** Why are Fan Mounts Necessary?** Vibration from fan motors can travel into a PC case & become amplified when a fan is fitted tightly. This unwanted vibrational noise is an issue if you wish to build a very quiet or virtually silent PC. These mounts have been designed from the drawing-board specifically to tackle fan-induced vibrational noise! Acousti Ultra-Soft Fan Mounts are a no-vibration alternative to standard fan screws or hard plastic push pins. To prevent the transmission of vibrations from a motor (such as a fan motor), the vibrating part needs to be decoupled (or disengaged) from the case, & the vibrations need to be damped, that is, attenuated. Acousti Products have selected an ultra-soft silicone polymer that effectively decouples the fan & also attenuates unwanted vibration. Both the shape & materials have been designed together to give a widely compatible fan mount. These mounts are made from an ultra-soft silicone polymer because it is softer & more chemically stable than cheaper alternatives like rubber or EPDM. Ultra-soft silicone is non-toxic, more chemically stable, & can also tolerate higher temperatures
- so it is a superior material for this application. * These Acousti Ultra-Soft Fan Mounts are the OEM packs of 100 mounts in bulk (enough for 25 fans) for OEM & system builders.* **AFM02B Fan Mount Design.** The fan mount has been designed with smoothed corners to prevent the propagation of cracks when stretched. When in position, the fan is held 1.25mm away from the case side
- this is just enough to allow free movement of the fan & effectively absorb vibrations, but not too much to cause excessive air pressure loss around the fan. ** Compatibility** Please note that this product is only compatible with flange type fans. This is because flange type fans (shown below) do not have a tunnel connecting the mounting holes like Rib type fans. Flange type design is the most popular type of fan moulding use
