PWM fan splitter cable Kolink PGW-AC-KOL-160, 35 cm braided white, 1-to-2 PWM connector

Kolink PGW-AC-KOL-160 is a 35 cm braided white PWM fan splitter cable that enables a single 4-pin PWM motherboard header to power and control two PWM fans. The splitter maintains PWM signal integrity so fan speed and automatic control remain functional while providing a neat sleeved finish to improve internal cable management and visual consistency in PC builds.

Advantages

The cable supports full 4-pin PWM control for both connected fans while using only one motherboard header, preserving synchronized speed adjustments and temperature-based fan curves. The braided sleeve reduces abrasion and tangling, and the compact 35 cm length minimizes excess cable inside the chassis. The white sleeving is designed for aesthetic compatibility with light-themed builds and helps keep wiring organized without adapters or soldering.

Suitable for

• Adding a secondary PWM fan where only one motherboard header is available
• Improving airflow in compact or mid-tower PC cases
• Custom builds that require a clean, sleeved cable appearance
• Temporary fan upgrades or testing multiple fans with one header

Key specifications

• Cable type: 1-to-2 PWM fan splitter
• Connector format: 4-pin PWM female to two 4-pin PWM male connectors
• Length: 35 cm (braided sleeving length)
• Colour: white braided sleeve
• Signal support: PWM speed control preserved for both outputs
• Construction: sleeved wiring with molded connector housings

How to use

Connect the single 4-pin PWM end to an available motherboard fan header designed for PWM control. Attach up to two 4-pin PWM fans to the splitter outputs, ensuring connectors are fully seated and oriented correctly. After connection, verify in BIOS or fan control software that both fans are detected and respond to PWM adjustments. Route the braided cable along the case edges or behind the motherboard tray to minimize airflow obstruction and secure it with cable ties if necessary.

Recommendations

Do not exceed the current rating of the motherboard header—check your motherboard manual for the maximum supported fan current when running two fans from one header. Use fans with similar power draw and speed profiles when possible to maintain predictable PWM behaviour. Avoid stretching or sharply bending the cable near connectors to prevent damage to the wiring and maintain signal reliability.
