Noctuashowed off its highly anticipated next-generation NH-D15 CPU air cooler atComputex2024. The newNoctua NH-D15 G2is primed to claim the throne as the ultimate air cooler, but it has taken the firm a decade since the original NH-D15 succeeded the legendaryNH-D14to prepare this successor. Fundamental changes with the new NH-D15 G2 design include quieter fans, more heatpipes, a denser fin stack, and a new offset design. PC DIYers should be able to grab a new Noctua NH-D15 G2 later this month.
For a second-generation device coming a decade later, at first glance, the new NH-D15 G2 CPU air cooler doesn’t look a whole lot different from the 2014 original. It remains a dual-tower design in the coffee and cream (and silver) livery we expect. However, Noctua has quite a laundry list of changes that no doubt add up to create a more desirable G2 model.
The new selling points that Noctua wants to stress with the NH-D15 G2 are as follows:
Noctua also highlighted the inclusion of a Torx-based SecuFirm2+ mounting system (screwdriver provided) with an offset option for AM5 board users. Moreover, buyers will get a thermal paste guard forAM5 chipsand a set of NA-ISW1 shim-washers for improved contact onLGA1700. A shot ofNT-H2thermal paste is also provided, which is convenient.
Interestingly, Noctua also discusses three sub-variants of the NH-D15 G2, which vary by baseplate convexity. The standard NH-D15 G2 uses a medium base convexity, like a traditional heatsink from the firm. However, it will also offer the N H-D15 G2 LBC (Low Base Convexity) and NH-D15 G2 HBC (High Base Convexity). Some slides illustrating the merits of standard, LBC, and HBC contact profiles are provided below.
The Three Degrees
While we wait for the Noctua NH-D15 G2 to become available, readers must wonder what gains they could expect from this refined and modernized air cooler. According to Noctua’s testing, following the Noctua Standardized Performance Rating (NSPR) methodology, “the NH-D15 G2 performs 3.2°C better than the original NH-D15.”
Probably more impressive is the claim that the upcoming NH-D15 G2 can handle CPUs boosting 160W higher than its direct ancestor. According to Noctua, its next-gen cooler could holdCPU temperaturesat a stable 60 degrees Celsius for 15 minutes, even with a thermal load pushed past 600W.

In summary, the new NH-D15 G2 is claimed to be “easily Noctua’s best-performing model to date.” We look forward to getting one of these CPU air coolers in the labs and thoroughly testing it. Hopefully, the firm will stick to its touted ETA of June 2024.
