With the advancement of technology, the technology and performance of cooling fans are also constantly developing and improving. At present, the specifications and dimensions of heat dissipation fans range from a few millimeters to several hundred millimeters, and there are various voltage options, such as 5V, 12V, 24V, etc. In addition, there are also various shapes of heat dissipation fans, such as square, circular, olive shaped, etc.
In modern home life, technological progress has not only changed our way of life, but also improved our quality of life. The emergence of smart toilets is undoubtedly a major innovation in the bathroom field. They are equipped with heating seats, warm air drying, automatic flushing and other functions, making users feel extremely comfortable during use while effectively reducing the risk of infection caused by unclean bathroom facilities.
In the fast-paced modern life, the emergence of dishwashers has brought about earth shattering changes in our home life. Washing dishes is a tedious and time-consuming task that requires us to personally clean every dish, dry it, and store it in the sun.
The emergence of drones has provided us with new ways and perspectives to understand things. In the past decade, their applications have become increasingly popular. The express delivery industry, film and television shooting, monitoring and inspection, transportation, agriculture, forestry, police security, surveying and mapping, and other fields have shown a significant increase in demand for drones.

The DC axial fan 4010 is a high-efficiency solution specifically designed for router cooling, its core advantage lying in the perfect balance between compact size and quiet operation. This ultra-thin 40×40×10mm fan uses brushless motor technology, supports 5V/12V dual voltage adaptation, and delivers an airflow of up to 5CFM while keeping noise levels below 25dB, equivalent to the ambient sound of a library. The bearings feature a nano-ceramic coating, ensuring a lifespan of over 30,000 hours under the common 50℃ operating conditions of routers.
Three key points to note during installation: First, ensure the distance between the fan and heat source (such as a CPU heatsink) does not exceed 3mm to improve heat conduction efficiency; second, prioritize an outward-exhausting airflow design to avoid hot air recirculation; finally, it is recommended to implement intelligent temperature control via a PWM interface, automatically increasing the fan speed when the chip temperature exceeds 60℃. Actual testing shows that adding the 4010 fan can lower the router's surface temperature by 12-15℃, effectively preventing WiFi signal fluctuations caused by high temperatures.
For maintenance, clean the fan blades with compressed air every 6 months to remove dust. When not in use for extended periods, disconnect the power supply to prevent the bearing grease from hardening. Compared to the common 4020 fan, the 4010 saves 50% of vertical space, making it particularly suitable for modern ultra-thin router designs. Some high-end models also support IP5X dustproof certification, making them suitable for use in dusty industrial environments.
