Depending upon how intense you want to get with this, you can mount a big heat
sink to the CPU and then use a larger fan to blow the same volume of air over
the larger surface. Noise induced by airflow follows an inverse-cube rule,
so reducing the air velocity by half will give you an *eightfold* decrease in
noise. It's an old trick used in studio design -- that why you typically see
oversized air ducts in such facilities.
Cheers!
