Verlengkabel 3-pin Alphacool 18685, 15 cm, 3-pin ventilator-/stroomverlenging

Alphacool Extension Cable 3-pin 18685 is a 15 cm extension cable that preserves the standard 3-pin wiring for signal, power and ground. It is designed to extend the reach of PC fans, temperature sensors and other 3-pin peripherals when original cables are too short, enabling cleaner routing and more flexible component placement inside a computer case.

Advantages

The extension maintains standard 3-pin pinout to ensure compatibility with most PC fans and devices that use a three-wire connection. Its 15 cm length provides moderate additional reach without excess cable slack, which helps keep internal layouts tidy. The cable uses a single, continuous conductor set to preserve signal integrity and reliable power delivery across the extension.

Suitable for

• Extending PC fan cables to reach motherboard or fan hub connectors
• Relocating temperature sensors or small peripherals within a case
• Improving cable management in compact or crowded systems

Key specifications

• Cable type: 3-pin extension for fans/peripherals
• Length: 15 cm
• Conductors: three-wire configuration for signal, +12V power and ground
• Connector style: standard 3-pin female-to-male connectors compatible with PC fans and 3-pin headers
• Use environment: internal computer chassis use

How to use

Connect the male end of the extension to the existing female connector on the motherboard, fan hub or controller, then attach the fan or peripheral to the female end of the extension. Ensure connectors are fully seated and oriented correctly to match the 3-pin pinout so signal, power and ground lines align. Route the cable to avoid sharp bends and pinching points, and secure it with cable ties or clips as needed to prevent interference with moving parts.

Recommendations

Use this 3-pin extension for internal connections only and avoid exposing it to liquids, extreme heat or mechanical damage. For best results, choose an extension length that minimizes slack while allowing the desired component placement; check connector seating after system assembly and occasional maintenance to ensure reliable operation.
