Specification: Fan Size: 120mm Origin: Mainland China Certification: CE Fan Life: 100000 hrs Lines: 2 lines Noise: 23dBA Package: Yes Power Interface: 4PIN,5v-3pin ARGB Used For: Radiator,case Fan Speed: 800@1800@rpm Voltage: 12V Model Number: ORION Name: Wireless splicing series building block fan Model: Orion ORION-3 Color: black, white(optional) Quantity: single pack, 3 pack (optional) Wind direction: positive (wind blows toward the back of the fan) Bearing: hydraulic bearing Number of fan blades: 9 Speed: 800~1800 RPM Wind pressure: 2.35mm H2O Air volume: 71CFM Noise: 10~23dBA Power: 4.5W Rated voltage: DC 12V fan; DC 5V lamp beads Rated current: 0.36A ARGB rated current: 0.18A Expected life: 80000H (hours) Fan interface (male and female interface): 4-Pin PWM ARGB interface (male and female interface): 5V 3-Pin Wire length: 500mm Applicable: Used on CPU radiator/Radiator water cooling radiator/host chassis with 120mm fan Size: 120.00x120.00x25.00mm/4.72x4.72x0.98inch Weight: 0.25KG Splicing & Series Connection: 1. Connect the conductive wire module to the fan: Connect the wire board connection and the fan power terminal with a snap, and the contact area will be naturally connected and powered; 2. Connect the fan with a snap: The fan connection surface has corresponding snaps. Connect the snaps correctly and the contact area will be naturally connected and powered; 3. Multiple fans can be connected in series: The fan is powered by the wire board to achieve normal operation, and other fans can continue to be connected at the splicing on the other side of the powered fan to achieve multiple fans in series. Note: If the motherboard supports a 5V 3-pin ARGB interface, you don't need to use an ARGB controller, and you can connect it directly to the motherboard. If it does not support it, the fan alone cannot be used and must be used with an ARGB controller. This fan has a positive wind direction, and the wind blows toward the back of the fan. It is generally suitable for the top and back of the chassis. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 01-02: 1 X Case Fan  1 X Screw Pack 1 X Wire 03-04: 3 X Case Fan  3 X Screw Packs 1 X Wire _x005f_x000D_ 1. Innovative Splicing & Single Wire Connection: The case fan introduces a mortise and tenon structure for effortless assembly, eliminating the clutter of wires with a single connection for a more convenient installation. This design allows for electrical wire modules to snap together, enabling fans to connect side by side and support multiple fan series connections for enhanced airflow. 2. Dual-Sided Infinite Lens Lighting: Featuring a unique multi-line design, the chassis fan boasts lens effects on both sides, offering cool, visible illumination. The infinite mirror design on the sides, based on endless geometric shapes, reveals multiple layers of reflection at the fan's center, creating a captivating visual experience. 3. 5V ARGB Synchronization with Major Motherboards: The case cooler fan supports 5V ARGB interfaces of major motherboards like compatible with ASUS/ MSI/Gigabyte/ASRock, allowing for software-controlled lighting with up to 16.8 million colors. With high-density, high-brightness ARGB LEDs, it displays vibrant, full-color illumination without exposing the LEDs. 4. PWM Intelligent Temperature Control and Noise Reduction: With a 4PIN PWM interface, the wireless splicing cooling fan kit supports motherboard PWM for intelligent temperature control, automatically adjusting fan speed based on CPU temperature. Its hydraulic bearing design and strong magnetic motor drive ensure a longer lifespan, quieter operation, and durability. 5. High Airflow & Efficient Cooling Performance: Combining bionics and fluid dynamics, the pc computer radiator cooler features 9 flow-guiding blades with speeds ranging from 800 to 1800 RPM. Even at full speed, it maintains stability while producing 2.35mm H2O of strong air pressure and 71CFM of airflow, ensuring powerful cooling efficiency.
