ive done a few experiments with trying to deaden the low frequency sounds of a baracuda IV and a pump... ive tried spongy type computer foam, polystyrene and some stuff which didnt work...

polystyrene does fairly well at decoupling vibration, but does really well at not letting sound pass through...

i plan to glue foam to my HDD waterblock, then glue polystyrene to that, and seal it up nicely. maybe ill make a polystyrene box lined with foam and just put the HDD/pump inside.
then if theres still noise coming from the enclosure, i reckon glueing foam to the polystyrene box, then putting another layer of polystyrene over that.

basically, the HDD/pump are watercooled, vibration decoupled with foam, then the noise is contained using polystyrene. silicone tubing will be used.

ive also got some camping mattress style foam to try out. its about 1cm thick, rubbery, very dense and you can squish it a bit.

any comments?
