The Xingdong DC Axial Fan 4010 (40×40×10mm) is a compact cooling solution specifically designed for routers. With the widespread adoption of Wi-Fi 6/7 technology, router chip power consumption has increased to 10-15W. Under high-load scenarios such as multi-device connections and 4K video transmission, if the main control chip temperature exceeds 85℃, it will trigger frequency throttling, leading to increased network latency or even network interruption. This fan, with its precise adaptation, efficient heat dissipation, and intelligent temperature control, is an ideal choice for ensuring stable router operation.

**Ultra-thin design, non-destructive installation**: The fan adopts a standard 40×40×10mm size, and its ultra-thin 10mm thickness allows for easy embedding into the narrow space inside the router. It supports side mounting, inverted mounting, and other installation methods without altering the original airflow structure.

**Efficient heat dissipation, powerful performance**: Airflow reaches 4.48-6.40 CFM, air pressure is stable at 2.32-3.31 mmH₂O, and the speed range is 4200~6000 RPM. Optimized blade angle and spacing, employing airfoil blades and a streamlined airflow design, resulting in a 20% increase in airflow efficiency and a 15% increase in air pressure compared to similar products. Real-world testing shows it can reduce the router's main control chip temperature by over 20°C, effectively resolving overheating and frequency throttling issues under high loads.

**Intelligent Temperature Control, Quiet Operation**: Supports PWM intelligent speed control, automatically adjusting the fan speed based on chip temperature—running quietly at low speeds under light loads (noise level as low as 21.1 dBA) and providing full-speed cooling under high loads. Precision dynamic balancing (vibration value ≤0.05mm) combined with optimized bearing design ensures uninterrupted operation even at night.

**Industrial-Grade Reliability, Worry-Free Operation Around the Clock**: Operating temperature range covers -10°C to +70°C, adapting to various environments. Available in both oil-impregnated bearing and dual ball bearing versions—the ball bearing version supports 24/7 continuous operation with a lifespan of up to 50,000 hours, meeting the long-term stability requirements of home and enterprise routers. Power consumption is only 0.12A (5V), saving 30% energy compared to traditional fans. **Flexible Selection, Multi-Scenario Adaptability:** The fan is available in 5V, 12V, and 24V versions, allowing users to choose flexibly based on their router's power system. An optional IP54 dustproof and waterproof version is available, suitable for router deployments in special environments such as factories and warehouses.

In summary, the Xingdong DC Axial Fan 4010, with its ultra-thin design, efficient heat dissipation, intelligent temperature control, and industrial-grade reliability, effectively solves problems such as overheating and frequency throttling, and network interruptions caused by insufficient heat dissipation in routers. It is widely used in high-performance home routers, enterprise-level gateways, and other scenarios.
