Alphacool 140mm Fan Grill, black, model 10338

The Alphacool 140mm Fan Grill, model 10338, is a black protective cover made for installation on standard 140 mm PC fans. Engineered to provide a solid barrier between moving fan blades and external objects, this fan grill helps prevent accidental contact with fingers, cables or other components while preserving unrestricted airflow. It is intended for use in computer cases, on radiators and on fan mounts where a slim, durable grill is required to improve safety and cable routing without changing fan performance.

Advantages

The grill offers a robust physical barrier that reduces the risk of damage from accidental contact while keeping the blade area accessible to cooling air. Its black finish integrates visually with most case interiors and fan frames. The design minimizes airflow obstruction, so cooling efficiency of the attached 140 mm fan is largely retained. The product is straightforward to mount and requires no modification of the fan itself.

Suitable for

• Protecting 140 mm case fans in desktop PCs
• Use on radiators where a protective cover is needed
• Fan mounts in custom or compact builds to prevent cable snagging
• Environments where safety near spinning blades is required (workstations, public displays)

When it may not be suitable

This grill is designed for standard 140 mm fans and may not fit non-standard or proprietary fan housings. If you require integrated dust filtration, this product does not provide filtering functions; an additional dust filter would be needed. For applications where absolute maximum airflow is critical, any additional grill surface will introduce a small amount of airflow resistance.

Key specifications

• Size compatibility: 140 mm fan diameter
• Color: black
• Material: rigid protective construction (metal or reinforced polymer as typical for fan grills)
• Mounting: designed for standard 140 mm screw holes and fan mounts
• Thickness/profile: low-profile design to avoid interference with fan or radiator surfaces

How to use

Position the Alphacool 140mm Fan Grill over the fan so that the screw holes align with the fan’s mounting points. Use the standard fan screws to secure the grill to the fan frame or chassis, taking care not to over-tighten screws to avoid deforming the fan frame. Ensure that cables are routed clear of the grill before final fastening. For radiator installations, fit the grill between the radiator and the case or directly to the fan if space allows, verifying there is adequate clearance for both the fan and the grill.

What to consider before purchase

• Confirm your fan is a standard 140 mm model and has compatible mounting hole spacing
• Decide whether you need dust filtration in addition to blade protection
• Check available clearance around radiators or tight mounts to ensure the grill will not interfere with adjacent components

Usage recommendations

Install the grill with standard fan screws and check cable routing to prevent contact with the blades. For radiator-mounted fans, verify that the grill does not compress any rubber pads or obstruct airflow paths; perform a visual inspection after installation to ensure secure mounting and free-spinning blades.
