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!"
