Koolance Inc. is known as a manufacturer of liquid cooling systems and related components. Among the latter there is the 120mm Koolance FAN-12025HBK. It is shipped as OEM product without any packaging or accessories.
The Koolance FAN-12025HBK looks ordinary with its black frame and glossy black 7-blade impeller:
Its form-factor is 120x120x25 mm and its weight is 143 grams. It is manufactured in China and costs $10. Its warranty period is 1 year.
The broad blades have a big angle of attack and a sharp front edge. The interior surface of the frame is beveled, but the edges are somewhat smoothed out.
There are bushings in the corners of the frame, so you won’t be able to fasten the fan using the openings on the interior surface. The impeller and motor are 113 and 43 mm in diameter, respectively.
The Koolance FAN-12025HBK has a constant speed of 2600 RPM and it cannot be regulated in any way. The specs promise an air flow of 107.6 CFM and a static pressure of as high as 5.4 mm of water at 32.8 dBA of noise.
The Koolance FAN-12025HBK runs on a conventional dual ball bearing. Although without any newfangled nano technologies, it is likely to serve for a long time. The specs do not declare its service life, however. As for electrical parameters, the fan needs 3.36 watts of power at 0.28 amperes.
The cable is about half a meter long. There is no PATA power adapter in the box. That’s all we can tell you about this model.
