Extension de câble Alphacool 18721 plastique blanc 600 mm

The Alphacool 18721 cable extension is a 600 mm long white plastic extension for 4-pin PWM fan connectors. It extends the reach of fan cables to improve cable management and airflow inside PC cases. The sleeving around the cable adds protection, increases stability and helps extend the service life of the cable.

Advantages

The sleeved construction provides extra mechanical protection and reduces wear on the conductor. A 600 mm length offers flexibility when routing fan cables in larger cases. The white plastic finish maintains a clean aesthetic and is compatible with systems where visible cable color coordination is required.

Suitable for

• Extending 4-pin PWM fan cables inside desktop PC cases
• Improving cable routing and airflow management
• Systems requiring a 600 mm fan extension or white cable color

Key specifications

How to use

Disconnect the fan and controller or motherboard header before installation. Plug the male end of the extension into the motherboard or fan controller header and connect the original fan plug to the female end of the extension. Ensure the connector orientation matches the 4-pin PWM pinout to preserve speed control and tachometer signal. Route the sleeved cable along case cable channels or tie-down points to avoid interference with fans and moving parts.

Recommendations

Use the extension only for 4-pin PWM fan connections; avoid forcing connectors or bending the cable sharply. Check the connectors and cable for damage before use and replace the extension if sleeving or insulation is compromised.
