How to choose a DC cooling fan correctly?
When choosing a DC cooling fan, many people simply look for a few manufacturers, and then compare the prices to decide, but when choosing a DC cooling fan, you can’t just look at the price. The following DC cooling fan manufacturer-Ruiapple will teach you how to choose a DC cooling fan correctly.
 
1. Listen to the noise: DC cooling fans with the same speed, the same voltage and the lower the noise are better, because the low noise is mainly related to the fan blades, bearings, oil products, assembly structure, etc. The better the shape of the fan blade is designed, the greater the air flow rate and the lower the noise; the higher the accuracy of the bearing, the smaller the friction between it and the shaft core, the more accurate the size matching, and the lower the noise of course; If it is low, it means that the friction is small, the life of the bearing and the shaft core will be longer, and the life of the DC fan will also be longer.
 
2. Look at the current: same speed, same voltage, same air volume. A DC cooling fan with a small current is better. Because the smaller the current, the smaller the fan loss, that is, the lower the power consumption. The main reason for the lower power consumption is the product's strong magnetic permeability, good motor enameled wire loss, and high copper content. D lubricant has high activity.
 
3. Vibration measurement: a fan of the same specification and speed, a small vibration DC cooling fan is better, a DC cooling fan is a high-speed machine, there must be vibration, no manufacturer can guarantee that there is no vibration, the greater the vibration The smaller the better, the smaller the vibration, the smoother the fan will run, the smaller the loss of the bearing and the shaft core, the less oil volatilization or the wear of the balls, and the longer the life span.
