SMT patching process with full solder joints for reliable, durable connections. 5Port PC Fan Hub Splitter with PWM speed controller for 4pin PWM fans, enabling centralized control of multiple case fans. Newly designed circuit and wiring engineered to handle higher current for stable performance under load. 1u sinking gold process with goldplated contacts for higher flatness and a cleaner, more durable appearance. Compatibility and use: supports 4pin PWM PC fans; designed to connect five fans from a single source, reducing motherboard header load and simplifying cable management. Key benefits: centralized fan control from one hub, improved electrical reliability, better signal integrity from goldplated contacts, and enhanced overall cooling performance. Use scenarios: Gaming PC builds with multiple case fans for optimized cooling and quieter operation through centralized PWM control. Small form factor or motherboardheaderlimited systems where five fans need power and speed regulation from a single hub. Workstations or rendering rigs requiring consistent airflow and synchronized or individually adjustable fan speeds for longduration workloads.
