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.
