This kit is especially attractive for all-black systems because the black components blend naturally with black fans, frames, and case interiors. It also remains practical for mixed systems since the mounts work with most Noctua fans and many third-party fans that have open flange frames and standard 4.3mm mounting holes.
The principal limitation is that the NA-SAV2 is not intended for fans with closed corners or unusual mounting-hole arrangements. It also supplies mounts for up to five fans, so unusually large cooling configurations may require another kit. These are compatibility boundaries rather than quality concerns, and most standard case fans fit the stated design.
This is the strongest general recommendation for builders seeking a proven combination of isolation, refined appearance, broad standard-fan compatibility, and straightforward installation. Choose it when your fans use conventional open corners and you want the mounting hardware to coordinate with a dark build.
Vibration Decoupling Without Visual Clutter
Soft silicone separates the fan frame from the case at each mounting point, reducing structure-borne vibration while remaining visually discreet. The black finish makes the mounts nearly disappear against dark components.
A Sensible Multi-Fan Package
Twenty individual mounts cover up to five four-corner fans, making the set useful for intake, exhaust, and auxiliary cooling positions. Check the frame design of every fan before installation to avoid compatibility surprises.

2. Noctua NA-SAV4 – Best for Flush Installation
Noctua NA-SAV4
Sixteen silicone anti-vibration mounts
Up to four supported fans
Flat case-side mounting end
Five numbered corner pawls
The Noctua NA-SAV4 is a premium mounting solution with a 4.4 rating and a particularly refined installation concept. Its 16 silicone mounts support up to four fans and are designed to reduce structure-borne noise by mechanically decoupling the fan from the PC case.
Pros
- Clean flush case-side appearance
- Supports closed-corner fan designs
- Multiple numbered pawl positions
- Works with all Noctua fans
- Six-year manufacturer warranty
Cons
- Lower rating than top selection
- Covers fewer fans than NA-SAV2
We may earn a commission when you buy through this link, at no additional cost to you.
The defining feature is the flat case-side end, which creates a clean exterior when the fan is fitted directly against the panel. Five defined, numbered pawls expand the range of supported frames: pawl 1 serves standard open-corner fans, while pawls 2 through 5 accommodate closed-corner fans of 10, 14, 15, 20, or 25mm thickness.
The trade-offs are that the NA-SAV4 has fewer mounts than the NA-SAV2 kits, and its rating is lower despite the more specialized mounting design. Buyers with open-frame fans may also prefer the simpler NA-SAV2, whereas those needing a flush appearance or thicker closed-corner fan benefit from the NA-SAV4's numbered positions.
This is the premium choice for builders who prioritize a polished exterior, broad frame support, and organized installation. It is particularly well suited to a carefully coordinated case where the fan mount should look integrated rather than visibly raised.
A Cleaner Exterior Fan Profile
The flat case-side end keeps the mounting hardware close to the panel, reducing the visual bulk of a direct-mounted fan. This is useful for minimalist cases, tempered-glass views, and exterior intake or exhaust positions.
Adaptable Support for Fan Frames
Numbered pawls make frame thickness easier to match because the correct position can be selected systematically. Confirm both the corner style and physical thickness of your fan before fitting a pawl.

Its universal design is intended to fit most fans, while the rubber construction helps isolate fan movement from the case. The stated dimensions are 11 by 30mm, with 30mm representing the maximum length and 11mm the maximum diameter.
The main compromise is that this is a straightforward rivet-style mounting system rather than a color-coordinated or flush-mounting kit. Clearance around the mounting hole is important because the longer screws may require more space than a conventional short anti-vibration pad. The product information also does not provide the same detailed frame-thickness guidance offered by the Noctua NA-SAV4.
This is the best-value pick for a builder who wants generous quantities, fast mounting, and broad fan compatibility. It is especially useful for multi-fan systems where enough fasteners are needed for several exhaust and intake positions without purchasing separate kits.
Ample Hardware for Large Builds
Forty screws offer useful flexibility for high-airflow cases with numerous fans. The quantity can also provide replacement pieces if a fastener is damaged during repeated installation.
Rubber Isolation in a Familiar Format
The rivet-style format is recognizable and straightforward to install in compatible holes. Position the flexible insert fully and check that the fan cannot shift before tightening it.

4. 20PCS Soft Rubber Fan Mounts – Best for Long Rivet Clearance
20PCS Soft Rubber Fan Mounts
Twenty soft silicone screws
Sixty-five millimeter overall length
High-temperature resistant construction
Universal open-case fit
This 20-piece kit has a 4.5 rating and focuses on long, soft silicone rivet-style mounts. At 65mm, or 2.56 inches, it is the longest mounting product in the comparison, making it potentially useful for cases with deeper fan mounting holes or less conventional spacing.
Pros
- Long mounting pins fit deeper holes
- Flexible silicone absorbs vibration
- Material resists high temperatures
- Supports quick removal
- Helps reduce case resonance
Cons
- Longest listed mount length
- May not suit shallow mounting areas
We may earn a commission when you buy through this link, at no additional cost to you.
The stated material is flexible, ultra-soft, aging-resistant silicone rubber that is also described as suitable for high-temperature use. Its intended function is to replace ordinary fan fixing screws, absorb fan-to-case vibration, and reduce resonance transferred through the chassis.
The long length is both the main advantage and the main constraint. It may be less convenient in a shallow panel, near a motherboard tray, or wherever the inside of the case offers limited clearance. Because the product information says it fits most open-case fan sizes, it should be considered a more specialized choice than a compact four-corner pad system.
This kit is worth considering when ordinary short screws do not provide sufficient reach or when your mounting area can accommodate a long pin. Verify the available depth before installation and ensure the fan is fully supported once the rivet is seated.
Extended Reach for Deep Mounting Holes
The 65mm length offers more insertion depth than the other rivet-style kits in the list. That can make it useful in cases with unusually deep or recessed mounting points.
Flexible High-Temperature Material
The soft silicone is described as flexible, aging resistant, and usable in high-temperature environments. These properties make it well suited to the varying conditions around PC cooling hardware.

We may earn a commission when you buy through this link, at no additional cost to you.
Each fastener measures approximately 44mm in length with a maximum diameter of 7.5mm. The soft silicone construction is intended to reduce noise by absorbing movement and minimizing the transfer of vibration between the fan and the case frame.
Compared with the 40-piece Honbay option, this kit provides fewer mounting screws and therefore suits more moderate fan counts. It is also shorter than the 65mm rivet product, which may make it easier to install in confined spaces, although exact clearance still depends on the case and fan frame.
This is a sensible option for a builder who wants a straightforward universal silicone system without choosing a highly specialized mounting format. It works particularly well for mixed case-fan and CPU-fan projects, provided the listed dimensions suit the available mounting holes.
Practical Dimensions for Common Fans
The compact 44mm length offers a balance between insertion depth and ease of placement. Check the mounting-hole depth and fan frame before beginning installation.

Each mounting piece measures approximately 43mm long and 7.4mm in maximum diameter. The silicone rubber is intended to reduce noise between the fan and the case frame, while the universal design is stated to fit most fans and work with PC cooling hardware or CPU fans.
Its limitations are shared with other universal rivet-style systems: it does not offer the numbered frame-thickness selection of the NA-SAV4, and it is less visually integrated than a flush mounting kit. The black components are practical but intended to blend into conventional dark hardware rather than serve as a color accent.
This product is ideal for high-fan-count systems, multi-case builders, or anyone who prefers to have extra vibration-isolating hardware on hand. Confirm that the mounting format and 43mm length are appropriate before using it on a specific frame.
Maximum Hardware for Expanding Builds
Fifty pieces can support numerous fan positions and leave extras for future upgrades or replacements. The large pack count is especially useful for cases with several intake and exhaust zones.
Resonance Control Through Rubber
The soft rubber separates fan movement from the case frame, reducing the transfer of structure-borne noise. The result is a straightforward approach to quieter mounting without complex installation hardware.

The Noctua NA-SAV2 chromax.White is the color-focused member of the 20-mount NA-SAV2 family. It carries a 4.7 customer rating and uses the same extra-soft, tear-resistant silicone construction intended to reduce vibration while preserving a secure fan position.
Pros
- Coordinated white appearance
- Extra-soft tear-resistant silicone
- Broad standard-fan compatibility
- Quiet-oriented mounting design
- Six-year manufacturer warranty
Cons
- Only suits open flange frames
- White may clash with dark builds
We may earn a commission when you buy through this link, at no additional cost to you.
Its white finish is designed for black-and-white themed systems and can coordinate particularly well with white Noctua fans, pale components, and clean case interiors. Functionally, the 20 mounts cover up to five fans and fit most Noctua products and many third-party fans with open flange frames and standard 4.3mm holes.
This is not the right aesthetic for a predominantly dark build, where visible white parts could interrupt the intended color scheme. As with other NA-SAV2 versions, it does not address closed-corner fans, so frame compatibility must be checked before buying.
This version is the best fit for a light-themed builder who wants proven anti-vibration hardware without sacrificing visual coordination. It combines the same practical mounting approach as the black NA-SAV2 with a distinctive finish suited to white components.
Color Coordination Without Sacrificing Function
The white silicone is designed to blend into black-and-white build themes while retaining the isolation performance of the NA-SAV2 platform. It is a more intentional visual choice than a generic black insert.
Familiar Standard-Fan Compatibility
The mounts fit most open-flange fans with standard 4.3mm mounting holes. They are particularly convenient for Noctua installations and compatible third-party fans that follow the same pattern.

8. Noctua NA-SAV2 – Best for Constrained Installations
Noctua NA-SAV2
Twenty premium rubber mounts
Up to five supported fans
Double-sided installation design
Standard 4.3mm mounting holes
The standard Noctua NA-SAV2 has a 4.3 rating and focuses on the same core objective as its color variants: reducing fan vibration with soft, tear-resistant rubber mounts. The 20-piece set supports up to five fans and fits most Noctua fans and many third-party products with open frames.
Pros
- Double-sided design eases installation
- Helpful in space-restricted cases
- Extra-soft tear-resistant rubber
- Works with many third-party fans
- Six-year manufacturer warranty
Cons
- Lowest listed customer rating

We may earn a commission when you buy through this link, at no additional cost to you.
Its distinguishing installation feature is the double-side design, which the product information identifies as easier to work with in space-restricted environments. That makes this version a practical option when a conventional tool cannot comfortably reach a mounting point or when access around the fan is limited.
The 4.3 rating is the lowest among the Noctua NA-SAV2 versions in this comparison, although all four remain rated above four. The other limitation is the same open-flange requirement found across the standard NA-SAV2 family, making this unsuitable for certain closed-corner fan frames.
This is a strong choice for tight PC layouts where installation access matters more than a specific accent color. It delivers Noctua's established mounting approach, a useful five-fan quantity, and a design that simplifies work in confined spaces.
Better Access in Tight Layouts
The double-sided configuration reduces the need to reach one side of the mount during installation. This can be valuable behind motherboard trays or near crowded component layouts.
Proven Material and Support
The premium rubber is described as extra soft and highly tear resistant, while the manufacturer backs the kit with a six-year warranty. These details make it a dependable choice for long-term PC use.

9. Noctua NA-SAV2 chromax.Blue – Best for Blue Accent Builds
Noctua NA-SAV2 chromax.Blue
Twenty premium silicone mounts
Up to five supported fans
Standard 4.3mm mounting holes
Six-year manufacturer warranty
The Noctua NA-SAV2 chromax.Blue combines a 4.7 rating with a distinctive color option for blue-and-black systems. Like the black and white versions, it includes 20 extra-soft, tear-resistant silicone rubber mounts for up to five fans.
Pros
- Distinctive blue accent finish
- Soft tear-resistant silicone
- Easy vibration-reducing installation
- Broad standard-fan compatibility
- Supports up to five fans
Cons
- Limited to open flange frames
- Blue suit depends on theme
We may earn a commission when you buy through this link, at no additional cost to you.
The blue finish is intended to coordinate with Noctua chromax or industrialPPC line fans and complement builds that use blue as a deliberate accent. Beyond appearance, the kit offers the same practical installation approach: standard 4.3mm mounting holes and compatibility with most Noctua fans and many third-party open-flange models.
The color is less neutral than black or white, so it may not blend into every chassis. The kit also cannot address closed-corner fans, and the 20-piece count may be insufficient for very large configurations. Buyers should therefore judge both aesthetic compatibility and fan-frame design.
This is a compelling choice for a builder who wants anti-vibration mounting to contribute to the overall color story. It is equally practical to a standard black build, but the blue accent makes it most satisfying when coordinated with matching cooling hardware.
A Purposeful Accent Color
The blue mounts give a standard anti-vibration installation a more intentional appearance. They are a natural match for blue-and-black themes and can be repeated across the case for visual consistency.
Quiet Mounting Without Complexity
The straightforward 20-piece configuration provides effective isolation for ordinary PC fan layouts. Installation remains uncomplicated as long as every fan has an open flange and standard 4.3mm holes.

Six-year manufacturer warranty
The Noctua NA-SAV2 chromax.red is the final color option in this comparison and carries a 4.7 customer rating. Its red silicone mounts are designed for red-and-black themed builds, providing a coordinated alternative to the black, white, blue, and standard versions of the mounting kit.
Pros
- Ideal red-and-black color pairing
- Extra-soft tear-resistant silicone
- Simple mounting process
- Works with many third-party fans
- Generous five-fan capacity
Cons
- Open-frame fans only
- Red finish is theme-specific
We may earn a commission when you buy through this link, at no additional cost to you.
The technical design remains consistent with the NA-SAV2 family. There are 20 extra-soft, tear-resistant silicone mounts, enough for up to five fans, and the kit fits most Noctua fans plus many third-party fans with open flange frames and standard 4.3mm mounting holes.
Its aesthetic is naturally specific, which may be a benefit or a drawback depending on the build. Like the other NA-SAV2 versions, it cannot be assumed to support closed-corner fans. Those two checks should be completed before installation to avoid an unsuitable purchase.
This is the ideal choice for a red-and-black system in which cooling hardware and mounting hardware are meant to look like a coordinated set. It combines a popular accent color with a straightforward, well-specified anti-vibration mounting solution.
Coordinated Red-and-Black Hardware
The red finish is specifically intended to complement red-and-black build themes. It can make otherwise hidden mounting points feel like part of the case's visual design.
Reliable Isolation for Standard Fans
The extra-soft silicone reduces direct contact between the fan frame and the case. Broad support for standard open-flange fans makes it a versatile option within those parameters.

Buying Guide – How to Choose the Best PC Anti Vibration Fan Mounts
The right anti-vibration fan mount depends on frame geometry, case clearance, quantity, and visual preferences. Review these factors before buying so the hardware fits both the fan and the case without compromising support or ease of installation.
Fan Frame Compatibility
Start by identifying whether each fan has an open flange or a closed-corner design. Noctua's NA-SAV2 mounts are intended for open frames with standard 4.3mm diameter mounting holes, while the NA-SAV4 uses numbered pawls to support open-corner fans and specific closed-corner thicknesses. Universal rivet-style kits may fit many fans, but their broad claims still require checking the frame shape, hole diameter, and available depth.
In short, match the mount to the exact frame design and hole standard before making a purchase.
Mounting Style and Clearance
Anti-vibration hardware comes in pad-style, flush-style, and rivet-style formats, each with different space requirements. The NA-SAV4 sits flush against the case, the standard NA-SAV2 uses a double-sided arrangement, and the Honbay, AUEAR, and 65mm kits use elongated pins. Measure nearby components, motherboard-tray features, and the available mounting-hole depth, especially in compact cases.
Choose a format that fits the available clearance and can be installed without forcing the fan against surrounding parts.
Material and Resilience
Soft silicone rubber or silicone-rubber construction is central to vibration isolation because it absorbs small movements rather than creating a rigid connection between the fan and chassis. The products in this guide describe their materials as soft, flexible, tear resistant, aging resistant, or suitable for high-temperature use. These characteristics matter because fan mounts remain under repeated mechanical and thermal stress inside a working PC.
Prioritize supple, resilient material that is specifically designed to remain in place without becoming brittle or permanent.
Quantity and Fan Count
A standard fan normally requires four mounting points, but the exact number of pieces supplied and the number of fans they support are not always the same across product formats. Noctua's 20-piece NA-SAV2 kit supports up to five fans, the 16-piece NA-SAV4 supports up to four, and the universal screw sets contain 20, 40, or 50 pieces. Count every intended case fan and include the CPU cooler if the mounting format is suitable.
Select enough hardware for every planned position, plus a few extras if you may expand the build later.
Noise-Reduction Design
A useful anti-vibration mount reduces structure-borne noise by mechanically decoupling the fan frame from the case. This is different from reducing the airflow noise produced directly by rotating blades. Quality materials, complete support at each corner, and a stable fit all contribute to effective isolation, while a loose or uneven installation can allow movement that undermines the result.
Look for soft components that maintain tension and keep the fan centered rather than relying only on a general noise-reduction claim.
Case Aesthetics
Anti-vibration mounts may remain visible around the edges of a fan, making color part of the practical buying decision. Noctua offers black, white, blue, and red NA-SAV2 versions, while the NA-SAV4 and the universal rubber rivet kits emphasize a more understated installation. Match the mounting hardware to the fans, case interior, and any accent lighting you plan to use.
Choose a coordinated color when the mounting points will be visible, and a neutral option when discretion matters more.
Installation and Maintenance
The ideal kit should be quick to install and remove without cracking, deforming, or pulling out of the mounting hole. The listed products use either corner pads with a clear insertion method or flexible pin rivets pressed into a fan screw hole. Consider whether you will need to remove the fan regularly for cleaning, and ensure the mount can be installed and removed repeatedly with the intended tools.
Select hardware that supports repeatable servicing and does not require force that could damage the fan frame or case.
Warranty and Brand Support
The Noctua kits in this comparison include a six-year manufacturer warranty, which adds confidence for components expected to remain installed for years. Other products provide detailed material and dimensional information but do not list warranty coverage in the supplied data. A longer warranty can be valuable in an unobtrusive internal part because it reduces the likelihood of replacing a failed mounting point and disturbing the system.
Consider warranty coverage alongside fit, material, and quantity rather than treating it as the only deciding factor.
How to Use and Care for Your PC Anti Vibration Fan Mounts
Before installation, switch off the computer, disconnect the power, and let the system cool. Identify each fan's mounting holes, confirm that the chosen mount supports the frame style, and clear any obstructions around the case panel. Clean and dry both the fan frame and mounting surface so dust or oily residue does not affect the fit.
Insert each anti-vibration component according to its design. For pad-style mounts, press the center into the fan hole and expand the outer section into the case opening. For rivet-style screws, pass the pin through the fan hole and press or secure its flexible outer section into the case. Seat every corner evenly so the fan remains square and fully supported.
Reconnect the fan, route its cable safely, and close the case before operating the system. Check alignment, clearance, and airflow after installation. If the fan rocks, shifts, or sits unevenly, power down and correct the mounting rather than tightening the fan frame against the case.
Frequently Asked Questions
Do anti-vibration fan mounts reduce PC noise?
They can reduce structure-borne noise by preventing fan vibration from transferring directly into the case panels. They do not reduce the airflow noise generated by spinning blades, so a noisy fan may still need replacement or better acoustic isolation. The improvement also depends on a complete, even installation with all mounting points properly engaged.
Can I use anti-vibration mounts on any PC fan?
Not every mount is compatible with every fan. The standard Noctua NA-SAV2 requires open flange frames and standard 4.3mm mounting holes, while the NA-SAV4 supports specified closed-corner thicknesses. Universal rivet-style kits may fit many fans, but you should still check hole diameter, frame shape, and the depth available behind the mounting point.
Are Noctua NA-SAV2 mounts compatible with third-party fans?
Yes, the supplied information says the NA-SAV2 is compatible with most Noctua fans and many third-party fans that have open flange frames and standard 4.3mm diameter mounting holes. Third-party fans with closed corners, unusual holes, or proprietary mounting systems may require a different kit or the manufacturer's original hardware.
What is the difference between NA-SAV2 and NA-SAV4?
The NA-SAV2 is a 20-piece kit that supports up to five fans with open flange frames and standard 4.3mm holes. The NA-SAV4 contains 16 mounts for up to four fans, provides a flat case-side end, and uses five numbered pawls to accommodate open-corner fans and several specified closed-corner thicknesses. The NA-SAV4 is therefore better suited to flush appearance and more varied frame designs.
Are longer rubber fan screws always better?
No. A longer mount may reach deeper mounting holes, but it can also require more clearance and become inconvenient near a motherboard tray or other component. The best length is the one that securely fills the available mounting space without forcing the fan into an angled or uneven position.
How many mounts do I need for my PC?
Count the intended fan positions rather than only the case fans. Most standard fans use four corner mounts, but product packs are not always organized as four complete sets. Noctua lists its 20-piece NA-SAV2 as supporting up to five fans, while the 16-piece NA-SAV4 supports up to four. Confirm the exact format and quantity before buying.
Do these mounts change fan speed or cooling performance?
Anti-vibration mounts are not designed to change a fan's rated speed or airflow specification. Their purpose is to isolate vibration, although a loose or poorly seated mount can affect alignment and should be corrected. Fans should still operate within their manufacturer's voltage and control specifications.
Can I use anti-vibration screws for a CPU cooler?
Several products in the comparison specifically list compatibility with CPU fans, but CPU coolers use varied mounting systems and should not be assumed to work with every case-fan fastener. Check the cooler manufacturer's instructions, confirm the required diameter, and ensure the replacement mount will not interfere with heatsink hardware or the four-point retention system.
Final Thoughts on Choosing the Best PC Anti Vibration Fan Mounts
The Noctua NA-SAV2 chromax.Black is the strongest all-around recommendation because it combines a 4.7 rating, soft silicone isolation, broad standard-fan compatibility, and a coordinated finish. The NA-SAV4 stands out for flush installation and broader support for selected closed-corner fans, while the Honbay 40-piece kit offers a generous quantity and a practical universal format.
Prioritize compatibility before appearance. Confirm the fan's flange design, mounting-hole diameter, frame thickness, and available clearance, then choose the mounting method that suits the case. A correctly sized and evenly installed mount will serve the system's cooling layout better than a larger kit with features the hardware does not need.
Finally, check the current listing, specifications, compatibility notes, and pricing before ordering. Product details and prices can change over time, and verifying the latest information helps ensure the selected PC Anti Vibration Fan Mounts still match the fans, case, and build design you have in mind.
