The Noctua NH-D15 G2 (NH-D15 G2) represents the pinnacle of air cooling engineering. Continuing the legacy of the legendary NH-D15, the G2 version pushes performance further by incorporating eight high-capacity copper heatpipes, 20% more fin surface area, and next-generation 140mm fan technology to deliver elite-tier cooling for high-TDP CPUs without liquid maintenance risks.
Key Features
8 High-Performance Heatpipes: Expanded from six to eight heatpipes, the G2 copper heatpipe array dramatically improves heat distribution across both fin stacks under extreme thermal loads (300W+).
Dual NF-A14x25r G2 PWM 140mm Fans: Features Noctua's flagship round-frame fans made from Sterrox® Liquid Crystal Polymer (LCP) with a tight 0.7mm tip clearance. Built-in 50 RPM acoustic speed-offsets prevent harmonic humming caused by dual-fan setups.
Asymmetrical Dual-Tower Fin-Stacks: The fin-spacing has been reduced from 1.9mm to 1.6mm (adding 23 extra fins), while the front tower width is narrowed by 5mm to balance airflow loading between both fans.
Improved PCIe & RAM Clearance: Asymmetrical offset construction clears the top PCIe x16 slot on virtually all modern ATX and Micro-ATX motherboards. Offers 59mm of RAM clearance in single-fan mode or recessed multi-fan configurations.
SecuFirm2+™ Torx Mounting with AM5 Offset: Includes heavy-duty Torx T20 SecuFirm2+ mounting hardware, an NM-SD1 magnetic screwdriver, and dedicated offset mounting bars to target the thermal hotspot on AMD AM5 CPUs for up to 2°C lower temperatures.
Standard Convexity Base Plate: The standard version features a medium base convexity suited for general multi-socket setups and CPUs utilizing contact frames or moderate ILM pressure.
Premium Bundled Accessories: Comes pre-packaged with Noctua's high-grade NT-H2 thermal compound, NA-TPG1 thermal paste guard for AM5, Low-Noise Adapters (L-N.A.), and a solid metal Noctua case badge.
Performance & Reliability
Engineered in Austria, the soldered joints between copper heatpipes and aluminum fins ensure long-term thermal transfer efficiency over decades of use. Noctua backs the NH-D15 G2 with a 6-year manufacturer warranty.
Design & Aesthetics
Presented in Noctua's signature brown and beige acoustic heritage aesthetic, the nickel-plated copper base and heatpipes combined with raw aluminum cooling fins provide a classic, high-end finish.
Why This Product Stands Out
The Noctua NH-D15 G2 stands out by delivering AIO-level cooling performance backed by an 8-heatpipe design, 20% expanded fin surface area, and anti-resonance NF-A14x25r G2 140mm fans—eliminating liquid leakage risks while maintaining quiet operation.
