Cabo 4-Pin-PWM e ventoinha 3-Pin Akasa AK-CBFA01-30

The Akasa Cable 4-pin PWM and 3-pin fans AK-CBFA01-30 is a 30 cm internal fan extension cable designed to connect and extend 4-pin PWM or 3-pin fan headers inside a PC chassis. Its compact length and black finish support tidy cable routing and compatibility with a variety of fan types and motherboard headers, enabling flexible placement of cooling fans and improved airflow management in desktop systems.

Advantages

This cable supports both 4-pin PWM control and 3-pin fan connections, allowing speed regulation when connected to PWM-capable headers while remaining compatible with simpler voltage-controlled fan ports. The 0.3 m length provides a balance between reach and neatness, reducing excess cable clutter. The black sleeving and standard connector housings ensure unobtrusive integration into most builds and straightforward installation without additional adapters.

Suitable for

• Extending internal fan connections to reach distant headers inside desktop PC cases
• Connecting PWM-controlled fans to motherboard headers for automatic speed control
• Replacing short or damaged fan cables without changing the fan unit
• Improving cable management and airflow routing in compact or mid-tower builds

Key specifications

• Cable length: 0.3 m
• Connector type: 4-pin PWM compatible (also supports 3-pin fans)
• Colour: Black
• Usage: Internal PC fan extension

How to use

Power down the PC and disconnect it from the mains before installing the cable. Detach the fan connector from the motherboard or fan hub, insert one end of the extension cable into the fan’s connector, and connect the other end to the motherboard header or fan controller. Ensure the keyed housing aligns correctly to avoid pin misalignment. After connecting, secure routing to avoid interference with moving components such as fan blades and verify fan operation before closing the case.

Recommendations

Use this cable when you need modest extension without adding length that could impede airflow; for PWM-controlled fans, connect to a PWM-capable header to retain automatic speed control. Avoid bending the cable sharply near the connectors and route it away from heat sources and moving parts to maintain reliable operation.
