Here and there we come across the opinion that it is advisable to test fans in real life conditions, which we can easily refute. At the same time, we understand that a layman can best identify with the differences in component temperatures that arise precisely due to different fan airflows. To help you see the correlations of such tests with results from “unnatural” environments, here’s something we remembered.
Results: Very low noise level (31,5 dBA)

Why is there a missing value sometimes? Some fans cannot be slowed down sufficiently to make their speed correspond to the specified noise level. The minimum speeds are then above this level, thus the associated measurement cannot be made. This is why you won’t be able to find the result in the chart.
Small error, the fans on the Thermalright T-Rad2 are NF-A9x14, not NF-A9.
Yes, thanks! Fixed. 🙂
