Sound Dampening Foam

[mister_s]

I've seen that Be Quiet has sound dampening foam in their cases, and I would like to get what they use, or at least something similar for my case, but they don't seem to sell it.

 

Anyone got any recommendations?

I've seen dynamat used and I have personally used this stuff: https://www.homedepot.com/p/E-O-12-in-x-15-ft-Self-Stick-Foam-Foil-Duct-Insulation-FV516/100028603 for damping sheet metal enclosures.  I would assume care must be taken in how much and where to apply the material or you may overly thermally insulate your case.

 

For the the sheet metal damping I have done the self adhesive foam is applied only to the center of large panels and a 1 - 2 inch perimeter is left blank.  The stuff isn't very expensive, so you can always try it out and experiment.

 

Be sure to monitor thermals in addition to sound!

Thanks for the suggestions, I'll probably give the duct insulation a try, I think I have some lying around the house actually

Dynamat is more for heat insulation than sound insulation. For computer use, I recommend Acoustipak 7mm self adhesive foam. I used this in my last desktop computer (and have it in the one I'm building) and can tell you from experience this stuff works.

Also you should find sound insulation bitumen mat in a car audio store if you're in a pinch

Automotive sound insulation works for automotive noise. Computer noise is different.

You're not going to get much of a noticeable decrease in noise levels.  Probably not worth blowing the money on.  Maybe try turning down the fan curves first.

Actually, if you use a foam designed for computers (such as the one I linked) and apply it correctly, it can make a significant difference.
