The 1804 square cooling fan provides a reliable active air cooling solution within an extremely compact size of 18mm square and 4mm thick. It supports 5V or 3.3V low-voltage DC power supply, boasts extremely low power consumption, and can be directly driven by a battery. Utilizing a silent hydraulic bearing, its operating noise is below 20dBA, making it an ideal choice for controlling temperature rise and ensuring performance in next-generation electronic devices such as TWS earphones, smart wearables, and micro IoT terminals.<\/h4>\n

Ultra-low power consumption, worry-free battery life<\/h3>\n

\u2013 5V operating current is only 0.05A, power consumption is 0.25W, which has virtually no impact on the battery life of battery-powered devices.<\/p>\n

Quiet operation, imperceptible performance<\/h3>\n

\u2013 Full-speed noise is below 24dBA, and at low speed it is only 18dBA, even lower than the background noise in a quiet environment.<\/p>\n

Designed specifically for miniature heat sources<\/h3>\n

\u2013 The generated concentrated airflow can directly blow on tiny heat sources such as SoCs and sensors, effectively reducing local junction temperature.<\/p>\n

Brushless motor drive:<\/h3>\n

Reduces electrical sparks, improves reliability, supports PWM speed control, and is suitable for heat dissipation or airflow control in precision electronic equipment.<\/p>\n
