40mm Fan Guards Set of 5

This set provides five matte-black fan grills designed specifically for 40mm fans. Each guard uses round struts and an offset layout to protect the blades while keeping airflow smooth and noise low. The package includes twenty screws and twenty tool-free push-pin mounts for flexible installation. Buyers receive a complete kit to shield multiple fans in one purchase.

Who Benefits and Who Does Not

These grills suit builders who want finger-safe protection for 40mm fans in PCs, 3D printers or small ventilation units. The push-pin system allows fitting without tools even when fans are already mounted. Users needing guards for larger fan sizes or a different colour finish will not find a match here. The kit only covers the 40mm form factor in black.

Offset Push-Pin Mounting System

The included push-pin mounts add a 5mm stand-off that reduces influx turbulence and improves acoustic performance. This tool-free design lets you secure the grills quickly without removing the fan from the chassis. It is the single feature that determines whether the kit fits your workflow and noise targets.

Questions about this item

Should I get the Sx5 set or the Sx2 set?

The Sx5 set contains five grills with twenty screws and twenty push-pin mounts, while the Sx2 set contains two grills with eight screws and eight push-pin mounts. Choose Sx5 if you need to cover five 40mm fans.

How much does the push-pin offset change airflow and noise?

The push-pin mounts add a 5mm offset that reduces influx turbulence, giving smoother airflow and lower noise compared with direct screw mounting.

What mounting standard do these grills use?

They fit standard 40mm fan frames and include both traditional screws and a tool-free push-pin system for the same hole pattern.
