Cable adapter Kolink 4‑Pin fan to 3‑Pin 5V ARGB, 0.4 m

The Kolink Cable adapter 4‑Pin fan to 3‑Pin 5V ARGB, 0.4 m is a passive wiring accessory designed to adapt a standard 4‑pin fan connector to a 3‑pin 5V ARGB header. The short 0.4 m length provides a neat, direct link between a fan's connector and a 5V ARGB input on a motherboard, controller, or hub, enabling addressable RGB lighting to be connected where wiring formats differ. This adapter is intended for situations where the mechanical fit of connectors and signal/power compatibility are aligned with 3‑pin 5V ARGB wiring.

Advantages

The cable offers a compact, low-profile solution for integrating fans with 5V addressable RGB into systems that use 3‑pin ARGB headers without requiring soldering or complex rewiring. Its passive design means no additional power electronics or signal conversion is included, preserving native ARGB signaling when connectors are compatible. The short length reduces cable clutter inside the chassis and helps maintain tidy airflow paths and component placement.

Suitable for

• Connecting a 4‑pin fan cable to a 3‑pin 5V ARGB header on a motherboard
• Adapting fan lighting to third‑party ARGB controllers and hubs that use 3‑pin 5V wiring
• PC builds and upgrades where a simple connector conversion is needed without modifying the fan or header

Key specifications

• Connector conversion: 4‑pin fan connector to 3‑pin 5V ARGB connector
• Cable length: 0.4 m
• Design: passive adapter (no active electronics)
• Intended signal type: 5V addressable RGB (ARGB)
• Use environment: internal PC case wiring

How to use

Ensure both the fan and the target header or controller support 5V addressable RGB signaling and that pinouts match before connecting. Plug the 4‑pin end into the fan connector and align the 3‑pin end with the 5V ARGB header on the motherboard or controller, taking care to match the 5V, data, and ground orientation. Route the cable along the case edges to minimize interference with fans and other components. Because the adapter is passive, no configuration is required beyond verifying compatibility in the system firmware or lighting software.

Recommendations

Verify connector pinouts and voltage compatibility before use to avoid potential damage to LEDs or headers. Use the 0.4 m length for short internal routing; for longer distances, consider alternative cabling or repeaters designed for ARGB signals. If lighting does not respond after connection, check software settings, header enablement in BIOS/UEFI, and physical seating of the connectors.
