Know before you buy
The HBC (High Base Convexity) version is designed for CPUs with a more pronounced integrated heat spreader, such as Intel LGA 1700 processors. The LBC (Low Base Convexity) version is specifically optimized for flatter CPUs, like AMD's AM5 and AM4, to ensure the best possible thermal contact.
The NH-D15 G2 features an asymmetrical design to improve clearance. With a single fan configuration, you get 59mm of RAM clearance, which accommodates most high-profile memory kits on the market.
No, the SecuFirm2+ system is designed for a straightforward installation. Each cooler includes the NM-SD1 Torx-head screwdriver, providing everything you need to mount the cooler securely to your motherboard.
The NH-D15 G2 is compatible with a wide range of modern sockets, including LGA 1700, LGA 1200, LGA 2066, AM5, and AM4. Please check your specific motherboard socket type against this list before purchasing to ensure compatibility.
The G2 utilizes the next-generation NF-A14x25r G2 PWM fans, which feature refined blade geometry and tighter manufacturing tolerances. These improvements allow for higher static pressure and better airflow efficiency compared to the original NF-A15 fans.
No, the cooler comes with a tube of Noctua's premium NT-H2 thermal compound. This high-performance paste is included in the box, so you have everything required for a professional-grade installation.
