Noctua today released its long-awaited NH-D15 G2 next-gen flagship model CPU cooler and NF-A14x25r G2 round-frame 140mm fans. Continuing the legacy of the iconic NH-D15 and its NF-A15 fans, the new G2 products come packed with Noctua’s latest technologies and have been carefully refined in all respects to provide even better quiet cooling performance than their award-winning predecessors.

“Our G2 products have been years in the making and it feels amazing to finally be able to offer the first of them to our customers”, says Roland Mossig (Noctua CEO). “We faced various challenges in both design and manufacturing, but we’ve cut no corners and gone the extra mile to make sure that the G2’s will be worthy successors to some of our most iconic models. When you have them in your hands, I’m confident that you’ll be able to sense some of the dedication and perseverance that went into creating these fans and coolers.”

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.

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. Topped off with Noctua’s trusted 6-year manufacturer’s warranty, it’s the new number one choice for customers who demand the best of the best in air cooling.

Taking platform-specific optimisation to a new level, the NH-D15 G2 is available in a regular, standard version and two specialised variants: 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 LGA1700 CPUs when utilising the included NM-ISW1 shim washers (or optional, so-called contact frames ) to reduce CPU deformation from ILM pressure. The HBC (High Base Convexity) variant is specifically optimised for LGA1700 processors that are used with full ILM pressure or have become permanently deformed in long-term use, providing excellent contact quality despite the CPU’s concave shape. The LBC (Low Base Convexity) variant, by contrast, is specifically optimised for relatively flat CPUs. As such, it offers excellent contact quality on AMD AM5 even without the offset mounting as well as on other comparably flat CPUs (e.g. AM4, LGA2066, LGA2011(-3), lapped or custom flat heatspreaders, etc.).

For customers who would like to upgrade existing heatsinks such as the first-generation NH-D15, NH-D15S or NH-U14S series coolers, the new round-frame NF-A14x25r G2 fans will also be available separately, both in a regular single fan package (NF-A14x25r G2 PWM) and a dedicated dual fan package for push-pull configurations (NF-A14x25r G2 PWM Sx2-PP). Like the fans that come pre-installed on the NH-D15 G2, the ones included in the Sx2-PP set are fine-tuned with a 50rpm speed offset to prevent acoustic interaction phenomena such as periodic humming or intermittent vibrations.

The square frame version of the NF-A14x25 G2 fan for water cooling radiators and case cooling applications is currently scheduled for September.
