Akasa fan splitter bundle AK-CBFA04-KT04 — 4-pack PWM fan splitter cable

Akasa AK-CBFA04-KT04 — 4-pack PWM fan splitter cable bundle provides four identical 4-pin PWM fan splitters that allow multiple PWM fans to be connected to a single motherboard or fan controller header. Each splitter preserves the PWM signal and tachometer feedback so that connected fans can be speed-controlled and monitored from one header, helping to simplify cable routing and expand cooling capacity in desktop PC systems.

Advantages

The bundle offers a compact and consistent solution for connecting up to four PWM fans per header without modifying fans or headers. Preserving the 4-pin PWM and tachometer lines enables centralized speed control and monitoring. The splitters are simple to install, reduce cable clutter in the case, and are suitable for standard 4-pin fan connectors used in most modern motherboards and fan controllers.

Suitable for

• Expanding system cooling by connecting multiple case fans to one motherboard header
• Building compact or budget PC systems that need synchronized PWM control
• Replacing or extending short fan cables when routing limits exist
• Connecting multiple fans to a fan controller with limited headers

Key specifications

• Connector type: 4-pin PWM female to multiple 4-pin PWM male split
• Pack quantity: four identical splitter cables included
• Signal support: PWM speed control and tachometer (RPM) feedback preserved
• Cable length: typical splitter lead lengths suitable for standard PC case routing (individual lengths may vary)
• Compatibility: standard 4-pin PWM fans and motherboard headers

How to use

Connect the single 4-pin female end of a splitter to a motherboard fan header or compatible fan controller header. Attach up to the provided number of 4-pin male fan connectors to the splitter outputs, ensuring correct orientation of the connector latch. Once connected, the motherboard or controller will detect and control fan speeds via the PWM signal while monitoring tachometer feedback. Use separate splitters from the bundle to distribute fans across multiple headers if required.

Recommendations

Ensure the combined current draw of connected fans does not exceed the power and current limits of the motherboard header or fan controller. If multiple high-current fans are used, consider powering them from a dedicated power source or using a powered fan hub. Route cables to avoid obstructing airflow and secure connectors to prevent accidental disconnection.
