Noctua NH D15 G2 LBC Air CPU Cooler:
The Noctua NH D15 G2 LBC Air CPU Cooler offers exceptional cooling performance, specifically optimized for relatively flat CPUs like AMD AM5 (even without offset mounting) and AM4. This dual-tower heatsink design comes equipped with two NF-A14x25r G2 PWM premium fans, ensuring quiet yet powerful operation. With broad socket compatibility for both Intel and AMD platforms, this cooler provides a versatile and high-performance solution for demanding CPUs. Furthermore, its robust construction and comprehensive accessories make it an ideal choice for enthusiasts.
Optimized Contact & Superior Cooling:
The Noctua NH-D15 G2 LBC (Low Base Convexity) variant is specifically optimized for relatively flat CPUs. This ensures excellent contact quality on AMD AM5 even without the offset mounting, as well as on other comparably flat CPUs (e.g., AM4, LGA2066, LGA2011, lapped or custom flat heatspreaders). This optimized base convexity maximizes thermal transfer efficiency.
Despite its size, the NH-D15 G2 delivers superior cooling performance. Its dual-tower heatsink design, combined with multiple heat pipes, efficiently dissipates heat from your CPU. The heatsink material consists of copper (base and heat-pipes) and aluminium (cooling fins), with soldered joints and nickel plating for optimal thermal transfer and durability. This robust construction ensures effective heat management even for demanding processors.
Quiet Operation with Dual NF-A14x25r Fans:
The Noctua NH-D15 G2 LBC comes equipped with two NF-A14x25r G2 PWM premium fans. These fans are renowned for their exceptional balance of high airflow and low noise. They operate at a maximum rotational speed of 1500 RPM, delivering an impressive airflow of 155.6 m³/h per fan. With the included NA-RC16 Low-Noise Adaptors (L.N.A.), the fan speed can be reduced to 1250 RPM, lowering the acoustical noise to just 19.7 dB(A) for ultra-quiet operation.
The fans utilize SSO2 bearings, which ensure long-term stability and quiet operation. Their Progressive-Bend impeller blade geometry further optimizes airflow and reduces noise. This focus on low noise levels, even under load, makes the NH-D15 G2 LBC an excellent choice for users who prioritize a quiet computing environment.
Broad Socket Compatibility & Comprehensive Accessories:
The Noctua NH-D15 G2 LBC offers broad CPU socket compatibility. It supports a wide range of Intel sockets, including LGA1851, LGA1700, LGA1200, LGA1156, LGA1155, LGA1151, and LGA1150. For AMD platforms, it is compatible with AM5 and AM4 sockets. This extensive compatibility ensures it fits a wide array of modern and older systems.
The cooler includes a SecuFirm2+™ multi-socket mounting system, renowned for its ease of use and robust contact pressure. This simplified installation process ensures a secure fit and optimal thermal transfer. The scope of delivery is comprehensive, including NT-H2 high-grade thermal compound, an NA-TPG1 thermal paste guard for AM5, and NM-ISW1 shim washers for LGA1700, providing excellent thermal conductivity and platform-specific optimizations right out of the box. A Torx® T20 screwdriver and Noctua metal case-badge are also included.
