Results: Static pressure w/o obstacles
In this test, we’ll take a look at Noctua’s anticipated first representative and how it ranks next to other fans. We’ll start from the bottom with the most affordable one from this Austrian company. It should be noted that Noctua views this class of fans slightly differently than other brands, and has the base perched very high. However, there is one BUT, which is rather insignificant, but still “lifted some people out of their chairs”.
Results: Static pressure w/o obstacles
Explanatory note: We measure the static pressure without obstacles in two different situations – with laminarized and with turbulent intake. The results in this section reflect the first case. That is, the air intake to the rotor is laminarized by the guidance tunnel. In this setup, the fan has a larger volume of air available and the achieved static pressure values are higher. This is the optimum environment in which to measure fan parameters correctly.

Buying the Asus ROG Strix XF120 reading your review! It’s 20-50% better in nearly every category/setup vs the Noctua! Love my high-end Noctuas but for the cheaper side to case cool my new i9 14900k OC’d well over 350W on my custom loop, I need all the fan performance I can get. ASUS ftw again! Plus I have mainly ROG in it as we speak. 🙂
