The NH-D15 G2 is the further improved second generation of Noctuas 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 relatively flat CPUs, the specialised Low Base Convexity (LBC) version provides excellent contact quality on AMDs AM5 processors, even if the included offset mounting option isn nott used. 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.
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).
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.
Noctuas 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.
The Low Base Convexity (LBC) version achieves optimal contact quality on relatively flat CPUs. As such, it is ideal for AM5 even if the offset mounting isn't used or if users seek to combine the lowest possible CCD temperatures with the lowest possible IOD temperatures. The LBC version is also recommended for AM4, LGA2066 and LGA2011 (-3) (free-of-charge NM-i20xx mounting kit required), direct die applications as well as CPUs that have been lapped flat or outfitted with flat custom heat-spreaders.
