FRACTAL DESIGN ventilátor 140mm Venturi HF-14 černý

http://www.fractal-design.com/home/product/casefans/venturi-series/venturi-hf-14 The Venturi High Flow Series fans, HF-12 and HF-14, are optimized for low-restriction airflow environments, making them an excellent choice for computer case fans, or other low-restriction usage scenarios. Designed with a variety of performance-increasing and noise-reducing features, these fans can move an amazing amount of air compared to other fans at the same, minimal noise level. The HF-14 comes with two sets of solid vibration-dampening rubber corners: one for standard 140mm fan hole spacing (125mm) and one compatible with the standard 120mm hole spacing (105mm). The Venturi High Flow Series fans are ideal for those looking for a perfect balance between high performance and low noise built from sturdy, high quality materials. Key features Featuring true FDB-bearings, providing silent operation coupled with a long lifespanEquipped with a counter-balanced magnet that reduces the axial tension on the bearingFeatures integrated vibration-dampening corners, made from solid high-quality synthetic rubberDense, sturdy construction, made from high-grade glass fiber reinforced thermoplasticpolymerFan geometry is optimized for a ground-breaking airflow, perfect for low-restriction usage scenarios such as computer case ventilation and low-density heatsinks or radiators.Aerodynamically shaped thin stator struts reduce noise and unwanted turbulenceStrategically placed notches on the blades further reduce and diffuse any humming noise produced when the blades pass the stator strutsThe trip wire technology introduces a micro-turbulent layer that combats elements that negatively affect performance, resulting in quieter operationFeaturing a powerful motor to maintain a reliable speed and a low-speed adapter for reducing the speed without the use of a fan controller140mm fans come with an additional set of vibration-dampening corners are included that lends compatibility with 120mm fan mounts (105mm screw spacing). This enables the use of 140mm fans on many CPU coolers.Available in 120mm and 140mm fan sizes Specifications Fan HF-12 HP-12 PWM HF-14 HP-14 PWM Size [mm] 120*120*25mm 120*120*25mm 140*140*25mm 140*140*25mm Colors available Black blades, black corners, dark grey ("Gunmetal") frame Black blades, black corners, dark grey ("Gunmetal") frame Black blades, black corners, dark grey ("Gunmetal") frame Black blades, black corners, dark grey ("Gunmetal") frame Screw hole pattern 105*105mm 105*105mm 125*125mm 105*105mm 125*125mm 105*105mm Connector 3-pin fan header 4-pin fan header 3-pin fan header 4-pin fan header Bearing FDB FDB FDB FDB Number of blades 9 7 11 7 Rotational speed [RPM] 1400 1800 1200 1500 Acoustical noise [dB (A)] 25.3 31.7 26.5 30.1 Maximum air flow [CFM] 83.4 61.4 118.2 78.1 Maximum air flow [m 3 /h] 141.7 104.3 200.8 132.7 Maximum pressure [mm H 2 O] 1.22 2.3 0.95 1.94 Actual input power [W] 1.3 1.0 2.2 1.4 Maximum rated input current [A] 0.2 0.2 0.3 0.2 Nominal input voltage [V] 12V 12V 12V 12V Minimum startup voltage [V] 4V 6V 4V 7V Low (0-20%) PWM speed 400 RPM 400 RPM Low PWM Static pressure 0.45 mm H2O 0.54 mm H2O Low PWM Air flow 15.4 CFM 26.2 m3/h 24.0 CFM 40.8 m3/h Low PWM Noise level < 10 dB (A) < 10 dB (A) Low speed adapter speed 1100 RPM 850 RPM Low speed adapter Static pressure 0.89 mm H2O 0.59 mm H2O Low speed adapter Air flow 65.8 CFM 111.8 m3/h 78.5 CFM 133.4 m3/h Low speed adapter Noise level 19.0 dB (A) 18.3 dB (A) MTBF [hours] 150,000 150,000 150,000 150,000 Unit weight [g] 169 179 202 210 Package weight [g] 215 225 260 270 Cable length [mm] 500 500 500 500 Cable type Braided all-black ribbon wire Braided all-black ribbon wire Braided all-black ribbon wire Braided all-black ribbon wire Packaging dimensions [mm] ( Including hanging tab) 180*122*30 180*122*30 200*142*30 200*142*30 Packaging dimensions [mm] (Excluding hanging tab ) 147*122*30 147*122*30 167*142*30 167*142*30 Package contents Venturi Series fanScrew pack with 4 metal screws[HF models] Low speed adapter[HP models] 1->2 PWM signal splitter cable[140 mm models] 4 additional rubber corners, with 105mm hole pattern
