The screws are made from soft silicone and measure approximately 44 by 7.5 millimeters. Their flexible construction is intended to reduce the direct transfer of fan vibration into a case frame, which can also lessen structure-borne noise. The stated universal design is suitable for most fans, although buyers should still confirm that their frames and case mounting holes are compatible with this rivet-style format.
Twenty pieces provide enough material for five four-screw fan installations if all positions are used, although exact usage depends on the case and fan mounting pattern. The product is a black set, which suits dark or all-black builds better than visually contrasting hardware, and the screws can replace conventional case fan fasteners for a softer mounting point.
This is a sensible choice for buyers who want the core benefits of silicone fan mounting without moving to a more specialized system. It is particularly useful for a single case fan, a CPU cooler with matching holes, or a planned expansion that includes several fans. For broad compatibility, compare the stated dimensions with the supplied hardware before purchase and avoid assuming every screw pattern is interchangeable.
Flexible Noise-Control Hardware
The soft silicone body creates a less rigid connection between the fan and chassis than a conventional metal screw. That can reduce the transmission of vibration through the case frame, although it does not lower the fan's own airflow noise.
Useful Five-Fan Coverage
With twenty fasteners, the kit can cover up to five four-screw fan positions in principle. Real installations may use fewer positions because case layouts and some fan frames only use a subset of their mounting holes.

2. AUEAR 50-Pack 43mm – Flexible Multi-Fan Mounting
AUEAR 50-Pack 43mm
Fifty black rubber screws
Approx. 43 by 7.4mm
Universal compatible fan design
Case resonance reduction
The AUEAR 50 Pack is built for installations that need more mounting hardware than a small replacement kit provides. Its 4.5 rating indicates strong customer satisfaction, and the 50-piece count makes it a logical option for a multi-fan case, a new build, or keeping spare fasteners on hand for future additions.
Pros
- Large fifty-piece quantity
- Soft flexible rubber material
- Suitable for multiple fans
- Targets case-frame resonance
Cons
- Not all fan patterns are universal
- Rubber may collect visible dust

These black rubber rivet-style screws measure approximately 43 by 7.4 millimeters. According to the supplied information, they fit most compatible fans and are intended to reduce the noise created where a fan meets a case frame. The material provides a soft, flexible interface that can isolate resonance more effectively than rigid metal screws.
The main limitation is that universal does not mean interchangeable with every mounting arrangement. AUEAR's system is designed for compatible PC case fans and CPU fan mounting locations, but the frame must have suitable holes for the rivet-style fasteners. Buyers should also consider that exposed rubber can collect dust in a visible intake or exhaust position.
Overall, this set is a strong option for builders replacing several fan screws at once. Its generous quantity and simple vibration-isolating purpose make it more useful for broad installations than for a delicate all-black aesthetic project. Confirm hole compatibility and case clearance before fitting the rivets.
Built for Larger Fan Counts
Fifty pieces offer considerable installation flexibility and reduce the chance of running short while mounting multiple fans. They also work well as a maintenance kit for replacing worn or missing case fasteners.
Targeted Resonance Isolation
The flexible rubber pins are intended to interrupt the rigid connection that can allow fan vibration to become case resonance. The result is aimed at reducing transferred sound without replacing or modifying the fan itself.

3. 20PCS 65mm Fan Screws – Long Reach for Deep Frames
20PCS 65mm Fan Screws
Twenty black rubber screws
65mm overall mounting length
High-temperature resistant silicone
Universal open-case design
This 20-piece, 65mm fan-mounting set offers a notably long option for cases and frames with deeper mounting stacks. The product has a 4.5 rating and is designed to reduce vibration, shock absorption needs, and noise at the point where a compatible cooling fan meets its mounting surface.
Pros
- Long mounting reach
- Flexible aging-resistant material
- Supports most open-case fans
- Reduces vibration between components
Cons
- Long pins need adequate clearance
- Limited twenty-piece pack size
We may earn a commission when you buy through this link, at no additional cost to you.
The black soft rubber material is described as flexible, ultra-soft, aging resistant, and suitable for high-temperature use. At 65 millimeters, or 2.56 inches, these pins offer more reach than the shorter universal sets. That length may be useful when a fan must sit farther from a panel, but it also makes adequate clearance and correct hole alignment important.
The stated universal design fits most open-case fan sizes and PC cases, with convenient mounting and removal. It should not be read as support for every proprietary frame, however, because the rivet-style pins still require compatible holes and sufficient space behind the panel.
This kit is a good fit for builders with a deeper open-frame fan arrangement or a case where standard-length screws feel insufficient. Verify both the 65mm reach and the available internal clearance before ordering. For ordinary shallow cases, a shorter option may be easier to position and less likely to protrude awkwardly.
Length for Deeper Installations
The 65mm length distinguishes this set from the shorter 30mm, 43mm, and 44mm choices. It can be advantageous when a fan or mounting layer needs more travel, provided the enclosure has room behind it.
Flexible High-Temperature Material
The product information highlights silicone rubber that resists aging and remains usable in high-temperature areas. This makes the fasteners a natural fit for the warm environments commonly found around case fans and CPU cooling hardware.

4. 20PCS 22.7mm Mounts – Compact Tool-Free Installation
20PCS 22.7mm Mounts
Twenty black silicone pins
9 by 22.7mm dimensions
Elastic shock-absorbing material
Universal compatible case design
The 20PCS 22.7mm set provides a compact mounting-pin option for compatible case fans. Its 4.0 rating is the lowest among the featured products, but the available information still presents a clear purpose: flexible silicone hardware that cushions fan contact and helps reduce vibration-related noise.
Pros
- Compact dimensions
- Tool-free installation
- Flexible shock-absorbing material
- Suitable for multiple case fans
Cons
- Lowest listed rating
- Not designed for thick frames
We may earn a commission when you buy through this link, at no additional cost to you.
Each pin measures 9 by 22.7 millimeters and is made from flexible, elastic, ultra-soft silicone. The stated high-temperature stability and resistance to breaking are useful qualities for mounting hardware exposed to the internal airflow and heat around a PC chassis.
Installation is simple: the pin passes through the fan and case holes, then is pulled from the opposite side by hand. No screwdriver is required for the mounting operation itself. This convenient approach also makes removal and repositioning easier, provided the pin is not obstructed and the holes are correctly aligned.
This set is most appropriate for a case or fan with standard, relatively thin mounting points and enough access to grip the opposite end. It is less attractive for unusually thick frames because the compact pins have limited reach. Buyers should validate dimensions rather than relying on the universal label alone.
Compact Where Clearance Is Tight
The short 22.7mm mounting length can be helpful in confined cases where longer rivets might protrude or interfere with internal components. Compactness, however, is useful only when it still allows the full mounting point to seat correctly.
Quick Hand-Only Installation
The pull-through installation method removes the need for a screwdriver. It also makes the fasteners convenient to reposition, although adequate access behind the mounting panel is still necessary.

5. AUEAR 50-Pack 65mm – Ample Hardware for Large Builds
AUEAR 50-Pack 65mm
Fifty black rubber screws
65mm overall mounting length
Fits most compatible fans
Reduces case-frame resonance
The AUEAR 50 Pack 65mm combines a large hardware count with long mounting pins. Its 4.5 rating makes it one of the stronger-rated options in the roundup, while the combination of fifty pieces and 65mm length is particularly relevant to builds using numerous fans or frames with deeper mounting stacks.
Pros
- Generous fifty-piece quantity
- Long 65mm mounting reach
- Soft vibration-isolating material
- Useful for large fan installations
Cons
- Long pins need case clearance
- Compatible hole pattern required
We may earn a commission when you buy through this link, at no additional cost to you.
The black rubber rivets are described as a universal design for most compatible PC case fans and CPU fan mounting applications. Their soft construction is intended to reduce the noise between the fan and case frame and to reduce box resonance caused by fan vibration.
The primary consideration is clearance. A 65mm pin needs to travel through the fan holes and into the space behind the mounting panel without striking a drive cage, radiator, motherboard area, or other component. The rivet-style design also requires holes that can accept the pin's shaft and head.
This set is a practical choice for a new multi-fan build where maintaining a supply of replacement hardware is useful. It may be excessive for a single fan, but the additional pieces offer flexibility as the system expands. Measure the mounting stack and check hole compatibility before installation.
Future-Proof Fan Hardware
Fifty pieces are more than many compact builds need immediately, but that quantity makes it convenient to configure a larger case, replace several worn mounts, or keep spares for later fan additions.
Long-Pin Resonance Control
At 65mm, the rivets can bridge a deeper mounting gap while retaining the soft isolation intended to interrupt vibration transfer. Case depth and internal component positions determine whether that added reach is helpful or excessive.

Anti-aging high-temperature material
Universal chassis compatibility
The E-outstanding 20-piece set uses foamed silicone rubber mounting pins to soften the connection between compatible case fans and their frames. Its 4.6 rating is among the highest in the list, and the product information emphasizes aging resistance, vibration absorption, elasticity, and high-temperature use.
Pros
- High 4.6 customer rating
- Foamed silicone rubber construction
- Strong vibration absorption claims
- High-temperature aging resistance
Cons
- Twenty-piece fan coverage
- General-purpose hole matching

At 45mm, these black pins sit between the shortest 30mm options and the longer 65mm versions. That middle-range length can suit conventional case panels without the extreme reach of a long pin, while still offering enough travel for a compatible fan flange.
The stated universal design is intended for most open PC chassis fan sizes, and installation is described as quick and easy. As with other rivet-style products, exact frame patterns and hole sizes should be checked before purchase. A universal claim does not guarantee that every proprietary mounting arrangement will accept the pin.
This kit is a good general option for a builder focused on long-term material resilience and vibration isolation. The foamed silicone construction is presented as resistant to aging under sustained heat, while its large-deflection characteristics are intended to cushion fan movement. It is most valuable in a case where noise transfer and durability matter more than having a very large spare pack.
Foamed Silicone Construction
The listed foamed silicone rubber is softer and more compressible than rigid plastic fasteners. That compliance gives the mounting point room to absorb minor movement and reduces direct vibration transfer into the case.
Designed for Sustained Heat
The anti-aging process is specifically highlighted for prolonged high-temperature use. That is relevant in compact cases where airflow around mounted fans may keep nearby components consistently warm.

The Noctua NA-SAV4 stands apart from simple pull-through rivets with a more structured mounting system designed to decouple fans from a PC case. Its 4.4 rating reflects a well-regarded installation kit, while the 16 included mounts support up to four fans and add a clean, case-facing finish.
Pros
- Five supported fan thicknesses
- Flush case-side appearance
- Broad fan model compatibility
- Six-year manufacturer warranty
Cons
- Fewer pieces than fifty-pack options
- Not universal for all fan frames
We may earn a commission when you buy through this link, at no additional cost to you.
Five defined, numbered pawls accommodate standard open-corner fans at position one and closed-corner fans measuring 10, 14, 15, 20, or 25mm at positions two through five. This controlled approach is more specialized than relying on a single universal length, helping the mount sit correctly across a broader range of supported fan designs.
Its flat case-side end is intended to preserve a clean exterior appearance, and the silicone material works to reduce structure-borne noise by decoupling the fan from the chassis. Compatibility extends across Noctua fans and many third-party models, but the product is not presented as suitable for every possible frame shape.
This is the selection to consider when appearance, fan-thickness support, and a defined mounting method matter. The kit is particularly suitable for builds using Noctua hardware or third-party fans that meet the listed dimensional and hole requirements. Buyers should still match the mount position to the fan's flange thickness and confirm compatibility before fitting.
Defined Thickness Support
Rather than relying on a one-size dimension, the numbered pawls let the installer select a position for open-corner or closed-corner fans. This makes the kit useful across a wider range of supported fan constructions.
Cleaner Case-Facing Appearance
The flat case-side end is designed to sit neatly against an exterior panel. That clean finish is one of the most visible advantages over fasteners with a more protruding profile.

8. AUEAR 50-Pack 30mm – Short Hardware for Compact Cases
AUEAR 50-Pack 30mm
Fifty black rubber screws
30mm overall mounting length
Fits most compatible fans
Reduces case-frame resonance
The AUEAR 50 Pack 30mm provides a large collection of short mounting screws for compatible case and CPU fans. Its 4.5 rating is strong, and the 30mm length distinguishes it as a more compact option than the 43mm, 44mm, 45mm, and 65mm products in this guide.
Pros
- Large fifty-piece quantity
- Short 30mm mounting length
- Soft flexible rubber material
- Convenient multi-fan coverage
Cons
- Limited depth for thick frames
- Requires compatible rivet holes
We may earn a commission when you buy through this link, at no additional cost to you.
The black rubber pin rivets are intended to reduce noise at the connection between a fan and a case frame. Their flexible construction can interrupt the rigid vibration path associated with conventional screws, helping address case resonance without changing airflow or fan performance.
A shorter pin can be valuable in a compact case where internal clearance is limited. It may be less suitable for a deeper fan frame, however, because the mounting point must have enough engagement while still allowing the rivet to be pulled into position from the opposite side.
This product is a good match for a builder who wants many spare mounts or is configuring several compatible fans with shallow mounting stacks. The fifty-piece count is generous, but it should not substitute for checking dimensions. Hole size, fan flange shape, and available depth remain the decisive compatibility details.
Useful Short-Pin Geometry
The 30mm length is suited to standard, shallower mounting points and can help avoid excess protrusion inside a compact chassis. It provides a useful alternative to longer universal rivets when internal space is restricted.
Convenient Bulk Supply
Fifty screws are easy to use across a multi-fan build and leave a useful reserve for replacement. The black finish also blends naturally with dark fan frames and other internal hardware.

The Noctua NA-SAV2 is the premium conventional mounting kit in this roundup, combining a 4.7 customer rating with extra-soft, tear-resistant silicone rubber. Its 20 mounts support up to five fans, making it a well-balanced option for systems that need several isolated mounting points without carrying a much larger pack.
Pros
- Highest listed customer rating
- Premium tear-resistant silicone
- Convenient vibration-free installation
- Six-year manufacturer warranty
Cons
- Requires open-flange fan frames
- Limited to standard hole size
We may earn a commission when you buy through this link, at no additional cost to you.
The black mounts are designed for quick, vibration-free installation in standard PC case fan holes. They are compatible with most Noctua fans and third-party fans that have open flange frames and standard 4.3mm-diameter mounting holes. That specific requirement gives buyers a clear standard to check.
Premium-grade silicone rubber is described as extra soft and highly tear resistant, balancing compliance with durability. The all-black color also supports coordinated dark or chromax.black-themed builds, making the kit relevant to both performance and appearance-focused configurations.
This is the strongest premium recommendation for a compatible standard-hole fan installation, and the six-year manufacturer warranty adds meaningful support compared with generic rivet sets. It is not the right mount for a closed-corner fan or a nonstandard hole diameter, so verify the frame design first. For compatible hardware, it offers refined materials and clear compatibility standards.
Premium Softness and Durability
The extra-soft silicone is intended to provide effective decoupling while resisting tearing during installation and service. This combination of compliance and durability is the central reason to consider a premium mounting kit over a generic rubber pin.
Clear Compatibility Standard
Open flange frames with standard 4.3mm mounting holes are clearly identified as the intended format. This transparent requirement makes selection easier than interpreting a broad universal-fit claim without dimensional guidance.

PC Case Fan 50-Pack
Fifty black silicone rivets
Flexible tear-resistant material
Tool-free pull-through installation
Universal mounting design
The PC Case Fan 50-Pack is a high-rated bulk option for installing compatible case fans with flexible black silicone rivets. Its 4.7 rating places it alongside the Noctua NA-SAV2 at the top of the listed customer ratings, while its 50-piece count makes it especially attractive for a fan-heavy system.
Pros
- Highest listed customer rating
- Large fifty-piece quantity
- Flexible tear-resistant silicone
- Fast tool-free installation
Cons
- Broad compatibility requires validation
- Exact dimensions are not listed
We may earn a commission when you buy through this link, at no additional cost to you.
The material is described as high-quality silicone rubber that is flexible, extra soft, and highly tear resistant. It is also described as anti-aging and suitable for high-temperature use, targeting the long-term durability expected of mounting hardware inside a warm, active computer case.
Installation requires no screwdriver. A rivet passes through the fan and case holes and is then pulled firmly by hand from the opposite side. This quick method also makes removal and repositioning convenient, assuming the user can access the reverse side of the mounting panel.
The stated universal design is suitable for most open fan sizes and case arrangements, but the product data does not provide a precise overall dimension. Buyers should therefore compare the physical rivet with their fan holes and mounting gap. For a builder who wants a large supply of soft, durable mounts and accepts standard rivet-style installation, this is a compelling option.
Soft Yet Tear-Resistant
The stated material balance allows the rivets to deform for vibration isolation without being as vulnerable to tearing as a very soft alternative. It is a practical combination for repeated installation and long-term use.
Fast Serviceable Installation
The pull-through method allows a fan to be mounted or removed without a screwdriver. This is helpful for initial builds and future maintenance, provided the mounting location is accessible from behind.

Buying Guide – How to Choose the Best PC Fan Silicone Screws
The right fan-mounting hardware depends on fan geometry, available clearance, case design, and the noise-control approach you prefer. Compare dimensions and compatibility language carefully rather than treating every silicone or rubber pin as interchangeable.
Fan Flange Compatibility
Begin with the fan's frame construction. Some fans have open corners and standard circular mounting holes, while others have closed corners that conceal the holes. The Noctua NA-SAV2 explicitly supports open-flange fans with standard 4.3mm holes, and the NA-SAV4 adds defined positions for several closed-corner thicknesses. Generic universal products may work across many common frames, but their wording does not guarantee support for every proprietary arrangement.
Overall Pin Length
Length determines how far the mounting pin can pass through the fan and case panel. The selection includes a 22.7mm option, 30mm and roughly 43mm to 45mm options, and 65mm pins. Short products can be easier to fit inside compact cases, while longer pins suit deeper mounting stacks. The correct length must provide sufficient engagement without colliding with internal components behind the panel.
Material Flexibility
Silicone and rubber are the central materials because they can cushion vibration rather than creating a rigid bridge between the fan and chassis. The Honbay, AUEAR, and generic 50-pack options are described as flexible or extra-soft, while the Noctua NA-SAV2 is specifically described as premium-grade, extra-soft, and highly tear resistant. E-outstanding uses foamed silicone rubber, and several other products emphasize aging and high-temperature resistance.
Case and CPU Fan Scope
Many of the products are described as suitable for PC case fans and CPU fans, but CPU coolers may use different mounting hardware from standard case fans. Check the cooler frame, screw-hole size, and required mounting accessories before assuming a case fan rivet will work. Fans with open corners and standard 4.3mm holes are the clearest fit for the explicitly documented Noctua NA-SAV2 system.
Pack Quantity and Coverage
Pack size affects convenience rather than sound-reduction capability. Twenty-piece kits can cover up to five four-screw fans in principle, although many installations use only two screws per fan. Fifty-piece kits provide a useful reserve for multi-fan cases, replacement hardware, and future expansion. The Noctua NA-SAV4 has 16 mounts because its installation uses a different mounting structure, so counting pieces should be done alongside checking the system design.
Installation Access
Most pull-through rivets are installed by hand: the pin passes through the fan and case holes, then is pulled from the opposite side. This requires access behind the panel and enough room to grip the pin. A screwdriver may still be needed to remove the fan from a bracket or to complete a separate CPU-cooler mounting procedure. The NA-SAV4's pawl-based system is more specialized and should be matched carefully to fan thickness.
Visual Finish
Most of the products use black hardware that blends with dark cases, fan frames, and all-black internal builds. The Noctua NA-SAV4 adds a flat case-side end for a cleaner exterior appearance, while the NA-SAV2 is explicitly associated with chromax.black styling. Color does not affect the basic vibration-isolating function, so appearance should be weighed after compatibility and fit.
Warranty and Brand Support
The two Noctua kits include a six-year manufacturer warranty, providing a notable distinction from generic rivet sets. A warranty does not change the core installation method, but it can provide confidence in material longevity and product consistency. Generic options may offer broader cost efficiency and larger quantities, while the branded kits provide more explicit fan compatibility and support.
How to Use and Care for Your PC Fan Silicone Screws
Before installation, power down the computer, unplug the power cable, and hold the power button briefly to discharge remaining power. Remove the side panel, note the fan's current position, and disconnect its power cable. Confirm that the silicone mount's dimensions match the gap between the fan frame and case panel.
For a pull-through rivet-style product, align the fan in its intended position and insert one silicone pin through a fan hole and the corresponding case hole. Continue pulling the pin from the reverse side until the mounting point seats securely, then repeat for the remaining required holes. Work around the frame gradually so the fan remains square rather than being forced into alignment.
Reconnect the fan, route its cable away from sharp edges and rotating components, and replace the side panel. Periodically inspect exposed mounts for cracking, deformation, looseness, or accumulated dust. Replace damaged pieces as a set when possible, and avoid pulling on a mount at an angle that could tear the silicone.
Frequently Asked Questions
Do silicone fan screws reduce the noise produced by the fan itself?
They primarily reduce vibration transferred from the fan to the case. This can lower structure-borne noise or case resonance, but it will not reduce airflow noise generated by the fan blades or motor. A quieter fan and suitable airflow configuration are still needed for lower overall acoustic output.
Are all PC fan silicone screws interchangeable?
No. Fan frames differ in corner design, hole diameter, and frame thickness. Some products explicitly support standard 4.3mm holes, while others are designed around longer rivet-style pins or selected closed-corner thicknesses. Compare the mounting dimensions and the case's available depth before buying.
Can I use these screws for a CPU cooler?
Only when the CPU cooler's frame and mounting system are explicitly compatible. The product descriptions mention CPU fan use for several generic sets, but CPU coolers may require their own bracket, screws, or a different hole pattern. Confirm the cooler's mounting instructions before replacing any original hardware.
How many screws are needed for one case fan?
Many case fans use four mounting holes, while some positions are fixed with only two screws. A 20-piece kit can therefore cover as many as five four-hole fans if every hole uses a mount, although practical cases often use fewer positions. Check the actual number of holes used in your case.
Do silicone mounting screws require a screwdriver?
The pull-through products in this guide are described as installable by hand without a screwdriver. You push the rivet through aligned holes and pull it from the opposite side. A separate screwdriver may still be needed to remove a bracket or disconnect another component, and the Noctua NA-SAV4 follows its own specialized mounting procedure.
What is the difference between 30mm, 45mm, and 65mm mounting screws?
The main difference is the depth they can bridge between the fan frame and the case panel. Short mounts suit shallower configurations, while longer mounts can accommodate deeper frames or gaps. The correct choice also depends on whether the mounting hole is reached from the front or rear and what components sit behind it.
Will rubber fan mounts affect cooling or airflow?
The mounts are intended to secure the fan in the same position as ordinary fasteners, so they should not materially change airflow when correctly installed. A loose, stretched, or incorrectly sized mount could allow movement, so each pin should seat firmly and the fan should remain properly aligned.
How do I keep the silicone mounts from looking dusty?
Exterior-facing rubber can collect dust, especially in open-frame cases. Keep the case filters clean, avoid placing the mounts where airflow constantly exposes them to visible dust, and gently wipe compatible parts with a dry cloth during routine servicing. Do not use aggressive chemicals that may degrade the silicone surface.
Final Thoughts on Choosing the Best PC Fan Silicone Screws
The Honbay 20-piece set is a practical budget choice for a basic compatible installation, while the Noctua NA-SAV4 offers the most specialized support for different fan thicknesses and a clean case-facing finish. The Noctua NA-SAV2 stands out as the premium conventional option, with extra-soft tear-resistant silicone, clearly stated hole compatibility, and a six-year warranty.
For other builds, the AUEAR kits provide useful choices in 30mm, 43mm, and 65mm lengths, while the E-outstanding and generic 50-pack options prioritize flexible, aging-resistant silicone and generous quantities. Prioritize correct hole style, pin length, and internal clearance before pack size, color, or broader compatibility claims.
Current prices and availability can change, so compare the complete specifications at the time of purchase. In every case, confirm that the mounting style suits the fan frame and that the hardware is installed fully enough to hold the fan securely without creating internal interference.
