This 6-inch adapter cable connects a 3-pin computer fan to a 4-pin Molex power connector, allowing for versatile fan installation in systems with limited motherboard fan headers. The cable features a standard 3-pin female connector on one end, compatible with most computer case fans, and a 4-pin Molex male connector on the other, which plugs directly into the power supply. This adapter enables users to power additional fans, improving system airflow and cooling performance. The compact 6-inch length provides sufficient reach while minimizing cable clutter inside the case. Ideal for custom PC builds, server setups, or upgrading cooling in older systems.
