i got a lian li 70 case and just put some crazy new high RPM heatsink and case fan in it and its driving my roomate crazy lol. So i need to do some emergincy sound proofing for as little as possible, i was thinking of taking cardboard sheets and adhearing them to the pannels to reducevibratino cuz the cardboard is free i cant really aford the foam or alumimum stuff so im looking for inventive ways to muffle this noise oppen to all ideas or links to sites or forums of folks doing stuff like this so nothing is to crazy~!

thanks for your help!

go to lowes or home depot, get some ceiling tiles, and use those.

also, hope to high heaven nobody sees the innards of your comp... they'll die of laughter if they do. ceiling tiles a pretty computer do not make.
 
bingo, lol. they have rather good sound dampening abilities... but they like to crumble a tad bit, and they will look tremendously ghetto craptacular in a comp.
 
You might try some adhesive foam sheets from a craft store first. You can usually get several square feet of the stuff for just a few dollars.
 
spray on bedliner (like the stuff on trucks...rhino I think is real popular) from wal-mart works real well for dampening vibrations. Tape off the parts of your case that you don't want it on (like between the cross-railing and the door...kind of a tight spot there on some cases) and give it a couple good thick coats., when it dries, you can then add some of the foam sheets to it to absorb the "airborn" noise. Then you've got the vibration and white noise muffled. Did that to my old case (for the foam, I grabbed the stuff that was used in the Compaq boxes that they ship replacement parts...like a miniature egg-crate design) and it made a very noticeable difference. And all for about $5 total.

Interesting... and cheap! Might consider that. :)

If you do try it, do it on a a piece of metal that you don't care about first to see if it will work ok for you. The actual roll-on stuff you can get from places like K-Mart is MUCH better...but also much more expensive (my friend did his truck bed with it and the kit was around $140). But with the cheap spray on stuff, I really mean thick coats. a few thin coats won't do it, but this is what the spare piece of metal is for. Try to get one about the same thickness and material as your case, that way you can judge how much it dampens the vibrations and if it'd be worth it to do your case like that...because it's hard as hell to reverse ;)
 
The roofing material is called "Peel N Seal"

It is essentially Dynamat (except Peel n Seal has a silvery finish, to match metal), alot of car audio enthusiasts use it in place of Dynamat since it is A LOT cheaper and possesses similar qualities and performance. Careful though, the adhesive it uses is VERY good, it is hard to remove a piece once it has been applied (you don't even need a heatgun); you'll need a razor, box cutter , or REALLY good/strong scissors to cut the stuff.

They sell it at Lowes in the roofing/shingles isle (not sure about Home Depot). Its designated purpose is for metal roof patching. They sell it in rolls, I believe a 6' x 6" (that's 6 ft by 6 inch) roll costs around $12. Considering Dynamat cost exponentially more, its a good deal and does well for all my applications.
 
Well its not that cheap 20$ a role but dinamat or somthing like that looks better then tiles don't you think. And egg fome works great.

Sounds interesting, might have to try that..
 
I wonder what impact (if any) any of these methods will have on ambient case temps.
 
that spray on bedliner is kinda heavy is it not?
ive got a nice and loud lian li pc-71 that im thinking of sound-reducing, but its already pretty heavy with all the goodies in it.

i think id like to try something less permament, like maybe the roofing material
 
why shouldn't you, 0 dba = teh winnar


Just wondering, does anyone think the guy in the newegg banner used photoshop to make his teeth whiter? :rolleyes:

It can be if you put it on thick enough. That's why I mentioned using another piece of metal the same material and thickness...because there comes a point where you'll get diminishing returns on putting it on thicker. I think that whole process added about 8-10lbs to my Supermicro case (thick steel...damn thing was already heavy...but now it didn't vibrate and rattle :D ). I used 4 good coats of the stuff on both door panels, the motherboard tray, top, and bottom of the case (inside of course).

that peel n' seal is good stuff from what I've heard too...haven't tried that yet though.

and that guy in the newegg ad does have some crazy white teeth! dang! while they were touching up his teeth in PS, they should have gotten rid of his uneven 5 o'clock shadow :p
(maybe it's the lighting though...)
 
putting it in a closet will negate that expensive heatsink, since putting it in a confined space will recirculate the hot air. putting cardboard will thermally insulate the case WAY too well and acoustically insulate it almost none; and the components will roast and maybe even start a nice fire with all that flammable material :eek: . the peel and seel is the best thing because it transfers SOME heat and isolates a lot of the noise. i use dynamat in my cases. the egg crate foam is good but only in places that dont get hot, like not BEHIND the mobo tray. get a quiet heatsink/fan is the best thing you could do. Vantec and Zalman make some that are nearly silent as does Coolermaster, and they will keep temps close to where the loud ones do, if not lower because they're well designed and ALSO quiet. ;)
