Those cases are rumored to have 95% sound reduction : http://tinyurl.com/hebw . Do you think is true ? And the price is great too : 125.00 $. Should I buy it ?

What kind of metal? Steel or Alum?

Honestly I have no idea. But how does this matter anything, I mean the only advantage of aluminum is weight…

No aluminum resonates/vibrates with the internal moving parts - much more so than steel - steel is much quieter.

Aluminum is in vogue due to weight and (as some report) the false notion that the case acts as a heat sink.

I'm told a steel case with good air flow is quieter than a lighter aluminum.

That would be correct, steel is stiffer than aluminum so it reduces the flex that amplifies resonance. Of course they could simply add ridges to either steel or aluminum to reduce resonance further.

Quiet PC's are becoming all the rage nowadays, and a lot of sites are offering so-called "silent" cases. But they are really just average cases with a bit of sound-deadening material attached to the inside of them. It would be quite easy to purchase some of this sound-deadening material separately and attach it to the inside of whatever case you want. Directron has a page dedicated to silencing materials:

<A HREF="http://www.directron.com/isolation.html" target="_new">http://www.directron.com/isolation.html</A>

Lots of good ideas there, but I am sure if you look around at your local hardware store or better yet, a custom car-stereo store, you can find the exact same stuff, and maybe a bit cheaper. Of course they won't have pre-cut gaskets to fit your PSU and whatnot, but those would be very simple to make on your own.

Manually building and moding a silent case is nice, however not everyone has the time or the will to do it. After all for the average user moding a case often means spending a lot of time on the case only to end up with an unsatisfying/ugly result... In this case buying a new case and starting again is often the only option. Furthermore I doubt your average user will be able to mod by himself a case with 95% noise reduction... Finally if you buy all the sound-deadening by yourself it may very well cost you more than the ST-11 case (125$), especially since some case ( *cough*Lian-Li*cough* ) cost more than 125$ to begin with.

As such the ST-11 case looks very attractive, if the 95% noise reduction is truth then it sure beats the LIAN-LI ALUMINUM PC-6070 LOW NOISE which has a mere 10% noise reduction.

I would be very weary of heat issues. As soon as you start sealing in the noise, you seal in the heat as well. Insulation is a bad idea.

Not if you still have normal airflow... the case itselve does nothing in heat transportation, that is something the aluminium case makers want us to beleive.

well it's sort of relative. With enough air flow the case is no longer an issue. Examples:
with 5+ fans, case probably dissipates 5% of heat, whereas with NO fans your case is more like 50% of your heat dissipation.

But I suppose if the case is sillent you could just install an insane amount of fans, but for this case I would recommend atleast 2 outakes and an intake. And note that this case only supports 3 fans.

Nope... even with only the PSU fan on (old 486 systems) or with the PSU and CPU fan on (Pentium 1/2/3 systems, although P3 can get so hot casefans are needed) the small airflow is the heat transporter. Now the modern CPU put out so much heat case fans are always needed to get nice OC'able temps.
Also cases are almost always painted... and paint is a great heat isolator. Trust me: aluminium case do not improve cooling ability... the only advantage is that they're lighter.

Look at the insulation. You can't tell be with no fans that stuff isn't going to affect the cpu temp at all. I'm dead seriouse, once you get the temp inside the case 5-10 degrees above abmient temperature your case is going to want to dissipate some heat. Except that insulation isn't going to allow that. With a couple fans, there isn't a problem. All I'm saying is that without fans even a PII wouldn't like that case.
And I'm not talking about aluminum, I'm talking about any metal barrier between the room air and the case air.

I have an all-aluminum (brushed, unpainted) CoolerMaster ATC-210 sitting right here. The aluminum panels of this case do get noticably warm compared to the ambient room temperature, so they are in fact dissipating some heat. However the difference between the panel temp and the ambient temp is hardly enough to seriously claim that the panels are a key factor in the cooling characteristics of the case. The problem is that air simply is not a good conductor of heat. In fact, it is considered an insulator. So whatever heat the panels absorb from the inside air is going to be extremely miniscule compared to the heat that is being put off by the heatsinks, because the air inside the case is acting like a blanket between the heatsink and the case panels. For proof, simply touch the outside of your case, then touch your CPU heatsink. After you're done cussing from the fresh blister your CPU heatsink has left on your finger, I think you'll agree that it is quite a bit hotter than the panels of the case. Adding a bit more insulation to the inside of the case is not going to make a lick of difference to how well it cools, as long as it is not restricting airflow.

Very very true. That is the exact point I was making, but with NO airflow you're simply asking for trouble, on pretty much any case. But this case would be much worse. I know I'm kinda spazing over nothing, but you know I figured that this dude should take that into consideration.
So if you buy this case just make sure you install 2-3 case fans or even the biggest baddest cpu air cooler isn't going to be able to keep up with even the lowliest of stock fans with a case fan sidekick.

Now if you want my advice. I've been installing and repairing competition car stereos for about 6 years now (I have two 15" subwoofers myself) and I know a thing or two about sound dampening. Go down to your local hardware store and by some linoleum. In particular the linoleum tiles that come with the peal and stick backs. Those work wonders, just stick them on any metal case surface. Try and get a fairly cheap (and therfore soft) type, the hardened type don't give as much vibration dampening.

Well there's my (hmmm 2 * 3) 6 cents worth.

I can't for the life of me figure out why anybody would build a system without any airflow. Are you contemplating no case fans - just the CPU fan?

No single fan in the system as the PSU fan also causes a small air flow inside the case... in other words PCs that don't exist.

Yes, but the amount of heat transferred by the case is so very small compared to the heat transfered by the airflow inside a case (even a case with only a PSU fan have aiflow).

I have isolated both sites of my case and I didn't notice any temp increase with only 2 casefans (of which one was inside the PSU)... is that enough proof or do you want more?

I notice the advert says <b>UP TO</b> 95% sound adsorption.

If you whack a high speed delta or tornado in that case its still gonna be LOUD.

I guess the insulation will ehlp with background hard drive noise and such though.

Better IMHO just to get a decent case with quiet casefans for pretty much the same effect.

As for aluminium doing cooling, the top right above the PSU gets warm, as does the side at the back of the mobo tray, but thats about it.
Proly only accounts for half a percentage point of cooling, unless i stick on some external heatsinks.

But yeah the 'increased cooling ability' of aluminium cases isn't worht the price... even steel cases get hot around the PSU.

Well, Guillaume, mon ami. Your plea has not fallen into deaf ears. I, being the the wonderful and handsome man that my aquaintances worship, have decided to actually shell out $160 bucks to purchase the ST-11 you were wondering about and test it for you. I Have ordered it today and I will diligently relay my findings and conclusions to you as soon as I get it.

Please, please, no applause is needed.

Awesome! thanks for the linoleum tip, I may have to give that a try. I have noticed that the foam rubber being marketed toward PC enthusiasts is very ridiculously priced. Even better to recieve a tip like this from someone in the audio reproduction industry.

Ah yes, much easier to cut. Simply line the inside of your case with the tread sections, it will be quiet!

Yes, and you can easily make an Amiga fanless, but neither have any relavence to performance oriented PC users.

And what good does going fanless do when your fans are so quiet you can't hear them? All I can hear running on my PC is the hard drive!

You are aware that a K6-III 450 performs better than a C3-1000? Not too many of us want to downgrade that far.

My desk is fanless too, and all it does is sit there and hold my computer off the floor.

It's in the Sandra charts, which tend to be fairly accurate for typical systems.

In fact there was no K6-III 800, 450 was as high as they went (heard of a 500, heard they decided not to release it).
