Converging cooling duct for a computer cooling system

A method comprising:

• drawing and accelerating air from outside a computer system chassis by an air moving unit to a high velocity airflow through an air moving unit base;
• and
• converging and changing, via a duct having an angled section and a substantially rectangle outlet, the high velocity airflow from a circular shape to a noncircular shape through a duct;
• and
• directing the converged and changed high velocity airflow to cool a device within a computer system chassis.

A computer system comprising:

• a chassis;
• a processor core logic (PCL) components;
• and
• a cooling duct unit to fit within the chassis thermally connected to the PCL components to cool the PCL components, wherein said cooling duct unit comprises:
• an air moving unit base;
• an air moving unit, coupled to the air moving unit base, to draw and accelerate air from outside a computer system chassis to a high velocity airflow;
• and
• a duct, coupled to the air moving unit base, the duct having an angled section to converge and change the high velocity airflow from a circular shape to a noncircular shape, the duct further including a substantially rectangle outlet.
