With the advancement of technology, DC cooling fans have become widely used in our daily lives—for example, in commonly used laptops and computer systems—both of which rely on cooling fans. During use, DC cooling fans inevitably encounter some minor issues. So, when a DC cooling fan experiences a small malfunction, how should we go about resolving it? The following are specific solutions for common DC cooling fan failures.
1. During use, the DC cooling fan has suddenly become unusually loud—sometimes even louder than the sound of the chassis power supply. Solution: This issue is usually caused by dried-up lubricant in the fan or excessive dust buildup on the fan. All we need to do is separate the heatsink from the fan, clean the fan thoroughly, let it dry completely, and then apply a small amount of lubricant.
2. The fan shifted its orientation during use. Solution: In this case, the fastening clip that secures the fan must have been damaged; replace it with a new one. 3. When the fan is rotating, you’ll hear a rattling impact sound. Solution: This issue is caused by the fan coming into contact with the data cables. Use rubber bands to bundle and separate the data cables. The above are solutions for common faults in DC cooling fans. Of course, the issues mentioned above are those we typically encounter most often—and they’re also problems that you can usually fix yourself. If you’d like to learn more technical guidance, please stay tuned for Jiangshan Lai.

Advantages and Applications of Oil-Bearing DC Fans
The pivot joint is fixed at the position of the motor stator base, ensuring an appropriate gap between the rotor and the stator. Of course, there must also be a clearance between the shaft core and the bearings to prevent the shaft core from becoming locked and thus unable to function. The stator structure of the motor—hereafter referred to as the "stator"—is designed in such a way that, once power is supplied, an induced magnetic field will be generated between the rotor and the stator. The control circuit then drives the electric fan motor into operation. Therefore, in the conventional fan motor design, as long as the fan rotor, the motor stator, and the drive circuit work together via the pivot joint between the shaft core and the bearings and through magnetic field induction, the motor can operate effectively.
