For industrial applications, DC fans are often used for cooling or ventilation as they require less maintenance and cost when compared to an AC motor installed fan. The 3414NGM DC fan is a type of fan specifically designed to have a minimal noise output, while still providing a high airflow and static pressure output.

Design

The 3414NGM is a brushless DC fan installed with motors that are held within a die-cast aluminum frame. This construction, along with the built-in noise reduction fan blades, helps reduce the noise output previously mentioned. Additional design features, such as the seven blades that maximize airflow, and a single ball bearing, low-noise motor design, allows for longevity, and an airflow/static pressure output performance rate that exceeds other DC fans.

Specifications

The 3414NGM comes in sizes of 120mm and 140mm, and is available in voltage ratings of 12VDC to 48VDC. It has a maximum operating temperature of 70°C and is UL94V-0 and RoHS compliant. The fan also has a maximum airflow of 98.18CFM for its 120mm version, with a pressure of 3.43mm H2O.

Application Field

Due to its noise reduction capabilities and its powerful airflow/pressure outputs, the 3414NGM DC fan is often used in many applications such as for cooling and ventilation in switches, power supplies, mini PCs, and gaming systems. It is also used as a supplementary cooling fan for CPUs, high-end graphics cards, and power devices as well.

Working Principle

The 3414NGM is a brushless DC fan, meaning the motor is governed using an electronic control circuit with several Hall effect devices, mounted on the rotor. These devices measure the position of the rotor, and the circuit then determines the current that needs to be sent to the windings. The electric current then generates a magnetic field and this causes the rotor to rotate. As the speed of the motor changes, the power is regulated by altering the current through the windings, resulting in a low noise output.

Conclusion

The 3414NGM DC fan is an advanced and reliable fan that offers an impressive output despite its low noise. With its enhanced design features, this fan can be used in many applications, ranging from cooling and ventilation in computers and electronic systems, to supplementary cooling methods. In addition, its working principle ensures that the fan does not produce any unwanted noise.
