The difference between cooling fans and radiators (sheets)


The cooling fans, also known as air cooling, generate wind through the high-speed rotation of the fans, which in turn take away the heat generated by the device. They have the advantages of relatively low price and simple installation, but they are highly dependent on the environment. For example, in extremely cold regions and overclocking, their cooling effect may be affected. At present, the cooling fans used in the industry are divided into DC cooling fans, AC cooling fans, EC energy-saving fans, DC blowers (turbo fans), cooling fans with PWM speed-adjustable function, cooling fans with temperature control function, and FG power supply Cooling fan, cooling fans with soft-start function, cooling fans with self-starting function, etc.
A radiator is a piece of metal, also known as a heat sink. The function of the radiators is to absorb the heat of the device, and then dissipate it into or out of the chassis to ensure the normal temperature of the computer components. The heat dissipation function of the heat sink is mainly determined by the thermal conductivity of the material and the areas of the heat sink in contact with the air. Most heat sinks absorb heat by contacting the surface of the heat-generating components, and then transfer the heat to a distance through various methods, such as transferring the hot air from the chassis to the outside of the chassis to complete the heat dissipation of the computers. There are many types of radiators, CPUs, graphics cards, motherboard chipsets, hard drives, chassis, power supplies, and even optical drives and memory will require radiators. Different radiators cannot be mixed, and the most common one is the CPU radiators. Heat sinks can be divided into active heat dissipation and passive heat dissipation according to the way in which heat is removed from the heat sink.
In actual operation, the cooling fans and the heat sink often need to fight side by side. The heat sink is responsible for transmitting the heat, dispersing the concentrated heat to itself, and the cooling fans rotate and use the airflow to take away the heat.
