My personal solution to fan noise is to run ordinary fans at slow speed,
which makes them essentially silent, and just use more of them.

To slow them down I either run them off the 5V supply instead of 12V, or
stick a resistor in series with them - something between 150 and 220 ohms
usually does the trick. Which approach I use for any given fan has to be
determined by playing with the fan concerned - some prefer to be run off the
lower voltage, and some prefer the resistor - "prefer" meaning "start by
themselves without needing the flick of a finger". The only one I don't do
this to is the CPU fan - I leave that with the full unhindered 12V.

It doesn't work with hard drives though :-)
