4Pin Molex To 1-to-4 Fan Power Adapter Cable with 5V/12V Speed Reduction

• 1 to 4 Fan Expansion Design

  This cable converts one large 4Pin Molex power connector into four 3Pin/4Pin fan ports, enabling you to power multiple case fans from a single power supply connection. It is ideal for expanding fan setups when motherboard fan headers are limited, supporting up to four fans simultaneously.

  
  

• Two-Speed 5V 12V Control Function

  The cable offers two-speed control with 5V and 12V options. Switching to 5V reduces fan speed for quieter operation and noise reduction, while 12V delivers full speed for maximum airflow. This makes it easy to balance cooling performance and noise levels according to your needs.

  
  

• Stable Power Delivery for Multiple Fans

  Constructed with high-quality copper conductors, this fan hub cable ensures stable power delivery to all connected fans. The multi-port design minimizes voltage drop and maintains consistent performance across all fans, even when powering multiple units at once.

  
  

• Versatile Compatibility with PC Fans

  The adapter works with both 3Pin and 4Pin PWM case fans, supporting voltage control for all standard desktop fans. It is compatible with most Molex-equipped power supplies and common case fans, making it suitable for gaming PCs, quiet home builds, and workstations.

  
  

• Easy Installation and Clean Cable Management

  The plug-and-play design requires no soldering or complex setup, allowing you to quickly connect multiple fans to your power supply. The organized multi-connector layout helps keep cables tidy inside your PC case, contributing to better airflow and a cleaner internal build.

Whether you are building a high-airflow gaming rig, reducing noise in a quiet home PC, or expanding fan connections when motherboard headers are limited, this Molex 4Pin to 3Pin/4Pin 1-to-4 fan hub cable with 5V/12V control provides a convenient, flexible, and cost-effective solution for powering and controlling your case fans.
