Two types of cooling fans, 4010 cooling fan and 4020 cooling fan, which are more widely used in the market, some customers may not know these two fans.
Where is the main difference
1. Size: The thickness of the 4020 cooling fan is 20mm, while the 4010 cooling fan is 10mm
2. Power: The power of the 4020 cooling fan can be higher
3. Air volume: the air volume of the 4020 cooling fan can be made larger
4. Mute: 4010 cooling fan is relatively quieter
5. Cost: 4010 cooling fan cost is lower
6. Quality: 4020 cooling fan quality is better controlled
