40mm Fan Damping Gasket

I place these in between a fan and whatever surface it is mounted to. The small washers (not shown in photo) are optional, but help the fan lightly "float" inbetween the screw head and the mount surface. I use just enough tightness so the fan holds in place. I tend to sandwich the fan between an intake duct and a fan duct, so two of the squares are needed for my designs. One of these between a finger guard and fan would help too.

The material here is 1/16" thick or ~2mm thick adhesive back
