80mm Computer Fan Filter Grills with Screws, Aluminum Frame Ultra Fine Stainelss Steel Mesh - 4 Pack (Black)

If you're looking for grills for your fans, you'll love these high quality grills. They have a fine screen, but are built to be durable. I'll use these again for my next project that requires cooling.

I'm not actually using these for a PC case (the most common use-case), though I do have similar but larger grills for PC use. I bought these to use in a custom 3D-printed case for a Meanwell Power Supply which I'm using for LED lighting. The PSU has a very open frame (for heat ventilation), and I wanted to keep dust out of it (one of these is sitting in a storage cupboard, and the other on top of kitchen cabinets) but without blocking the heat dissipation. I thus designed and 3D-printed (using HTPET+ filament from Fusion Filaments) a case for the PSU that still allowed ventilation around the PSU chassis, while using these filters to stop dust accumulating in the PSU. They've worked great for that purpose, and I'm sure would work just as well for use with suitably size fans in a PC case or other similar application.

Nice metal filter, better than paper. Easy to clean.

A good quality wire mesh screen for fans. However, the mesh size is not small enough to really protect the fan from dust and dirt. For example, I poured some granulated sugar over one and most of the sugar went straight thru. For hair, dust bunnies, etc it will work fine; just expect to see some dust buildup inside your equipment over time. The other thing that was a bit confusing at first is you install with the screw hole concave surface facing against the cabinet - not outside which would seem reasonable to have the screws be flush. If mounted with concave holes out then the edges of the filter have a 1/16" or so rise off the cabinet surface - defeating the screen function entirely. So make sure you have the concave hole openings towards the cabinet (filter fits flush); the screw heads will be sticking a bit. The accordian aspect of the mesh gives the filter some strength to protect things from poking in; however I found adding a regular finger guard on top gives me a better state of mind that something won't poke a hole into the filter and let the screw heads be more flush with the guard. I'm reasonably pleased with the filter as the larer openings in the mesh won't have a serious impact on airflow; but then the filtering capability is not that great for ordinary dust/dirt. A compromise for pretty much any of these muffin fan filters. The other alternative would be using the filter backwards and installing a anti-vibration gasket. I considered this but decided I didn't want to buy yet another product. However the gasket would seal the filter as well as allow using the concave holes with the tapered head screws - just a thought

My home network equipment is in the garage and sometimes malfunctions due to heat. Using 12volt 80mm case fans, a 12volt barrel style Y-adapter and barrel to screw terminal ends my modem, router and Vonage hardware now run cooler without malfunctions.

Perfect to keep my sped kids away from sticking their fingernails into my exposed aio radiator.

These dust shrouds for 120mm PC case fans work beautifully, they have little to no noticeable performance drawbacks in terms of air flow, but are fine enough mesh to catch most hair and dust. They don’t rub against my PCs case fans and they also don’t make the front panel less lit up from the RGB fans, they seem to perform perfectly and are easily accessible, as well as easy to install. Great product!!

Very pleased with this purchase! These fan filter grills are perfect with my cooling platform. Exactly what I needed to keep the dust away from the fan's interior.
