The Noctua NF-A9 is a 12 volt axial fan with a chrome black colour. The dimensions are 92mm x 92mm x 25mm and the fan comes with a colour set to adjust the look. The colour set includes eight black & four blue, red, green, yellow and white shock absorbers. In addition to the colour set, the fan comes with an extension cable and 4 mounting screws.Noctua uses shock absorbers and so-called SSO2 bearings. These are bearings that stabilise themselves by means of oil pressure. Partly thanks to this design, an average Noctua fan can run no less than 150,000 hours, approximately 17 years!
