1Pcs IDE Molex D Plug to 3 Pin Fan Power Cable, 4Pin Molex to 3Pin Connector Adapter Cable for PC Computer Cooling Fan

This IDE Molex to 3Pin fan power adapter cable is a practical hardware conversion accessory specially designed for desktop computer DIY enthusiasts. It converts the common 4Pin IDE Molex D power port from your PC power supply into a 3Pin fan interface, perfectly solving the shortage of fan headers on motherboards.

Many motherboards only come with limited fan connectors. When you plan to install extra chassis cooling fans, radiator fans or auxiliary ventilation fans, this adapter cable allows you to draw power directly from the power supply unit via Molex power lines instead of occupying motherboard fan ports.

Manufactured with high-purity conductive copper wire and multi-layer insulation materials, the cable features excellent electrical conductivity and anti-interference performance. The reinforced connectors offer tight insertion force to avoid poor contact, power cut-off and fan stall caused by loose plugs during long-term operation.

Adopting plug-and-play design, no complicated wiring or software setup is required. Just plug the 4Pin Molex terminal into the PSU Molex power output, then connect the 3Pin port to your cooling fan to finish installation.

This adapter fits all standard 3Pin non-PWM computer case fans. Important reminder: This cable only transmits power for fan operation. It cannot transmit fan speed signal and does not support PWM speed regulation, so the fan will run at a constant speed after power on.

Great for PC assembly, hardware upgrade, chassis airflow modification, server case heat dissipation and other computer renovation projects. Compact and flexible wire layout helps you arrange internal chassis cables neatly and optimize airflow inside the computer case.
