GELID Solutions Rubber / Silicone Computer Case Fan Vibration Dampening Soft Mounting Screws / Mounts
Rubber fan mounts help dampen vibrations created by case fans before they can travel to the steel walls of the case. Though soft, the rubber will not break or tear during installation and will last years, even at high temperatures. Suitable for most open case fan sizes and cases with holes up between 4 and 5.5 millimeters. They're easy to install and don't require screwdrivers.
