Abstract: An exemplary fan apparatus includes a cooling fan and a fan gate attached to the cooling fan. The cooling fan defines an air inlet and an air outlet at two opposite sides thereof. The fan gate includes a mounting frame fixed on the cooling fan and surrounding the air outlet, and an airflow valve extending from the mounting frame. The airflow valve is bendable relative to the mounting frame. When the cooling fan works, an airflow produced by the cooling fan flows to the fan gate and pushes the airflow valve to bend with respect to the cooling fan to cause the air outlet to be exposed. When the cooling fan does not work, the airflow valve covers the air outlet.
