Cable extension Alphacool 18719 Plastic White 150 mm

The Alphacool 18719 cable extension is an extension lead for 4-pin PWM fans, designed to simplify cable routing and improve airflow inside computer cases. Made from durable plastic with protective sleeving and a white finish, the 150 mm length provides added reach for fan placement and cleaner cable management while maintaining reliable signal transmission for PWM-controlled fans.

Advantages

Protective sleeving increases mechanical stability and helps prevent abrasion, while the plastic construction keeps the cable lightweight. The 4-pin connector preserves PWM functionality for fan speed control. The white color offers a neutral appearance that integrates with many system builds.

Suitable for

• Extending reach of 4-pin PWM case or CPU fans
• Improving cable management and airflow in desktop PCs
• Connecting fans to headers that are slightly out of reach

How to use

Disconnect the fan or system power before installation. Plug the extension cable’s female connector onto the fan’s 4-pin plug, then connect the male connector to the motherboard or fan controller header. Ensure the connectors are fully seated and oriented correctly to preserve proper PWM signal and power delivery. Route the sleeved cable to avoid sharp edges and moving parts.

Recommendations

Use the extension to position fans for optimal airflow and to tidy cable routing; avoid excessive bending or tension and keep the cable away from hot components. Verify compatibility with your fan headers to ensure PWM speed control remains functional.
