Which of the following components channels air flow through a server chassis?

A fan generates the air movement but does not channel or direct the flow through specific pathways; it merely provides the airflow.

A heat sink absorbs and dissipates heat from a component but does not channel the overall air movement within the chassis.

A shroud is a component, often made of plastic or metal, that surrounds fans or internal components to channel and direct airflow precisely. In a server chassis, shrouds ensure that cool air passes effectively over heat-producing components like CPUs and RAM modules, optimizing cooling efficiency.

A radiator is typically used in liquid cooling systems to dissipate heat from a liquid coolant, not to directly channel air within a server chassis.
