I've been wanting to place foam in my case to hear the results for awhile now. So finally I decided to. Before:
After:
$10 worth of foam plus $5 can of spray adhesive (I barely used any) + $40 NZXT Source 210 = "silent case"
I will say that the case is quieter (ever so slightly). I will eventually get a CM 212+/EVO as my TX3 is the loudest part atm. Also I was a tad lazy in cable management because this was the second time this week that I took my computer completely apart.
Temps: (before) CPU: 65c GPU: 65c
Temps: (after) CPU: 69c GPU: 67c
Truthfully I was expecting a higher rise in temps.

what is the point of foam for noise reduction when you have huge holes in the top and sides of your case for fans

Huge holes < all directions. Also without a lot of fans temps be crazy and cpu/gpu fan spins faster therefore more noise.
Also I was looking for [any] noise reduction, not noise cancellation.

You know what would solve both the noise and heat issues, but would take a lot more work?
Mineral oil immersion. Get one very quiet pump, or put the pump on the outside end of the heat exchange radiator.
Of course... you do have to remove all fans, open space, and have someplace with strong floors. And it might take some plumbing skills.
(Not as good as liquid chlorofluorocarbon immersion, but CFCs are not easy or fun to use.)

My computer isn't worth going to custom liquid (which is what I would do).
|
Or you could just have a passively cooled system. :D

My DIY watercooling loop works very nicely. Dead silent, and cool at all times. I did have to get a f***ing massive corsair case for enough space to house the radiator though... But it's not so hard or expensive to do!

Um. I might be being stupid. But surely foaming your case like this is just going to add insulation making it hotter and therefore more in need of cooling.

That was my first thought.
Buying a good quality case and large slow fans has made the biggest difference to mine. Obviously much more expensive than foaming your case up though.
It's a shame you can't measure the decibels coming out of it for a proper before and after.

It makes it slightly warmer, but you can adjust your fan curves so you just hit temperature equilibrium a few degrees hotter. What it does nicely is damp out GPU fan noise and harddrive seek noise, which, imho, is by far the hardest source of noise to remove in a computer if you dont have the space/aren't willing to go for a full suspension (even that doesn't solve everything). Sound insulation is of pretty minor concern if one is running stock coolers on their CPU/GPU with loud case fans/PSUs/etc, but it can make a pretty big difference once you've covered the basics. If you want a quiet computer, it's rather pointless, but if you want a silent computer, it's rather key.

GPU is more of a problem than CPU for gamers.
I dont think you can buy watercooled GPUs easily, so you would have to do it yourself and void any warranty.
|
I came into this thread thinking you were going to fill the entire air volume inside the case with foam. Disappointed!
|
put on some earplugs/headphones and your computer will be quieter. thats what i do

CLC's are terrible. First off they have weak pumps. Second and most importantly they use Ethylene Glycol which is in every way inferior to water. Last off they have jet engines of fans just to be competitive cooling wise.
From frosty tech:

The problem with watercooling is that you need a water pump which itself makes noise. With the current spate of bigass tower coolers and 120mm fans on everything + PWM, air cooling isn't much louder than liquid anymore.
I barely hear my computer and I'm not even running 120mm case fans, just a super old Thermalright Ultra Extreme with a slow 120 and an arctic accelero 2 on my 5870. Having an SSD helps too I guess. Going liquid would probably bring down temps but I doubt it would make it any quieter.

I foamed my airsoft gun with cotton balls, and made a wooden silencer. Worked perfectly. Sadly your case has huge fan holes
Pretty neat idea anyway!
