Best Custom Fan Grilles and Screens for PC Cases in 2026

1. MoKo 140mm Magnetic Dust Filter 4 Pack

I’ve used these MoKo magnetic filters on several builds, and they’re honestly one of the most convenient options for everyday PC maintenance. The magnetic frame design means you can pop them off in seconds when it’s time to clean out the dust bunnies, then snap them right back on. No screwdriver required, no crawling behind your desk to access mounting screws.

The PVC mesh is surprisingly effective at catching dust while letting air flow through. After three months of use on a gaming rig that sits on a carpeted floor, I found a noticeable layer of dust trapped on the filter surface. The mesh itself showed minimal airflow restriction compared to running without any filter at all. Temperatures increased by maybe 1-2 degrees Celsius, which is negligible for most builds.

The 4-pack configuration is perfect if you have multiple intake fans or want spares. I ended up using two on front intake fans, one on a bottom PSU intake, and kept the fourth as a backup. At this price point, having extras makes sense. The mesh is flexible enough that you could technically cut it to fit slightly non-standard openings if needed, though the magnetic frame works best with standard 140mm fan mounts.

One thing to watch out for: the magnets can lose their grip over time, especially if you’re frequently removing and reattaching them. I’ve had one fall off after about a year of regular cleaning cycles. The mesh itself can arrive with some creases from packaging, but these don’t affect functionality. For the price, these are hard to beat for pure practicality.

For whom its good

This is perfect for PC builders who prioritize easy maintenance and dust control over aesthetics. If you have your case on the floor where dust accumulation is a real concern, these filters will save you significant cleaning time. The magnetic attachment makes them ideal for anyone who cleans their PC regularly.

For whom its bad

If you’re building a showcase PC with a glass side panel and want everything to look pristine and coordinated, these basic black mesh filters won’t win any design awards. They’re purely functional. Also, if you have a case without steel mounting surfaces, the magnets won’t have anything to grip.

2. ThreeBulls 12 Pack 120mm PVC Dust Filters

Twelve filters for the price of a single premium grill. That’s the ThreeBulls proposition, and honestly, it’s compelling if you’re outfitting multiple systems or just want lifetime supply of dust protection. I’ve distributed these across three different builds in my home office, and still had leftovers for future projects.

The PVC mesh is fine enough to catch most dust particles while remaining surprisingly permeable to airflow. I ran some informal temperature comparisons with and without these filters installed, and the difference was barely measurable, maybe 1 degree Celsius at most. The mesh is flexible enough that you can trim it with scissors if you need a slightly smaller size, though the pre-punched screw holes assume standard 120mm mounting.

Installation is straightforward with the pre-punched mounting holes. The material has some rigidity to it, which actually helps it hold its shape over the fan, but this also means you can’t really bend it around curves. I’ve found that overtightening the screws can crack the material, so finger-tight is plenty. Once installed, they stay put and do their job quietly.

The main trade-off here is aesthetics. These are purely functional black mesh filters with no custom design elements. They won’t make your build look more impressive through a side panel window. But for builds where the intake fans face a wall or sit inside a desk cabinet, nobody will see them anyway. The value proposition here is unmatched.

For whom its good

Anyone building multiple systems, maintaining a home server, or just wanting practical dust protection without spending much money will love these. The 12-pack means you can outfit an entire case with intake and exhaust filtration and still have spares. Perfect for practical builders who don’t need their filters to be visible design elements.

For whom its bad

Showcase builders with glass panels and RGB lighting won’t find these appealing. They’re purely utilitarian. Also, if you need magnetic mounting for easy removal, these require screw installation, which is less convenient for frequent cleaning access.

3. SilverStone FF81 80mm Honeycomb Fan Filter

Not every build uses 120mm or 140mm fans. For compact cases, SFF builds, and older systems, 80mm fans are still relevant, and finding quality accessories for them is surprisingly difficult. The SilverStone FF81 fills that gap with a honeycomb design that’s been around for over a decade because it works.

The honeycomb pattern here serves two purposes: it looks clean and professional, and it focuses airflow through the hexagonal openings. I’ve used these on several small form factor builds where every millimeter of space matters. The integrated filter behind the honeycomb grille catches dust effectively without significantly impeding the already limited airflow from smaller fans.

Build quality is solid for the price point. These aren’t going to win awards for premium materials, but they’re sturdy enough to survive multiple installation cycles. The included mounting screws work for most standard applications, though I’ve encountered some thicker case panels where longer screws were needed. The filter element is easy to remove and clean, which is essential for smaller builds where dust accumulation happens faster.

For anyone running an older case or a compact build with 80mm fan mounts, this is probably your best option. SilverStone has been making these for years, and the consistent quality shows. It’s a practical, no-nonsense solution for a size category that most manufacturers have moved away from.

For whom its good

Small form factor builders, anyone with older cases that use 80mm fans, and compact NAS or server builds will find this essential. The honeycomb design provides better airflow than solid grills while still offering protection and dust filtration.

For whom its bad

If you’re looking for custom aesthetic designs or premium materials, this basic honeycomb filter won’t satisfy. It’s purely functional. Also, the 80mm size limits compatibility to specific older or compact cases.

4. AC Infinity 120mm CNC Aluminum Ventilation Grille

This is what happens when someone actually cares about build quality. The AC Infinity ventilation grille is CNC machined from aluminum with a brushed black finish that looks premium in any build. I’ve installed these in client builds where appearance mattered as much as function, and they never disappoint.

The frame is substantial, with clean machining marks that speak to quality manufacturing. The honeycomb insert provides the classic airflow-focused pattern while looking more refined than stamped metal alternatives. This isn’t just a dust cover; it’s a design element that elevates the entire look of your case’s ventilation area.

What really sets this apart is the versatility. The included hardware kit covers virtually every mounting scenario: wood screws for cabinet installations, machine screws with nuts for metal panels, and fan mounting hardware. I’ve used these for AV cabinet ventilation projects as often as PC builds. The ability to mount a 120mm fan directly to the grille makes it a complete solution for custom cooling projects.

The airflow characteristics are excellent thanks to the honeycomb pattern. There’s minimal resistance compared to more restrictive designs. I’ve measured temperature differences of less than 1 degree Celsius compared to running fans without any grille, which is impressive for any protective cover. The metal construction also means there’s no concern about material degradation over time like you might see with some plastics.

For whom its good

Premium builders, anyone creating showcase PCs with visible fan areas, and people doing custom AV cabinet ventilation will get the most value here. The professional appearance and versatile mounting options make it worth the investment for builds where quality matters.

For whom its bad

If you’re on a tight budget or just need basic dust protection for a case that sits under a desk, this premium option is overkill. The aluminum construction also means it’s not magnetic, so you’ll need to use the included mounting hardware.

5. Inspired Laser Design Flame Acrylic Fan Grill

This is where function meets artistic expression. The Inspired Laser Design Flame grill takes a3mm gloss black acrylic and transforms it into something that actually makes your build look unique. I’ve used this on a fire-themed gaming build, and it became a genuine conversation piece.

The laser cutting is precise, with clean edges that don’t need any finishing work. The 3mm thickness gives it substantial feel, not the flimsy quality you might expect from decorative grills. The gloss black finish catches RGB lighting beautifully, reflecting colors and adding depth to your lighting scheme that plain mesh simply cannot match.

Let’s talk about the elephant in the room: airflow. This is a more restrictive design than open mesh or honeycomb patterns. The flame cutouts are artistic, but they do block more air. In my testing, I saw temperature increases of 2-3 degrees Celsius compared to running without any grill. For most builds with adequate cooling, this is manageable, but for thermal-sensitive configurations, it’s worth considering.

Installation requires some planning. No mounting hardware is included, so you’ll need your own screws. The acrylic can crack if overtightened, so I recommend using rubber washers and going finger-tight only. Some builders countersink the holes for a flush look, which does require additional work but creates a cleaner finished appearance.

For whom its good

Showcase builders, anyone with a fire or heat-themed build, and RGB enthusiasts who want their lighting to interact with interesting surfaces will love this. The unique design makes it perfect for builds where standing out matters more than maximum airflow.

For whom its bad

Anyone running a thermal-sensitive build, overclocking extensively, or using this on a CPU cooler fan should look elsewhere. The restricted airflow makes it unsuitable for critical cooling paths. Also, if you want a complete kit with hardware included, you’ll need to source screws separately.

6. Inspired Laser Design Flying Dragon Acrylic Grill

The Flying Dragon design has developed something of a cult following in the PC building community, and after using one, I understand why. The intricate dragon silhouette creates a striking visual that’s particularly impressive when backlit with RGB fans. This isn’t just a fan cover; it’s art.

The same 3mm gloss black acrylic as the flame design, but the dragon pattern creates a completely different aesthetic. The mirror-like surface reflects RGB lighting in a way that makes your colors pop and dance. I’ve seen this installed in builds at LAN parties, and people consistently stop to look at it. It’s one of those details that transforms a good build into a memorable one.

Quality-wise, Inspired Laser Design makes these in the USA, and the manufacturing consistency shows. Every cut is clean, every edge is finished properly. The design is intricate enough to look impressive while remaining structurally sound. After a year of use, mine still looks as good as the day I installed it, with no warping or degradation.

The airflow situation is similar to the flame design. This is not a high-airflow option. The solid areas of the dragon design block more air than they let through. I measured roughly 3-4 degree Celsius increases in case temperature compared to no grill. For builds with robust cooling that aren’t pushing thermal limits, this is acceptable. For anything running hot, mount this somewhere other than your primary intake or exhaust.

For whom its good

RGB-focused builders, anyone with a gaming-themed build, and showcase PC creators will get maximum enjoyment from this. The dragon design resonates particularly well with gaming aesthetics. Perfect for builds where visual impact matters more than optimizing every degree of temperature.

For whom its bad

Performance-focused builders pushing thermal limits should avoid this on primary airflow paths. The restrictive design will impact temperatures. Also, if you’re rough with installations or tend to overtighten screws, the acrylic construction may not survive your building style.

7. MoKo DIY 400x300mm Magnetic Dust Filter

Sometimes standard sizes just don’t fit your needs. That’s where the MoKo DIY filter sheets shine. These 400x300mm sheets with included magnetic strips let you create custom-sized filters for virtually any application. I’ve used these for everything from non-standard case vents to speaker cabinet protection.

The concept is simple but effective: large mesh sheets with separate magnetic strips you attach around the edges. Cut the mesh to your desired size, apply the magnetic strips, and you have a custom filter. The 1mm hole size catches most dust and pet hair while maintaining reasonable airflow. For pet owners, this is genuinely useful, keeping fur out of your expensive components.

The versatility extends beyond PC cases. I’ve seen these used on gaming consoles, AV receivers, and even 3D printer enclosures. The magnetic attachment means no drilling or permanent modification, which is perfect for expensive equipment you don’t want to alter. When it’s time to clean, just peel it off and rinse under water.

The main limitation is the included magnetic strip quantity. For larger cutouts, you might need to supplement with additional magnetic tape. The included strips work well on steel cases but obviously won’t attach to aluminum or plastic panels without some creative solutions like adhesive-backed metal strips.

For whom its good

Pet owners, anyone with non-standard case ventilation needs, and people who want to filter multiple devices with one product will find this incredibly useful. The DIY aspect means you’re not limited to standard fan sizes.

For whom its bad

If you need very fine dust filtration for environments with lots of fine particulates, the 1mm holes may be too large. Also, if you want a polished, finished look for a showcase build, the cut-to-size DIY appearance might not meet aesthetic standards.

8. Inspired Laser Design 200mm Honeycomb Acrylic Grill

Finding accessories for 200mm fans is genuinely difficult. Most manufacturers focus on 120mm and 140mm, leaving large fan owners with limited options. The Inspired Laser Design 200mm honeycomb fills that gap with the same quality acrylic construction as their smaller designs.

The honeycomb pattern here makes more sense than their solid artistic designs because large fans move significant air volume. Restricting a 200mm fan’s airflow would have noticeable thermal impact. The honeycomb maintains most of the airflow while providing finger protection and a clean finished look. I’ve used this on a Fractal Design case with a 200mm front intake, and it completed the aesthetic while keeping temperatures virtually unchanged.

The 3mm gloss black acrylic matches their other products in quality. Laser cutting is precise, and the finish catches RGB lighting effectively. The honeycomb pattern looks professional rather than decorative, which suits builds where you want a clean, technical appearance rather than gaming-themed artwork.

Compatibility is worth checking carefully. Some 200mm fans have slightly different mounting patterns or dimensions, and this grill may be marginally larger than your fan. I’ve encountered cases where the grill overlapped slightly with case features. Also, the honeycomb holes are large enough that small fingers could potentially reach spinning blades, so this isn’t a child-safety solution.

For whom its good

Anyone with a case using 200mm fans, Fractal Design or Cooler Master case owners, and builders wanting to protect large intake fans will find this essential. The honeycomb pattern maintains the airflow benefits of large fans while adding protection.

For whom its bad

If child finger safety is a concern, the large honeycomb openings won’t provide adequate protection. Also, verify your 200mm fan dimensions carefully, as compatibility can vary between case manufacturers.

9. Noctua NA-FG1-12 Sx2 Premium Fan Grills

Noctua doesn’t make compromises, and their fan grills reflect that philosophy. These premium matte-black guards come in a set of two with both screw mounting and tool-free push-pin options. For small form factor builds or any application where cable management and clean aesthetics matter, these are worth every penny.

The design philosophy here focuses on airflow optimization. Round struts instead of flat bars reduce noise and turbulence. The 5mm offset created by the push-pin mounting gives air space to spread before hitting the guard, further reducing turbulence. I’ve measured noise reductions of 1-2 dB compared to cheaper wire guards, which matters more in quiet builds than you might expect.

Build quality is exactly what you’d expect from Noctua: flawless. The matte black finish is consistent, the wire forming is precise, and the mounting hardware works perfectly. The push-pins are particularly well-designed, holding securely while being genuinely tool-free for installation and removal. For SFF builds where you might need to access cables behind fans, this matters enormously.

The airflow characteristics are as close to unrestricted as any grill I’ve tested. Temperature differences compared to running bare fans are negligible. For performance-focused builds where every degree matters, these won’t hold you back. They’re particularly excellent for CPU cooler fans where airflow restriction would have immediate thermal consequences.

For whom its good

Small form factor builders, quiet PC enthusiasts, and anyone who values build quality over saving a few dollars will love these. The push-pin mounting makes them ideal for tight builds where screw access is limited. Also perfect for protecting CPU cooler fans without restricting their critical airflow.

For whom its bad

If you’re on a strict budget or just need basic protection for fans nobody can see, the premium price is hard to justify. Also, if you want decorative custom designs, these are purely functional with a clean industrial aesthetic.

10. SilverStone 120mm Honeycomb Fan Filter 2-Pack

The SilverStone 120mm honeycomb filters bring the same design philosophy as their 80mm option to the most popular fan size. The 2-pack provides good value, and the integrated dust filter behind the honeycomb grille offers solid dust protection without excessive airflow restriction.

The honeycomb pattern focuses airflow through the hexagonal openings rather than diffusing it randomly. I’ve found this particularly effective for intake fans where you want directed airflow into your case. The integrated filter material catches visible dust while still allowing good air movement. After months of use, the filter accumulates a satisfying layer of captured dust that would otherwise be inside your case.

Build quality is where the price point shows. These are plastic construction, not the metal some listings might suggest. They’re sturdy enough for their purpose, but there’s some flex if you press on them. For most installations where they just sit behind a fan, this doesn’t matter. For applications where they might be handled frequently, the flex could become a concern over time.

One important note: despite some listing confusion, these are not magnetic. They mount with the included screws. The screw mounting is secure but less convenient than magnetic options if you clean your filters frequently. For case modders adding 120mm fans to cases that didn’t originally have them, these work excellently as combined grills and filters.

For whom its good

Case modders, anyone adding fans to non-standard locations, and builders who want professional-looking dust protection without spending much will find these perfect. The 2-pack provides excellent value for multi-fan builds.

For whom its bad

If you specifically need magnetic mounting for easy removal, look elsewhere. Also, if you’re expecting metal construction based on some listing descriptions, you’ll be disappointed with the plastic build. For premium showcase builds, the plastic construction may not meet aesthetic standards.

Buying Guide: Choosing Custom Fan Grilles for Your PC Case

Selecting the right custom fan grilles and screens for PC cases involves balancing aesthetics, airflow performance, and practical considerations. After years of building and modding systems, I’ve developed a framework for making these decisions that I’ll share here.

Size Compatibility

The most critical factor is matching your grill size to your fans and case. Standard sizes include 80mm, 92mm, 120mm, 140mm, and 200mm for case fans. For water cooling, you’ll encounter 240mm, 280mm, and 360mm radiator sizes. Measure your existing fan mounts before ordering, as some cases have slightly non-standard dimensions. The MoKo DIY filter option is perfect for truly non-standard sizes since you can cut it to fit.

Material Selection

Each material offers different trade-offs. Aluminum provides premium durability and finish but costs more. Acrylic offers excellent customization and RGB reflection but can crack and restricts airflow more than mesh. PVC mesh maximizes airflow and dust filtration but lacks aesthetic appeal. 3D printed materials (not covered in our product list but popular on Etsy) offer maximum customization but potential durability concerns over time.

Airflow Considerations

Any grill will restrict airflow to some degree. Open mesh designs like the Noctua or SilverStone honeycomb maintain 90%+ of unrestricted airflow. Laser-cut acrylic with artistic patterns typically allows 70-85% airflow. Solid designs with minimal cutouts can restrict airflow by 30% or more. For intake fans in thermally constrained builds, prioritize airflow. For exhaust fans or builds with excess cooling capacity, you have more aesthetic freedom.

Mounting Options

Magnetic mounting, like the MoKo filters use, offers easy removal for cleaning but requires steel case surfaces. Screw mounting is universal and secure but less convenient for frequent cleaning. Push-pin mounting, as Noctua uses, offers tool-free installation with good security. Consider how often you clean your filters and your case’s material when choosing.

Placement Recommendations

I generally recommend using less restrictive grills on intake fans where airflow matters most. Decorative acrylic grills work well on exhaust fans or secondary case fans where reduced airflow has less thermal impact. Never install restrictive grills on CPU cooler fans, as the thermal consequences are immediate and significant.

For builds where you’re considering overall system integration, including compatibility with systems like the Steam Machine specifications, ensure your cooling solutions work with your intended hardware configuration.
