AcoustiFeet Vibration-absorbing Low Profile Silicone Feet
A simple and economic solution to combat unwanted vibrational noise! - throw away your plastic feet and apply a set of four self-adhesive soft silicone case feet! A great deal of PC case feet are solid plastic, or (at best) very hard rubber and therefore do a good job of transmitting unwanted vibrations from inside a PC via the chassis/case into the desk, floor or shelf on which the system sits. In this situation, where the case is in direct contact with the substrate, the PC can generate annoying noise elsewhere (secondary noise).
ACF3007 - Four silicone anti-vibration PC case feet designed to absorb vibrations from PC cases and similar vibrating enclosures.
Acousti Products have designed a unique pack of four self-adhesive silicone feet available in different softnesses (to support different weights). These feet are designed to decouple a PC case from the floor or other hard resting surface by absorbing vibrational energy, and therefore helping to minimise noise generation caused by vibrations.
A little extreme? Well, yes, perhaps: but even with very quiet PCs it is vibration that becomes the most significant culprit/contributor to noise generation. So these case feet have been developed to try and minimise vibrations in the pursuit of 'ultimate noise reduction'. We hope you enjoy the difference!

Anti-vibration case feet are not just limited to combating PC noise and for vibration control in their application - they may be useful for Inkjet and Laser Printers, HiFi Separates, TVs, Small Form Factor PCs, Home Theatre PCs, and any number of appliances and enclosures that would benefit from vibration adsorption and reduction. Speaker cabinets may also be a useful application for these feet - helping to isolate the speaker cabinet from the surface on which it sits. These feet are low-profile (7mm high), so they won't necessarily be seen, and they are non-marking. The rounded edge is designed specifically to dampen vibration transmission in multiple planes. Different foot softnesses will suit different PC & server weights - we suggest the following as a rough guide:
- Soft (Shore A 20°) for medium-to-lightweight PCs, solid SFF cases, heavy HTPC cases, larger inkjet printers and laser printers, heavier HiFi units (such as power amps), speaker cabinets etc.
- Firm (Shore A 30°) for seriously heavy PCs and tower server cases - heavier PCs with multiple HDDs, tower-style case servers, other applications like noisy photocopiers and office equipment etc.

|Softness||Shore A 30° (firm)|
|Optimal load per foot||7.5 kg|
|Max total optimal load (4 feet)||30 kg *|
|Foot dimensions||30mm diameter x 7mm high|
|Pack weight||28 g|
|Material description||Non-marking silicone elastomer [UL94-HB]|
|Colour / odour||Matt black / odourless|
|Operating temperature range||-20°C ~ 70°C|
|Self-adhesive properties||3M Y-9448HK / Non-woven double-sided acrylic|
|REACH and RoHS Compliant||Yes (EU Directive 2002/95/EC)|
- *The optimal load is the heaviest weight at which compression still occurs in the feet. The feet can carry higher loads, but they become over-compressed and suffer a reduced vibration-absorbing capacity if overloaded.
I actually can't believe it!
I really can't believe what a difference these AcoustiFeet made to my server. I have an HP Proliant ML110 with a RAID array sitting in my office. Its very quiet except that the vibration from the box can be felt and heard throughout the house as a barley audible hum which I was finding annoying especially at night. I was sceptical about these feet but I thought for the price I probably wouldn't have
lost much. These AcoustiFeet are amazing! Not only did they arrive promptly they were simplicity itself to fit and the vibration from the box has completely disappeared. Thank You!
I was starting to get a little annoyed with the noise my computer cabinet was making whilst my PC was on. A humming noise, but not constant, was up and down (noise level). So after a little search using google, I found these feet advertised and ordered them straight away. As they are cheap I wasn't that bothered if they didn't work, but I have been totally surprised. The noise has completely gone :)
I own an Antec 1200 gaming case which is pretty loaded with gear, and very heavy so got these firm feet which as I said before, worked perfectly!!!!!
These feet are HIGHLY recommended by me. I'd give 10 out of 10 for performance, 10 out of 10 for QuietPc's price and speed of delivery.
Thanks very much for your swift despatch.
Vibrating TV speaker problem solved
I have a 37" LG TV which has an "invisible speaker" system. The cabinet of the TV is supposed to increase the sweet spot. Many though have reported across various forums that their speakers vibrate on certain tones, certainly enough to be a pain, (a claim conveniently denied by LG).
I didn't want to go opening the back, fitting padding etc. and all that malarkey and otherwise it's a great set so I stumbled upon the Acoustifeet via a post on AVForums.
I called their technical support who advised me to get the firm variety (they're still quite soft however to touch). They arrived the very next day, I needed 7 of them for the base of my TV stand and the self-adhesive was easy to fit. Turned on the TV and the difference was remarkable and I'm not easily pleased. First class, I can even have the bass turned up a bit now without a problem
where before I had tweaked settings that lacked the oomph! that's provided by the Cinema mode. Thanks very much!
