Computer fans are already quite mature products. In addition to those that focus on large air volume, high wind pressure, high speed, and those that emphasize silence, they also play with colors, from the casing, bearings to RGB lights, and magnetic attraction. Fans connected in series, besides these, how else can the fans be used?
be quiet! from Germany gave another answer. Through modular structure and adjusting the distance between the fan and the frame, it can provide high air pressure and increase the air volume while maintaining silence, and optimize the water cooling radiator. , radiator, chassis and other different installation purposes, this is the Silent Wings 4 series fan that I will introduce today.
Product specifications introduction
In fact, be quiet! has previously launched a new modular structure Silent Wings 4 fan, and this time it has added a new white version, including PWM High-Speed White, PWM White for Silent Wings 4, and PWM White for Silent Wings Pro 4 , and both provide 120mm and 140mm fans in two sizes to choose from.

Silent Wings 4 PWM White and PWM High-Speed White fans combine all the advantages of being almost silent and ultra-high-efficiency. By shortening the distance between the blade edge and the fan frame, and using the funnel-shaped air outlet on the fan frame, it can produce a larger wind pressure and maintain lower noise, and further reduce vibration through the shock-proof rubber buckles at the modular corners of the frame.
In the motor part, the 6-pole fan motor is matched with three AC inverters to reduce operating vibration and power consumption, and its maximum noise value is only
36.9 dB (A), the fan is almost silent when running at medium speed, and is equipped with advanced fluid dynamic bearings (FDB) to bring ultra-long service life. The original manufacturer indicates that the use time can be up to 300,000 hours, which can be regarded as a demonstration of its own products. High confidence.
Silent Wings Pro 4 PWM White is based on the use of water cooling radiators and radiators to optimize performance. Under the same structure as Silent Wings 4, it additionally provides a quick switching function of fan speed and also provides modularization. At the corners, different buckles can be selected according to installation needs.
The following is a reference specification of the three fans. It can be noted that whether it is Silent Wings 4 or Silent Wings Pro 4, it can maintain a very low noise value under the premise of large air volume and high wind pressure. The Silent Wings 4 PWM version is extremely quiet. There is still a good air volume at 100% speed. The noise value of the 120mm fan is only 18.9 dBA at the maximum speed of 1,600 rpm. The noise value of the 140mm fan is 13.6 dBA at the maximum speed of 1,100 rpm. It reaches the silent level and is very suitable for use as a case fan.
Silent Wings 4 PWM High Speed and Silent Wings Pro 4 have higher fan speed, air volume, and air pressure. Compared with the PWM version, they have about 50-60% more air volume and more than double the air pressure. They are very suitable for use. Installed on water cooling radiator or air cooling radiator.

Next, we will introduce Silent Wings 4 High Speed and Silent Wings Pro 4 in detail to see the design and features of these two fans.
Product design and features
The picture on the left is Silent Wings Pro 4 140mm PWM, and the picture on the right is Silent Wings 4 WPM High Speed.
The gap between the fan and the frame is quite close, which provides better performance for wind pressure.
There are three speed gears on the back of Silent Wings Pro 4 that can be switched. From left to right, they are medium speed (M), high speed (HS), and ultra high speed (UHS). The corresponding speeds are 1600 RPM, 2500 RPM, and 3000 RPM. Since The switch is set behind the fan, so players are advised to select the mode before installing the machine.
The fan itself does not have RGB lighting or other luminous effects, so you only need to connect the PWM 4-Pin braided cable to power the fan. Players can also adjust the fan curve through the BIOS or software.
Silent Wings Pro 4 (left) can manually switch the speed directly on the back of the fan
PWM 4-Pin using braided wire, fully whitened.
On the frame of the fan frame, in addition to the engraved words “be quiet!”, there is also a clear fan blade rotation mark, so there is no confusion when installing the fan and the wind direction is reversed. There are also modular buckles on both sides of the corners of the fan frame that can be pressed and removed.
Silent Wings Pro 4 PWM White comes with 3 buckle installation options. The special corner buckles for water cooling radiators are pre-installed. Silent Wings 4 White comes with shock-proof rubber buckles pre-installed and can be used for water cooling radiators and radiators. plastic fasteners. Players can use the included plastic rivets or use tapping screws to install it on the chassis or radiator.
The left side of the picture shows Silent Wings 4 and the right side shows Silent Wings Pro 4. You can see the difference between the pre-installed and included buckles.
Summarize
be quiet! The new white Silent Wings 4/Silent Wings Pro 4 series fans still maintain their excellent heat dissipation and quietness capabilities. They achieve higher air pressure performance by shortening the distance between the fan blades and the frame, and the modular frame passes through Push Pin method can quickly replace the buckles of different materials, and can be installed on the water cooling radiator, radiator or chassis, making it more flexible and convenient to use.
In addition to the white fan revealed this time, there is also an all-black version to choose from. For those who like a low-key and want to build a computer with both heat dissipation and quietness, Silent Wings 4 PWM High Speed and Silent Wings Pro 4 PWM provide players with a pure large air volume, A good choice for fans with high wind pressure and no light pollution.
