Where it goes
Alphacool's Core 120mm, as its maker puts it, is a quiet and efficient fan with a wide control range. Controlled via a PWM signal, it is not only suitable as a fan on CPU coolers or radiators. Thanks to what Alphacool calls excellent performance values (throughput & static pressure), it can also be used as a case fan. The hydraulically mounted fan axis runs smoothly, which Alphacool says enables a long service life and quiet operation. If you are looking for a powerful fan in a version without lighting, Alphacool says you will find it in this one.
Connections
The cable on the fan is 40 cm long. That allows it to be connected directly to the mainboard (motherboard) or to a special, dedicated controller, without using additional adapter cables or extensions.
Control range
Speed is set through the 4-pin PWM connection. At maximum speed the fan allows an air flow of 72.63 CFM, paired with what Alphacool calls a high static pressure of 2.42 mm/H2O. Alphacool says this makes the fan perfect for mounting on radiators of a water cooling system or for ventilating a case.
Power and service life
The nominal voltage is DC 12V, and the starting voltage is 7V. Rated capacity, the power the fan draws, is 3.6 W, and rated current is 0.3 A. The material is plastic, and the bearing type is hydraulic bearings. Alphacool gives a life expectancy of 50000 hours at 25 degrees Celsius, and an operating temperature of -10 to +55 degrees centigrade. The other characteristics it lists are a tachometer output, auto start, soft start and waterproof level IP22.
What it needs
Each fan takes one free 4-pin PWM header. Alphacool's scope of delivery lists one fan and nothing else, so plan for fan screws if your radiator or case did not come with them.
