Noctua specifies airflow in m³/h. Here's those values converted to CFM

Airflow: 53 m³/h (31.19 CFM)
Airflow with L.N.A.: 39 m³/h (22.95 CFM)
Airflow with U.L.N.A.: 26 m³/h (15.3 CFM)

Hope this helps.

Hi Jerry,

I'm guessing you are looking at replacing the case fan (not the CPU fan). If that is the case, the original fan appears to be a 92mm x 92mm x 25mm size.
So this Noctua fan is the wrong size, but there are plenty of 92mm fan options. The easiest way to make sure you are buying the correct size is just take out the fan to be replaced and measure the side length directly.

Hope that helped!
