Hi forum. Kind of a noob question. I was thinking of replacing my CPU fan on my Cooler Master Hyper 212 EVO as it is growing old and starting to make noises. I was thinking maybe a Noctua NF-F12 or a Cougar CF-V12HPB. I am also wondering about the specs of the two fans. It says that the Cougar has a lower noise level at 17.9 dBA while the NF-F12 is slightly louder at 18.6 dBA.
Here is the part I don't understand. The units for air flow on both the Cougar and Noctua fans are different. Could someone just clarify what the difference is? If you could please give your preference on which one I should go for or if there is another fan you want to suggest I would appreciate it.
All feedback is appreciated
