3-pinový predlžovací kábel Alphacool 18687, 60 cm, 3-pinový predlžovací kábel ventilátora/napájania

Alphacool 18687 is a 60 cm 3‑pin extension cable that increases reach for 3‑pin fans and compatible devices. The cable provides a direct wired extension for standard 3‑pin fan headers without signal conversion, enabling flexible cable routing inside PC cases and easier placement of cooling components. Its straightforward connector design ensures compatibility with common motherboard and fan connectors designed for 3‑pin power and tachometer signals.

Advantages

The extension cable offers a simple solution to extend fan and device connections by 60 cm while preserving original signal integrity. It supports standard 3‑pin connectors so no adapters or additional wiring are required. The cable's length and flexible construction simplify cable management, reduce strain on original connectors, and facilitate cleaner internal layouts in computer cases.

Suitable for

• Extending 3‑pin PC fan connections to reach distant motherboard headers
• Repositioning fans for improved airflow or mounting flexibility
• Routing fan power and tachometer cables through cable channels or behind trays
• Connecting simple 3‑pin powered devices in cramped or custom builds

Key specifications

• Connector type: 3‑pin female to 3‑pin male
• Cable length: 60 cm
• Supported signals: power (12 V) and tachometer (RPM) without PWM control
• Compatibility: standard 3‑pin fan headers on motherboards and devices
• Construction: flexible insulated conductors with molded connector housings

How to use

Align the male and female 3‑pin connectors and insert them firmly until they seat. Ensure the connector orientation matches the header keying on the motherboard or fan connector to avoid miswiring. Route the cable to minimize sharp bends and avoid contact with moving fan blades. For best results, secure excess cable with ties or routing channels inside the case to maintain airflow and reduce vibration transfer.

Recommendations

Use this extension for passive extension of power and RPM signal lines only; it does not provide PWM control lines for 4‑pin fans. Avoid excessive bending or tight clamping near connector ends, and disconnect power before installing or removing the cable.
