A suggestion I heard...
This is a suggestion I got from my Grandfather in regards to quieting a computer case. He is a self-taught mechanical engineer, and it sounded a bit hokie to me until I thought about it.
Basically his suggestion was to place rubber emasculator bands as "washers" between any two things to be screwed together. In particular between the case and the fan to dampen the vibration of the fan against the case. It isn't perfect because the screw still transmits some, but you don't have the fan vibrating directly against the case.
Here is a link to them that includes a picture. They are about the size of cheerios, and run for about $1.00 per hundred of them at feed stores.

Before you ask, they are used to castrate animals.

Wow, that's creative. How soft are those bands? Softer than a regular rubber washer. As soft as a foam earplug? I bet you could do something like this:Dorzak wrote:Basically his suggestion was to place rubber emasculator bands as "washers" between any two things to be screwed together.

Bear with this poor ascii art side profile. Imagine the red stuff as a small diameter bolt with a nut (diameter is narrow enough to not touch any part of mounting holes). The |___| is the fan frame. The 2 green things are those bands (or could be soft foam). The grey vertical line is the case.
It might not be too practical, but I was just brainstorming anyway....

$1.35 should be for 100 of them. I know the feed store I used to work in (circa 1991) charged $0.50 for 100 of them. They are the size of a cheerio, softer than a washer but harder than a regular rubberband. They are designed to cut off blood flow the the part being removed so that it drops off. To put them on for that purpose requires a special tool that expands them.Mark Larson wrote:On that site, is it $ 1.35 shipped for a 100pack of those? Or is that per band?
I used that site becasue it was the first image of them I found. You can find them a lot of places by searching for "Emasculating Band" or "Castrating Band". However, chances are unless you live in the middle of NYC or LA, there is probably a place within 10-15 miles of your house that sells them. Just look in the phone book for "Feed Store" or "Animal Supplies." They are a one size fits all type of thing, so the same size is used for dogs, sheep, and cattle.

I was gonna post that, but thanks for doing it for me. The very thought of using something on a fan used to castrate animals creeps me out in some way...Rusty075 wrote:I've seen lots of inventive cross-polination of technologies here: Lawn mower intakes used as filters, Pringles cans used as ducts, Car radiators used for cooling, etc, etc......
But Castration Bands!?! for that you deserve some kind of award.
Nicely done
They are thicker and softer than a normal washer. Therefore, I believe they should dampen vibration better.Rusty075 wrote:I've seen lots of inventive cross-polination of technologies here: Lawn mower intakes used as filters, Pringles cans used as ducts, Car radiators used for cooling, etc, etc......

Of course if a bunch of people start ordering them for delivery to urban areas, I wonder what the retailers of them are going to think?
EDIT1: Before anybody asks, I am going to try them myself when I build my wife's computer. The computer will not be totally silent, but will be a little quieter than some. I have been thinking of place besides just fans I could use them, on a trial basis.
Hahaha, well I just finished my silent computer, and one of the tricks I used was using ear plugs cut in half to use as screws between the fan and the computer case itself. Works great, the foams are stiff enough so the fan doesn't sag but soft enough to allow some flexibility so that the vibrations from the fan hardly seems to transfer over to the case. If anyone cares for pictures let me know and I'll go take some.

The ones I got were the cheapest ones at the local drug store. If you could get better quality ones with better compression, it might make the installation easier. For me, when you cut the earplugs into halves, it expands too quickly to thread through the holes so I had to force them through.

I'm sure some of you have seen these but for anyone else, rubber grommets, the best solution:
http://www.frozencpu.com/cgi-bin/frozencpu/scr-10.html
At $0.60 a pop ($2.40 / fan) these are pricey, but a quick search could yield some better prices, somewhat hard though considering most people want you to buy 1000+ pieces. If anyone finds a seller, do tell.

Ummm...I think he was making a joke.Ralf Hutter wrote:Hmmm, that's a good point. I guess it might be a good idea to Loc-tite everything if you're going to use those bands.ahrbruz wrote: HOLY COW!
I really enjoy the cross-discipline suggestions. However, won't using these in your computer cause all the nuts to drop off over time?
hehe

Are these the same grommets available at from the PC shops?

Looks like a good deal
