When we choose a cooling fan, there are mainly two different fans, one is a DC fan, the other is an AC fan, which one is better, let us share together the characteristics of these two fans 1. Electricity Method: AC fan can be directly connected to mains power such as 220V, 110V, etc. The DC fan needs to be rectified and transformed from the mains to work, such as DC 12V, 5V and so on. 2. Service life: AC fans with similar bearings and DC fans have no significant difference in service life, mainly depending on the type of bearing. 3. Air volume: DC fans with the same specifications (such as 12038) have longer blades and higher speeds. It can be higher, and the air volume of the DC fan will be larger in comparison. 4. Efficiency: The use efficiency of the DC fan is low. 6W, and the air volume is even greater. 5. Cost: When it is convenient to get power, the DC fan of the same specification is cheaper than the AC fan. 6. Safety: The AC fan is used because of the use of two single fans. The mains power is a dangerous voltage. If you accidentally touch it, it will be life-threatening. The 48V DC fan is also safe.
