Product details

The fan blades are what make a fan effective. For this reason, the blades of the Silent Wings Pro 4 140mm PWM have been optimally designed from the ground up. The arrangement of the blades allows for unparalleled performance in all possible applications, whether in a case, on radiators, or heatsinks. The Silent Wings Pro 4 140mm PWM provides exceptional air pressure, significantly enhancing system performance. The reduced distance between the fan blades and the frame enables an extraordinarily high air pressure. As a result, the Silent Wings Pro 4 140mm PWM allows users to run even the most demanding applications.
