounted radiator is tubing at the bottom (tubing-down). Placing the radiator end-caps with the hose inlets at the lowest point ensures that naturally occurring air bubbles collect in the top end-cap of the radiator, preventing air ingestion into the pump block and eliminating gurgling noise.
However, achieving a tubing-down side-mount configuration with standard 400mm AIO tubes is often impossible when pairing with long high-end GPUs:
- Tube Stretching: Standard 400mm tubes must span across the length of a 300mm+ graphics card and reach up to the CPU socket. This causes the tubes to stretch taut across the sharp metallic backplate of the GPU.
- The 480mm Solution: The Galahad II LCD’s 480mm tubing comfortably arches down from the radiator base, sweeping neatly beneath or around oversized graphics cards—such as an RTX 4090 PCIe slot clearance build—without applying strain to the pump fittings or GPU PCB.
Tubing Length & Chassis Mounting Comparison
| AIO Cooler Model | Stock Tubing Length | Side-Mount Tubing-Down Capability (with 340mm GPU) |
|---|---|---|
| Lian Li Galahad II LCD 360 | 480 mm | Flawless (Comfortable arch under GPU) |
| Corsair H150i iCUE Link | 400 mm | Taut (Stretches across GPU backplate) |
| NZXT Kraken Elite 360 | 400 mm | Taut (Requires tubing-up compromise) |
| ARCTIC Liquid Freezer III 360 | 450 mm | Good (Slight tension over wide cards) |
Pump Block Fitting Articulation & Cable Routing Clearance
The pump block of the Galahad II LCD features 45-degree rotary fittings that swivel 360 degrees. This articulation allows clean routing paths in dual-chamber chassis, avoiding clearance issues with upper motherboard cable cutouts outlined in GIGABYTE Z790 AORUS Master E-ATX PSU shroud cable grommets guides.
Furthermore, builders can pair this setup with high-end power supplies like a be quiet! Dark Power 13 1000W ATX3 unit, knowing that side-chamber cable management spaces remain uncluttered and airflow paths through the side radiator bracket remain completely uninhibited, as detailed in Lian Li O11 Dynamic EVO AIO clearance documentation.
SL-INF Daisy-Chain Fan Hub Interconnects
The SL-INF edition comes pre-installed with Lian Li Uni Fan SL-Infinity fans that slide and lock together using modular pin contact keys. This reduces radiator fan wiring down to a single short cable harness that plugs directly into the Lian Li L-Connect 3 hub. When side-mounting, bundle the fan interconnect cable along the rear edge of the radiator bracket to avoid interference with side glass panel latches.
Veteran Builder Installation Checklist & Diagnostic Protocol
Maximizing the reach of the 480mm tubing on the Lian Li Galahad II LCD 360 SL-INF requires systematic cable and tube routing:
- Position Radiator Tubes Downward: Mount the 360mm radiator on the side intake wall with the hose inlets at the bottom. The 480mm tube length will comfortably sweep under graphics cards up to 350mm long.
- Articulate 45-Degree Pump Fittings: Swivel the 45-degree rotary fittings on the pump block upward to guide the tubes in a smooth natural arc towards the side radiator base.
- L-Connect 3 Hub Configuration: Connect the SL-INF fan stack single-cable harness to Port 1 on the L-Connect 3 controller. Connect the controller’s SATA power leads to a primary PSU SATA cable harness.
- Screen Telemetry Calibration: Open L-Connect 3 software, navigate to the Display tab, and configure real-time CPU temp, GPU temp, and liquid temp sensors on the 2.1-inch LCD screen.
