Alphacool Shroud & Decoupler 120mm (7mm πάχος) με 4x M3x37mm βίδες (24830)

7mm EPDM rubber shroud decouples 120mm fans from radiators, cutting vibration noise by up to 30% while boosting static pressure through reduced air leakage.

Overview

The Alphacool Shroud & Decoupler 120mm is a precision-engineered accessory for PC water cooling enthusiasts. Made from dense EPDM rubber, it sits between a 120mm fan and radiator or case panel, absorbing motor vibrations and preventing resonance. The 7mm thickness creates an optimal gap that straightens airflow, reducing turbulence and improving cooling efficiency. Four included M3x37mm steel screws provide secure mounting through the shroud into standard fan holes (105mm x 105mm spacing). Compatible with all 120mm fans and radiators, this shroud is an essential upgrade for silent, high-performance systems.
