NOCTUA NF-R8 PWM

Fan Noctua NF-R8 PWM is the successor to the highly popular model that helped create cutting-edge products listed brand reputation. Users still particularly appreciate its quiet operation combined with high cooling performance. The new version includes a special PWM control company Noctua, which provides automatic speed control at very low power consumption. The fan is also equipped with high-end SSO bearings, which provide unprecedented median uptime in excess of 150,000 hours (17 years!).
Innovative PWM control IC with SCD
Noctua NF-R8 PWM supports fully automatic speed control. Its main advantage is the smooth transmission system control pulses (Smooth Commutation Drive - (SCD)), which eliminates unwanted jumps and delivers quieter operation especially at lower rotation speed. The fan also comes with resistance Low-Noise Adaptor (LNA) for reducing the maximum speed from 1,800 to 1,300 rev/min. The resistance can be used both for fixing speed 1300 rev/min and a reduction of the maximum speed 1300 rev/min.

Extensive support connection
The fan is equipped with a short cable with a length of twenty centimeters. Using the supplied extension cable 30centimetrového, but connect it to almost any large enclosure. Both cables are fully braided and Y structure allows to connect a second NF-R8 PWM to the same header for automatic speed control.

SSO bearings
Integrated SSO system combines the proven concept of hydrodynamic bearings with an additional magnet that supports self-stabilization of the rotor axis, flights proven proprietary bearing Noctua will provide extremely quiet operation and excellent long-term stability.
