The Noctua NH-D15 G2 LBC is the Low Base Convexity variant of the second-generation NH-D15, tailored specifically for CPUs with flatter heatspreaders, such as select Intel LGA1851 and LGA1700 engineering samples or custom-lapped AM5 processors. Featuring twin NF-A14x25r G2 PWM fans, an advanced fin-stack layout, and next-gen Sterrox® G2 frame materials, it offers silent thermal dominance while maximizing mounting contact on flatter IHS surfaces.

Key Features:

Low Base Convexity design for optimal contact on flat or custom-lapped CPU heatspreaders

Equipped with 2 × NF-A14x25r G2 PWM fans for high static pressure and ultra-quiet operation

Refined dual-tower architecture with asymmetrical layout for RAM and PCIe clearance

Adaptive SecuFirm2™+ mounting system and pre-applied NT-H2 thermal compound

Designed for high-end desktop CPUs requiring silent performance with precise thermal conduction

Specifications:

• Dimensions (with fans): 165 x 150 x 144 mm

• Weight (with fans): ~1360 g

• Materials: Copper (base and heatpipes), aluminium (fins), nickel-plated, soldered joints

• Compatibility:

  • Intel LGA1851 / LGA1700 (ideal for flat IHS or delidded CPUs)

  • AMD AM5 / AM4 (lapped or pre-delidded CPUs)

• Fans: 2 × NF-A14x25r G2 PWM

• Fan Speed: 500–2000 RPM ±10%

• Airflow: up to 140.2 m³/h

• Static Pressure: 3.60 mm H₂O

• Acoustics: max. ~31.5 dB(A)

• Connector: 4-pin PWM

• Max TDP: 250W+ (CPU and case-dependent)

Additional Features:

• Precision-machined cold plate curvature for flat-die contact

• Enhanced thermal conductivity with pre-applied NT-H2 compound

• Offset fin design maintains compatibility with tall RAM and wide GPUs

• Built for silent high-load operation in overclocked and professional builds

• Fully modular fan system with additional mounting clips included

Customer Benefits:
The NH-D15 G2 LBC is the ideal cooling solution for builders who use CPUs with flat IHS surfaces—whether delidded, lapped, or naturally flat. With its tailored base curvature, dual Sterrox® G2 fans, and acoustic optimization, it delivers maximum cooling efficiency for enthusiast systems with surgical precision.
