5. Core Product Features & Advantages

5.1 PWM Intelligent Speed Regulation

The fan integrates independent PWM control circuit. Users can adjust fan rotation speed according to real-time equipment load, reducing power loss and running noise under low-load conditions, realizing energy-saving intelligent heat management.

5.2 Real-time Pulse Speed Monitoring Sensor

Equipped with pulse output sensor, the host system can continuously read real-time fan speed data. It supports automatic fault alarm when fan stalls or malfunctions, improving operation safety of critical IT and medical devices.

5.3 Dual Built-in Motor Safety Protection

Two protection mechanisms prevent permanent motor damage:

Locked rotor protection: Automatically cut off current if impeller is blocked by foreign objects;
Reverse polarity protection: No permanent damage when positive/negative power wires are connected reversely by mistake.

5.4 Reinforced Ribbed Frame for 1U Rack

Unique ribbed plastic frame improves structural rigidity, effectively reduces vibration resonance inside narrow 1U chassis, and perfectly matches standard mounting holes of most 1U servers, network switches and embedded power supplies.

5.5 Long L10 Lifespan & Wide Temperature Adaptability

Adopts high-precision bearing system, L10 service life reaches 30000 hours under continuous 60℃ operation. Stable performance is guaranteed within -20℃ ~ +60℃ wide temperature range, suitable for complex industrial working environments.

5.6 UL94V-0 Flame Retardant Material & Global Certifications

Frame and impeller are made of UL94V-0 flame retardant plastic to meet strict industrial fire safety standards. The fan passes UL, CSA, EN and RoHS certifications, fully compliant with export standards for North America, Europe and other global regions.

6. Main Application Fields

This 40×40×28mm ribbed DC12V low power cooling fan is widely used in high-density heat dissipation equipment:

1U rack servers, network switches, firewalls and communication chassis
