I don’t know the air velocity of the built-in fan. But if the Noctua is the same diameter, and its CFM is equal to or greater than that of the stock fan, its air velocity will also be equal or greater.Noctua NF-A8 is the same diameter as the stock fan, but it is taller. I can't find air velocity specifications for the stock fan or noctua.
What is the built-in fan air velocity ?
