The 1 to 5 fan splitter hub expands a single 4pin or 3pin motherboard fan header to power up to five fans. This 5 way hub uses a 5 way 4pin male connector jack and is designed as a plugandplay solution for PC case fans. Key benefits Compatibility with both 4pin PWM and 3pin fans, suitable for PC case and motherboard fan headers. Converts one fan header into five outputs, enabling multiple fans to be powered from a single header. PWM support for 4pin fans, helping you maintain desired cooling by coordinating fan speeds. Simple plugandplay installation, no tools or soldering required. Improves airflow and cooling potential in systems with limited motherboard headers. What this product does Provides a convenient way to run up to five case or radiator fans from a single motherboard fan header. Keeps PWM control available for compatible fans, allowing centralized and adjustable cooling performance. Compatible use scenarios Scenario 1: A gaming or performance PC with several chassis and radiator fans; connect all fans to one header for unified speed control. Scenario 2: A compact build or small form factor system that has few motherboard fan headers; expand to five fans without adding headers. Scenario 3: A test bench or airflow benchmarking setup that requires running multiple fans from a single header for consistent testing conditions.
