Silverstone makes two models of 120x25mm fans with the three-wire tail and a rheostat controller. They push between 103 CFM and 108 CFM, depending on the model.
The ThermalTake Blue LED 120x25mm fan is capable of at least 80 CFM -- but check again -- it might be in the 90's. It seems to be about as noisy as the Silverstone, and both are really pretty quiet at the high-end considering other options. I think their maximum ratings are in the 40 to 44 dBA range. There are also some Sunon 120x25mm fans capable of spinning up to around 3,000 rpm, with similar noise profile. I think the Sunon pushes something like 90 to 95 CFM.
The noise emanating from these fans is a very subdued -- tolerable -- bearing whine -- and only at the high-end. Air turbulence is going to plague any high-CFM fan, more or less, and can be mitigated with sound-deadening or thoughtful deployment choices. For the slight bearing whine, you might mitigate it substantially by putting a little Teflon grease on the bearing and re-sealing the adhesive bearing cover.
If noise and fan-life-expectancy are important considerations, then two large fans running at lower rpms are better than one. You can connect twin fans in a parallel circuit and run them off the same controller or PSU plug.
