The Noctua NA-SAV3 is our pick for the best anti-vibration PC fan mounts because its numbered positions accommodate both open-corner and several closed-corner fan frames. Choose the NA-SAV2 chromax.black for a black open-corner build, or the NA-SAV4 if a flush case exterior matters more than pulling from both sides.
How anti-vibration PC fan mounts differ
A spinning case fan can transmit vibration through rigid screws into a metal panel. A soft silicone mount separates those surfaces, which can reduce a resonant buzz when the panel is the source. It cannot fix turbulent airflow, a worn bearing or a cable touching the blades. We compared Noctua's published specifications and installation guidance, rather than claiming a hands-on noise test.
All three kits replace case fan screws and use soft silicone. The differences are how the mount grips the fan, how much access it needs and what remains visible outside the case. A four-corner installation uses four mounts per fan. Count your fans and check their frame geometry before deciding whether one pack is enough.

The three mounts compared
Noctua NA-SAV3 fan mounts
The NA-SAV3 is the most adaptable choice when a gaming PC mixes conventional and slim case fans. Its 16 brown silicone mounts cover four fans at four corners each. Five numbered positions accommodate standard open corners as well as closed-corner frames in the 10, 14, 15, 20 and 25 mm thicknesses specified by Noctua. The double-sided shape provides a pulling end on either side, useful where the chassis restricts your fingers. That combination earns the overall badge for builders who may change fan sizes later. The long ends are more visible than the NA-SAV4's flat exterior, however, and four-fan capacity leaves no spares if all 16 positions are occupied. Confirm your exact fan frame and hole access before installation; the mounts do not correct noise caused by airflow itself.
Pros
- Numbered positions accommodate specified slim and closed-corner frames
- Double-sided ends offer a grip from either side of the panel
- Sixteen mounts cover four fans at four corners each
Cons
- Brown ends remain more visible on the exterior than flush NA-SAV4 ends
- A four-fan installation uses the entire pack
Noctua NA-SAV2 chromax.black fan mounts
The NA-SAV2 chromax.black suits a builder with standard open-flange fans and a dark case who wants to replace several sets of metal screws at once. The kit contains 20 black silicone mounts, enough for five four-corner fans. Noctua specifies compatibility with its fans and many third-party open-flange designs using standard 4.3 mm mounting holes. Its double-sided form offers a pulling end on both sides, which can make awkward case positions easier to reach. It earns the open-corner badge for combining that access with a larger pack and black finish. The limitation is fit: do not assume it will handle a closed-corner or unusually slim frame just because the fan is a common diameter. Check the frame and use an appropriately specified mount for those installations.
Pros
- Twenty black mounts cover five four-corner fans
- Double-sided design helps when a mounting point is awkward to reach
- Designed for standard 4.3 mm open-flange mounting holes
Cons
- Closed-corner frames need a compatible alternative
- Pull-through ends do not sit flush with the outside of the case
Noctua NA-SAV4 fan mounts
Choose the NA-SAV4 when the visible side of the chassis matters. Its flat case-side end sits flush against the panel, unlike the projecting ends of the double-sided NA-SAV3 and NA-SAV2. The pack has 16 brown silicone mounts, enough for four fans, and the five numbered positions support standard open corners and the specified 10, 14, 15, 20 and 25 mm closed-corner frames. That combination earns the flush-exterior badge without giving up the more flexible frame support. The tradeoff is practical: the single-sided design does not offer the same pulling access from both sides in a cramped build. Plan the installation around the available space, and remember that the brown finish may still be visible against a dark panel.
Pros
- Flat case-side ends leave a tidier exterior
- Five positions support specified slim and closed-corner frames
- Sixteen silicone mounts secure four four-corner fans
Cons
- Single-sided design offers less pulling access in tight placements
- Brown finish can contrast with a black case
Fit and installation priorities
First identify whether the fan has open corners or a closed tunnel between its mounting holes. Measure the frame thickness and compare it with the maker's compatibility guidance, rather than relying on the fan's 120 mm or 140 mm diameter alone. For the NA-SAV3 and NA-SAV4, use the numbered position appropriate to the frame; consult Noctua's installation sheet before pulling the mount into place.
Power down and unplug the PC before opening it. Make sure a mount can be reached on the relevant side and that no loose end can touch a blade. Keep the fan aligned while fitting all four corners. If the case still buzzes afterwards, check nearby panels, filters and cables; silicone isolation is a targeted remedy, not a guarantee of a silent system.
FAQ
Will these mounts make a loud fan silent?
Not necessarily. They are intended to reduce vibration transferred from a fan to the case. Air rushing through a restrictive grille, a damaged bearing or a fan running at high speed can remain audible. Identify the source first and maintain enough airflow for your components instead of assuming a mounting kit will solve every noise problem.
Which kit fits a slim closed-corner fan?
Noctua specifies the NA-SAV3 and NA-SAV4 for closed-corner fans of 10, 14, 15, 20 or 25 mm thickness, using the appropriate numbered position. Verify the exact fan and available hole access against Noctua's guidance. The NA-SAV2 is aimed at standard open-flange frames and is not the safer assumption for this job.
How many mounts do I need for one PC?
Allow four mounts for each fan if all four corners are secured. The 20-piece NA-SAV2 pack therefore covers up to five fans; the 16-piece NA-SAV3 and NA-SAV4 packs cover up to four each. Count existing fans and any planned additions, and leave room for spares if you expect to move the fans frequently.
