Final answer:
The cooling fan or air intake fan is the component in a computer that pulls and directs fresh air from outside the case to the cooler and processor, similarly to how an air conditioner or refrigerator works.
Step-by-step explanation:
Based on the question, the round air duct that helps to pull and direct fresh air from outside the case to the cooler and processor would be referred to as a cooling fan or air intake fan. These components are essential in maintaining the temperature of the device within safe operating ranges by moving cooler outside air over the warmer parts of the computer, such as the processor.
Akin to the way an air conditioner or a refrigerator works, the cooling fan in a computer effectively transfers heat away from the internal components and dispels it outside. This mechanism is crucial to prevent overheating of the processor and other vital components, which could result in hardware damage or failure.
