In order to reduce the dead Angle of the cooling fan, we can optimize it by the following methods:

Multi-fan design: Multiple cooling fans are used to ensure that all areas can be adequately covered by air flow. For example, additional fans can be installed on the side of the case to enhance air circulation.

Optimize the position and direction of the fans: Adjust the position and wind direction of the fans to ensure that the air flows through each corner of the chassis. Increase fan coverage especially around hard disk racks, graphics cards, and motherboard components.

Use of efficient motor technology: With the advancement of technology, the application of new motor technologies such as customizable coreless motor, customized micro motor and waterproof dc rotor brush motor greatly improves the efficiency and life of fans. For example, the use of customizable coreless motors not only increases the air volume and pressure of the fan, but also reduces noise and ensures a more stable heat dissipation effect.

Ac cathode motors: In some high-load environments, the use of AC cathode motors can also significantly improve the performance of the cooling fan. This kind of motor provides powerful power while ensuring the reliability of long-term stable operation,But the ac shaded pole motor Price will be higher.
