An air stream distribution apparatus directs portions of an air stream, at substantially ambient temperatures, to serially arranged circuit board components of a circuit board assembly. The air stream distribution apparatus splits an incoming air stream into air stream portions and directs each air stream portion toward each serially arranged circuit board component. Such direction of the portion of the air stream, by the air stream distribution apparatus, minimizes overheating and failure of the circuit board components. Furthermore, the air stream distribution apparatus minimizes a decrease in the pressure of the air stream as the air stream travels from the air stream source. The air stream distribution apparatus, therefore, ensures that circuit board components located at relatively large distances from the air stream source receive air from the air stream to minimize overheating and potential failure.
