Noctua 120mm NF-S12B ULN 120mm Fan 700/500RPM Review

This is the quietest fan for the amount of cfm it puts out. That's not saying that its output is small. On the contrary, other fans I've tried have less output at this noise level. I've replaced every fan in all of my computers with these. You will hear your hdd tick before you hear the fan.
