Q. Is a computer fan really necessary?

Answer

Without enough ventilation, the heated air inside the casing might cause the system to overheat, which in turn can reduce its efficiency. The flow of air is essential in this regard. A computer's case fan is crucial to the machine's longevity. There is a risk of CPU overheating during operation, and the built-in fan may not be able to effectively cool the system. Since it is constantly running, the fan won't last as long as it should. As a matter of course, computer cases include built-in fans designed to keep the insides cool. When working on large projects, editing loads of images or videos, or playing a lot of games on the computer, a user may find that the included fans aren't up to the task.
