The 40x40x56mm DC Axial Fan is a compact yet powerful cooling solution designed for applications where space is at a premium. With its small footprint (40mm x 40mm) and height of 56mm, this fan is ideal for use in compact electronic devices, embedded systems, small power supplies, and other equipment where traditional larger fans cannot fit. Despite its compact size, it delivers impressive airflow and static pressure, making it a reliable choice for cooling heat-generating components in confined spaces. The fan operates on direct current, with common voltage ratings including 5V, 12V, and 24V, ensuring compatibility with a wide range of low-power electronic systems.

The design of the 40x40x56mm DC Axial Fan is optimized for both performance and space efficiency. The fan blades are carefully engineered to maximize airflow within the limited dimensions, with a compact hub and short blade length that do not compromise on air-moving capacity. The blade material is typically high-quality plastic such as PBT or ABS, which offers good heat resistance and mechanical strength, ensuring that the fan can withstand the high temperatures often found in compact electronic enclosures. The fan’s motor is also compact, with a slim design that fits within the 56mm height, while still featuring high-quality components such as copper windings and a precision-balanced rotor to ensure smooth operation and long lifespan.

Technical specifications of the 40x40x56mm DC Axial Fan vary slightly depending on the voltage and model, but generally include airflow rates between 15 and 40 CFM and static pressure ranging from 50 to 150 Pa. These parameters make it suitable for cooling small heat sinks, voltage regulators, and other components in devices such as routers, switches, industrial controllers, and small form factor PCs. The fan’s operating temperature range is typically between -20°C and 70°C, allowing it to function reliably in both indoor and outdoor environments, as well as in harsh industrial conditions. Noise levels are very low, usually between 25 and 40 dB(A), making it suitable for use in quiet environments such as offices, laboratories, and residential settings.

Installation of the 40x40x56mm DC Axial Fan is simple and straightforward, thanks to its standard 40mm mounting hole pattern, which is widely used in compact electronic equipment. The fan can be mounted using small screws or clips, and it is compatible with standard fan connectors such as 2-pin, 3-pin, or 4-pin PWM connectors, depending on the model. PWM-enabled versions allow for variable speed control, which is particularly useful in applications where energy efficiency and noise reduction are important. The fan also features a built-in thermal protector in some models, which shuts off the fan if it overheats, preventing damage to the fan and the equipment it cools.

The versatility of the 40x40x56mm DC Axial Fan is one of its key strengths. It is commonly used in networking equipment, such as routers and switches, where it cools the internal CPU and power supply components. It is also a popular choice for embedded systems, such as single-board computers (SBCs) like Raspberry Pi and Arduino, which can overheat during intensive tasks. In industrial applications, it is used in small industrial controllers, sensors, and power inverters, where it ensures reliable operation in confined spaces. Additionally, it is used in consumer electronics such as DVRs, set-top boxes, and gaming consoles, where it helps maintain optimal operating temperatures without adding excessive noise. With its compact size, reliable performance, and wide compatibility, the 40x40x56mm DC Axial Fan is an essential cooling component for a wide range of small electronic devices.
