An electronic device includes a bottom plate, a circuit board, a fan, and an airflow guide member. The circuit board is fixed to the bottom plate. The fan is arranged at the front of the circuit board. The airflow guide member is arranged between the fan and the circuit board. The airflow guide member includes an airflow guide wall for guiding most of airflow upwards to the top of the circuit board. A number of slots is defined in the airflow guide wall, for allowing only a minimum portion of the airflow to flow underneath the circuit board.
