Product Descriptions Dedicated to operate 24 hours a day, 7 days per week, the F PWM CO series case fans cool your computer system quietly. The fan forwards the PWM signal from the CPU to the whole case ventilation system. Employing a Japanese dual ball bearing, the fan operates with reduced friction and hence its lifespan is substantially extended. The series offers you with superb performance while maintaining your computer systems under optimal temperature at all times.

Continuous Operation "CO" stands for Continuous Operation and makes the case fans suitable for PCs with non-stop operation like servers. This feature is brought by the Japanese dual ball bearing used in the fans, which reduces rotational friction, meaning it is less sensitive to dust and high temperature and hence is up to 5 times more durable than generic or modified bearings.

Constantly Silent Thanks to the dual ball bearing and the patented fan holder design, the F PWM CO series is not only quiet, but also long-lasting.

Quick and Easy Setup Via a single PWM signal, the CPU fan is controlled by the mainboard to maintain the ideal temperature of the CPU. The patented PST (PWM Sharing Technology) forwards the PWM signal to all other fans within the system so that all fans are spinning at the same speed. Such mechanism ensures silent operation when it is idle, but also gives sufficient performance when the demand comes.
