Anyone ever used Dynamat sound deadening material in a PC Case?

[spliffstar69]

Im trying to get the PC noise down a bit and was thinking about putting in some dynamat,
anyone here ever tried that before.

Let me know thanks

found a few links on it here i think im gonig to give it a try

found some info here

If you are trying to silence a PC, the recommended approach is to only try deadening/absorbing the sound after all other solutions. For the amount of $, you get much better results with quieter PSU, CPU HSF, Case Fans, HDD's. Isolation mounting the fans and HDD's can also work wonders. What is the system now? What fans at what voltages?

B-Quiet Brown Bread is cheaper than dynamat and offers the same sound deadening. I have this in my car and the stuff really works when it comes to sound deadening. I ordered a 35 sq ft roll and it wieghed about 10lbs. I don't think your case would be that muchheavier if you do decide to use it.

Dynamat won't do much at all. It is a vibration dampener not a sound absorbtion material. For the same price you can get some proper stuff from quietpc.com. I just ordered in the Power Snooze kit myself. It even comes with 2 dynamat type sheets for the side panels. The acoustipack is even better, but it's a little more expensive.

It does work great for a car, but most of the pc noise is escaping out of vent holes (unlike road noise that vibrates through the metal underbody). To prevent this, the sound needs to be absorbed before it can leave the case. The best way to go is a layer of Dynamat and then a layer of sound absorbtion material. This is what the AcoustiPack kit does. It has both concepts built into one material.

Its mainly the the HDD noise im trying to reduse there is 5 HDD in this system the fans are doing there thing cooling the system 4 total with a very low amount of noise,
but when the drives are running its very loud.


I will look into that power snooze

you can get harddrive cases, silent drive i think, but it'll cost you like 60 bux per drive

most solutions that work for silencing are either costly or work intensive, a little dynamat isn't going to help much i bet. i've lined a case with 1/2" accoutstic skinned foam before and it only worked a little, sound escapes from fan holes etc. some people build external boxes with baffles inside lined with accoustic foam, so that sound basically has to bounce a couple times and get absorbed. put these on your fan intakes/exhausts and well you've got an ugly case

don't buy the silentcase thing from japan. your drive will be hot and it's too expensive.

take a look at this.

look on the same site to find a DIY version. since you've got 5 drives, it'll be worth it.

that looks cool

I'd think twice about putting dynamat on your hard drives. Seems like it would be a great insulator, not just for sound, but for heat. I'd hate to see them get quiet in two ways - first because the noise dampening, and later on because they died... May or may not actually happen, just a thought.

 

[0roo0roo]

yea in the end...all the time/money is waste, better to buy a quiet drive in the first place.

Yes, better to have bought a silent drive to begin with as 0roo0roo said. Now that Seagate makes 200GB drives...

Failing that, next best thing is a new case. As mrzed said, DON'T waste your money on sound dampening/deadening materials until all other approaches have been tried. For a new case, look for one that uses 120mm fans and comes with rubber grommets for the hard drive mounts. Doesn't seem like much but there will be a noticeable audible difference. Only drawback is that the drives will run warmer (hence, using a case with 120mm fans). Antec makes a few like this:

http://www.newegg.com/app/ViewProductDesc.asp?description=11-129-122&catalog=7&manufactory=BROWSE&depa=1
$82
Nice heavy guage steel (very heavy case) with five 3½" drive bays with rubber grommets, rear 120mm fan and a front mount for an optional 120mm fan. Good airflow design, nice color and a 350W Smart Power power supply. I have an OEM version of this case and love it.

Other Antec cases with rubber grommets and 120mm fan mounts are the Super LANBoy (aluminum), P160 (Performance Plus 1, aluminum) and the Sonata (steel with Truepower 380W). All these are more expensive and only have 4 hard drive bays.

If you really want quiet, pick up two Intel gigabit NICs and a nice long Cat5e crossover cable, build yourself a budget server, heave as many drives into it as possible, and put it somewhere out of earshot. Your actual desktop system can have one nice, quiet drive in it. Map network drives to the HDDs over the network, there you go.

And to answer the question: I tried some Dynamat-clone stuff. No dice. What works is to go after the source of the noise, like several wise people have said.

I've lined the walls and floor of my case with carpet padding. Sure, there's a risk for higher temps., but, I've not had any issues with heat and have been running it in the configuration for well over a year.

Keep in mind that sound deadening material works by absorbing the energy of sound and converting it to heat energy.

The entire goal is to keep the heat away from your parts and by sound deadening, you are introducing more heat to your computer.

is there such a thing as non-conductive jelly ?
