Alphacool's Core 120mm is a quiet and efficient fan with a wide control range up to 3000 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!
