cooling fan in the chassis will be set to air suction or blowing mode according to the installation position. Generally speaking, the top and rear fans of the chassis will use blowing mode, and the front of the fan will face the inside of the chassis. At this time, the RGB fan will be at the best display angle, but the fans on the front, side and bottom of the chassis are basically in air suction mode. The back of the fan faces the inside of the chassis. The RGB light on the fan faces the outside of the chassis, which looks strange. The Yaoying SWAFAN series RGB fans launched by Thermaltake recently solved this problem very well.
Yaoying SWAFAN RGB fan comes in two diameters: 12cm and 14cm. It is Tt's first fan with an alternative fan design. Unlike traditional fans, it has two alternative fan blades. Users can freely adjust the direction of the airflow according to their needs, without sacrificing the gorgeous RGB lighting effect. The multifunctional design and convenience allow users to no longer be restricted.

packaging box shows the characteristics of the two fan blades equipped with using pictures. The black-label fan blade is a normal blower fan, while the silver-label fan blade is a suction fan. This fan can change the flow direction of the wind by changing the fan blade without changing the installation direction.
Yaoying SWAFAN 12 RGB fan adopts hydraulic bearings and a unique 9-blade design, PWM control, with a speed between 500 and 2000 RPM, and a lifespan of 40,000 hours (25℃). The overall dimensions are 120mm x 120mm x 25mm, the maximum air volume of the black and silver blades is 53.02 and 54.85 CFM, the maximum air pressure is 2.58 and 2.19 mmH2O, and the noise values are 30.5 and 36.5 dB(A), respectively. The maximum motor current of the
fan is actually 0.7A, but the official specification given by the Yaoying SWAFAN 12 RGB fan is rated current .27A. It is obvious that Tt limits the output power of the motor to achieve the purpose of speed limit and noise reduction.
The fan is installed by default with a black label hair fan blade, and the silver label suction fan blade is placed in the packaging box as an accessory. Players in need can change it themselves. You can see that the tilt directions of the two fan blades are different. Through the two different fan blades, the Yaoying SWAFAN 12 RGB fan can achieve the flip of the wind direction without changing the motor rotation direction.
The replacement of the fan blade is also very simple. Push it hard with your fingers and then insert the one you want to change. In addition to changing the direction of the airflow in the non-moving fan frame, this kind of fan blade can also easily remove the fan blade and rinse it directly with water. The cleaning method is much more convenient than other fans.
is different from other fans using 3-Pin or 4-Pin and ARGB cable. Many Tt fans use something similar to the motherboard USB 2.0 interface. The advantage is that one wire can complete the work that can only be completed by two wires of other fans. The disadvantage is that you must use Tt's fan dock. In fact, it is not convenient to connect. There is also a lubricant in the accessories. Unplugging and inserting the fan blades will cause lubricant to lose, and lubricant needs to be added in time.
fan lighting effect and speed need to be controlled by TT RGB Plus 2.0 lighting effect software. The software does not automatically recognize the fan model of , and players need to choose by themselves. The lighting effect of the Yaoying SWAFAN 12 RGB fan is indeed quite good. 30 LEDs form two internal and external apertures, and coupled with the light guide fan blades, almost the entire fan is luminous. The software provides a variety of lighting effects to choose from. Players can also choose to use the synchronization line to synchronize the fan with other lighting devices on the motherboard.
measured data
In this Tt Yaoying SWAFAN 12 RGB fan test, we need to conduct detailed tests on the maximum air volume, maximum static pressure, effective air volume installed on air cooling, water cooling installed on water cooling , effective air volume of simulated chassis and noise tests. Therefore, we need professional testing equipment. In fan testing, the data comes from the air volume and air pressure test device made by Super Energy Network. This test device is prepared according to relevant national standards and ISO standards. The air volume and air pressure of the fan are measured by multi-nozzle/-hole plate of the pipeline test air chamber, as well as the air volume under different system impedances (normal cold discharge, ordinary tower radiator), and the instant speed of the fan is monitored through the speed tester, and the noise value under full speed of the fan and the common cold discharge are measured in a specially made silent cabinet.
Our air volume and air pressure test device
Wind pressure and air volume test
Actual test Yaoying SWAFAN 12 RGB fan uses black standard forward fan blades with a maximum static pressure of 2.67 mmH2O, and the maximum air volume is 55.8CFM, which is not much different from the official nominal value. Its air volume is 32.1CFM installed on air cooling, 26.6CFM installed on cold discharge, and 51.1CFM installed on simulated chassis. The silver label reverse fan test results in a maximum static pressure of 2.03 mmH2O and a maximum air volume of 57.3CFM. The static pressure of the silver label fan is slightly lower than that of the black label, but has a higher air volume.
In order to facilitate horizontal comparison, we have also added a performance data under the same noise, that is, when the fan is installed in the cold row, it adjusts its noise to a fixed value (38.8dBA noise at 30cm). Of course, the Yaoying SWAFAN 12 RGB requires software to adjust the speed. When using the black label fan, the speed drops to 1470RMP and the air volume is 16.1CFM. If using the silver label fan, the speed will be reduced to 1540RPM and the air volume is 15CFM. For comparison, the air volume of the Owl NF-F12-2K under the same conditions and noise was 21.2CFM.
If the air volume, wind pressure, and system impedance are still relatively vague, you can refer to our popular science article "Real understanding of the air volume and wind pressure of cooling fans".
It can be seen that the maximum air volume of the silver label fan blade is indeed larger than that of the black label fan blade. When installed on the air-cooled radiator, the air volume of the silver label is still larger than that of the black label, but when installed on the cold radiator, the black label fan has a larger air volume. It is estimated that the resistance of the cold radiator is greater for the silver label fan blade with lower static pressure.
noise test
noise test scene is a sound silence room specially created by us. The lowest ambient noise is about 15 decibels. The fan is located in the center of the room. The distance between the noise meter and the fan suction surface is 30cm.
After testing, the Tt SWAFAN 12 RGB fan has a silver label fan blade that is more noise than the black label fan blade, and it is much higher. However, when they are installed on the cold row, the noise between the two will be similar, because the silver label uses the air suction mode, which produces lower noise than the single fan. The black label fan blade with the blowing mode is more noise than that of the single fan. The test of silver-label fan blades with air-cooled radiator has not been tested, because in fact, even if someone installs this fan on air cooling, it is a combination of blowing air and one suction air, and it is not very meaningful to measure one suction alone.
summary
In fact, from the introduction and positioning of Tt on the Yaoying SWAFAN 12 RGB fan, it is not a fan with the main performance. However, from the test results, the air volume and static pressure performance of the SWAFAN 12 RGB fan is still within the mainstream product range, but in terms of noise, the pre-installed black label fan blades perform quite well. The maximum air volume of 55.8CFM and idling noise of 43.4dBA for a single fan. In comparison, the maximum air volume of 58.3CFM and idling noise of 43.5dBA for the Owl NF-AP12 redux-1700 is 58.3CFM and idling noise of 43.5dBA. The main selling point of this fan is of course its lighting and replaceable fan blade design. There are fewer fans with detachable fan blades on the market. Fans like Yaoying SWAFAN series fans are not only removable, but also have two types of fan blades that can be replaced by suction and blower. This ensures that the front of the fan is always facing the inside of the chassis, presenting the best lighting effect. Combined with the TT RGB Plus 2.0 lighting software, a beautiful chassis lighting system can be created. In addition, the detachable fan blade has an advantage, that is, the fan blades can be removed separately and washed with water, which is much easier to clean than other fans.
Of course, Tt Yaoying SWAFAN 12 RGB fan is in three groups, and it is also equipped with three fan blades and a fan control box. The price is not cheap. Each group costs 799 yuan, while the 14cm version is 849 yuan. It is really beautiful to install this fan into the chassis. It is equipped with two fan blades to make it easy to apply to various environments. There is no need to sacrifice beauty for the wind direction. It is suitable for those who want to create a perfect chassis RGB lighting system.
