Thermaltake has unveiled its latest products, the SWAFAN 120 RGB and SWAFAN 140 RGB case fans, designed specifically for use in liquid-cooling radiators. These fans are equipped with easily-interchangeable impellers, each set having a different airflow direction. Although it is possible to simply flip a case fan to alter its airflow direction, this exposes the unattractive backside of the fan hub, including its regulatory markings and protruding wiring, as well as the frame pillars that support the hub. This design guarantees that only the impeller and its visually-pleasing RGB setup face you, which is particularly beneficial when the radiator is sandwiched between two sets of fans in a push-pull setup. The impellers are also swappable, making it simple to clean the fans.
The SWAFAN 120 RGB and SWAFAN 140 RGB fans are available in black or white, and come in packs of three fans, including an RGB controller. These fans are equipped with hydraulic bearings that can last up to 40,000 hours. They have a 9-pin connection that looks like the USB 2.0 headers on the motherboard, which is used for both power and RGB control. Therefore, the included lighting controller serves as a USB 2.0 hub that interfaces with the motherboard through a USB 2.0 header, and also requires a 4-pin Molex for additional power.
Thermaltake has categorized the two impellers that come with the fans as “black labeled” and “silver labeled”. The black-labeled impeller is considered the regular one that moves air through the frame and out of the back of the fan, whereas the silver-labeled impeller is designated for the reverse airflow. The SWAFAN 120 RGB operates at speeds ranging from 500 to 2,000 RPM. In terms of performance, the standard impeller delivers up to 53.02 CFM of airflow at 2.58 mm H₂O static-pressure, and 30.5 dBA noise output. On the other hand, the reverse impeller provides up to 54.85 CFM of airflow at 2.19 mm H₂O static-pressure, and 36.5 dBA noise output.
The SWAFAN 140 RGB shares the same speed-range as the SWAFAN 120 RGB, which is 500 to 2,000 RPM. However, it offers different specifications for its standard and reverse impellers. The standard impeller can push up to 77.6 CFM of airflow at 3.12 mm H₂O static pressure, and produces a noise output of 34.5 dBA. On the other hand, the reverse impeller can deliver up to 71.3 CFM of airflow at 2.59 mm H₂O static pressure, and produces a noise output of 40.5 dBA. It’s worth noting that both fan models’ standard and reverse impellers have differing specifications because of their distinct fan-blade designs.
