Alphacool's Core 120mm is a quiet and efficient fan with a wide control range up to 4000 rpm. The fan, which can be controlled via a PWM signal, is not only suitable as a fan on CPU coolers or radiators. Thanks to its excellent performance values ​​(throughput & static pressure), it can also be used as a case fan. The double-bearing fan axis is smooth-running and enables a long service life and quiet operation. If you are looking for a powerful fan without aRGB lighting, you will find it in Alpacool's Core 120mm version! 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 mainboard or a special controller without using additional adapter cables or extensions. Control range The fan can be controlled from 0 to 4000 rpm via the 4-pin PWM connection. At maximum speed it allows an airflow of 119.8 CFM paired 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.
