1PC 42cm PWM CPU Fan Extension Cable, Mainboard 4 Pin Male to Female Fan Adapter Wire, Computer Case 4P Power Connector Cord for CPU Cooler & Chassis Cooling Fans

This 42cm 4Pin PWM fan extension cable is specially designed for DIY computer assembly, which effectively extends the connection distance between motherboard fan headers and cooling fans. It adopts male to female 4Pin connector design and completely reserves the PWM speed control signal line, enabling your motherboard to automatically adjust fan rotation speed according to CPU temperature without losing speed regulation function.

Constructed with high-purity copper inner conductors, the cable features low resistance and stable power and signal transmission. Each connector comes with built-in locking buckles to form tight connections and prevent loose contacts caused by vibration during long-term operation. The soft and bendable outer insulation sleeve supports flexible wiring arrangement, helping organize messy internal cables and optimize chassis airflow to reduce operating temperature.

Widely applicable to all standard 4Pin PWM CPU coolers, case intake/exhaust fans, radiator fans and other computer cooling equipment. No driver or complicated installation steps required, simply plug and play. An essential practical accessory for PC builders, hardware upgrade and chassis cable management modification.
