Product details

The fan blades are what make a fan. For this reason, the fan blades of the Silent Wings Pro 4 140mm PWM have been optimally developed from the ground up.
The blade arrangement enables unsurpassed performance in all kinds of applications. Be it in a case, on radiators or heat sinks. Silent Wings Pro 4 140mm PWM provides exceptional air pressure, significantly increasing system performance. The reduced distance between the fan blades and the frame enables an exceptionally high air pressure. As a result, the Silent Wings Pro 4 140mm PWM allows the user to run even the most demanding applications.
