Cable extension Alphacool 18720 Plastic White 300 mm

The Alphacool 18720 cable extension is a 300 mm white plastic extension for 4-pin PWM fan connectors. It is intended to extend fan cabling and improve cable management inside PC cases, providing a neat appearance and allowing more flexible fan placement.

Advantages

The sleeved plastic construction offers additional protection and stability to the cable, helping to reduce wear and extending service life. The 300 mm length provides extra reach for routing fan cables in larger cases, and the neutral white finish integrates with light-coloured builds.

Suitable for

• Extending 4-pin PWM fan cables inside desktop PC cases
