Noctua NH-D15S Multi Socket CPU Cooler

Tailored to provide superior RAM and PCIe compatibility, the NH-D15S is an asymmetrical single fan version of Noctua’s award-winning flagship model, the NH-D15. Thanks to its asymmetrical design, the NH-D15S clears the top PCIe slot on most µATX and ATX motherboards. At the same time, the single fan setup and recessed lower fins guarantee 100% RAM compatibility with memory modules of up to 65mm height. Users who have sufficient room can also upgrade the cooler with either a 120mm or round 140mm fan on the front fin stack for further improved performance in dual fan mode. 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-D15S forms a complete premium quality solution that combines dual tower efficiency with excellent compatibility and flexible upgrade options.

Overclock 3D Review
"Well, what can we say, in terms of traditional tower coolers, the high clearance, increased compatibility version of the mighty D15, with its off-set fin stack to improve GPU compatibility, 65mm of clearance underneath to decrease issues with high heat sink RAM, and only a single fan to further lessen RAM issues has totally wiped the floor with all but its bigger brother. We were expecting it to do well, but we really weren't expecting the results we got. Go back and have a look at the charts and you'll see that this cooler is only half a degree off the pace of the D15 at 4.4GHz and boasting a good few of the AIOs on the market." Full review

Modders-Inc. Review
"Just like the change from the NH-D14 to the NH-D15 seemed minor physically, closer inspection and testing revealed bigger changes than what can be observed by merely unboxing. It feels like Deja Vu with the NH-D15S but the improvements are surprisingly even more profound." Full review

NH-D15S

High-Compatibility Version of NH-D15

Compared to the award-winning NH-D15, the S-version uses an off-set, asymmetrical layout and a single instead of dual NF-A15 fans. This allows the NH-D15S to provide state-of-the-art heatsink performance while maintaining superior RAM and PCIe compatibility.

Excellent RAM Compatibility

Thanks to its recessed lower fins, the NH-D15S provides 66mm clearance for tall memory heatsinks, making it compatible with most high end modules on the market. As the lower fins are recessed on both sides of the heatsink, compatibility is excellent on both Intel and AMD sockets.

Asymmetrical Layout for Better PCIe Compatibility

As many current motherboards have the top PCIe x16 slot sitting close to the socket, bigger heatsinks tend to block it. Due to its asymmetrical layout, the fin-stack of the NH-D15S is off-set towards the upper edge of the motherboard when installed in standard orientation. This allows it to clear the top PCIe x16 slot on most current µATX and ATX motherboards.

NF-A15 140mm Fan

Complying with Noctua's AAO standard and featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A15 has quickly built up a reputation as one of the best 140mm fans on the market.

Dual-Fan Ready

Using the supplied extra fan clips, the NH-D15S can be upgraded with either a second round-frame 140mm fan with 120mm mounting holes (such as the NF-A15) for maximum performance or a common 120mm fan (such as the NF-F12) for improving performance while maintaining compatibility with RAM modules of up to 45mm height.

PWM Support and Low-Noise Adaptor

The NF-A15 premium fan supplied with the NH-D15S supports PWM for convenient automatic speed control through the motherboard. In addition, the maximum fan speed can be reduced from 1500 to 1200rpm using the supplied Low-Noise Adaptor for even quieter operation.

Excellent Component Cooling

Extending below the fin-stacks, the large NF-A15 fan not only contributes to the superb CPU cooling capabilities of the NH-D15S but also provides massive airflow over surrounding motherboard components and heatsinks, thus ensuring excellent component cooling performance.

SecuFirm2™ Mounting System

Noctua's SecuFirm2™ mounting systems have become synonymous with quality, safety and easy installation. Supporting Intel LGA1851, LGA1700 (since 2021), LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156) as well as AMD AM5 and AM4 (since 2019), the SecuFirm2™ mounting included with the NH-D15S is straightforward to install, provides perfect contact pressure and will stand the test of time even under heavy use.

Compatibility with Past and Future Sockets

Complying with the open SecuFirm™ standard, the NH-D15S can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, which is provided by Noctua free of charge. If technically possible, Noctua will also provide upgrade kits for future sockets.

NT-H1 Thermal Compound

Having received more than 100 awards and recommendations from hardware journalists around the world, Noctua's NT-H1 is a proven professional grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability.

6-Year Manufacturer’s Warranty

Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-A15 features an MTTF rating of more than 150,000 hours and the entire NH-D15S package comes with a full 6-year manufacturer’s warranty.
