What is one of the main disadvantages of using active cooling systems in computers?

One of the main disadvantages of using active cooling systems in computers is that they produce additional noise. Active cooling systems, which often consist of fans or liquid cooling pumps, generate sound as they operate to move air or coolant through the system to dissipate heat. This noise can be particularly noticeable in a quiet environment, making it a consideration for users who prioritize a silent operation, such as those working in audio production or in home theater setups.

While effective at cooling and offering better performance in high-demand scenarios, this noise factor is a primary reason some users might prefer passive cooling solutions, which rely on heat sinks and do not include moving parts, thereby eliminating sound generation.
