Specification: Origin: Mainland China Color: White Length: About 75cm/29.5in Product weight: About 23g Wire model: 1007 22AWG Insulation material: PVC insulation Conductor material; Tinned copper Interface: Computer motherboard 3Pin/4Pin interface Function: Enable five computer fans to share a 3Pin/4Pin interface Usage: CPU fan plug (4Pin) is not long enough, in case of insufficient use, and the four pins of the chassis fan are not long enough, etc. Mainly extending and expanding the motherboard's four pin interface Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1 x PWM Splitter 1. Improving Airflow: The one-to-many PWM Power Multi Splitter has beautiful all black sleeve cables, which can improve airflow and eliminate 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.
