Fractal Design R5 Layout

[Kyle_101]

I know there are threads for this, but I have 2 extra 120mm fans I bought at the beginning when I was buying components. Should I even use them at all? This is what I have for my build.

Any help is much appreciated. This is my first build. Thanks!

It depends. if your airflow is adequate and your machine is cool, why add more noisemakers?
