Ways to reduce the noise of radiator fans

Dislike your radiator noise too much? There's no way to solve it? Is there any new way to solve the noise caused by the fan?
　　
Let's start by looking at why the noise is generated.

1, because the fan's bearing quality is not good, or fan blades uneven weight, causing vibration;

2, because the fan, radiator fin engineering design imperfections caused by wind resistance is too large;

3, fan speed is too high.

Workaround:

By lowering the speed of the radiator fan, can greatly reduce the noise, but the problem is caused by the reduction of air volume and wind pressure, or by increasing the diameter of the fan to reduce the speed without reducing (or increasing) the purpose of the air flow, through better engineering design, change the shape of the fan blades, change the shape of the fins, So as to reduce the noise.

At present, many large fan products for us to choose from, for example, TT's 120mm fan of the great typhoon, cool extreme wind will be.

There is also the purpose of silencing the cool extreme Black Hawk fighter by changing the shape of the fan blades and fins.
　　 　　

Of course, there are more special ways to reduce noise, such as the Kyushu Rmoe 775 is the use of exclusive DVT technology to reduce the vibration of the fan caused by the resonance and noise. DVT technology namely, using four rubber columns instead of the usual screws and Kazilai, the fans are fixed on the radiator so that the fans do not contact the fins directly, while the added rubber column just acts as a cushion, and the hanging fan design is designed to minimize the noise.
　　
In fact, similar to the fixed way rubber column has been in the IBM and other brands of server fan to the application, has not walked into the lives of our ordinary people, Kyushu, the winds brought us a new experience.

Through the above mentioned solution can greatly solve the problem of our radiator noise. We pay attention to the PC's working environment, but also pay attention to our own living environment, the noise to a minimum.
