Key Features

Further improved second generation of the iconic, award-winning NH-D15: Even better quiet cooling performance thanks to 8 heatpipes, 20% more surface area and novel NF-A14x25r G2 fans!
Specialised LBC (Low Base Convexity) version for optimal contact quality on relatively flat CPUs such as AMD AM5 (even without offset mounting), AM4 or Intel LGA2066 (optional NM-i20xx kit required), deluxe choice for Ryzen 9950X, 9900X, 9700X, 9600X, etc.
Caution: Not recommended for use on Intel LGA1700, LGA1200 or LGA115x! Please choose the regular NH-D15 G2 or the NH-D15 G2 HBC (High Base Convexity) version for these platforms!
Two state-of-the-art NF-A14x25r G2 140mm fans with speed-offset for acoustic fine-tuning, Low-Noise Adaptors and PWM for automatic speed control: maximum efficiency under load, near silent at idle!
Offset design with recessed lower fins clears top PCIe x16 on most current motherboards and offers 59mm RAM clearance in single fan mode (32mm with both fans, see Noctua Compatibility Centre)
