Cable extension Alphacool 18724 Plastic White 600 mm

The Alphacool 18724 cable extension is a sleeved 4-pin to 2x 4-pin Y-splitter distribution cable that extends and organizes fan power and PWM signal connections. Made with a protective sleeve over durable conductors and supplied in white plastic, this 600 mm extension helps tidy cable routing and maintain consistent fan control across multiple connectors.

Advantages

The sleeved design provides additional protection against abrasion and improves mechanical stability, which can extend cable lifetime. The Y-splitter lets one 4-pin fan header power and control two separate 4-pin fans, simplifying cable management while preserving PWM signal integrity. The 600 mm length offers flexibility in routing inside various PC cases.

Suitable for

• Connecting two 4-pin PWM fans to a single 4-pin motherboard or controller header
• Extending fan cable reach in mid-tower and full-tower PC cases
• Improving cable appearance and organization in custom builds

How to use

Plug the male 4-pin connector of the extension into the motherboard or fan controller 4-pin header. Connect the two female 4-pin ends to the fans you want to power and control. Ensure connectors are fully seated and that the combined current draw of connected fans does not exceed the specification of the motherboard header or controller. Route the sleeved cable along case channels or tie points to secure it and avoid obstructing airflow or moving parts.

Recommendations

Check the maximum current rating of your motherboard or fan controller header before connecting multiple fans and consult the controller documentation if needed. For optimal cable longevity, avoid sharp bends and keep the sleeved cable clear of hot components.
