High-compatibility version of NH-D15 Compared to the award-winning NH-D15, the S-version uses an off-set, asymmetrical layout & 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 & PCIe compatibility. Excellent RAM compatibility Thanks to its recessed lower fins, the NH-D15S provides 65mm 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 not only on LGA115x & AMD, but also on LGA2011 where there are RAM slots on both sides of the socket. Asymmetrical layout for better PCIe compatibility As many current motherboards have the top PCIe x 16 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 x 16 slot on most current µATX & ATX motherboard. Please refer to our motherboard compatibility list for detailed information.

Having received more than 100 awards & recommendations from international hardware websites & magazines, Noctua’s compact NH-L9x 65 has become a standard choice among 65mm tall low-profile coolers. The SE-AM4 version is a dedicated special edition for AMD’s AM4 (Ryzen) platform featuring the latest Secu Firm 2 mounting system for AM4. Topped off with the renowned quiet NF-A9x 14 PWM 92mm fan, Noctua’s proven NT-H1 thermal compound & a full 6-year manufacturer’s warranty, the NH-L9x 65 SE-AM4 forms a complete premium-quality solution for AM4-based ITX builds & HTPC systems. Award-winning NH-L9x 65 cooler Tens of thousands of enthusiast users all over the world swear by the NH-L9x 65’s quality & performance. Recommended by more than 100 international hardware websites & magazines, it is renowned for being one of the best sub-70mm low-profile heatsinks on the market. Dedicated special edition for AM4 The NH-L9x 65 SE-AM4 brings the NH-L9x 65’s signature quiet cooling performance to AMD’s new AM4 platform. With its highly compact design & low profile, it is ideal for cooling lower TDP AM4 CPUs in HTPC or Small Form Factor cases. 65mm low profile Due to its compact heatsink & the 14mm thin NF-A9x 14 low profile fan, the NH-L9x 65 stands only 65mm tall (the same height as low-profile expansion cards), which makes it absolutely ideal to be used in compact HTPCs or Small Form Factor cases that offer limited clearance for CPU coolers. 100% RAM compatibility Being 95mm wide, the NH-L9x 65 SE-AM4 complies with the AMD AM4 socket’s keep-out zone. This means that it won’t cause issues with chipset coolers & doesn’t overhang the RAM slots, making it fully compatible with tall memory modules. 100% compatibility with PCIe cards on mini-ITX Many mini-ITX mainboards have the PCIe slot sitting close to the socket zone. While larger coolers with 120mm or 140mm fans that exceed this zone may block the PCIe slot, the compact NH-L9x 65 provides full compatibility with PCIe cards. Easy access to near-socket connectors Many low-profile coolers use larger fans or heatsinks in order to achieve sufficient cooling performance, but by protruding over the socket zone, they make it difficult or even impossible to reach near-socket connectors on tightly packed ITX mainboards. Thanks to its compact footprint, the NH-L9x 65 provides easy access to all connectors & components. NF-A9x 14 PWM premium fan The highly optimised NF-A9x 14 premium fan features Noctua’s proprietary AAO frame as well as sophisticated aerodynamic design measures. Supporting PWM for fully automatic speed control, the NF-A9x 14 allows the NH-L9x 65 to stay remarkably quiet. Low-Noise Adaptor Allowing to reduce the maximum speed of the NF-A9x 14 fan from 2500 to 1800 RPM, the included (L.N.A.) makes it possible to achieve near-silent setups using CPUs with up to 65W TDP. Secu Firm 2 mounting system for AM4 Noctua’s Secu Firm 2 mounting systems have become synonymous with quality, safety & ease of use. In order to achieve the best compatibility & to match the airflow path inside the case, the Secu Firm 2 mounting for AM4 makes it possible to install the cooler either in standard orientation or turned by 90° (motherboard dependant).
