Overheating is a key factor affecting the lifespan of laptop hardware. High temperatures can accelerate the aging of electronic components and shorten the service life of components such as the motherboard and battery. The cooling pad effectively controls the temperature and slows down the aging rate of components. For example, it can slow down the rate of capacity degradation of the laptop battery after multiple charge - discharge cycles, extend the overall service life of the battery, and reduce the maintenance or replacement costs caused by premature hardware damage. Using a cooling pad can keep the laptop cool during use. In hot summer, without a cooling pad, the bottom of the laptop may be too hot to touch, but after using it, hand discomfort can be avoided, allowing users to operate the laptop more comfortably. At the same time, the noise generated by the cooling pad during operation is usually low and will not interfere with the user's concentration during office work, study, or entertainment, creating a quiet using environment.
