The problems that micro cooling fans are prone to occur in use are noise and crashes. These two situations are particularly obvious. Then there are several reasons for the high noise of the micro cooling fans? The noise of the micro cooling fans we are talking about here is the following two:
1. Mechanical noise
2. The wind of the fan
To solve the mechanical noise of the micro cooling fan, we must start with the material and assembly of the fan. The following reasons will cause the fan to make loud noises.
1. The induction IC touches the magnetic stripe of the fan blade of the micro fan and produces a frictional sound.
2. The motor component of the micro fan-the coil is ground to the fan blade.
3. The size of the assembly structure is incorrect, and the bearing wears the oil ring.
4. The material problem of the bearing and the shaft core will cause noise.
Quality problems: crashes, the motor wire diameter of the micro fan is relatively small, and it is easy to disconnect and cause the fan to not rotate.
Dead point, for low-speed micro-fans, because of the low current and low power, if there is no special design, it is easy to cause poor startup.
When choosing a supplier, customers strictly control the above items. If there is still no way to confirm, and they attach great importance to the quality of the micro fan, choosing a micro fan manufacturer with safety regulations is not an option.
