General Information The high quality Noctua fans are now available with PWM control. The NF-F12 PWM has all the features of the well known models by Noctua and some new highlights like the Focused Flow? System. Designed for superior performance in pressure demanding applications such as heatsinks and radiators, the Focused Flow? frame features eleven stator guide vanes that straighten, channel and focus the airflow, which allows the NF-F12 to rival the performance of conventional fans running at much faster speeds. Noctua?s Stepped Inlet Design is an advanced aerodynamic design measure first introduced with the NF-F12 fan. By adding turbulence to the fan?s influx, the Stepped Inlet Design facilitates the transition from laminar to turbulent flow. This measure has an effect similar to the dimple structure of a golf ball in so far as it leads to better flow attachment to the frame, which allows the impeller to suck in more air and hence improves overall airflow efficiency. The self-stabilising oil-pressure bearing (SSO-Bearing) system has always been at the heart of Noctua?s award-winning premium fans. Silent enthusiasts and industry clients alike swear by its proven, time-tested quality. SSO combines the proven concept of oil-based hydrodynamic bearings with an additional magnet that supports the self-stabilisation of the rotor axis. Due to the axis being stabilised by the magnetic field, Noctua?s SSO Bearing achieves higher precision and better longevity than conventional ball-, sleeve- or hydrodynamic bearings. Noctua?s custom-designed NE-FD1 is a next-generation PWM fan driver IC that integrates Smooth Commutation Drive (SCD) technology for quieter operation and allows for ultra-low power consumption. Its superb linearity and security features such as locked rotor or reverse voltage protection make it an ideal driver IC for premium-class PWM fans. Most conventional PWM fan driver ICs put out square signals that cause sudden torque impulses. These impulses can cause minute deformations of the entire fan structure which lead to audible ?clicking? noises that are especially noticeable with many common PWM fans running at slower speeds. Adopting Noctua?s Smoot Commutation Drive (SCD) technology, the custom designed NE-FD1 PWM IC slows down the slew rate of the output signal in order to give a smoother, less sudden torque impulse. This way, PWM switching noises can be effectively suppressed and the fan runs even quieter, especially at low speeds. |
