Without a functioning fan, your laptop would quickly overheat, leading to reduced performance, damage to internal components, and potentially even complete system failure.
How Laptop Fans Work
Laptop fans work by using a blade-and-bearings design to create airflow. The fan blades spin rapidly, creating a current of air that draws heat away from the laptop’s internal components and exhausts it out of the chassis. The fan is typically controlled by the laptop’s BIOS (Basic Input/Output System) or operating system, which monitors the laptop’s temperature and adjusts the fan speed accordingly.
Fan Speed and Noise
The speed at which a laptop fan spins is directly related to the amount of noise it produces. When a fan is running at a higher speed, it tends to produce more noise. This is because the fan blades are spinning faster, creating more turbulence and vibration, which in turn generates more noise. Conversely, when a fan is running at a lower speed, it produces less noise. However, if the fan is not running fast enough to effectively cool the laptop, it can lead to overheating and potentially cause damage to internal components.
