What is power supply cooling fan?

FB0712VHD-BT07 Delta

A power supply cooling fan is a small, dedicated fan (typically DC-powered) built into—or mounted onto—a power supply unit (PSU) to remove heat generated during its operation. Since power supplies convert and regulate electrical energy (e.g., AC→DC conversion, voltage regulation, and filtering), they naturally produce heat. Without adequate airflow, internal temperatures can rise, leading to reduced efficiency, increased electrical noise, and ultimately shortened component life or failure.
