Sound dampening foam is ideally the last step you want to take to silencing your PC.

If your fans are loud, Then consider buying quieter ones.

no it's the ammount i have running not just one noisy fan

I doubt the number of fans makes it louder.

24 seem to

Ah.

Rubber washers where the fans are held?

yeah it's basically the fans on my radiators making a racket :S but they are only 1200 rpm each

Order of business is first to minimize amount of noise being created and blocking direct noise escape paths.
Acoustic materials can only dampen amount of reverberation and sound trying to get out through it, neither of which work if sound can leak out directly.

that's what i was hoping wouldn't happen, is there anything i can do?

Which case have you got? How are your fans attached?

it's a completly modified coolermaster haf 932 (when i mean completley you probally wouldn't recognise it) fans are attached to radiators and the metal (with rubber dampners) to the back of part of my mod

Is it where your rad attaches to the case? Vibrations get everywhere.

nope, it doesn't sound like vibrations i'm still building it up but it just sounds like the fans could be quiter :S

And you think foam may help? - removing half the fans would be a better option and most likely will has zero effect on your temps.
It might even be cooler with less, depending on how they are arranged.

Don't mean to be rude, but either you've been given really bad advice or it's a fan company sponsered build

may i ask why you think it's bad advide~? :S
it will be for a 5 gpu setup and a real heafty oc on the cpu - mostfet + other chipsets and ram

so are you saying you have push pull on all three - sounds like bad advice unless you have a twin i7 server board with quad sli.

yes 3 in push pull you got it - it's not twin i7 but will be single i9 and hopefully 5 gpus assuming i have the pci lanes

well i'm having it setup (hypotetically speaking) assuming things come out which i need, but my haf i have 13 3.5" bays now to

Wish I had that kind of cash.

i9 + mobo - rad
2x gpus - rad
3x gpus - rad

Makes sence I guess - not your normal pc then

well, i'm componenting it up hopefully next summer (when i hopefully will have the money) it may only set out with 2-3 gt 300s though dependent on the finance but in the end it shoudl have them all

Pre build, you might also want to look at using PA or RX rads - 3x 800rmp fans will give excelent results on these - I run my PA120.3 (cpu/NB/GPU) without any fans and my system runs OC'ed 24/7 at load - It's no gaming monster but it still shows how good the PA's are.

Intel I7 920 CPU
ASUS P6T6 WS Revolution Motherboard
6 Gig DDR3 Memory
6 12inch PCIE flexible extenders.
6 9800GX2 dual GPU Video Cards.
1 Custom WU Milking Machine Frame

Folding farm - only reason i can see for a 5 card setup

beautiful setup, how may pci lanes does the core i7 have?
