Noctua NH-D15S - Processor cooler - (for: LGA1156, AM2, AM2+, AM3, LGA1155, AM3+, LGA2011, FM1, FM2, LGA1150, FM2+, LGA2011-3, LGA1151, AM4, LGA1200) - aluminum with nickel plated copper base - 150 mm

PWM support and low-noise adapter. The NF-A15 fan supplied with the NH-D15S supports PWM for convenient automatic speed control through the motherboard. In addition, a high fan speed can be reduced using the supplied low-noise adapter for even quieter operation. High compatibility. This cooler uses an off-set, asymmetrical layout and a single fan. This allows the NH-D15S to provide state-of-the-art heatsink performance while maintaining high RAM and PCIe compatibility. SecuFirm2 mounting system. Noctuas SecuFirm2 mounting systems guarantees perfect contact pressure and advanced convenience on all current 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. Excellent component cooling. Extending below the fin-stacks, the large NF-A15 fan not only contributes to the high CPU cooling capabilities of the NH-D15S but also provides massive airflow over surrounding motherboard components and heatsinks, thus ensuring excellent component cooling performance.
