Shroud & decoupling 140mm (7mm thick), installation frame

The Alphacool Fan Shroud optimizes the airflow between the fan and the radiator’s cooling fins to increase cooling performance. In addition, it decouples the fans, which leads to a significant reduction in noise. When mounting the fan directly on the radiator, a dead spot is created below the fan hub. Even at the corners of the radiator that are not directly covered by the fan blades, there is only a small amount of air movement through the cooling fins. By installing the fan shroud, the distance between the fan blades and the radiator is increased. This allows an air cushion to build up in this intermediate area. The dead area below the fan hub is eliminated and the corners of the radiator are better supplied with cooling air. The cooling performance can be noticeably increased, especially with silent fans at low speeds. The soft fan shrouds largely decouple the fans from the radiator frame. This means that hardly any vibrations are transmitted and the volume is reduced. The greater distance between the fans and the cooling fins also ensures less direct air turbulence on the fan edges and radiator fins. This also contributes to a reduced background noise.
