DC Fans, which are powered by a direct current, are important components that support the stable operation of all kinds of electronic devices. Among them, the G4020M12B-RS is a 120 × 120 × 38 mm high-speed fan with a full-metal grille and a double-ball bearing motor. Its advantages are low noise, high speed and long life.

The G4020M12B-RS is widely used in many industries, including telecommunication equipment and home appliances. It is especially suitable for cooling CPU, mainboard and graphics card and other heat sources. It can also be used in various types of automotive electronic equipment, such as headlight cooling, dashboard cooling, and motor cooling.

As for the working principle of the G4020M12B-RS fan, it is mainly based on the principle of air circulation. The fan is supplied with power and rotates rapidly. When the fan blades rotate, air is drawn by the fan blades and flung in the direction of the vanes, creating a low-pressure zone behind the fan blades. At the same time, the air around the fan is forced to move toward the low-pressure zone due to the positive pressure, thus forming a continuous loop of air flow.

In addition to the traditional low-pressure air-flow fan, the G4020M12B-RS fan can also be applied in the cooling operation of negative pressure. In this cooling method, the fan blades rotate to produce a vacuum, and the air near the fan blades is drawn in, forming a continuous air flow. This cooling method is usually used in PCs, allowing cool air to enter the enclosure while hot air is discharged from the fan.

To enhance the performance of the G4020M12B-RS fan, it adopts high-performance double-ball bearing motor. The double-ball bearing motor is a kind of bearing using two balls instead of rollers. The advantage of using two balls is that the bearing can withstand higher loads than the single-ball bearing, and the noise and vibration levels are also lower. This greatly improves the overall performance of the fan.

For a good cooling effect, the right fan speed can be selected depending on the requirements. It is worth noting that the higher the fan speed is, the higher the noise it will produce. Therefore, selecting a fan speed within the effective range is also an important consideration.

In short, the G4020M12B-RS fan is a low-noise, high-speed and long-life DC fan that is widely used in many applications, such as consumer electronics, automotive and medical equipment. It is mainly based on the principle of air circulation and adopts a double-ball bearing motor for better performance. It is a great choice for cooling various heat sources.
