✅ Authorized Lian Li Partner in Egypt | Official Warranty Coverage | Expert PC Building Consultation Available

⚡ Engineering Highlights at a Glance:

• Standard Blade Design: Pushes air through the back, making the rear visible. Suitable for exhaust and radiator configurations.
• Dual-Zone RGB Lighting: Independent control of the fan blades and side light strips creates layered illumination with a clean yet expressive look.
• Interlocking Design: Links multiple UNI Fan CL Flex fans into one aligned group for easier installation and cleaner cable management.
• FLEX Receiver: Integrates power, RPM reporting, fan-speed, and lighting control into one compact module.
• L-Wireless Ecosystem: Unified control of up to 10 channels of compatible Lian Li devices through L-Connect 3.
• Dual Control Modes: Choose between L-Connect 3 or motherboard PWM/5V 3-pin ARGB sync.
• Aluminum-Style Center Nameplate: Creates a refined focal point that elevates the clean RGB design.
• FDB Bearing: Delivers up to 2100 RPM, 77.34 CFM airflow, and 29.8 dBA noise level for reliable cooling.

Standard Blade vs Reverse Blade

Standard blade fans push air through the back, making the rear visible. They are ideal for rear exhaust, top exhaust, and radiator push configurations. Reverse blade fans are designed for intake configurations where the front face is visible from inside the case. Choose standard blade when the fan’s primary function is exhaust or when the rear of the fan will be hidden.

🔧 Control Modes and Setup

The UNI Fan CL Flex supports two control modes: L-Connect 3 via L-Wireless (2.4GHz) and motherboard sync via 4-pin PWM and 5V 3-pin ARGB cables. Use L-Connect 3 to access custom device naming, fan grouping, fan curves, and advanced lighting effects. When the wireless receiver is connected and bound in L-Connect 3, users can freely switch between motherboard sync and L-Wireless lighting control. Motherboard sync can be used without L-Connect 3 for a simpler setup.

📐 Fan Grouping and Expansion

Each FLEX Receiver supports up to 4 matching UNI Fan CL Flex fans for simple and organized fan group expansion. For optimal RPM accuracy, group fans with the same blade orientation on each receiver. The interlocking clip design links multiple fans into one aligned group for easier installation and cleaner cable management. Daisy-chain the fans to reduce cable clutter, and use the included 1-to-3 PWM to SATA cable for power delivery.

For the cleanest build, use the interlocking clip design to link the three UNI Fan CL Flex fans into one aligned group. Connect the FLEX Receiver for power and control, and use the included 1-to-3 PWM to SATA cable for power delivery and the 5V 3-pin ARGB cable for motherboard sync if you prefer not to use L-Connect 3. If you want advanced control, install L-Connect 3 and bind the L-Wireless Controller to access custom device naming, fan grouping, fan curves, and lighting effects. Standard blade fans are ideal for rear exhaust, top exhaust, and radiator push configurations. Group fans with the same blade orientation on each FLEX Receiver for optimal RPM accuracy. For quiet operation, set fan curves to keep speeds below 1500 RPM under typical loads, or use the 0 RPM mode for silent operation at low temperatures. The 3-year warranty on both fan and receiver provides long-term peace of mind.
