The fan blades are what make a fan. For this reason, the fan blades of the Silent Wings Pro 4 120mm PWM have been completely redesigned from the ground up. The new blade arrangement allows for unmatched performance in all possible applications, whether in a case, on radiators, or heatsinks. The Silent Wings Pro 4 120mm 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 120mm PWM allows users to handle even the most demanding applications.
