Core 120mm fan PWM 4000rpm (120x120x25mm) 24845 Features: Connections The fan is controlled via a 4-pin PWM connector. The cable is 40cm long. This allows the fan to be connected directly to the motherboard or a dedicated controller without the use of additional adapter cables or extensions. Control range The fan can be controlled from 0 to 4000 rpm via the 4-pin PWM connector. At maximum speed, it allows an airflow of 119.8 CFM combined with a high static pressure of 12.67 mm/H2O. This makes the fan perfect for mounting on radiators of a water cooling system or for ventilating a case.
