Optimised, asymmetrical fin-stacks
The NH-D15 G2 has been painstakingly optimised to best utilise the superior airflow and pressure performance of the novel NF-A14x25r G2 PWM fans. Thanks to the fans’ improved P/Q performance, the fin-spacing could be reduced from 1.9mm to 1.6mm, which made it possible to integrate 26 extra fins and increase total fin surface area by 20%. At the same time, the width of the front fin-stack has been cut by 5mm so that the loading is more balanced between the two fans.
More performance, smaller size
Thanks to the higher fin density made possible by the new NF-A14x25r G2 fans as well as the asymmetrical fin-stacks and a slightly smaller gap between the stacks, the G2 version combines improved performance with a slightly smaller size compared to the original NH-D15 (9mm less heatsink depth, same heatsink width, same total height including fans).
8 heatpipes for superior performance at higher heat-loads
The NH-D15 G2 utilises eight instead of six heatpipes compared to the original NH-D15. The increased thermal capacity of the extra heatpipes is especially helpful at extreme heat-loads such as 250W and beyond, where the performance boost over the original NH-D15 is the biggest.
Regular all-round version with medium base convexity
The regular NH-D15 G2 uses the same medium base convexity as most other Noctua heatsinks, which makes it a perfect all-rounder that provides optimal results on AM5 with the included offset mounting and on fresh, unused LGA1700 CPUs when utilising the included NM-ISW1 shim washers or so-called contact frames to reduce CPU deformation from ILM pressure.
High RAM compatibility in single fan mode
Thanks to its recessed lower fins, the NH-D15 G2 provides at least 59mm clearance for tall memory heatsinks in single fan mode, making it compatible with most high-end RAM modules on the market. In dual fan mode, the NH-D15 G2 should be used with standard height RAM (up to 32mm, please refer to RAM compatibility list)
Excellent component cooling
Extending below the fin-stacks, the large NF-A14x25r G2 fans not only contribute to the NH-D15 G2’s superb CPU cooling capabilities, but also provide massive airflow over surrounding motherboard heatsinks and components such as VRMs, thus ensuring excellent component cooling performance.
