Arctic F12 PWM PST

Case Fan F12 with PWM PST, 4-pin, 120mm, black.  Features:  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. Perfect case fan regulation with PWM. The PWM function allows the motherboard to run the fan precisely at its necessary speed. This guarantees the required cooling and minimizes the noise level. Innovative design enables quiet and efficient ventilation. The innovative design of the fan blades improves the air flow and facilitates a highly efficient ventilation. The impeller was designed with a focus on minimizing the noise level yet delivering the desired airflow and pressure. 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. Long service life. The Fluid Dynamic Bearing comes with an oil capsule that avoids lubricant leakage. Thus this bearing is as quiet as a sleeve bearing but comes with a significantly higher 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, these fans are covered by a 6-year manufacturer's warranty. Two way installation. Push warm air out of the case. Pull cool air into your case.  Specifications:  Speed: 230-1350 rpm.
