How to detect the quality of 24V cooling fan

24V heat dissipation fan is commonly used voltage fan, with more is 5V, 12V, 24V, 48V, etc., according to the different choice of voltage in different industries, then how to buy 24V heat dissipation fan detection is good or bad ?

1, the detection of 24V heat dissipation fan is good or bad to see whether the fan frame leaf is strong, the appearance design is coordinated, edges and corners are clean, see the raw materials.

2. During operation, check the jitter of the fan. If the jitter is too large, it indicates that the design of the fan is faulty.

3, good fan current is small, high speed, this can see the parameters.

4. Check the appearance of the fan and then check whether the power cable is energized.

5. Finally, check whether the motor rotor shaft is active.

Choose 24 v find on a cooling fan manufacturers, basically there is no problem, good cooling fan manufacturer is specialized after-sale, so don't worry about whether the fan will have a problem, so when the choice must pay attention to see the strength of the manufacturer, whether to have complete qualification, according to the above to confirm the stand or fall of fan, also can choose the good fan.
