Final answer:
Passive heat sinks, cooling fans, and shrouds are used to keep the video card cool.
Step-by-step explanation:
The video card in a computer generates a significant amount of heat while processing graphics and running demanding applications. To keep the video card cool, several methods are used, including passive heat sinks, cooling fans, and shrouds.
Passive heat sinks are usually made of metal and provide a large surface area for heat dissipation. They rely on conduction to transfer heat away from the video card. Cooling fans are designed to circulate air around the video card, facilitating heat transfer through convection.
Shrouds are used to direct the airflow generated by cooling fans, optimizing the cooling efficiency. Thermal glue, on the other hand, is not typically used to keep the video card cool but may be used in other applications that require a strong bond between components.
