Noctua’s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua’s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan’s performance/noise efficiency.

Test verdict: "Noctua has raised the bar once more for high end air cooling products: the NH-D15 is without a doubt a stellar performer, in combination with the two included brilliant 140mm PWM fans it still keeps noise level reduced to a minimum. Even when running the D15 with a single centered fan the cooling performance is more than adequate to cool down your overclocked processors. Noctua has provided every accessory you need with this NH-D15, from the big thermal paste syringe to the Low Noise Adapters, everything you will need is included." (Albrecht Mesotten, Madshrimps.be)
