Details
The Alphacool Core 140mm Fan PWM 2000rpm is a 140 x 140 x 25 mm fan with a 4-pin PWM connector and a control range from 0 to 2000 rpm. It has no aRGB lighting and is suitable for radiators, CPU coolers and as a case fan.

Where it is used
Alphacool calls its Core 140mm a quiet and efficient fan with a wide control range. Since it can be controlled via a PWM signal, the fan is not only one for 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 without aRGB lighting (illumination), Alphacool says you will find it in this version of the Core 140mm. The next step up in the same range is the Core 140mm Fan PWM 2500rpm.
Connections
A 4-pin PWM connector controls the fan, and the cable is 40 cm long. This allows the fan to be connected directly to the mainboard (motherboard) or to a special, dedicated controller. That works without using additional adapter cables or extensions.
Control range
Via the 4-pin PWM connection the speed can be set anywhere from 0 to 2000 rpm. At maximum speed Alphacool gives an airflow of 103.03 CFM, paired with what it calls a high static pressure of 2.81 mm/H2O. Alphacool says this makes the fan perfect for mounting on radiators of a water cooling system or for ventilating a case.
