A heat dissipation system includes a computer case has a base plate and a back plate perpendicularly to the base plate, a heat sink, a first fan and an air duct. The heat sink is positioned in the computer case in contact with a first heat source. The first heat source and the back plate define a first air channel therebetween. The first fan is positioned in the computer case adjacent to a first side of the heat sink. The first fan is configured to generate airflow through the heat sink in such a manner that airflow flows from the computer case outside is sucked into the computer case via the first air inlet and the first air channel. The air duct is positioned in the computer case adjacent to a second side of the heat sink. The heat sink heats the airflow from the first fan. The warm airflow heated by the heat sink is then blown out of the computer case by the first fan via the air duct.
