Noctua NH-D15 G2 Review & Specifications

The Noctua NH-D15 G2 by Noctua is a Air CPU cooler designed for compatibility with LGA 1851, LGA 1700, LGA 1151, LGA 1155, LGA 1156, LGA 1200, AM4, AM5 sockets.

This air cooler features a heatsink with a CPU contact base made of Copper, ensuring effective thermal conductivity. It includes 2 fan(s), each sized at 130 mm. These fan(s) can reach up to 1500 RPM and operate at a noise level of 24.8 dBA, delivering a combined airflow of 91.5 CFM. The total height of the cooler is 168 mm . Please ensure your PC case supports this cooler’s height. You can verify compatibility using our PC Builder, which filters compatible cases based on CPU cooler dimensions. This cooler does not include RGB lighting, focusing instead on performance, reliability, and low acoustic output. The cooler is backed by a 6-year warranty, providing long-term reliability and manufacturer support.

Performance

Noctua NH-D15 G2 is an ultra high-end performance air CPU cooler designed for CPUs with a TDP exceeding 200 W, achieving an outstanding relative cooling performance score of 93.18%. It is ideal for high-end gaming PCs and is especially recommended for professional workstations due to its superior reliability. As an air cooler, it has a simpler and more robust design compared to liquid coolers, which include additional components such as pumps and tubing that introduce more points of failure and potential leakage. Air coolers require minimal maintenance and typically have only one moving part — the fan. High-end models like this also offer significant passive thermal mass, which helps absorb heat even in the event of fan failure, providing a safety margin against hardware damage.

Cost-Effectiveness

The performance-per-price ratio of Noctua NH-D15 G2 is 22.9%, which places it in the lower tier of value for air coolers. However, as a high-performance air cooler, it may still be a worthwhile investment for enthusiasts or overclockers who prioritize thermal performance over cost-efficiency.
