they do 2 types of the SP fans one is the high performance

Airflow 62.74 CFM
Static Pressure 3.1 mm/H20
Sound Level 35 dBA
Speed 2350 RPM


And the normal quiet edition

Airflow 37.85 CFM
Static Pressure 1.29 mm/H20
Sound Level 23 dBA
Speed 1450 RPM
Power Draw 0.08 A


am i correct in thinking the high performance is the same at 1450rpm but then can reach higher speeds and airflow when ramped up?
