• Circulates air for cooling or ventilation so components run within intended temperature ranges
• Replaces worn or damaged fan blades that cause reduced airflow
• Stops or reduces unusual grinding, rattling, or vibration linked to a failing fan
• Helps prevent heat build-up that can lead to thermal shutdowns or reduced efficiency

• One replacement fan

• Disconnect power (unplug or shut off breaker) before starting any repair
• Access may require removing panels or moving other components; keep fasteners organized
• Inspect the fan housing and motor mounts during install; replace damaged clips or screws
