Many people may still not know that during installation... Cooling fan What should we pay attention to? We need to avoid the following practices, otherwise it could shorten the lifespan of the cooling fan.
1. Install the fan in reverse, with the fan blades facing downward. If the fan blades are suspended for extended periods during prolonged use, the rotor’s magnetic strength may weaken over time, causing the blades to move closer and closer to the stator of the motor. As a result, the cooling fan might fail to rotate due to poor induction. Fans containing oil are particularly prone to this issue, so structural design modifications are necessary to address it.
2. Either clamp the cooling fan on both sides or insert one screw diagonally into each of the cooling fan’s screw holes—both of these cooling methods can easily cause the cooling fan to resonate with the product, amplifying the noise. If the fan vibrates excessively over a prolonged period, it will adversely affect the bearings and shaft core, reducing the fan’s lifespan.
3. Exhaust cooling has a shorter lifespan than blow cooling, because exhaust cooling continuously draws hot air, keeping the motor constantly in a heat-absorbing state and heating the driver IC inside the motor, which in turn degrades its performance.
