Swiftech Helix 120 (HELIX-120-BW)
Swiftech specializes in producing components for liquid cooling systems but has one 120mm fan in its product range. It is called Helix 120. According to the official press-release, the fan is optimized for liquid cooling systems and is capable of producing a higher pressure compared to ordinary fans.
The compact white box provides exhaustive information about the fan, including its specifications.
There are no accessories except for mounting screws.
Manufactured in China, the fan costs $9.95. The warranty period is 1 year.
The Swiftech Helix 120 measures 120x120x25 mm; its weight is 159 grams. The white 9-blade impeller contrasts with the black frame.
The crescent-shaped blades are long, thick at the ends and have a sharp front edge. The interior of the frame is flat.
The rims of the interior surface are rounded off. The impeller is 108 mm in diameter; the motor is 41 mm in diameter.
The Swiftech Helix 120 has no kind of regulation, so its speed is constant at 1800 RPM. The fan can produce a static pressure of 2.29 mm of water and an air flow of 55 CFM. The correlation between these two parameters is illustrated by the following chart:
The Swiftech Helix 120 runs on a Z-axis sleeve bearing which is something in between ordinary sleeve bearings and fluid dynamic bearings. It has a groove that allows the lubricating liquid to circulate, improving the service life. So, the specified service life of the bearing is 60,000 hours or almost 7 years of continuous operation. The electrical specs are quite interesting for the rated speed: 0.16 amperes, a low power draw of only 1.92 watts and a startup voltage of 7 volts. The 3-wire cable is 450 mm long.
