Overview

The Noctua NH-D15 G2 is the highly anticipated successor to the legendary NH-D15. It refines the dual-tower design with new NF-A14x25r G2 fans and an improved fin stack, delivering a significant leap in both cooling performance and acoustic efficiency. This cooler is ideal for high-end gaming PCs and creator workstations that demand quiet, reliable air cooling.

Key Features

  • Dual-tower heatsink with eight heat pipes handles up to 280W TDP
  • Two NF-A14x25r G2 140mm fans with fluid dynamic bearings and advanced stator design for low noise and high airflow
  • Asymmetric fin layout minimizes RAM clearance issues – most high-profile memory modules fit without moving the fan
  • SecuFirm2+ mounting kit supports Intel LGA1851, LGA1700, LGA1200, LGA115x, AMD AM5, and AM4
  • Long-term support: Noctua offers free upgrade kits for future sockets

Compatibility Guide

  • Supported sockets: Intel LGA1851, LGA1700, LGA1200, LGA115x, AMD AM5, AM4
  • RAM clearance: 32mm with fans in default position; slide the front fan upward to accommodate taller modules (requires case width clearance)
  • Case width: Cooler height is 168mm – ensure your case has at least 180mm of clearance. Most mid-tower cases work fine
  • PCIe clearance: No interference with graphics cards due to the tower design

Ideal Builds

  • High-end gaming PC: Quietly cool an Intel Core i9-14900K or AMD Ryzen 9 7950X
  • Silent workstation: Avoid pump noise from AIOs while maintaining excellent thermal headroom
  • Enthusiast overclocking: 280W capacity handles moderate overclocks on flagship CPUs

Upgrade Considerations

  • Bottleneck: The cooler itself won't bottleneck your system, but poor case airflow will limit its effectiveness. Ensure adequate intake/exhaust fans
  • Overkill: For mid-range CPUs (Core i5, Ryzen 5), a cheaper NH-U12S or NH-D15S may suffice
  • RAM choice: If using tall RGB memory, verify clearance. The fan can be raised, but your case must have enough width
  • Case selection: Always check that your case supports a 168mm tall cooler. Most mid-towers do, but compact cases may not
