The ARCTIC F12 PWM CO PST cools a system 24 hours a day, 7 days a week, at low noise levels. "CO" represents continuous operation and implies that the fan is provided for systems that are in constant use, such. B. server. A double ball bearing reduces friction and thus wear. The F12 PWM CO PST is much less sensitive to dust and thanks to the patented suspension it is not only very quiet in operation, but in addition also very durable. In addition, the built PST (PWM sharing technology), which forwards the PWM signal to the CPU to up to four other components of the ventilation system. So you can operate the entire housing ventilation in lockstep. In periods with little load equally silent, but if necessary all at once quickly and thus cool extremely effective. The F12 PWM CO PST offers excellent performance at optimum operating temperatures at all times.
