You specify airflow in m³/h, how can I convert it to CFM?
In accordance with the International System of Units (SI system), Noctua specifies volumetric flow rate (airflow) using the SI unit of cubic metres per hour (m³/h).
You can also find airflow rates in cubic feet per minute (CFM) in the Specifications tab on our product pages. When browsing our fans on the overview page, hover over the airflow value in m³/h to display it in CFM.
The SI unit m³/h can easily be converted to cubic feet per minute (CFM): 1 m³/h equals ~0.589 CFM and 1 CFM equals ~1.699 m³/h.
Some values and their conversions are presented in the table below.
