PC Fan NOCTUA NF-A14 industrial PPC-24V-2000 PWM IP67 Q100:The Noctua NF-A14 PWM fan offers the power of seven blades in an integrated 140mm diameter rotor. The blade speed reaches 2000RPM, which is the ideal rate for industrial applications. The fan is connected to the motherboard via a 4-pin connector. It also offers an unprecedented 150,000 hrs (17 years) of trouble-free use. All of this is combined with outstanding performance, exceptionally quiet operation and many great features that will be appreciated by true computer enthusiasts.Key Features of the NOCTUA NF-A14 (2000 PWM)Maximum speed of 2000RPM - support for automatic controlIP67 (protection against moisture and dust)Low noise level: 31.5dBConnects via a 4-pin connectorGuaranteed life over of 150,000 hrsDesigned for use in industrial applicationsDurable Processing & SCD Function for Slower Operation at Low Fan SpeedsIn order to achieve maximum performance, this fan has been made using the highest-quality materials. The bearings are seated in a cap which is made entirely of brass. This ensures, among other things, a long service life and low levels of wear. The NOCTUA NF-A14 also supports fully automatic speed control. One of its main advantages is the Smooth Commutation Drive (SCD) control system, that eliminates undesirable jumps and delivers quieter operation, especially at slower rotation speeds.Additional Information:Maximum Power Consumption:2.4WMaximum Current Consumption:0.1APower:24VLifetime:>150,000 hrsConnector:4-pole with PWM control
