Adaptador de alimentação de ventoinha Kolink 3-Pin para 2×4-Pin Molex, 245 mm, preto

Adapter cable by Kolink that converts a single 3‑pin PC fan power connector to two 4‑pin Molex connectors. The cable is 245 mm long and finished in black, designed to let users power fans or simple peripherals from standard Molex power lines. It is suitable for retrofit work, repairs and custom PC builds where a single fan header needs to be adapted to Molex-based power sources.

Advantages

This adapter provides a straightforward electrical conversion from a 3‑pin fan connector to two 4‑pin Molex plugs without additional circuitry, offering a compact and practical solution for powering or testing fans and basic devices. The fixed 245 mm length balances reach and cable management, while the black finish helps the cable blend into typical PC interiors. The simple plug‑and‑play design requires no software or extra configuration.

Suitable for

• Powering 3‑pin PC fans from Molex power lines
• Temporary fan testing and diagnostics
• Retrofit or repair of older systems lacking free fan headers
• Custom PC builds where Molex power is used for peripherals

Key specifications

• Connector conversion: 1 × 3‑pin fan female to 2 × 4‑pin Molex male
• Cable length: 245 mm
• Colour: black
• Purpose: power/adaptation of fans and simple peripherals
• Installation type: internal PC cable

How to use

Insert the 3‑pin fan plug into the fan header on the cable and connect the two 4‑pin Molex plugs to available Molex power outputs from the power supply. Ensure correct orientation of connectors before applying power. Use one or both Molex plugs as required by the connected device; secure loose cables to avoid contact with moving components. This adapter does not convert signal protocols or supply PWM control; it only provides direct power lines.

Recommendations

Check that the connected fan or peripheral power requirements are compatible with the Molex supply voltage and current. Avoid routing the cable across sharp edges or close to high‑temperature components. For PWM speed control or advanced fan monitoring, use native motherboard headers or dedicated controllers rather than this passive adapter.
