I'm getting new fans for my radiator and I'm going for the Noctua Industrial fans. The NF-F12 Industrial 2000RPM is 29.7db but also has 3.94mm/h20, while the 3000RPM version is 43.5db, but has a 7.63mm/h20. Now I really want performance, BUT is 43.5db really loud? And if I were to run this fan at 2000RPM would it only be 30db, or would it be different?
Which one is the better choice? They're both the same price.
I know for a fact that the 2000RPM version is quieter than my stock H100i fans. So is that extra 3.69mm/h20 worth the 13.8db jump?
