NOTE: This shroud does not come with LED in the package. If you need LED for this shroud, you can purchase it separately. Available colors are RED, BLUE and GREEN.
The TFC Xtender 120mm Radiator Shroud is designed to increase the air flow performance of a fan. The Feser XTENDERs tunnel principle holds the air during its rotation inside and improves the air flow through a radiator. The air can not escape and is forced towards the radiator. Directly behind the middle of the impeller is no airflow, also called as the dead spot. Air turbulence is needed to pick up the heat from the heat source. By using the XTENDER SHROUD the air turbulence is increased within this tunnel volume and fills in the dead spot, thus you gain more cooling performance for your radiator or cooling device.
