A laptop cooling fan cools the internal components of a laptop and prevents them from overheating. It removes warm air from the engine while blowing cool air over the cylinder head. It is also used as a buffer by mobile users to insulate the warm bottom of the laptop from their laps. It generally has high efficiency and low noise. It usually connects to a laptop through the USB port.
Types of Laptop Cooling Fans
Kinds of Laptop Cooling Fans include the following:
Three-phase laptop cooling fan
A three-phase cooling fan uses a three-phase DC motor that helps reduce power in cooling the device. It has low noise operation.
Single-phase laptop cooling fan
A single-phase cooling fan is an upgrade of the three-phase laptop cooling fan. It uses a single, brushless coil as opposed to the several brush motors used by the three-phase model.
Choosing Laptop Cooling Fans (Buying tips)
Noise reduction: Choose a laptop cooling fan that does not generate noise when in use. Look for one with a buffer to reduce the buzzing of the fan motor.
