Kolink PWM fan splitter cable 1-to-2, 35 cm braided black, model PGW-AC-KOL-111

Kolink PWM fan splitter cable 1-to-2, 35 cm braided black (model PGW-AC-KOL-111) is a compact cable that expands a single 4-pin PWM fan header into two 4-pin connectors. The 35 cm length with braided sleeving provides a tidy routing option inside PC cases while preserving PWM signal and power distribution so two case or CPU fans can be controlled from one motherboard or controller header.

Advantages

The splitter maintains PWM speed control for both fans, allowing the motherboard or fan controller to regulate RPM based on temperature. Braided sleeving improves durability and cable management, while the single-cable design reduces clutter and simplifies installation in tight spaces. The 4-pin connectors keep power and tachometer signals intact for reliable fan operation.

Suitable for

• Connecting two 4-pin PWM case fans to one motherboard header
• Expanding fan outputs on small form-factor or compact builds
• Linking two fans to a single fan controller channel
• Improving cable routing and reducing visible wiring in a PC case

Key specifications

• Cable type: 4-pin PWM fan splitter (1-to-2)
• Length: 35 cm
• Color and finish: black with braided sleeving
• Connector type: 4-pin female to two 4-pin male PWM connectors
• Signal support: PWM speed control and tachometer signal pass-through

How to use

Connect the single end of the splitter to an available 4-pin PWM fan header on the motherboard or to a compatible fan controller. Attach up to two 4-pin fans to the splitter's output connectors, ensuring correct pin alignment. After connection, verify in BIOS or fan-control software that both fans are detected and responding to PWM duty-cycle adjustments. Avoid connecting high-current devices other than standard case or CPU fans to prevent overloading the header.

Recommendations

Use this splitter for two standard PWM fans whose combined current draw does not exceed the motherboard header or controller channel specification. For high-power fans or multiple-fan setups, consider using a powered fan hub or a separate PWM hub with independent power supply to avoid exceeding header current limits.
