Ease of Use Enables water cooling RGB and fan sensor integration through a 19pin to double 9pin design, providing USB 2.0 expansion to connect multiple devices and ensuring compatibility with a wide range of mainstream motherboards. Consistent Data Maintenance Uses durable conductive materials to ensure consistent data transmission for dependable RGB control and precise fan speed monitoring, enhancing overall device performance. Broad Application This 19pin USB 3.0 header supports plugandplay setup with RGB fans and water cooling devices, and fits motherboards with 19pin ports for enhanced convenience and performance. SpaceSaving Design Splits one 19pin input into two 9pin outputs to support RGB and fan device connections, improving internal layout efficiency with flexible splitting options that maximize hardware compatibility. Use scenarios Gaming PC with a water cooling loop and multiple RGB fans: centralizes RGB control and sensor monitoring on a single header for cleaner cable management and reliable performance. Compact or miniITX builds: provides USB 2.0 expansion and RGB/fan connections when motherboard headers are limited, aiding tidy installation without driver requirements. Workstation or contentcreation rig: supports several RGB devices and cooling sensors through a single, plugandplay header, reducing setup complexity and maintaining precise fan speed monitoring.
