The 80mm fan guard is a metal wire grill that mounts directly over a 80 × 80 mm PC case or 3D printer fan, protecting blades from contact while keeping airflow open and unrestricted. This 80mm fan guard slots over standard 80 × 80 mm fans and replaces overly restrictive solid-stamped stock grilles. The open wire mesh design lets air flow freely compared to punched-plate covers, making it ideal for case mods, blowhole modifications, and any build where finger safety and clean airflow both matter. In addition, the silver-tone metal construction is durable and matches most standard case interiors.
