Sound deadening

[lonewolf5460]

My friends has some spare dyno mat good idea to use on my antec threehundred two love the case a lot even though I wish I got a corsair case for dual rad support. Only problem even though I have my h80i fans at 900 rpm and it handles my 8320 @ max load and the fans are all set to min there is a slight vibration from my case thats killing it from being purely silent. Any recommendations before I slap on dynomat which is car sound deadening stuff on my case any other recommendations?

Sounds dampening mainly prevent echo or sound bouncing around in the case, usually it's best to invest in quieter components as sound dampening can only do so much.

Be honest it is quiet its just a tinny type of case if I hold my side panels the noise stops. If I take out my tradition hard drives its dead quiet like totally inaudible. So I may just get a nas for back up or spring for dynomat its really thick stuff with aluminum backing and really sticky if it can reduce in car noise 20db on a strait pipe s2000 I figure it can stiffen up my side panels and stop the sound. I was just curious if there is more of a specific computer based solution,

For HDD's you can try mounting them on rubber or foam mounts to help prevent it from transferring vibrations. With the side panels if they are vibrating you can use some tape to take out some of that slop or slight movement of the panel. The sound dampening does help to a degree if your wanting to try to minimize it at much as possible.

Yah I was planing on some thin foam where the panels slot on and some grommets or something for the actual drives they are tool less so I am still trying to figure it out. Surprisingly moving the hard drives to an lower bay seems to have fixed the issue I cant hear anything. I may just try the dyno mat as well because it may help when the mechanical drives are under load.

There are two ways to dampen sound:
1) Reduce the ways sound can exit the case. Sound travels best through air so this means reducing airflow which is... not good. For this reason I do not suggest any cases designed to be "silent".
2) Isolate the noise inside the case. Such as coating it with materials that dampen the metal on metal/hard plastic vibrations. This is alright as Luke's video shows you need to do a stupid amount of cramming crap in a case to impact it negatively in any way.

You can use as much isolating material as you want as long as you don't get it inside any components (fire risk) or block any of your fans. But generally the best way to isolate noise would be the following steps:
1) Watercooling like the corsair h100i for your cpu and gpu.
2) Silent fans like the "be quiet!" series (you can also replace the fans on your radiators easily. Just make sure they match the size like 140mm or 120mm and screw them in.) You can also add temperature sensors to your case and set your fan profile to "silent" which lets the temps get a little higher before turning them on and tries to run them at lower speeds.
3) Keep your overclocks reasonable. If your comp is always maxed out and running hot it is going to make noise.
4) "Eco Mode" on your psu and an efficient power rating. The higher the power rating the more power goes to the components and the less is lost which becomes heat forcing your fans to turn on. Eco mode keeps your psu fan from always running so it will only turn on when the psu needs it. Getting a psu with a lot more headroom will also mean it can handle a bigger power load so even when your computer is doing heavy work it will be less likely to need the fan. Evga makes some excellent 1000w platinum rated psus with eco mode and Be Quiet! also has a line of psus but I've never used them.

tl;dr try replacing your fans with the "Be Quiet!" fans, make sure your psu is not one that has the fan always running, try using thermal sensors and adjusting your profile so the fans run less often, and only as a last resort put any kind of sound dampening material inside your case. (And if you do... do it smartly without blocking fans or causing fire risks)
