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 soft silicone anti-vibration PC case feet designed to absorb vibrations from PC cases and similar vibrating enclosures.
 Anti-vibration replacement low-profile 'AcoustiFeet' - retail packaging |  Image showing a black foot on the underside of a computer case. |
Acousti Products have designed a unique pack of four self-adhesive silicone feet available in four 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!

Multiple Applications
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:
- Very Soft (Shore A 15°) for lightweight PC and SFF PC cases, HTPC cases, vibrating HiFi units, TV and home cable set top boxes, small speaker cabinets, inkjet printers etc.
- 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.
- Medium (Shore A 25°) for medium-to-heavyweight PC cases (suitable for the majority of PCs), larger Macs (like the G5), large laser printers, large 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.

These unassuming little stick on feet have cured virtually all of my case hum that I was experiencing. Cheap, easy to apply and do exactly what they were designed to do. Don't expect to drag your case around afterwards though, being silicone they tend to grab the surface that they are sat on.

I recently bought these to reduce the vibration from my Sony Media PC - it was sitting on a wooden shelf and the vibration was starting to get on my nerves, even though it is designed to run quietly. I put these on and the PC now runs in absolute silence. These are superb - do the job and then some. Fully recommended.

I bought these for a "humming" PVR not really expecting them to make much of a difference, but they removed 100% of the vibration hum being transferred to my cabinet instantly.

I had my doubts when ordering these as I've had 'acousti' brand fans before and didn't rate them much at all. However the drone from my HTPC (an asrock 330) when I loaded a slightly off-balance DVD was driving me crazy (I should point out that this wasn't the norm). Hallelujah! These feet have answered my prayers, any vibrations which may have previously been transmitted through to the shelf, if present, are now inaudible. Also of note is how grippy these little fellas are, which ensures that my little box doesn't go sliding across the shelf whenever I jab the power button. Overall highly recommended.

Of course these would only benefit you if your machine suffers from the dreaded HUM - HUM - HUM. This used to transmit itself through my desk into the whole room, replace the rock hard feet on your case and the vibration should go. I opted for these 'Soft up to 14kg', my case isn't exactly lightweight, with a decent power supply, 2 HD's 2 Optical drives and a big CPU fan. Even if the end total is nearly a fiver they are well worth it.

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!
