Product Description

This braided 4Pin fan connector cable is designed to extend or relocate cooling fans while keeping wiring clean and protected. A 4Pin female housing on one end mates to the fan, while a right-angle 4Pin male plug connects to the motherboard or fan hub header. The assembly carries both 12 V power and the tach / PWM control signals, allowing precise fan speed regulation without loss of functionality.

Stranded copper cores and tightly twisted conductors provide reliable signal transmission and stable current delivery to the fan terminals. The entire harness is wrapped in a black PET braided sleeve that resists abrasion, improves airflow and enhances the appearance of high-end builds. This compact wire cable is suitable for desktop systems, gaming rigs, 1U/2U server chassis and embedded electronic equipment where neat, robust cooling connections are required. OEM harnesses can integrate different fan connectors, additional pins or mixed power / control cables for special automotive electronics and industrial controllers.

Applications

Extending CPU or case fan reach to hidden fan hubs or rear PCB headers in desktop and gaming PCs

Organizing fan wiring in rack-mount servers and network equipment for improved airflow and serviceability

Cooling solutions in industrial control cabinets, 3D printers and other electronic enclosures using standard 4Pin fan headers

Custom LED or sensor modules that reuse 4Pin fan style connectors for combined low-current power and feedback signals

Prototype and small-batch projects requiring tailored fan harnesses with specific length, routing and connector combinations

Precautions

Verify that the 4Pin layout (12 V / GND / tach / PWM) matches the header and fan scheme used in the target system before connection.

Avoid exceeding the specified current rating; high-power blower fans may require heavier gauge wire or separate power cables.

Do not sharply bend the cable near the over-molded ends to protect the crimped terminals and maintain stable signal quality.

Keep the harness away from sharp metal edges and hot components inside the chassis to prevent jacket damage.

For larger projects, multi-fan harnesses, different pitch fan connectors, or combined fan-plus-LED wiring looms can be produced to match your mechanical design.
