Its standard impeller pushes up to 77.6 CFM of airflow at 3.12 mm H₂O static pressure, and 34.5 dBA noise output while its reverse impeller does up to 71.3 CFM of airflow at 2.59 mm H₂O static pressure, and 40.5 dBA noise output. The SWAFAN 140 RGB offers the same 500 to 2,000 RPM speed-range as its smaller sibling.

The reverse impeller offers up to 54.85 CFM of airflow at 2.19 mm H₂O static-pressure, and 36.5 dBA noise output. For this fan, the standard impeller offers up to 53.02 CFM of airflow at 2.58 mm H₂O static-pressure, and 30.5 dBA noise output. The SWAFAN 120 RGB turns at speeds ranging between 500 to 2,000 RPM. Thermaltake designates the two impellers included with these fans as 'black labeled' and 'silver labeled.' The black-labeled impeller is the 'standard' one that pushes air through the frame and out the back of the fan whereas the silver-labeled one is the 'reverse' impeller that pulls air through the frame. The included lighting controller is hence essentially a USB 2.0 hub that interfaces with the motherboard over a USB 2.0 header, and takes in a 4-pin Molex for additional power. The fans each take in a 9-pin connection that resembles the USB 2.0 headers on the motherboard, which it uses for both power (main function) and RGB control. The fans feature hydraulic bearings rated for 40,000 hours. The swappable nature of the impeller also makes it easy to clean these fans.īoth the SWAFAN 120 RGB and SWAFAN 140 RGB come in black and white color variants, and in packs of three fans that include an RGB controller. This is especially useful when you have the radiator sandwiched between two sets of fans in a push-pull configuration. This approach ensures you have just the impeller and its pretty RGB setup facing you. You could just flip a case fan around to reverse its airflow direction, but that would expose the ugly reverse side of the fan hub with its regulatory markings and wiring sticking out, not to mention the pillars of the frame that hold the hub in place.

These fans come with easily-swappable impellers, and include two sets of them, each with a different airflow direction. Thermaltake today introduced the SWAFAN 120 RGB and SWAFAN 140 RGB case fans optimized for used in liquid-cooling radiators.
