There is an insanely loud Delta as high as 190... mine is an "ultra high speed" panaflo at 114.7.... yiffygriffy's medium speed panaflo is 88.5... so that should give you an idea

I would say that about 90cfm is good for a 120mm. At least, that's about average for a good one. Like Setite said, you can get them as high as 200cfm, but they are louder than he\\\\. It's all about balance between performance and noise, which is a personal thing.

For 120mm fans, usually between 80-120 for one that has a good noise to CFM ratio. Or you could just go for 375CFM at 200mm with 45dB? I saw one of those for $19 in a computer surplus store.
