NOCTUA – Asymmetrical Single-Fan Dual Tower CPU Cooler – 140mm PWM Fan – AM5 LGA1700 – NH-D15S

Uncompromising Dual-Tower Cooling Performance

The Noctua NH-D15S redefines what enthusiasts can expect from a premium air cooling solution. Engineered as the highly-compatible, asymmetrical single-fan counterpart to Noctua’s award-winning flagship NH-D15, this cooler expertly balances staggering thermal dissipation with exceptional motherboard and component clearance. At the heart of the NH-D15S is a robust 6-heatpipe dual-tower design that vastly increases the surface area for heat distribution. By pairing this massive thermal mass with the industry-leading SecuFirm2 mounting mechanism, builders are guaranteed optimal contact pressure and rapid heat transfer away from high-TDP processors across the most demanding workloads, gaming sessions, and professional rendering tasks.

Flawless PCIe and RAM Compatibility

System builders no longer have to compromise between raw cooling power and component fitment. The Noctua NH-D15S features a precision-engineered asymmetrical layout. The entire fin stack is deliberately offset toward the upper edge of the motherboard when installed in the standard orientation, completely clearing the top PCIe slot on the vast majority of micro-ATX and standard ATX motherboards. Furthermore, the lower fins of the heatsink are intelligently recessed. This specific architectural choice guarantees 100% RAM compatibility, seamlessly accommodating modern RGB memory modules and tall memory heatsinks up to 65mm in height without any physical interference.

Whisper-Quiet NF-A15 PWM Acoustics

Cooling performance is only half the equation; managing acoustics is equally critical. The NH-D15S is driven by the state-of-the-art NF-A15 140mm premium fan, renowned for its incredible airflow-to-noise ratio. Equipped with automated PWM support, the fan intelligently scales its rotational speed based on the CPU temperature, remaining virtually silent during idle tasks while spinning up only when necessary under heavy load. For users demanding absolute silence, the included NA-RC7 Low-Noise Adaptor (L.N.A.) further caps the maximum fan speed, creating an almost inaudible acoustic profile perfect for recording studios and quiet workstation environments.

Future-Proof Expansion and Pro-Grade Reliability

The NH-D15S is designed to adapt to your evolving system requirements. For users operating within spacious chassis who want to extract even more thermal headroom, the package conveniently includes extra fan clips. This allows for a swift dual-fan upgrade using either an additional 120mm or round 140mm front-mounted fan. Installation is secure and frustration-free thanks to the trusted SecuFirm2 multi-socket mounting system, supporting an extensive array of modern AMD (AM5, AM4) and Intel (LGA1700, LGA1851, and more) sockets. Topped off with Noctua’s proven NT-H1 thermal compound and backed by a full 6-year manufacturer’s warranty, the NH-D15S stands as an undisputed premium-quality investment for any high-performance PC build.
