Anti-vibration Soft Silicone Fan Gaskets

Quick Fitting Steps
Fit the fan gasket onto the outside of the fan housing (it will stay on the fan)
Position the fan and gasket together against the inside of the case, so that the four mounting holes in the fan and gasket line up to the mounting holes in the case side
Locate the four silicone washers and screws, and fit the washers against the case side, each secured by a screw
Tighten the screws enough to very slightly compress the silicone rubber. Do not over-tighten.
Please Note: Do not use these gaskets in very high temperature locations inside a PC/Server such as attached to a CPU cooler or GPU heat sinks! These gaskets are designed to be used against case side p

Fitting Recommendations
 
These gaskets are suitable for the vast majority of case designs and fan combinations, as they fit standard fan mounting holes. Slightly lengthened (12mm thread) fan mounting screws are supplied with the fan gaskets and washers. These gaskets can be used with standard PC cooling fans, and not just with AcoustiFan quiet case fans.

The Shore hardness is measured with an apparatus known as a Durometer and consequently is also known as 'Durometer hardness'. The hardness value is determined by the penetration of the Durometer indenter foot into the sample. A 'softer' material will have a lower Shore value than a 'harder' material.

Shore Hardness (using either the Shore A or Shore D scale), is the preferred method for rubbers/elastomers. The Shore A scale is used for 'softer' materials like silicone rubbers, while the Shore D scale is used for 'harder' materials.

Help to 'seal' the small gap between the fan and the casing/enclosure wall. This improves the efficiency of the fan, by reducing airflow 'feedback' and therefore air pressure losses, and
Help to absorb the vibration that otherwise would be transmitted from the fan into the case chassis and case housing.
What is Shore Hardness?
The hardness testing of plastics and rubbers is most commonly measured by the Shore (Durometer) test or Rockwell hardness test. Both methods measure the resistance of plastics toward indentation and provide an empirical hardness value.

AFG120B - for 120mm case fans (any fan thickness)
Advantages
Silicone fan gaskets are truly the 'ultimate in fan noise reduction', because they perform two important tasks:

Effective? - Yes, these are simply the most effective yet!
Why are these silicone fan gaskets especially effective? Because we have not held back on the silicone thickness and the silicone material softness. All gaskets are 2.5mm thick (not just 1mm like alternatives), and Shore A 25 (a great deal softer than others we have tested). We are confident that these two factors make these gaskets more effective than any other models available.

Anti-vibration Soft Silicone Fan Gaskets
(AFG60B, AFG70B, AFG80B, AFG92B & AFG120B)
(B=Black, C=Clear) Retail Pack (1 Gasket) & OEM Pack (32 Gaskets)
These ultra-soft fan gaskets are designed to reduce the vibration from PC and server case cooling fans, and maintain a seal between the case side and the fan housing. Each retail pack contains an anti-vibration fan gasket with 4 silicone washers and mounting screws. We believe they are the thickest and most effective available anywhere!
