1. Improving Airflow: -to-many PWM Power Multi Splitter has beautiful all black sleeve cables, which can improve airflow and confusion and clutter. 2. Purpose: Fan PWM Splitter is suitable for situations where the CPU fan plug (4Pin) is not long enough or is not used enough, and the four pins of the chassis fan are not long enough. It mainly extends and expands the motherboard's four pin interface. 3. Scope of Application: The Extension Cable Connector splits a 4-pin female head into multiple 4-pin male heads, suitable for CPU or computer chassis fans. 4. Speed Measurement Function: The PWM Adapter Cable is equipped with a speed measurement function. Since a main board power supply socket can only detect one fan speed, if other interfaces have speed measurement cables, different fan speeds can cause inaccurate speed measurement. Therefore, the first interface is equipped with a speed measurement function, and other interfaces do not. 5. Exquisite Size: Pwm Fan Cable has simple and generous design, small size, light weight, simple installation, easy to get a experience. Specification: Type: PWM Cable Model Number: PWM Splitter Product weight: about 23g Wire model: 1007 22AWG Interface: computer motherboard 3Pin/4Pin interface Function: Make five computer fans share a 3Pin/4Pin interface Usage: CPU fan plug (4Pin) is not long enough, insufficient use, chassis fan four pins are not long enough, and so on. Mainly for extending and expanding the motherboard four-pin interface Material: pvc colour: black Package Contents: 1 set x 5 fan temperature control extension cords (1 minute 3) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
