About this item Further improved second generation of the iconic, award-winning NH-D15: Even better quiet cooling performance thanks to 8 heatpipes, 20% more surface area and novel NF-A14x25r G2 fans! Specialised HBC (High Base Convexity) version for optimal contact on strongly concave CPUs such as Intel LGA1700 (without washers or contact frames to reduce CPU warp), deluxe choice for 285K, 265K, 245K, etc. Caution: The HBC version is specifically optimised for LGA1700 with full ILM pressure. While it also works well on AMD AM5 using the included offset mounting, the regular or LBC version perform slightly better on AM5. Two state-of-the-art NF-A14x25r G2 140mm fans with speed-offset for acoustic fine-tuning, Low-Noise Adaptors and PWM for automatic speed control: maximum efficiency under load, near silent at idle! Offset design with recessed lower fins clears top PCIe x16 on most current motherboards and offers 59mm RAM clearance in single fan mode (32mm with both fans, see Noctua Compatibility Centre) Product Description The NH-D15 G2 is the further improved second generation of Noctua’s iconic NH-D15. With its state-of-the-art, speed-offset NF-A14x25r G2 PWM fans, eight heatpipes and asymmetrical fin-stacks that have been carefully fine-tuned to work in tandem with the new fans, it achieves even better quiet cooling performance than its award-winning predecessor. As such, the G2 version is a true flagship model that continues the legacy of the original NH-D15 by pushing the boundaries of air cooling and rivalling the efficiency of many all-in-one (AIO) water cooling solutions. Optimised for strongly concave CPUs, the specialised High Base Convexity (HBC) version provides excellent contact quality on Intel LGA1700 processors that are used with full ILM pressure or have become permanently deformed in long-term use. In addition to its further improved performance, the NH-D15 G2 also offers enhanced compatibility thanks to an offset construction that allows it to clear the top PCIe x16 slot on most current motherboards. Last but not least, the G2 version has been upgraded to the Torx-based SecuFirm2+ multi-socket mounting system with included NM-SD1 screwdriver as well as to Noctua’s superior NT-H2 thermal compound. In short, the NH-D15 G2 has been further refined in virtually all respects from the heatsink and the fans all the way down to the mounting, thermal paste and accessory package, making it an ideal choice for customers who demand the best of the best in air cooling. 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. Two NF-A14x25r G2 fans Noctua’s next-generation NF-A14x25r G2 fans set a new benchmark for performance-to-noise efficiency in round-frame 140mm fans. Their superb acoustics as well as their superior airflow and pressure characteristics are one of the cornerstones that enable the NH-D15 G2 to push beyond its legendary predecessor. Specialised HBC (High Base Convexity) version The High Base Convexity (HBC) version achieves optimal contact quality on CPUs that become strongly concave when the socket is closed due to the pressure of the ILM (Independent Loading Mechanism). As such, it is ideal for Intel LGA1700 processors if no washers or so-called contact frames are used to reduce ILM pressure or if the CPU has been permanently deformed in long-term use.
