3-pin vs. 4-pin cooling fan: Analysis of advantages and disadvantages of PWM speed regulation and voltage speed regulation
Mar 24 , 2025
Cooling fans play a crucial role in electronic equipment, servers, industrial equipment and other fields. For different use needs, there are two main types of 3-Pin (3-pin) and 4-Pin (4-pin) fans on the market, and their main difference is the speed regulation mode - 3-pin fan speed regulation by voltage, while 4-pin fan uses PWM (pulse width modulation) speed regulation. So, what are the advantag...

Why Do Blowers Usually Have Higher Static Pressure Than Axial Fans?
Sep 12 , 2025
Fans and blowers are often compared in various cooling and ventilation systems. While both can move air, the difference in static pressure performance makes them suitable for very different applications. A cooling fan is known for providing large volumes of airflow with relatively low energy consumption. Its blades directly push air forward, making it highly effective in generating high air flow i...
