Fan interconnection board Akasa AK-CBFA04-15

The Akasa PWM Fan Hub AK-CBFA04-15 is a compact 4-pin fan interconnection board that lets you connect multiple PWM fans to a single motherboard CPU-fan header. Designed for PC builders and system upgraders, this black splitter simplifies cable routing while enabling synchronized fan speed control from the motherboard for better airflow and temperature management.

Advantages

The Akasa hub supports multiple 4-pin PWM fans from one header, reducing cable clutter and making internal cable management easier. It enables synchronized fan speed control based on motherboard temperature readings, improving cooling efficiency during load. The unit is lightweight and compact, fitting into tight spaces inside a case, and includes an adhesive backing for tool-free mounting. Constructed with durable materials, it is intended for reliable long-term operation.

Suitable for

• Custom PC builds where multiple case or CPU fans need to be controlled from one PWM header
• Upgrading cooling in small or compact cases with limited fan headers
• Improving airflow management in gaming rigs, workstations, or home PCs

Key specifications

• Model: AK-CBFA04-15
• Type: 4-pin PWM fan hub / splitter
• Max fan connectors: 4 (4-pin PWM)
• Connection: connects to motherboard CPU fan header
• Colour: Black
• Diameter / cable length: 15 cm
• Weight: 0.0073 kg

How to use

Connect up to four compatible 4-pin PWM fans to the hub’s fan sockets, then plug the hub’s lead into the motherboard CPU fan header. The motherboard will read temperatures and adjust all connected PWM fans accordingly, providing synchronized speed control. Secure the hub inside the case using the included adhesive backing to prevent movement that could stress cables or connectors.

Recommendations

Ensure your fans support PWM control and mount the hub firmly to avoid movement; verify that the combined current draw of connected fans does not exceed the motherboard header specifications.
