What are the key specifications of a 5V DC brushless fan?
Key specifications of a typical 5V DC brushless fan include:
- Voltage: Operates at 5 volts.
- Airflow: Measured in cubic feet per minute (CFM), indicating cooling efficiency.
- Speed: Rotational speed in RPM (revolutions per minute).
- Noise Level: Measured in dBA, indicating how loud the fan operates.
- Bearing Type: Common types include sleeve or ball bearings, affecting longevity and noise.
These specifications help users choose the right fan for their specific cooling needs.
Why is brushless technology important for cooling?
Brushless technology is important for cooling because it minimizes mechanical wear and tear, resulting in quieter operation and longer lifespan compared to traditional brushed motors. This technology also allows for more efficient power usage, making it ideal for low-power devices like mini PCs.
How does airflow impact cooling efficiency?
Airflow directly impacts cooling efficiency by determining how effectively heat is dissipated from components. Higher airflow (measured in CFM) means more air is moved across the heatsink or CPU, enhancing heat transfer and maintaining lower temperatures under load.Chart: Airflow vs. Cooling Efficiency
| Airflow (CFM) | Temperature Drop (°C) |
|---|---|
| <10 | <10 |
| 10 – 20 | 10 – 15 |
| >20 | >15 |
