DC Fans

A DC fan or direct current fan is a type of fan motor used to move air or gas at relatively low pressure levels. DC fans use the same principle as all other types of fans, namely to create a low pressure area behind the fan blades thus creating a flow of air or gas across the fan and out to the atmosphere. The primary difference between a DC fan and an alternating current (AC) fan is that a DC fan draws power directly from a DC power source such as a battery, whereas an AC fan utilizes a transformer to drive the fan\'s AC current.

9GA0912G402 Application Field and Working Principle

The 9GA0912G402 is a 120mm DC fan that can provide reliable, efficient cooling for different computing platforms and electronics devices. The 9GA0912G402 fan features an on/off switch which allows the user to manually control its operation and runs at a maximum rotational speed of 2000 RPM. The 9GA0912G402 fan features a thermal protection circuit that ensures that it will not over heat and shut down due to high temperatures.

The 9GA0912G402 is well-suited for applications requiring low noise, low-power consumption, and reliable cooling of electronics and computers. It operates using an external brushless DC motor, and a 2-pin, closed-loop speed control design. The fan can operate at multiple speeds and handle airflows of up to 45 CFM. The 9GA0912G402 features an innovative airflow design that enables it to pull air from above and circulate it through the interior of the case at a consistently high speed.

The 9GA0912G402 fan also features a unique bearing design which prolongs its life cycle because the bearing absorbs less energy from the airflow. This makes the fan quieter and can significantly reduce noise levels in the surrounding environment. The fan\'s maximum sound level is only 32dB, making it one of the quietest 120mm fans on the market. Additionally, it features an optional speed control switch for users who want to adjust the fan speed and noise levels with greater precision.

The 9GA0912G402 DC fan is an ideal choice for users who are looking for a reliable and efficient cooling solution for their computer chassis or computing applications. Its low noise levels and long life span combined with its efficient cooling and airflow make the 9GA0912G402 an attractive choice for anyone seeking to maximize their system\'s cooling performance without sacrificing noise levels. It is also designed to be easy to install, making it an ideal choice for DIY enthusiasts and overclockers.
