The Noctua NH-D15 G2 HBC is a precision-engineered version of the next-generation NH-D15, featuring High Base Convexity (HBC)—a contact surface optimized for CPUs with concave heatspreaders, such as AMD Ryzen 7000 (AM5) and Intel 13th/14th Gen (LGA1700) processors. Equipped with dual NF-A14x25r G2 PWM fans, adaptive mounting, and Sterrox® G2 aerodynamic advances, it offers unparalleled thermal performance and acoustic efficiency—tailored to the physical realities of today’s high-performance CPUs.

Key Features:

High Base Convexity base shape for enhanced contact with concave IHS (ideal for AM5 and LGA1700)

Dual-tower heatsink with asymmetrical fin-stack design for full RAM and PCIe compatibility

Equipped with 2 × NF-A14x25r G2 PWM fans featuring Sterrox® G2 material and aerodynamic refinement

Pre-applied NT-H2 compound and SecuFirm2™+ mounting system for fast, reliable installation

Mounting system pressure-tuned to maximize thermal transfer on modern socket geometries
