Our Top Pick 2021
My top pick for case fans in 2021 has to be the NZXT AER RGB 2. A perfect balance between performance, noise, and aesthetics, the NZXT AER RGB 2 comes in both 120mm and 140mm sizes.

Beyond the aesthetic, the fan provides a static pressure airflow and uses the highest quality fluid dynamic bearings. These bearings run quieter and allow for a much longer lifespan than other bearing types. The only drawback here is the premium price it comes at. This fan is also our choice for the best RGB case fan 2021.

There is a similar fan from Noctua that comes in a Grey version, which in my opinion, looks much better than the brown version. This grey version, however, is a little bit louder.
