Although many PC components create noise in themselves, this can be made much worse when components are installed into a PC case, and their noise can become amplified by vibration of the metal onto which the component is mounted. These soft silicone general-purpose washers seek to reduce or eliminate this vibration effect, which often manifests itself as a deep, annoying rumbling sound
Each 1" Acousti-Slab is 610mm (24in) by 1220mm (48in) and are sold individually. The panels are plain faced which means the panels have good even thickness which results in there is more foam per panel compared to profiled tiles of the same thickness. This extra amount of foam results in improved absorption and overall better results. The Acousti-Slab is designed to allow you to make up your own fabric covered acoustic panels instead of using Rockwool or Mineral Wool which can be irritating to use due to escaping fibres. With acoustic foam there are no escaping fibres and so is perfectly safe to use. One panel covers an area of 0.72 m2 (8 ft2). The acoustic panels are available in dark grey only. The foam has a density of 32kg/m3 and a hardness of 180 Newton. The NRC of the 1" Acousti-Slab Acoustic Panel is 0.55. We only use professional grade open cell acoustic foam. We specialize and are dedicated in selling only acoustic foam products. You will not find us selling other products such as upholstery foam or packaging foam, foams which are not suitable for acoustic applications. All of our products meet the requirements of schedule 1, part 1 the Furniture and Furnishings (fire) (safety) Regulations 1988 (amended 1989). This Furniture and Furnishings is a more stringent test then the FMVSS302 which other companies advertise. The FMVSS302 is an automotive fire classification and products which only conform to this classification are not suitable for use in domestic or commercial applications. Our products are totally safe and suitable for use in both domestic and commercial applications. PLEASE NOTE: Items sold by Efoam are not genuine Advanced Acoustics products and are not sold with our permission.
Acousti's new multi-layered composition has a low reflection upper surface (opposite the noise source) with a high density plastic acoustic barrier layer either 'suspended' in the centre of the acoustic foam layer, or at the base of the composite. Both 2- and 3-layer composites offer excellent sound energy attenuation because multi-layer composites are more effective than single layer soundproofing materials.AcoustiPack composite materials are dense but still flexible, and come with a strong self-adhesive backing. The soundproofing materials come with instructions and can easily be cut to shape before fitting. Unlike other noise reduction materials, the 'pick-and-place' self-adhesive allows the installer to have a second attempt at positioning the materials if they make a mistake first time round!The acoustic materials, including the adhesives, have been carefully selected and thoroughly tested to meet stringent UL94 international flammability standards. In this respect they lead the market in quality and safety.
•Help to absorb the vibration that otherwise would be transmitted from the fan into the case chassis and case housing.
•Help to 'seal' the small gap between the fan and the casing/enclosure wall. This improves the efficiency of the fan, by reducing feedback airflow and therefore air pressure losses.
Other advantages include:
•Compatible with virtually all case cooling fans
•Supplied with screws and silicone washers
•Quick and very easy to fit (these gaskets 'hold onto' the fan whilst fitting them due to a small lip in the gasket design)
•Operating Temperature: (-)20 - (+)70°C
•Softness: Shore A 40 +/-5
•Material: Translucent Silicon Rubber
•Gasket Thickness: 2.5mm
•Recommended Compression: 5% of height
See also: AFM03B Easy-Fit Fan Mounts Why are Fan Mounts Necessary? Vibration from fan motors can travel into a PC case and 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, and the vibrations need to be damped, that is, attenuated. Acousti Products have selected an ultra-soft silicone polymer that effectively decouples the fan and also attenuates unwanted vibration. Both the shape and 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 and more chemically stable than cheaper alternatives like rubber or EPDM. Ultra-soft silicone is non-toxic, more chemically stable, and can also tolerate higher temperatures - so it is a superior material for this application. AFM02B - Acousti Ultra-Soft Fan Mounts are available in both Retail Packs of 8 mounts (shown), and packs of 100 mounts in bulk (enough for 25 fans) for OEM and system builders. 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 used in PCs & servers. For rib-type fans, we recommend gaskets rather than fan mounts, which will give equally good performance.

AcoustiFan DustPROOF - Premium Quality Quiet 80mm Multi-Purpose Cooling Fan The fan motor for the DustPROOF range of virtually silent fans is extremely quiet. The AcoustiFan DustPROOF series use the highest quality double-ball bearings available for reliability, use-anywhere inside a PC for extra long life expectancy (upgrade your PC and take these fans with you!). One of the unique features of these PC fans is that the motor has been completely sealed from the outside environment. This prevents dust entering the motor and also reduces the amount of noise perceived to be coming from the bearings within the motor. Each DustPROOF quiet fan is also supplied with a unique 3-speed fan cable which offers maximum flexibility (3-pin or 4-pin Molex power connectors), along with the ability to select a fan speed suitable for your PC and noise sensitivity. The black connector will run your fan at full speed (12V), the blue connector will run the fan at medium speed (7.5V), and the white connector will run it at minimum speed (5V). However, if you opt for the white connector (minimum fan speed), be certain to design the airflow through your PC system carefully and monitor system and component temperatures. Acousti have even included four handy cable ties with each DustPROOF fan! The DustPROOF quiet fans also incorporate an Auto Start safety feature. This feature is built into the fan's PCB and automatically restarts the fan after the release of any obstacle which has prevented the blades from spinning.
