Alright, before we dive into the article, first up is the Noctua press-release on the NH-D15:
"Having convinced tens of thousands of quiet cooling enthusiasts around the globe, our NH-D14 has become a reference for top-tier dual tower heatsinks", explains Mag. Roland Mossig, Noctua CEO. "In the end, it took us more than three years of continuous development, countless thermal simulations and over hundred samples to come up with a substantial improvement in efficiency. Staying true to our policy of not releasing anything we're not 100% satisfied with, we had to accept some delays in order to squeeze out the last few percent of performance, but now we're proud to finally release the NH-D15 as a worthy successor to the venerable D14."
With its expanded layout and dual NF-A15 fans, the NH-D15 further improves the D14's much acclaimed quiet cooling performance. Compared to the NH-D14, the NH-D15's fin-stack has been widened from 140 to 150 mm and its heatpipes are now spaced further apart, which allows for a more uniform heat distribution over a larger surface area and thus contributes to the NH-D15's superior efficiency. Thanks to its recessed lower fins, the NH-D15 provides 64mm clearance for tall memory heatsinks in single fan mode, making it compatible with high end RAM modules on the market.
The NF-A15 premium fans supplied with the NH-D15 support PWM for convenient automatic speed control through the mainboard. In addition, the maximum fan speed can be reduced from 1500 to 1200 rpm using the supplied Low-Noise Adaptor for even quieter operation.
Topped off with the trusted, pro-grade SecuFirm2 multi-socket mounting system, Noctua's proven NT-H1 thermal compound and full 6 years manufacturer's warranty, the NH-D15 forms a complete premium quality solution that represents a deluxe choice for overclockers and silent-enthusiasts alike.
