CPU Cooler NOCTUA NH-D15S:Relying on outstanding RAM and PCIe compatibility, the NH-D15S is the first version of the flagship NH-D15. Thanks to its specific design, the NH-D15S also comes with PCIe, providing rich PC graphics and high RAM memory modules . If you change components and need higher cooling performance, you can add a second passive fan.The passive section is interwoven with six copper HeatPipe tubes designed to improve heat dissipation from a copper base to a passive cooler where rapid cooling is achieved through an active fan. Using the LNA (Low-Noise-Adapter) adapter, noise and fan speed can be reduced. NT-H1 heat transfer paste for higher transfer efficiency from the processor to the base is included.Parameters and Specifications:Supported Sockets:Intel LGA2011-0 & LGA2011-3 (Square ILM), LGA1156, LGA1155, LGA1150AMD AM2, AM2, AM3, AM3 +, FM1, FM2, FM2 + (carrier required)Fan speed:Max. 1500 RPMMax.
