ARCTIC F9 PWM PST CO Case Fan, 4-pin, 92mm, Black

Case Fan F9 with PWM PST for continuous operation, 4-pin, 92mm, black.
Features: Designed for continuous operation. The premium quality of the dual ball bearing allows 24/7 continuous operation without compromising performance. Contamination and high temperatures affect this bearing much less than ordinary sleeve or ball bearings. Therefore, the dual ball bearing is the perfect choice if you want to ensure continuous operation at maximum speed. Please note that ball bearings have a physically higher bearing noise compared to conventional sleeve bearings. 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. 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.
