Radiator Gaskets and Shrouds
Two different jobs that mount in the same place. A gasket is a thin foam sheet between the radiator and the case panel, which stops the two metal surfaces buzzing against each other and closes the air gap that lets intake air escape around the rad instead of through it. A shroud is a spacer between fan and rad, giving the air room to spread past the motor hub before it hits the fins.
Darkside foam gaskets come cut to radiator length: 120mm, 140mm, 280mm and 360mm at 1mm thickness, and a 360mm at 3mm where the panel is not flat.
Alphacool and Phobya supply the 7mm shroud and decoupling parts in 120mm and 140mm. The Alphacool versions include 4x M3 x 37mm screws in the box.
Adding a shroud adds to the screw length you need. Longer M3 and 6-32 hardware is in screws.
