What model of Noctua 120mm fans should I be using?

Henru · December 9, 2022

I recently bought this computer used:

The case is a NZXT s340 Razer edition.

It still has its standard case fan, one on the top and one on the back. They are kind of near each other so airflow is mostly in the top back corner. The fans are working but not super well, I can hear some noise and assume it’s time to swap them out just by age. I also want to add two fans to the front for better airflow through the case.

I really like Noctua’s fans but they have a lot of different options to choose from and I was hoping to choose what is optimal for my build. I plan on sticking with 120mm just so I have max comparability to bring them forward to future builds with me. I like the tan and brown please don’t judge me.

Any advice on a specific fan model noctua makes?

i have their NF-S12a fans, and i love them. theyre rediculously quiet but move a decent amount of air. The nf-a12x25 is the best all around from their lineup but can be somewhat pricey at 30-40$ per fan. the s12-a is more often 15-20$ per fan. the nf-s12 b is also a decent option and can be found for $15.

If youre not putting the fans in a tiny case or on a radiator/fin stack, youre most looking for a airflow optimised design rather than pressure optimised.
