Silicone Anti-vibration Fan Gasket for 70mm Case Fan

Silicone Anti-vibration Fan Gasket for 70mm Case Fan

Brand: AcoustiFan

Details:

A retail pack of 1 soft silicone anti-vibration fan gasket with 4 silicone washers and mounting screws. These silicone gaskets are designed to reduce the vibration from PC and server case cooling fans.

The following models are available:

AFG60B - Black, for 60mm case fans
AFG70B - Black, for 70mm case fans
AFG80C - Clear/Translucent, for 80mm case fans
AFG80B - Black, for 80mm case fans
AFG92B - Black, for 92mm case fans
AFG120C - Clear/Translucent, for 120mm case fans
AFG120B - Black, for 120mm case fans

Advantages

Silicone fan gaskets are truly the ultimate in fan noise reduction, because they perform two important tasks:

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, and
Help to absorb the vibration that otherwise would be transmitted from the fan into the case chassis and case housing.

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)

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. Note: Do not use these gaskets in very high temperature locations inside a PC/Server such as attached to CPU or GPU heat sinks!

Technical Specifications

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.

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.

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.

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.

Installation:

Fitting Directions

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.

Silicone Anti-vibration Fan Gasket for 70mm Case Fan is a great Quiet Computer Fans and Quiet Computer PC Parts by AcoustiFan. Enjoy the great selection of Quiet Computer Fans and Quiet Computer PC Parts

Browse our selection of quiet computer fans and quiet pc fans. We offer truly silent computer fans and silent pc fans. Case fans, CPU fans, motherboard, and video card cooling fans share the same design considerations as Power Supplies and you pretty much get what you pay for. Buy quiet computer fans and quiet pc fans. Browse our large selection of silent computer fans and silent PC fans. Silent fans and quiet fans are really a great way to replace your loud fan and eliminate fan noise. You can also decrease case fan noise with vibration isolation. Even rubber grommets placed over the mounting bolts, between the fan frame and the surface to which the fan mounts, will help reduce the transfer of vibrations to areas of the case that can resonate sympathetically and acoustically amplify the noise. PC noise can be drastically reduced by this. You could also cut your own gaskets out of sound dampening materials and place them between the fan and mounting area for your own custom solution. Recently, Acousti Products has introduced some fairly inexpensive, yet effective, silicone gel fan mounting grommets and similar fan gaskets. Acoustic absorbing materials for quieting PCs can be placed around the airflow path inside the case to absorb noise. Just be careful not to impede the airflow itself. Standard 80mm case fans usually come in one or two wiring configurations, and each has its own type of connector. A four-pin Molex connector delivers 12V DC. It doesn’t inherently accommodate speed control which doesn’t give you as much control over performance of the fan and output noise. The three-wire type of fan allows feedback from the fan so the user can see the fan speed, and/or an alarm can sound if the fan fails so you will have notification before your computer fries. If your three-pin fan speed isn’t controlled by the motherboard, inexpensive fan speed controls let you limit the fan speed to a lower RPM to drop unwanted noise levels quite a bit while making sure enough airflow to dissipate heat still exists.

A fan’s spec sheet will specify air throughput in CFM or cubic feet per minute. The larger the better, a 120mm fan rotating at a low speed will usually move more air than a smaller fan running at a higher RPM. The AcoustiFan 120mm fans from Acousti Products are literally inaudible while providing excellent air circulation. Most people think aluminum cases are better at getting rid of heat; however, a thick steel case is better for stopping sound transmission from within the computer. Well-fitted case parts can help reduce noise that escapes through cracks. Some people leave the side of their PC off, thinking it provides more ventilation. However, many cases need to be fully assembled for the air flow design to work effectively. Always consider getting a full tower to allow for better ventilation. A larger internal space means that less air needs to go through the system per minute. Always think efficient air flow and convection is good when installing internal components. If you can leave some air space between multiple hard drives, do so.

The most common case fan sizes are: 80mm, 92mm and 120mm. There are dozens of models with different speeds, airflows and noise ratings. (CPU heat sink fans are generally 60mm, or more recently, 80mm in size.) In general, larger fans generate greater airflow (measured in CFM) and operate at slower speeds (RPM) than their little brothers. Due to lower fan blade speeds, larger fans typically generate less noise and at a lower pitch. Larger fans typically produce less air velocity and less static pressure than smaller fans do. This can be a disadvantage when trying to mount a large fan to a small heat sink using an adapter. Most fan adapters are aerodynamically very inefficient. The larger fans just can’t push their rated airflow through a restricting adapter and therefore will usually perform less effectively than a smaller, high velocity fan with a similar airflow rating.

It is a good strategy to use multiple, low RPM fans. These fans do not move as much air as higher RPM fans do, so we need to use more of them. If you have the room and prefer to use 92mm or 120mm fans, that’s fine; just use the quiet larger models.

The fans we offer are the best at offering good air flow with minimal noise. Try to keep the airflow (air-in vs. air-out) reasonably balanced. If you plan to use filters on the inlet fans (a good idea) then compensate for reduced airflow by having more total airflow going into the case than coming out.
