Sound Deadening Stuff?

[YMAN]

Hello,
I was a bit curious on how I could quiet up a case.
I was thinking something on the lines of a sound
deadening material like foam to put in the case.
(side pannels, bottom, top, parts ot the front ect.)
I have heard of this stuff before but not payed any
attention to it. How much does this stuff cost? is it
worth it, has anyone tried it?

Any other Ideas are also welcomed.
I do not wish to change fans to "Quiet" ones,
nor attempt a watercooling setup.
(Reliablility & Damage Possiblilities)

If there are any low noise fans however that also
produce alot of CFM, I would like to know about them.
(Note=Must be standard Pc fan size. Ex. 50mm, 80mm 96mm ect.)
I would also appreciate any pics that can help.

Thanks

I was also looking at another post about sound deadening
devices.

Sounds interesting!
If anyone can find such a device let me know.

It is called: Anti Noise Theory

Somebody said put powedered graphite in the fan to lower the noice, but that might not be to smart.

 

[YMAN]

I think Powdered Graphite is some type of "dry" lubricant.
but isn't it conductive?

I think I will pass on this idea?

 

[BigJohn]

3in1 oil then maybe?

Dynamat works well line your case sides in that it does help!!

Well, the most ideal way would be to put 1" of foam rubber between every single outside-touching surface and the inside of your computer.

But since you can't do that (Behind the motherboard, and by the 5.25" drives), you can use this product from Edmund Scientifics called Sorbothane. It's made for lessening impact force, but it should work marvelously for sound too.

Can I have some more information and maybe a site, pics.
Not to mention a place that sells it online? (The dynamat stuff)


I am also interested in this Sorbothane.
Has anyone tried it?
If someone has please let us know and I cannot stress more, I
love pictures!
Is this stuff conductive, it seems like it may have an oil or somthing that would be conductive?

You see how it is shiney:

One thing I LOVE the MOST is PICTURES!
I must admit this stuff is tempting even if it doesn't work!

Also the Dynamat stuff...You are leaving me in the dark
What is it?
Were can I buy it? (Online)
Do you have any pics?
Please tell us some more details!


Oups, I seem to have posted twice?
I think something is wrong with the OC servers?
At first the one above did not show up?

I bought a sheet or Sorbothane a few years back for a motorized scooter project I was undergoing.

It looks shiney because it's rubber. And as such, is completely nonconductive. It's thin enough that you don't need to have any of it touching any of your components anyway, even between the motherboard tray and case panel, you'd still be able to squeeze 3 sheets of the stuff in there.

It looks and feels like any old rubber sheet, but if you took a hard object and dropped in onto the Sorbothane, you see why it costs so much. Something that might bounce 5 times bounces once then comes to a stop.

It's great stuff, albeit extremely expensive.

Edit: Replying to your red-text edit, I don't know about Dynamat. It seems to be widely used, but I don't know ANYTHING else about it. I bet you could get more info if you posted a thread called "What is Dynamat?".

Dynamat is a trade name for sound dampening sheets used by the car audio industry, an alternative is Punchmat by Rockford Fosgate they work by altering the resonance frequency of the pannel and can be obtained from all good car audio dealers.
Another product to consider is the 'lead' sheeting used on roofing, this has also been used by the car audio industry as a cheap way to cut vehicle noise.
Sound dampening in the car audio industry is heading towards using composite sprays such as 'noize killer' as this does not have the weight problem associated with matting

 

[YMAN]

Does noise killer spray work?
Atleat would it help in a pc?

Were can I buy Dynamat and find more info on it?

That audio frequency thing, how does it work? Can it
be purchased online, if so where?
Is it very effective?
I herd of this before, but I don't know much about it.

Hey, I just found some nifty stuff, you may want to check it out:

http://www.sounddomain.com/sku/CAEVB5

It's only $15.95, and coveres almost 5 square feet!

Or, you may want to go with a spray variety:

[YMAN]

I like the spray kind.
Do you think it will be a good choice?
I mean, I dont have dual 14 inch subwoofers!
I just would have a ton of fan/SCSI hard drive noise...

I honestly don't care how loud my computer is, I would just turn up my game volume if it got too high (Which it hasn't--yet).

But some people are very particular about how loud they let their computers get. If you've got $20 extra bones to spend, and you can't deal with a loud computer, by all means, buy some. If you're like me, and don't give a hoo-hah, then save your money for a neon light or a case fan. =)
