20-pack 43 mm anti-vibration fan mounts

This 20-pack supplies silicone rubber mounting screws sized for 43 mm case fans. The soft material dampens vibration between the fan frame and the chassis, lowering operational noise. Builders assembling or upgrading compact cooling setups will find the quantity sufficient for multiple fans. The black finish blends with standard PC hardware.

Check fan hole spacing and frame thickness

Verify that your 43 mm fans use standard mounting-hole spacing compatible with a universal rubber-screw design. Confirm the frame thickness allows the screw shank to pass through and seat securely without bottoming out. Ensure the case mounting points accept the same pitch so the flexible pins engage cleanly. No tools are required for installation.

Silicone rubber replaces metal screws

Each mount substitutes a metal fixing screw, eliminating direct metal-to-metal contact that transmits resonance. The high-temperature-resistant silicone remains flexible over extended service life, maintaining shock absorption. Quick press-fit insertion speeds up fan swaps during maintenance or testing. The pack provides enough mounts for several fans or spare replacements.

Questions about this item

Does the 20-pack include any metal screws or only the 43 mm rubber mounts?

The pack contains twenty 43 mm black silicone rubber mounting screws and no metal screws.

When should I choose the 43 mm length over a shorter or longer variant?

Select the 43 mm version when the fan frame and case panel together measure roughly that thickness so the mounts seat without stretching or bottoming out.

How much vibration noise does the rubber material actually cut once the fans are running in a case?

The ultra-soft silicone absorbs fan vibration at the mounting points, lowering case resonance and audible hum compared with rigid metal screws.
