1PC 82cm PWM CPU Fan Extension Cable, Mainboard 4 Pin Male to Female Fan Adapter Wire, Computer Chassis 4P Power Connector Cord for CPU Cooler and Case Cooling Fans

This 82cm 4Pin PWM fan extension cable is an ideal wiring accessory for DIY PC assembly and chassis modification. It adopts 4-pin male to female connector design to extend the distance between motherboard fan headers and cooling fans. The cable fully reserves all signal lines to maintain complete PWM speed control function, allowing the mainboard to dynamically adjust fan speed based on component temperature.

Made of high-purity copper conductors, it features low transmission resistance to guarantee stable power supply and signal delivery. Each connector is built with lock buckles for firm insertion, effectively avoiding intermittent power issues caused by vibration. The flexible insulated outer sheath supports various routing layouts to organize messy internal cables, improve chassis air circulation and lower overall operating temperature.

Suitable for most standard 4Pin PWM CPU coolers, case intake fans, exhaust fans and radiator cooling fans. No drivers or extra configuration required, simply plug and play. Perfect for hardware upgrades, large chassis wiring arrangement and custom water cooling system installation.
