Difference between SP120 Performance and Quiet Edition

I was looking for a new fans on Corsair's website for my H100i. I checked for Quiet Edition and Performance Edition but on specifications it shows that they are the same?



Quiet Edition: LINK



Performance Edition: LINK



Can somebody tell me what is the difference? I plan to connect the fans to H80i controller and then set RPM to 900. Will quiet edition be more quiet than performance if both are on 900 RPM?



Thanks
