Fan PWM Splitter Cable Kolink 1-to-3, 4-pin PWM, 0.35 m

Kolink 1-to-3 Fan PWM Splitter Cable is a 0.35 m 4-pin cable that converts a single motherboard or controller PWM header into three 4-pin PWM outputs. It enables connection of up to three PWM fans to one PWM header while preserving PWM speed control, so fan speeds respond to system temperature or BIOS fan curves. The cable is supplied as a single assembled piece and is intended for PC cooling configurations that require multiple fans on one PWM channel without additional wiring complexity.

Advantages

The splitter keeps PWM control for all connected fans, allowing unified speed regulation from one motherboard header. Its compact 0.35 m length reduces cable clutter inside compact or mid-tower cases. The 4-pin connectors maintain standard pinout for power, ground, tachometer and PWM signal, ensuring compatibility with typical PWM fans and controller headers. The single-piece design simplifies installation compared with custom-soldered solutions and reduces the need for extra adapters.

Suitable for

• Expanding a single motherboard PWM header to power multiple case fans
• Setting up intake or exhaust fan groups that should follow one PWM curve
• Small builds where fan controller ports are limited
• Temporary or permanent multi-fan arrangements on one fan channel

Key specifications

• Cable length: 0.35 m
• Connector type: 4-pin PWM female to three 4-pin PWM male outputs
• Number of outputs: 3
• Signal support: PWM speed control with tachometer (RPM) feedback
• Compatibility: Standard 4-pin PWM fans and 4-pin motherboard/controller PWM headers

How to use

Connect the single 4-pin end of the Kolink PWM splitter to an available 4-pin PWM header on the motherboard or fan controller, ensuring correct alignment of the connector key. Attach up to three PWM fans to the three 4-pin outputs. After connection, configure fan control in the system BIOS or fan control software so the connected fans follow the desired PWM curve. Verify that the combined current draw of connected fans does not exceed the header or controller specifications to avoid overloading.

Recommendations

Use this splitter for grouping fans that should operate under the same PWM control. For high-power fans or large numbers of fans, check motherboard header current limits and consider using a powered fan hub or separate controller to prevent overcurrent on the PWM header.
