Which of the following is used in a server to ensure proper cooling and airflow when components are removed?

A heatsink dissipates heat from a specific processor or chip through conduction and convection, but it does not guide or maintain chassis-wide airflow when slots are empty.

A voltage regulator manages and stabilizes power delivery to components and has no role in cooling or directing airflow.

Server baffles (also called air dams or filler panels) are designed to channel airflow through specific paths inside the chassis. When components such as hard drives or expansion cards are removed, open slots can disrupt the intended airflow pattern, causing hot spots. Baffles block these gaps and ensure cool air moves efficiently across remaining components.

Liquid cooling transfers heat away from specific components via a coolant loop, but it does not address gaps in the chassis that disrupt airflow when hardware is removed.
