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.

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.

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

Sorry did you say 24 fans at 1200rmp :rolleyes:
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

Your noise is a result of the turbulance caused by your fans interacting with each other, there is no way you need 24 fans in or on a haf 932.

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
