be quiet! BL109 Pure Wings 3 PWM High Speed 14cm Case Fan Black Ultra Quiet Fan

Product details

Pure Wings 3 140mm PWM high-speed are the perfect addition to demanding PCs with extraordinarily high performance and progressive features such as a speed-regulating closed loop motor. Innovative closed loop motor keeps the rpm no matter the resistanceOptimized fan frame for outstanding performance on radiatorsNewly designed fan blades and re-arranged angle for extraordinary air pressurePure Wings 3 140mm PWM high-speed can be operated with very low minimum rpm for very quiet operationLong life rifle bearing gives an operating lifetime of 80,000 hoursProduct conception, design and quality control in GermanyInnovative TechnologyClosed loop motor for persistent rpmPure Wings 3 140mm PWM high-speed features a closed loop motor. This technology is comparable with the cruise control in cars.  When working against resistance, for example a fan grill or radiator, fans spin slower as a result. The closed loop motor technology constantly monitors the current fan speed and increases it to the target rpm, if necessary. As a result, Pure Wings 3 140mm PWM high-speed always operates at the desired speed, no matter the resistance. Optimized to the MaxFor unprecedented air pressure in its classThe fan frame outlet is newly designed to minimize air leaks. This benefits especially the radiator performance of Pure Wings 3 140mm PWM high-speed. To reach even higher performance, the fan blades are optimized as well: Their angle is adjusted to achieve even more air pressure, adding up to the extraordinary performance of Pure Wings 3 140mm PWM high-speed. For Radiators and HeatsinksFan blades optimized for high pressureWith a remarkably high air pressure of up to 2.44mm/H2O, Pure Wings 3 140mm PWM high-speed  is the best choice for water-cooled and air-cooled systems alike. The 9 airflow-optimized fan blades provide enough air pressure to make this fan work great even in demanding configurations. Iconic DesignStreamlined look makes it an instant timeless classicPure Wings 3 140mm PWM high-speed trims all the fat. Every part and single detail contribute to the functionality and uncompromising performance. This has also been considered in the design of the fan. All outlines and angles serve a purpose, making Pure Wings 3 140mm PWM high-speed a timeless classic and elegant addition to every gaming PC. Rifle Bearing TechnologyMakes Pure Wings 3 a long-lasting companionPure Wings 3 140mm PWM high-speed is built to last. With the proven rifle bearing technology, on average, this fan offers a lifespan of a 80,000 hours.Specification:Type: 14cm Case FanFan Connector(s): 4-pinInstallation: ScrewsColour: BlackLED Lighting:-Weight: 188g (incl. fixed cables)Fan Dimensions: 140 x 140 x 25 mmFan Controller: PWMRotation Speed: 1800 RPM @ 100% PWMFan Bearing: Rifle BearingAir Flow: 72.2 CFM @ 100% PWMNoise level: 30.5 dB(A) @ 100% PWMPower:Rated Voltage DC: 12VOperating Voltage DC: 5 - 13.2VCurrent consumption: 0.12ASafety current: 0.50AInput power: 6WMTBF: 80,000 hoursPackage Type: RetailPackage Weight: 0.1900 kgWarranty: 3 YearsFull Box Quantity: 72
