AC or DC fan NMB Minebea

Selecting between DC Fans and AC Fans:

First, consider whether you want DC fans or AC fans. In the past, the higher cost of DC fans led to the almost exclusive use of AC fans. Now that this price differential has disappeared, the many advantages of DC fans make them the best choice. One advantage of DC fans is longer life. Another is almost 60% less power consumption than AC fans. According to industry experts, a 10°C increase in fan temperature can reduce its life by as much as 20,000 hours.

Another selection factor is that the speed of DC fans is directly proportional to voltage, so it can run at the speed required for adequate cooling. However, usually DC fans runs at less than maximum speed, creating less noise, and using less power.
