![]() So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything. Screw hole spacings and fan sizesĮlectrically, there is no problem doing this - the fourth pin on the fan cable is used purely for PWM control and is not needed in order for the fan to run. Note that the mounting hole measurements shown below are taken horizontally or vertically between the holes and not diagonally. If you know the distance between the fan mounting screw holes but don’t know what fan size to order, please see the following table. If you have any questions about which fan you should order, please don’t hesitate to get in touch. All our fans are 25mm thick unless otherwise stated. #NOCTUA NF S12B REDUX 1200 PC#This isn’t really dictated by customer preference, but more by recent designs of PC cases.Īs for the thickness (depth) of the fan, generally 25mm (1 inch) is by far the most common depth, although smaller fans can have shallower depths such as 15mm or even 10mm. The sizes of all the fans on our website are shown as measured along any one of the fan’s four sides, NOT the distance between the fan’s screw holes! Our most popular fan size is 120mm, followed by 80mm. The size of fan you need will generally be determined by the size of the fan fitting position in your PC case. #NOCTUA NF S12B REDUX 1200 FULL#Like all Noctua fans, the redux edition models feature an MTBF rating of more than 150.000 hours and come with a full six year manufacturer’s warranty.

SSO-BearingĬombining the proven concept of hydrodynamic bearings with an additional magnet that supports the self-stabilisation of the rotor axis, Noctua’s time-tested SSO-Bearing technology has become synonymous with supremely quiet operation and exceptional long-term stability. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at lower speeds. Supporting fully automatic speed control via PWM, the fan uses Noctua’s custom designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. Reducing critical rotor stator interaction, Bevelled Blade Tips permit to combine extended leading edges and a higher blade surface area with quieter operation and thus form a cornerstone of the fan’s outstanding efficiency. The NF-S12B has been specifically designed for high airflow efficiency and low noise in order to provide best results in these so called low impedance applications. Typical PC case ventilation applications require high airflow but only medium static pressure. All redux edition products are industry proven, time-tested models that helped to found Noctua’s reputation as a first-tier supplier of premium grade low noise cooling equipment. The redux product line reissues some of Noctua’s most popular, award-winning models by presenting them in streamlined, accessibly priced packages.
