Cable extension Alphacool 18673 Plastic Black 150mm

The Alphacool 18673 cable extension is a 150mm accessory made of durable black plastic for 4-pin PWM fans. It extends the reach of fan cables to help organize wiring inside PC cases while providing added protection and stability thanks to its sleeving.

Advantages

The sleeving improves cable protection and mechanical stability, reducing wear over time. The 150mm length offers extra reach for flexible fan placement and cleaner cable routing without introducing additional electronic components.

Suitable for (tasks / use cases)

• Extending 4-pin PWM fan cables in desktop PC builds
• Improving cable routing for better airflow and tidier interiors
• Connecting fans to fan hubs or motherboard headers located away from the fan
