Going to buy a Ninja Scythe for my Opteron 165 and am looking for 120mm Fan, but not sure which one I would go for. Interested in one that is not too noisy (probably not much of a problem with the 120mm), but moves a good amount of air and will keep this cool. Any suggestions? I used to have the Delta 80mm from back in the day, so I can put up with some noise if needed. I'm not sure they even make a 120mm as loud as that whiney noisemaker.
