Semi-passive case fan P14 PWM PST with digital A-RGB, 4-pin, 140mm, black.Features:Addressable RGB for full colour control. The P14 PWM PST A-RGB has 12 digital A-RGB LEDs in the center fan wheel. These can be controlled independently of each other and are compatible with the common A-RGB standards of leading motherboard manufacturers. The fan can thus be fully illuminated directly the A-RGB mainboard connector or via an external controller and synchronised with the illumination of other hardware.PWM PST technology allows multiple fans to be connected (up to 5 recommended), synchronizing their operating speed based on the actual computer cooling demands. In this way, the entire cooling system operates more efficiently and quietly, and the total energy consumption is lower than when each fan / cooler is connected separately.0dB mode — zero rpm. The speed of the fan can be throttled down to a standstill via PWM. This allows silent operation in IDLE and at the same time guarantees maximum performance when required.Optimised for static pressure.During the development of the new P14 PWM PST A-RGB, special emphasis was placed on a focused airstream and thus a high static pressure. The fan guarantees extremely efficient cooling, even with increased air resistance. Therefore, the P14 PWM PST A-RGB is particularly suitable for use on heatsinks and radiators.Maximum quietness, minimum vibration. Even at low speeds the operating sound of the new ARCTIC motor is barely noticeable. Due to a sinus-magnetizing the new motor only creates about 5% of the vibration from commutation of a regular DC-motor without filter.High quality bearing. Thanks to an alloy/lubricant combination developed in Germany, friction within the bearing is reduced and greater efficiency is achieved. As a result, there is less heat development as well as less bearing noise, which means you can enjoy a longer service life from your fan.200 to 1900 rpm controlled via PWM PST. With a wide speed range and the innovative PWM Sharing Technology (PST), the fan speed of the P14 PWM PST A-RGB can be controlled synchronously with all other fans. This reduces noise to a minimum while guaranteeing maximum cooling performance.Long service life. Excellent results of long-term testing, even in particularly unfavorable conditions, ensure that these products are characterized not only by quality, but also by durability. Therefore, P14 PWM PST A-RGB fans are covered by a 6-year manufacturer's warranty.Specifications:Fan speed: 200-1900 RPM.Airflow: 68.9 CFM / 117.06 m³/h.Noise level: 0.3 Sone.Fan bearing: fluid dynamic bearing.Current / voltage: 0.17 A / 12 V DC.Starting voltage: 5 V.Connector: 4-Pin-Connector + 4-Pin-Socket.LED: 12x A-RGB.A-RGB connection: 3-Pin 5V-DI-Gnd.A-RGB current / voltage: 0.4A / 5V.Size: 140x140x27 mm.Color: black body, optional lighting.Weight: 225 g.Warranty: 6 years.
