ARCTIC F12 PWM CO 120mm Case Fan

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, theF PWM COseries 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.
