Acustipack delux - Question

Post by Schroinx » Tue Jul 13, 2004 8:04 am

Some time ago I bought some Acustipac Deluxe, but first now I have the time to install it. I have tried to find information about this material is safe to put between the mobo and the mobo tray. Or to say it differently: Can this material conduct electrisity?

Any thoughts and experience with this will be much appreciated.

The foam is made from rubber, so it does not conduct

Another winner from google:

Looks like you should avoid fitting it so it directly contacts the motherboard

Thx for your replies.

Looks like they'd updated their site, since I passed by sometime in jan.

The material is nonconductive but should not be placed in direct contact with the components and cirtuitry. Well the components on the underside of the mobo mostly resistors and the like and the traces on the PCB is protected. So:

Anyone who actually tried with this stuff between mobo and case?

Since the manufacturer specifically recommends NOT, maybe you should be the first to try. :) :roll:

Neither is it recommended to change the heatsink on your gpu nor fiddle with the mobo. Things I have already done, together with many others here. Many things are not recommended, but we do them anyway. So I don't mind being the first. However if there is someone around who have tried it, then I might as well learn from his mistakes and succes, instead of repeating it myself. Or what do you think, mg1394?

I don't think the question should be "Has it been done?", but "Is it any use to do?"

The composite material from the acoustpack kit has three functions:
1. Absorbing and scattering airborne sound waves (by the foam top layer)
2. Blocking sound (by the heavy bottom layer)
3. Preventing resonance (by the heavy bottom layer)

Now lets see if it can fullfill these functions between the mobo and the mobo tray:
1. When it scooped up there, the airborne sound waves won't reach the foam. So exit function one.
2. The mobo tray is not the outside of the case. So blocking the sound from going where? Exit function two.
3. Now your mobo + mobo tray could be resonating with the CPU-fan. (Not very likely, if you have already silenced the CPU-fan.) But if you attach the acoustipack to the other side of the mobo tray, it is just as effective in preventing resonance.

In short: Why run the risk that the aucoustiproducts FAQ is right, if you won't benefit from the trial?
