we manufacture Anti-vibration mounts, which are essentially silicone sleeves for fan screws. However, in order to use them properly, the mounting holes on the case must be enlarged, which not everyone is willing to do. The new mounts do not require this modification, as they do not rely on screws at all. Instead, they are designed to take the place of screws. The new mounts are quite similar to another product that is popular in the silencing community. This product has been available for years as a way to soft-mount fans.
