Is a power supply with a temperature-controlled fan a good power supply？

There are two types of cooling fans for switching power supplies: general fans and temperature-controlled fans.Is a power supply with a temperature-controlled fan a good power supply? The answer is: not necessarily.

The specific judgment depends on the use of the power supply and the place of use.Temperature control fan means that when the power supply starts to work and reaches a certain temperature, the temperature control probe recognizes the switch and closes, and the fan begins to operate at high speed;When the temperature does not reach a certain level, the fan operates at a low speed or does not operate.This helps to protect the power supply that has been operating at low power, or the power supply that works in high temperature and harsh environments,For example, the power supply used in the machine equipment stepper motor output power size is unstable, sometimes empty and sometimes full load, with the temperature control fan power supply is better.If the power supply is used in the case of continuous high temperature or continuous load LED lighting, the fan must be started at any time, continuous heat dissipation, otherwise it will burn out the components because the temperature is not identified by the temperature control probe for a long time, then the temperature control fan has no meaning to exist.

Therefore, it is not necessarily a good power supply with a temperature-controlled fan.
