Carpeting cases....

[cookieman]

Hi!

I'd like to know if somebody else had modified it's case in order to make the sound of the fans more bearable. And how did it worked this far.

I had put a lot of carpet (I don't know how to call it) (2 weeks ago) in my full tower and the temps had gotten a little higher (+ 1-2C) but the sound is almoust entirely gone.
I only hear the PSU and I do not regret that I've done that. I bearly hear the beep at boot time
I suspect the airflow is worse now but my Duron 750@850 +.1v (L1 soldered ) is still in it's best shape.
Temps: 26C ambient, 32C motherboard, 48C CPU full load.

Abit KT7
Fop68 3800 RPM.
Maxtor 7200, 30Gb.
300 W PSU

Whats your experience ?

Cheers,

I wouldn't use carpet for one major reason, carpet is made with strands of cotton/polyester/plastic and is subject to falling apart. Those strands will eventually clog up fans and possibly short out components. I don't know the conductivity of carpet fiber though. Anyone know?

One reason why it might be neutral, carpet is now designed to be fire proof/resistant. But that could be bad because it will insulate the case and retain heat.

Just my 2c.

what about wrapping the outside in some nice carpet with some filters over the fans, just the sides, top and bottom that would make it silent.

Hi!
It's 5 mm thick, so it's not a normal carpet.
Until now all fans are ok, but I'm keeping mi eyes on them. 5 Fans so far: CPU, chipset, PSU +
an additional 80 mm Fan to exaust heat, 1 FAN to blow on the HDD.

And i see no sign of fibre on the components... I also now that the fibre of this carpet
is more thick that the dust, so dust is more dangeuros, isn' it?
I enjoy the silence and take a chance on this.
Cheers,

use carpet padding (HIGH QUALITY) on the inside and carpet on the outside.

set case in large box, fill, box w/cement, let harden. make sure cables are still accessable.

concrete vibrates...

 

[cookieman]

Carpeting was not my idea, I read that on the Net somewhere...
Maybe it's not a so good idea to try carpeting the outside because the sound must be stopped before it starts vibrating in the case and amplifies itself. If the case vibrates the sound will come out somewhere (PSU holes?) and you will notice only small sound reduction.
But I'm not stopping anyone to try that

Cheers,

with the (HIGH QUALITY) carpet padding on the inside and the carpeting on the outside the case SHOULD be almost if not completely silent.

Speeking about concrete, the case got pretty heavy now

Cheers,
Catch you up on monday, happy weekend to all of you.

I covered mine with a towel one night when the noise was getting to me. More than 5mm with the doubled over towel. Didn't block any fans in or out, but golly, the whole thing was warm the next morning. CPU was up some 8C.

But it was nice when it was quiet. Guess I don't have enough through-flow

Car audio stores have sound deadening material they install when putting in speakers in certain areas of cars. I use a brand called DYNAMAT its good its about 2mm thick and has an adhesive backing that sticks real good. I haven't noticed any temp increases with this material cause i put in certain areas on the case, inside/sidepanels,inside/backtop,inside/top,outside/front.
Only if u want to spend the money.

Put carpet on the outside and then u'll be a pimp

I made an organic case. Utilized a hemp base planting mesh that can hold a growing medium and planted grass and wildflowers
in it. I water it with a mister every morning and then use a FlowBee to cut it. Works pretty good. Needs a little time to fill in. Should be nice in about 2 months. Real quiet though and smells nice

Dynomat does nothing to reduce fan noise..Dynomat is made to stop a cars body panels from vibrating, not to absorb sound.

 

[kilmanjaro]

And why do a car's body panels vibrate??? Oh yeah, because of sound. Sorry, not meant to be a flame, but dynomat CAN be effectively used as a sound dampener.

Put Shag carpet on the outside and you'll be a pimp

 

[cyke138]

try this http://www.mmxpress.com/dynamat.html

 

[Dill]

no, you are wrong. Dynomat stops vibration, NOT SOUND!

Dynomat absorbs the 'movement' that causes vibration in the body panels be adding mass to the panel. More mass equals less vibration.

so not to flame you either, but thats incorrect.

Hahahahaha, that's pretty funny. I think you need to seriously rethink you logic on this one.


Hahaha, I'm still laughing. Got to PM this one to several people!

Here's a direct quote off their site about the applications of it. &quot;Whether it be in your automobile, COMPUTER, home appliances or architectural needs, Dynamic Control has the right product.&quot; The reason I think it works is because I've lined my case with it, and noticed a pretty substantial drop in noise. I know my logic earlier wasn't exactly right, nor was it supposed to be, but I was trying to make a point. They actually make applications for a computer case. But, a better way would be to get some thin studio foam and use it. I used dynamat 'cause it was REAL cheap and I didn't have anything to lose. Your results may vary.

cookieman....I carpeted in inside of my case with what sounds like the same material as you mentioned. It's more like an &quot;indoor-outdoor&quot; material. Very low/tight pile...I've used it for sound control in workstation cubes...bank lobby walls etc. I had mucho laying around the shop and thought I'd give it a try awhile back. Did nothing to my system temps and worked very well in dampening the sound in the case.

&quot;Badger Carpet&quot; makes this stuff and is available in many colors. If you guys have ever seen &quot;sissel&quot; which is a wallcovering like fabric. This is very much like that but thicker....still less than 1/4&quot; though. No loose fibre's either. It adds that little bit of &quot;mass&quot; to the sides and top...stopping those vibrations.

 

[UCBPride]

what kind of carpeting material did you use? and whaere can i purchase them

 

[UCBPride]

Which of these four kinds of Dynomat: Dynamat Original, Dynamat Extreme, Dynamat Super, Dynamat Premium, will serve my computer best?

use rubber...pad it up...rubber absorbs sound nicely...my 2¢
