NH-P1
In terms of thermal performance, the NH-D15 G2 stands out as the best air cooler currently available. At its maximum fan speed, it achieves an average thermal resistance of 0.0849 °C/W, surpassing the original NH-D15 and rivaling many dual-fan liquid coolers. Even at inaudible fan speeds, with the performance dip to 0.115 °C/W, it maintains exceptional cooling capabilities. This cooler is particularly suited for high-performance systems, offering remarkable efficiency and reliability, even under substantial thermal loads.
The acoustic performance of the NH-D15 G2 is equally noteworthy. Noctua's fan speed offset technique seems to be effective at reducing noise levels, with the cooler operating at a slightly quieter profile than its predecessor. At full speed, the noise output is 38.8 dB(A), which decreases to 33.3 dB(A) at half speed. Running the fans higher does lower the thermal resistance of the cooler measurably, allowing it to dissipate higher volumes of thermal energy efficiently, making the NH-D15 G2 highly suitable for high-wattage applications. The balance between cooling performance and noise levels is ideal for users seeking both power and quiet operation, allowing their systems to be quiet most of the time but with a cooling solution capable to handle massive thermal loads if need be.

"Noctua set out to build a halo product, and this is exactly what they've accomplished; putting together a chart-topping cooler with a superior build quality, thermal performance, and acoustic refinement." (E. Fylladitakis, Anandtech.com)
