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).
We have designed a unique set of 4 self-adhesive soft silicone feet (UK Reg Design Applied) of varying softness for different case weights. These case feet are designed to decouple a PC case from the floor or substrate by absorbing vibrational energy, and therefore helping to minimise noise generation caused by vibrations.
A little extreme? Well, yes, perhaps: but even with very quietest PCs it is vibration that becomes the most significant culprit/contributor to noise generation. So we have developed these case feet to try and minimise vibrations in our pursuit of 'ultimate noise reduction'. We hope you enjoy the difference - check out the feedback & reviews from customers below!
Antivibration 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.
|Suitable Applications for Anti-Vibration Feet||Max.
(Pack of 4)
|Light weight PC & SFF PC cases, HTPC cases, vibrating HiFi units, TV and home cable set top boxes, small speaker cabinets, inkjet printers etc.||8Kg
(2.0Kg per foot)
|ACF3007-15B||Shore A 15°|
|Medium-to-light weight PCs, solid SFF cases, heavy HTPC cases, larger inkjet printers and laser printers, heavier HiFi units (such as power amps), speaker cabinets etc.||14Kg
(3.5Kg per foot)
|ACF3007-20B||Shore A 20°|
|Medium-to-heavy weight PC cases (suitable for the majority of PCs), larger Macs (like the G5), large laser printers, large speaker cabinets etc.||22Kg
(5.5Kg per foot)
|ACF3007-25B||Shore A 25°|
|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.||30Kg

|ACF3007-30B||Shore A 30°|
|*The max load is the 'maximum optimal load' where 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.|
Walibe.Com review AcoustiFeet ACF3007-25C
"The case feet are so often over looked in any case but this should be high on your list ... the case feet make a huge different overall and should be considered an essential purchase... Acousti Products have demonstrated why they are considered to be the best manufacture of silencing equipment for your PC... " Awarded 5 Paws Down! - Walibe.Com Excellence. [full review]
Phoronix.com review AcoustiFeet ACF 3007-25B
"Overall, these silicone feet installed great, didn't fall off the bottom of the case, and a decrease in noise was noted.
... Although we were a bit skeptical at first, we were dumbfounded with how much of an improvement both of the items had made on our deafening computers. Costing only a few dollars from our friends at QuietPC, we see no reason not to recommend such wonderful products.
Pros: Efficiently dampened computer vibrations, Easy to install. Cons: None!" Rating: 8/10. [full review]
Extreme Reviews on AcoustiFeet
"When installed on the very noisy Pentium 3 system, they seemed to work a treat. The system sits on carpet flooring and the vibrations were greatly diminished. The sound of vibrations could no longer be heard on the lower story and you could only actually feel the vibrations if you were within 2-4cm of the case feet. Testing the case on a wooden desktop, there could only be felt some very tiny vibrations, definitely something you wouldn't notice on a day-to-day basis.
...These feet are great at dampening vibrations." Overall: 80%[full review]
[AcoustiFeet (Model ACF 3007-25B)] "Well, I was skeptical, but I must say... YES!!!! :-) The low frequency tone from my 10k rpm harddisk didn't disappear but almost did! This was a GREAT improvement! Amazing that something so simple can have such a great effect!
I can't really say if any other sounds were reduced because that tone was so dominant before. The loudest noise now is the turbulent air flow from the fans (and the rumble from harddisk seeks). The tone is very much reduced where I sit in front of my desk. But if I go behind my desk, at the rear of my PC - it's still there (coming out from the back of the PC). I am unsure if it has reduced the noise from the rear of the PC or not. I don't fully understand the effect the feet have had, because:
1) my computer case is really heavy,
2) the noise did sound like it was coming from the case and not the desk or anything, and
3) my desk is an old style rather heavy one, and also has 30Kg CRT standing on it. Also, the case still vibrates noticeably - you can feel it if you put your fingertips to it."
Our Response: we think that what has happened in this case (no pun intended - sorry about that) is that the soft feet have isolated the PC case somewhat, and the vibration previously being transmitted into the desk has been significantly reduced - which explains the reduction in the dominant 'hum' (which is a hard-to-place, non-directional background noise). Once you fix one noise source others become suddenly more noticeable - perhaps this accounts for the noise at the rear of the PC!! Noise coming from inside the PC breaking out of an air gap or hole (like a fan grill) may become more noticeable if generalised background 'hum' is reduced.
Soft feet will serve to absorb (by damping) a proportion of the case vibrational energy previously transmitted into the desk/floor. A PC case is likely to vibrate 'to the touch' after fitting silicone feet, because the soft feet have isolated the case from transmitting so much vibrational energy into the desk or floor, and the case is also likely to vibrate more freely on it's own. Kjell Rilbe, Sweden
"They work exactly as described, there used to be a slight vibration on the desk where my machine is sitting during a lot of disk activity or accessing the cd-rom that is completely gone, there is absolutely no vibration on the desk anymore... I'm very pleased!" Tavis Ormandy, UK
"Nice product, I have been using it for some while. The PC seems to float on the floor, much vibration removed." Ivan, Slovak Republic
"Make a good alternative to feet for hi-fi equipment - also less expensive than hi-fi dedicated feet." Ian, United Kingdom
"I use these on enclosures - absorbs vibrations nicely." Chester, USA
"It's surprising how much vibration is knocked out by replacing the feet of any case." Scott, USA
As one user from the USA has put it "No case should be without a good pair of shoes!"
