How to solve the noise of the cooling fan of the mining machine chassis?

The current mining machine case has high power and high temperature. Therefore, the cooling fan is required to have a large air volume. Therefore, relatively, the cooling fan has a large current and power, and the noise is also large. What should I do? If the speed of the 7-blade cooling fan of the original mining machine reaches 6000 rpm, the air volume is 240CFM, and the power is 2.4A, the noise is large, and the 11-blade cooling fan is used to achieve the same high air volume, but the speed is only 4300RPM, so that the fan runs The scream is smaller. In addition, in order to reduce noise, the PWM speed control function can be adjusted. When the frequency is high, the speed is high, and vice versa, the speed is low. This can also reduce the noise of the mining machine during heat dissipation. You are welcome to visit the heat dissipation classroom and news center of the cooling fan manufacturer again.
