50mm 5cm Fan Guard Grill PC Case Fan Protector - Metal Cooling

The 50mm fan guard is a metal wire grill that mounts directly over a 50 × 50 mm PC case or 3D printer fan, protecting blades from contact while keeping airflow open and unrestricted.

This 50mm fan guard slots over standard 50 × 50 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.

Key Features of the 50mm Fan Guard

• Fits standard 50 × 50 mm fans — compatible with PC cases, 3D printers, and industrial enclosures
• Guard wire diameter: 41mm — sized to protect the blade area without blocking mounting holes
• Open wire mesh construction — less restrictive than solid stamped grilles
• Metal build, silver-tone finish — durable and rust-resistant
• Lightweight at 9g — adds no meaningful load to case panels or 3D printer frames
• Protects fan blades and prevents fingers or cables from contacting spinning blades
• Drop-in replacement for restrictive stock case fan grilles

Use Cases
