In addition you have an extension cord, noise reduction, a Y cable and an adapter 3-pin / molex! Yes this model is based on 3 pins and also comes with studs made of absorbent material to further reduce vibration in place of conventional screws.
I am a customer Noctua long time and I can compare, I even bought the last NF-A15 but I prefer this model!
Ps: Perfect for cooler Corsair Hydro Series 110.
