Designed to simplify control of multiple system fans from a single header Key features Black sleeved 4way PWM splitter hub for computer fans Expands one motherboard PWM fan header to support up to four fans Compact, easytoinstall design suitable for most PC builds Flexible PWM control enables synchronized fan speeds across all connected fans Neat, durable cable construction with a clean, professional appearance Benefits and applications Centralized cooling management: control up to four fans from one motherboard PWM header, reducing the number of headers you need to use Consistent airflow: synchronized PWM control helps maintain stable cooling performance and noise levels Cable organization: black sleeved wiring provides a tidy look and helps reduce cable clutter inside the PC Easy integration: plugandplay compatibility with standard motherboard PWM fan headers Specifications and compatibility Type: 4pin PWM splitter hub Color/material: black sleeved cables Input: 1 motherboard PWM fan header Outputs: up to 4 PWM fan connections Compatibility: designed for standard motherboard PWM fan headers used by computer fans Use scenarios Scenario 1: A mid to performance PC build with multiple intake and exhaust fans, where header availability is limited and you want coordinated speed control. Scenario 2: A compact or small form factor build with restricted space and few fan headers, requiring an efficient way to drive several fans from a single header. Scenario 3: A system where reduced fan noise is important; use the splitter to synchronize fan speeds for quieter operation during lowload tasks. This product provides a practical, reliable solution for expanding a single PWM fan header to support up to four fans, with a focus on function, compatibility, build quality, and performance.
