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.
