Question Noctua NH-D14

[Lukhino]

Hello,
i have some question about new fans in my Noctua nh-D14.
I want to change these noctua fans (P12/P14) for some new in black color. Is arctic F12/F14 good choice?
I thing i need one 120mm fan in front and one 140mm in the middle.

You're in luck, Noctua launched black fans.

Back when they still had the specs on their website, F12 were rated only 30,000hrs of life, exactly the same as the typical sleeve-bearing fan and pretty bad for a hydro/fluid-dynamic bearing

Where did you find F12 has 30000hrs of life?
