soundproofing case with styrafoam?

i have a lot of styrafoam lying around the house so i'm thinking of putting some inside of my computer's side panel. Would this actually make my comp sound quieter or is styrafoam crap?
 
Yes, it will make it absolutely silent - because it will fry the computer and it wont work anymore

Styrofoam has a lot of static electricity in it, and that is HORRIBLE for computer parts

You would be better off lining it with currogated cardboard (sp?) or just dropping the $15 or whatever and buying DynaMat
 
dynamat is pretty much a piece of rubber that absorbs sounds, mostly used in card. Or you can use the spray on stuff, works pretty well and is pretty cheap
 
As long as you're not putting the styrofoam in extremely close proximity to anything sensitive then the static electricity poses no risk. Besides, it will only be able to build up a charge from the air moving across it, and I wouldn't be surprised if that failed to create any significant charge. Also, electricity tends to follow the path of least resistance, since the case is grounded, any static electricity arcs are likely to travel to the metal case.

You could also paint the styrofoam with chrome paint (assuming like most types it is conductive), or if you're lazy, just aluminum tape/foil. That would completely eliminate any static electricity concerns.
 
I am very surprised that nobody here has pointed out the biggest problem with using styrofoam to kill sound. Styrofoam is an insulator that retains temperature.......a good example is cheap throw away party coolers. Not only do they keep your drinks cold on ice, but if you were to put hot food in the cooler along with a hot pack, it would retain the heat as well. PC's as we all know tend to generate a lot of heat. I think this methode of sound proofing your PC, will turn it into an easy bake oven. If the static electricity does not kill the PC, the heat will.

That would be correct, if the primary cooling method would be the conduction of heat through the case's structure.
 
lol enough with the soundproofing threads you guys. Less fans = less noise.

I dunno. I tend to think that a single Tornado fan at full speed is worse than an entire case constructed out of fans designed with the user's comfort in mind.

Yea but there's a lot people who OC their systems and need as much air cooling as possible while at the same time keeping a low noise system. Less fans means less cooling too .Also some people don't want a high maintenance water-cooled system.

Then they can build a low maintenance watercooling system. The main source of sound leakage out of a case is the holes. The main source of sound in a case(for most people) is fans. Fans + holes = loud case. No amount of soundproofing the sides of the case is going to prevent sound from coming out of the fan holes.

It is much easier to start out with quiet fans in the first place than it is to have loud fans and try to dampen the sound. Get big fans and run them slow. That way you can still have a good amount of airflow but the fan won't be spinning really fast and making a lot of noise.

Oh yeah, and the second loudest source of noise is hard drives. A good way to cut down on hard drive noise is to put rubber washers between the drive and the case. The washers will significantly cut down the vibrations that are transferred to the case.
